DESC:TECHNICAL FIELD
[001] The present subject matter described herein, in general, relates toelectrical switching devicesand more particularly to breaking current and clearing fault currents in switchgears in any switching device or circuit breaker using arc quenching technologies.

BACKGROUND
[002] An electrical switching device may be defined as a unit designed to make, carry and breakelectrical supply so as to protect the equipments connected in the electrical circuit from damage caused by overload, under-voltage or short circuit etc. Circuit breakers are well-known electrical switching devices used to provide automatic circuit interruption, when circuit fault conditions occur.
[003] In an event of fault, current is interrupted in a monitored circuit. A separable pair of contact such as a moveable contact and a stationary contact separates from their original closed position so as to create a space between them. This result in the formation of an electrical arc at the time the contacts are separated.As long as this arc is sustained in between the contacts the current through the circuit breaker will not be interrupted finally as because arc is itself a conductive path of electricity. The electrical arcerodes the contacts and therefore reduces the life of the circuit breaker. Therefore, for total interruption of current by a circuit breaker it is essential to quench the arc as quickly as possible.
[004] Currently, the technology which is being used in switchgear for arc quenching uses an arc quenching chamber for lengthening and splitting of arc. An arc chute assembly is designed with specific intention for efficient and quick arc quenching. The faster the arc is quenched the better is the electrical life of the breaker.
[005] The arc chute assembly consists of stack of splitter plates made up of magnetic material to attract, split-up and cool the arcs generated when the contacts are separated out. The stack of splitter plates is trapped in between two plates known as side plate made up of electrically insulating material. The function of splitter plates is to split the arc in several series arcs of approximately equal length which will result in higher arc voltage and distinctly greater dielectric strength after current zero. Since the splitter plate or deion plate system interrupts current by cooling of arcs and splitting of arcs into a series of sub-arcs orsplit-arcs or arclets and by developing arc voltage greater than the system voltage, thus for reliable interruption of an electrical arc, the splitter plates should allow and promote smooth and fast movement of arc into the splitter plates and not allow or preventsmovement of arc either downward toward contact gap or upward toward the vent region above the splitter plates. Thus design of arc splitter plates in arc chamber assembly is essential for effective quenching of arc.
[006] Most prior art have limitations of unstable retention of arc in arc chute assembly or in the splitter plate region due to the use flat metallic or ferromagnetic splitter plates in the arc chute assembly with or without some profile cut on it provided with a variable shape, size, profile and thickness of the splitter plates.Usually by splitting the arc between the splitter plates the arc voltage is developed. So the existing mechanisms trend greatly depends on the splitting of the arc between splitter plates for effective arc quenching. The disadvantage of the existing mechanisms is that the arc quenching process is not efficient, development of arc voltage is less and sluggish especially in the initial part of splitting phase. In this case there lies apossibility of improper arc quenching or standing arc above splitter plates, if the arc energy has not been decreased significantly, dielectric strength is not fullyregained by arc chamber and development of arc voltage is not sufficient to quench the arc.Most prior and current flat plate designs of splitter plates have limitations of improper arc quenching, unstable retention of arc in the arc chute assembly or splitter plate region. Rapid ejection of sub-arcs or arclets permits a reuniting of the sub-arcs into the vent space, thus forming a single arc or a lesser number of arclets and thus standing arc or sustainable arc form.
[007] A rapid ejection of sub-arcs or arclets permits a reuniting of the sub-arcs into the vent space, forming a single arc or a lesser number of arclets and thus resulting into standing arc or sustainable arc .The arc quenching process is not efficient as the development of arc voltage is less and sluggish especially in the initial part of splitting phase due to comparatively small arc lengthening.. In this case also there lies a possibility of standing arc above splitter plates, if the arc energy has not been decreased significantly, dielectric strength is not fully regained by arc chamber and development of arc voltage is not sufficient to quench the arc.Also due to the current path in the splitter plates Lorentz force can be in the upward or downward direction. Due to downward Lorentz force on arc there can be sustained arc or standing arc above contact gap region or at the bottom of splitter plates region which further reduces the short circuit breaking capability of arc chute chamber/assembly. Due to these drawbacks, the electrical life of the breaker subsequently reduces.
[008] Thus, in view the hitherto drawbacks of the existing arc chute assembly with flat splitter plates, there exists a dire need to provide an improved arrangement of arc chute assembly/chamber that improves the arc quenching behavior and thus provides enhanced short circuit breaking performance in an electrical switching device such as circuit breaker, a motor circuit breaker or contactor.

SUMMARY OF THE INVENTION
[009] The following presents a simplified summary of the invention in order to provide a basic understanding of some aspects of the invention. This summary is not an extensive overview of the present invention. It is not intended to identify the key/critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some concept of the invention in a simplified form as a prelude to a more detailed description of the invention presented later.
[0010] An object of the present invention is to provide an arc chute assemblywith an improved arc splitter platesfor better arc quenching in electrical switching deviceand that obviates the above drawbacks of the existing arc chute assembly with a flat splitter plates.
[0011] Another object of the present invention is to provide an improved arc splitter plates in arc chute assembly that uses a combination of metallic plate or ferromagnetic splitter plates with electrical insulating plate or electrical insulating material cap at the bottom of the splitter plate toward the contact gap in the arc chute assembly so as to improve the electrical arc quenching performance.
[0012] Yet another object of the present invention is to provide an improved arc splitter plates that generates high and fast arc voltage after arc enters into the arc splitter plates so as to reduce the total arcing time and thus providing faster arc quenching.
[0013] Still another object of the present invention is to provide an improved arc quenching behavior in the electrical switching device by using splitter plates made of at least one of a material selected from a group of mild steel and/or ferromagnetic metal and the like, of suitable thickness so as to generate a pull force on the arc and to withstand the arc energy.
[0014] Still another object of the present invention, improve the electrical arc quenching performance in terms of greater arc voltage development by lengthening of arc, fast development of the arc voltage in the initial phase of splitting. The greater penetration length or the inserted length of the metallic or ferromagnetic plate into the electrical insulating plate or into the electrical insulating material cap helps to increase the pull force on arc.
[001] Accordingly, the present invention provides an arc chute assemblycomprising arc splitter plates that provides a better arc quenching in the electrical switching device.
[002] In one implementation, the present invention provides anarc chute assembly in an electrical switching device comprising atleast two splitter plates wherein each of the splitter plates uses a combination of metallic or ferromagnetic splitter plates with electrical insulating plate or electrical insulating material cap so as to improve the electrical arc quenching performance in terms of greater arc voltage development by lengthening of arc, fast development of the arc voltage in the initial phase of spitting of arc, reducing the possibility of standing arc or sustained arc in the vent space or in the contact gap region.
[003] In one implementation, the present invention provides a metallic or ferromagnetic splitter plates with electrical insulating plate or electrical insulating material cap at the bottom of the splitter plate toward the contact gap wherein the splitter plates mentioned in the invention can be used along with other splitter plates which can beselected from at least one of single or multiple metallic or ferromagnetic flat plate splitter plates, single or multiple metallic or ferromagnetic long splitter plates or any other combinations thereof, with or without a profile cut with any arrangement and in any numbers. The splitter plates improve the arc quenching behavior in an arc chute assembly or other similar arrangement.
[004] In one implementation, the present invention provides a splitter plate that uses a combination of metallic or ferromagnetic splitter plate with electrical insulating plate or electrical insulating material cap at the bottom of the splitter plate toward the contact gap in the arc chute assembly so as to improve the electrical arc quenching performance in terms of greater arc voltage development by lengthening of arc, fast development of the arc voltage in the initial phase of splitting. The greater penetration length or the inserted length of the metallic or ferromagnetic plate into the electrical insulating plate or into the electrical insulating material cap helps to increase the pull force on arc. Due to the unique profile, shape and use of the combination of ferromagnetic and electrical insulating material in the same splitter plate in the arc chute assembly, higher arc voltage develops in the initial phase of splitting. The splitter plates ensure effective quenching of arc in the arc chute assembly by developing sufficient arc voltage by lengthening of arc, fast development of the arc voltage in the initial phase of splitting and reducing the chance of rapid ejection of arclets into the vent space and the chance of sustained arc or standing arc in the vent space area due to improper arc quenching because of insufficient arc voltage development and very high arc speed. This also prevents the downward movement of arc in the arc chute assembly and ensures the interruption of the arc in the arc chute assembly itself, thus avoids the accumulation of arc and related arc cloud and gases in the contact gap region.
[005] In one implementation, the present invention provides metallic or ferromagnetic splitter plate with electrical insulating plate or electrical insulating material cap at the bottom of the splitter plate toward the contact gap using the combination of ferromagnetic and electrical insulating material in the same splitter plate wherein the generated arc takes a path in between the electrical insulating plate or electrical insulating material cap thus elongating itself. This helps in developing high arc voltage due to lengthening of arc in the initial phase of splitting when arc enters into the arc chute assembly and thus helps in efficient arc quenching. Before arc takes the path through the splitter plates in the splitting phase, it takes the zigzag path in between the electrical insulating portion of the splitter plates, thus elongating and lengthening enough to have higher arc voltage at the initial phase of splitting. The elongation and lengthening of arc depends upon the vertical length of the electrical insulating plate or electrical insulating material cap above the contact gap. Due to the ferromagnetic material above the electrical insulating plate or electrical insulating material cap, in the splitter plate, the arc experiences the force in the upward direction. Also the greater penetration length or the inserted length of the metallic or ferromagnetic plate into the electrical insulating plate or into the electrical insulating material cap helps to increase the pull force on arc.
[006] Due to the electrical insulating plate or electrical insulating material cap and due to the greater penetration length or the inserted length of the metallic or ferromagnetic plate into the electrical insulating plate or into the electrical insulating material cap, the length of the splitter plate or metallic or ferromagnetic plate in the arc chute assembly is extended to a greater depth or to a greater length above the contact gap region. This additional ferromagnetic material mass and length due to the greater penetration length or the inserted length of the metallic or ferromagnetic plate into the electrical insulating plate or into the electrical insulating material cap helps to increase the pull force on arc. The upward force ensures the adequate lengthening of the arc at the bottom of the splitter plate and then proper arc splitting and creation of arc lets in the ferromagnetic or metallic zone of the arc chute thus ensuring effective and efficient arc quenching. Due to the use of electrical insulating material, the vertical length of the splitter plate in the arc chute assembly is extended above the contact gap region. This helps in improving the breaking performance and the electrical life of the breaker. The vertical length of the metallic core ferromagnetic plate is greater (2 to 5 times) than the vertical length of the electrical insulating plate or electrical insulating material cap and this ratio of the vertical length of the metallic or ferromagnetic plate to the electrical insulating plate or electrical insulating material capcan be of any value, as per requirement.
[007] In one implementation of the present invention provides a metallic or ferromagnetic splitter plate with electrical insulating plate or electrical insulating material cap at thebottom of the splitter plate toward the contact gap using the combination of ferromagnetic and electrical insulating material in the samesplitter plate increases the force on arc after the arc enters into the arc chute assembly. Due to the elongated arc path distribution inbetween the electrical insulating plate or electrical insulating material caps, arc experiences higher force in the upward direction due toLorentz force. This helps in fast arc movement in the upward direction and arc voltage development in comparison to the flat plate splitter platecase. Also this ensures the fast and proper movement and lengthening or elongation of the arc into the arc chuteassembly.
[008] In one implementation, the present invention provides a metallic or ferromagnetic splitter plates with electrical insulating plate or electrical insulating material cap at the bottom of the splitter plate toward the contact gap using the combination of ferromagnetic and electrical insulating material in the same splitter plate wherein the Lorentz force help to prevent the downward movement of the arc. So it reduces the chance of downward movement of split arc, thus reducing the chance of sustained arc or creating a standing arc above the contact region by joining of split arc lets. In this case, due to the formation of arc root and arc lets at a later stage in the splitting phase in the metallic or ferromagnetic material zone above the electrical insulating plate or electrical insulating material cap section, it helps to prevent very fast upward movement of arc as initially only arc lengthening and related arc voltage development is there in the insulating plate or insulating cap section. Thus ensuring the quenching of arc in the arc chute assembly thus reducing the chance of sustained arc or standing arc in the vent space region above the splitter plates by joining of split arc lets. This way, it prevents the very fast upward movement and downward movement of arc in the arc chute assembly and ensures the interruption of the arc in the arc chute assembly itself. This avoids the accumulation of arc and related arc cloud and gases in the contact gap region, avoids occurrence of standing arc or sustained arc in the contact gap or in the venting area above splitter plate. Also due to the upward Lorentz force after arc enters into the splitter plate region, arc achieves fast movement in the upward direction, thus helping the contact gap region to regain the dielectric strength by fast movement of arc into the arc chute assembly from the nearby contact gap area.
[009] In one implementation, the present invention provides a metallic or ferromagnetic splitter plate with electrical insulating plate or electrical insulating material cap at the bottom of the splitter plate toward the contact gap using the combination of ferromagnetic and electrical insulating material in the same splitter plate wherein the greater penetration length or the inserted length of the metallic or ferromagnetic plate into the electrical insulating plate or into the electrical insulating material cap helps to increase the pull force on arc, as additional ferromagnetic material mass and length is added to the splitter plate compared to the otherwise normal ferromagnetic flat splitter plate. Due to the electrical insulating plate or electrical insulating material cap and due to the greater penetration length or the inserted length of the metallic or ferromagnetic plate into the electrical insulating plate or into the electrical insulating material cap, the length of the splitter plate or metallic or ferromagnetic plate in the arc chute assembly is extended to a greater depth or to a greater length above the contact gap region. This additional ferromagnetic material mass and length due to the greater penetration length or the inserted length of the metallic or ferromagnetic plate into the electrical insulating plate or into the electrical insulating material cap helps to increase the pull force on arc. The gap between two splitter plates in the arc chute assembly is selected as per requirement and facilitates the elongated and zigzag arc path near and in between the splitter plates.
[0010] In one implementation, the present invention provides ametallic or ferromagnetic splitter plate with electrical insulating plate or electrical insulating material cap at the bottom of the splitter plate toward the contact gap using the combination of ferromagnetic and electrical insulating material in the same splitter plate wherein the metallic plate or ferromagnetic plate is of suitable thickness so as to generate the pull force on the arc and to withstand the arc energy and to withstand attraction or repulsion force due to high current.
[0011] The present inventionensures the quenching of arc in thearc chute assembly by developing sufficient arc voltage by lengthening of arc, fast development of the arc voltage in the initialphase of splitting and reducing the chance of rapid ejection of arclets into the vent space and reducing the chance of sustained arc orstanding arc in the vent space area due to very high arc speed. It prevents the downward movement of arc in the arcchute assembly and ensures the interruption of the arc in the arc chute assembly itself. This avoids the accumulation of arc andrelated arc cloud and gases in the contact gap region, avoids occurrence of standing arc or sustained arc in the contact gap region.
[0012] In one implementation, the present invention, that is metallic or ferromagnetic splitter plate with electrical insulating plate or electrical insulating material cap at the bottom of the splitter plate toward the contact gap can be of any other similar shaped or similar fashioned splitter plate using the combination of ferromagnetic and electrical insulating material in the same splitter plate at any required and preferable position, pattern and with or without any profile cut on it.
[0013] In one implementation, the present invention, that is metallic or ferromagnetic splitter plate with electrical insulating plate or electrical insulating material cap at the bottom of the splitter plate toward the contact gap in the arc chute assembly, can also be used, with or without single or multiple flat plate or bent metallic or ferromagnetic splitter plates, single or multiple long splitter plates or any other single or multiple similar shaped or similar fashioned splitter plates with or without any particular profile cut, in the arc chute assembly in any combination, in any arrangement and in any number to improve the arc quenching performance.
[0014] Accordingly, in one implementation, an arc chute arrangement for arc quenching in electrical switching device is disclosed. The arc chute arrangement comprisesat least one splitter plate having at least one metallic splitter plate with at least one electrical insulating plate or electrical insulating material cap present at least at one end of the metallic splitter plate toward a contact gap in the arc chute assembly arrangement wherein usage of a combination of the ferromagnetic and the electrical insulating material in the same splitter plate increases a force on an arc after the arc enters into the arc chute assembly.
[0015] In one implementation, an arc chute arrangement for arc quenching in electrical switching device is disclosed. The arc chute arrangement comprisesat least one metallic splitter plate with at least one electrical insulating plate or electrical insulating material cap present at least at one end of the metallic splitter plate toward a contact gap in the arc chute assembly arrangement.

[0079] Referring now to figure 11a and figure 11c, in one implementationLorentz force on the arc in between two metallic or ferromagnetic only splitter plates due to the particular current path is illustrated.
[0080] Referring now to figure 11b, in one implementation the Lorentz force generated on the arc and lengthening of arc in between two splitter plates, having combination of metallic or ferromagnetic splitter plate andelectrical insulating plate or electrical insulating material cap at the bottom of the same splitter plate toward the contact gap, due to the particular current path because of the splitter plate with combination of metallic or ferromagnetic plate and electrical insulating plate is illustrated. Here at the bottom of the splitter plate or in the electrical insulating plate region the Lorentz force is in the upward direction along with comparatively greater lengthening of arc.
[0081] Referring now to figure 11d, in one implementation the Lorentz force on the arc and lengthening of arc in between two splitter plates, having combination of metallic or ferromagnetic splitter plate andelectrical insulating plate or electrical insulating material cap at the bottom of the same splitter plate toward the contact gap, due to the particular current path because of the splitter plate with combination of metallic or ferromagnetic plate and electrical insulating material cap is illustrated. Here at the bottom of the splitter plate or in the electrical insulating material cap region the Lorentz force is in the upward direction along with comparatively greater lengthening of arc. The greater penetration length or the inserted length of the metallic or ferromagnetic plate into the electrical insulating material cap helps to increase the pull force on arc, as additional ferromagnetic material mass and length is added to the splitter plate compared to the otherwise normal ferromagnetic flat splitter plate. Due to the electrical insulating material cap and due to the greater penetration length or the inserted length of the metallic or ferromagnetic plate into the electrical insulating material cap, the length of the splitter plate or metallic or ferromagnetic plate in the arc chute assembly is extended to a greater depth or to a greater length above the contact gap region. This additional ferromagnetic material mass and length due to the greater penetration length or the inserted length of the metallic or ferromagnetic plate into the electrical insulating material cap helps to increase the pull force on arc. Gap between two splitter plates, having combination of metallic or ferromagnetic splitter plate andelectrical insulating plate or electrical insulating material cap at the bottom of the same splitter plate toward the contact gap, in the arc chute assembly is selected as per requirement and facilitates the elongated and zigzag arc path near and in between the splitter plates.
[0082] In one implementation, the metallic or ferromagnetic splitter plates with electrical insulating plate or electrical insulating material cap at the bottom of the splitter plate toward the contact gap using the combination of ferromagnetic and electrical insulating material in the same splitter plate, arc takes the path in between the electrical insulating plate or electrical insulating material cap thus elongating itself. This helps in developing high arc voltage due to lengthening of arc than the normal flat plate metallic only splitter plates in the initial phase of splitting when arc enters into the arc chute assembly, thus resulting in efficient arc quenching. Before arc takes the path through the splitter plates in the splitting phase, it takes the zigzag path in between the insulating portion of the splitter plates, thus elongating and lengthening enough to have higher arc voltage at the initial phase of splitting unlike in the only ferromagnetic flat splitter plates. The elongation and lengthening of arc depends upon the vertical length of the electrical insulating plate or electrical insulating material capat the bottom part of splitter palte, the current invention, above the contact gap. Due to the ferromagnetic material above the electrical insulating plate or electrical insulating material cap, in this combination splitter plate, arc experiences the force in the upward direction like the otherwise normal ferromagnetic flat splitter plate due to magnetic field and magnetic flux line distribution. Also the greater penetration length or the inserted length of the metallic or ferromagnetic plate into the electrical insulating plate or into the electrical insulating material cap helps to increase the pull force on arc, as additional ferromagnetic material mass and length is added to the splitter plate compared to the otherwise normal ferromagnetic flat splitter plate. Due to the electrical insulating plate or electrical insulating material cap and due to the greater penetration length or the inserted length of the metallic or ferromagnetic plate into the electrical insulating plate or into the electrical insulating material cap, the length of the splitter plate or metallic or ferromagnetic plate in the arc chute assembly is extended to a greater depth or to a greater length above the contact gap region. This additional ferromagnetic material mass and length due to the greater penetration length or the inserted length of the metallic or ferromagnetic plate into the electrical insulating plate or into the electrical insulating material cap helps to increase the pull force on arc. The upward force ensures the adequate lengthening of the arc at the bottom of the splitter plates and then proper arc splitting and creation of arc lets in the ferromagnetic or metallic zone of the multiple splitter plates in the arc chute assembly thus ensuring effective and efficient arc quenching. Due to the use of insulating material, the vertical length of the splitter plate in the arc chute assembly is extended above the contact gap region and the vicinity of splitter plates and the contact gap region improves. This helps in improving the breaking performance and the electrical life of the breaker. The vertical length of the metallic cor ferromagnetic plate is greater (2 to 5 times) than the vertical length of the electrical insulating plate or electrical insulating material cap andthis ratio of the vertical length of the metallic or ferromagnetic plate to the electrical insulating plate or electrical insulating material cap can be of any value, as per requirement.Gap between two splitter plates, having combination of metallic plate or ferromagnetic splitter plates with electrical insulating plate or electrical insulating material cap at the bottom of the splitter plate toward the contact gap, in the arc chute assembly is selected as per requirement and should facilitate the elongated and zigzag arc path near and in between the splitter plates.
[0083] In one implementation, the metallic or ferromagnetic splitter plates with electrical insulating plate or electrical insulating material cap at the bottom of the splitter plate toward the contact gap using the combination of ferromagnetic and electrical insulating material in the same splitter plate increases the force on arc after the arc enters into the arc chute assembly. Due to the elongated arc path in between the electrical insulating plate or electrical insulating material caps, arc experiences higher force in the upward direction due to Lorentz force. This helps in fast arc movement and arc voltage development in comparison to the flat plate only ferromagnetic splitter plate case. Also this ensures the fast and proper movement and lengthening or elongation of the arc into the arc chute assembly.
[0084] In one implementation, the Lorentz force by using metallic or ferromagnetic splitter plates with electrical insulating plate or electrical insulating material cap at the bottom of the splitter plate toward the contact gap using the combination of ferromagnetic and electrical insulating material in the same splitter plate, helps to prevent the downward movement of the arc. So it reduces the chance of downward movement of split arc, thus reducing the chance of sustained arc or creating a standing arc above the contact gap region by joining of split arc lets. In this case also, due to the formation of arc root and arc lets at the later stage in the splitting phase in the metallic or ferromagnetic material zone above the electrical insulating plate or electrical insulating material cap section, it helps to prevent very fast upward movement of arc. The metallic or ferromagnetic splitter plates with electrical insulating plate or electrical insulating material cap at the bottom of the splitter plate toward the contact gap using the combination of ferromagnetic and electrical insulating material in the same splitter plate, arc takes the path in between the electrical insulating plate or electrical insulating material cap thus elongating itself. This helps in developing high arc voltage due to lengthening of arc than the normal flat plate metallic only splitter plates in the initial phase of splitting when arc enters into the arc chute assembly, thus resulting in efficient arc quenching. Before arc takes the path through the splitter plates in the splitting phase, it takes the zigzag path in between the insulating portion of the splitter plates, thus elongating and lengthening enough to have higher arc voltage at the initial phase of splitting unlike in the only ferromagnetic flat splitter plates. Thus ensuring the quenching of arc in the arc chute assembly itself, thus reducing the chance of sustained arc or standing arc in the vent space region above the splitter plates by joining of split arc lets. This way, it prevents the upward and downward movement of arc in the arc chute assembly and ensures the interruption of the arc in the arc chute assembly itself. Also due to the upward Lorentz force after arc enters into the bottom part of the splitter plate region that is in the electrical insulating material plate or electrical insulating material cap region, arc achieves fast movement in the upward direction. This avoids the accumulation of arc and related arc cloud and gases in the contact gap region, thus helping the contact gap region to regain the dielectric strength by fast movement.
[001] In one implementation, the height, width, distance between the two splitter plates and number of splitter plates is selected suitably as per the requirement in the arc chute assembly. Also geometric shape and dimensions like penetration length or the inserted length of the metallic plate or ferromagnetic plate into the electrical insulation plate or electrical insulating material cap, shape, profile and width of the inserted metallic or ferromagnetic plate and the shape, profile and width of the groove or profile in the electrical insulating plate or electrical insulating material cap is selected as per requirement.
[002] In one implementation, the electrical insulating plate or electrical insulating material cap is selected from at least one of a material selected from a group of Nylon 6, 6 Polytetrafluoroethylene or PTFE or any other suitable ablative or non-ablative, arc resistant, flame retardant and melt-deform resistant electrical insulating material.
[003] In one implementation, the combination of, metallic or ferromagnetic splitter plate with electrical insulating plate or electrical insulating material cap at the bottom of the splitter plate toward the contact gap can be of any other similar shaped or similar fashioned splitter plate using the combination of ferromagnetic and electrical insulating material,wherein the metallic or ferromagnetic plate and electrical insulating plate or electrical insulating material capis assembled together by insert fitment or any other fitment process and design. At the bottom of the metallic splitter plate, at least one fitment profile is provided and the electrical insulating plate or electrical insulating material capis fitted or assembled to the metallic plate by using at least one of a fitment process or design selected from sliding or inserting the fitment groove in the electrical insulating material plate or electrical insulating material cap throughout the fitment profile along the horizontal length of the plate or other fitment process available as per requirement.
[004] In one implementation, the metallic splitter plates is plated using at least one of the material selected from a group of zinc or any suitable material plating as per requirement. These plates may or may not have serration on surface.
[005] In one implementation, the strength, thickness and the fitment of the electrical insulating plate or electrical insulating material capis tobe adequate enough to withstand the arc energy and electro-dynamic forces. The splitter plates and the robust assembly of splitter plates in the side plates of arc chute assembly provide the required mechanical strength.
[006] In one implementation, the splitter plates with or without symmetrical or unsymmetrical profile cut with respect to x, y and z axis is arranged in symmetrical profile position or in alternative profile position in an alternative splitter plate arrangement as per requirement. The surfaces of the two plates of the same splitter plate, that is metallic or ferromagnetic plate and electrical insulating plate or electrical insulating material cap, fitted in the bottom of the metallic or ferromagnetic plate, is designed to align properly so to have a smooth continuous surface for proper arc propagation.
[007] In one implementation, the present invention is metallic or ferromagnetic splitter plate with electrical insulating plate or electrical insulating material cap at the bottom ofthe splitter plate toward the contact gap using the combination of ferromagnetic and electrical insulating material in the same splitter plateincreases the force on arc after the arc enters into the arc chute assembly. Due to the elongated zigzag arc path in between the electrical insulating plate or electrical insulating material caps, arc experiences higher force in the upward direction due to Lorentz force. This helps in fast arcmovement and greater arc voltage development in comparison to the flat plate only ferromagnetic splitter plate case. Also this ensures the fast and propermovement and lengthening or elongation of the arc into the arc chute assembly.
[008] In one implementation, due to high and fast arc voltage development after arc enters into the splitter plates, total arcing time reduces. It helps in better arc quenching.
[009] In one implementation, the gap between two splitter plates in the arc chute assembly can be as per requirement and should facilitate the elongated and zigzag arc path near and in between the splitter plates.
[0010] In one implementation, thematerial of the ferromagnetic metal, material of the electrical insulating plate or electrical insulating material cap, vertical length or height ratio of the metallic or ferromagnetic plate and electrical insulating plate or electrical insulating material cap, penetration length or the inserted length of the metallic or ferromagnetic plate into the insulating plate or into the insulating material cap, thickness and dimension of the metallic or ferromagnetic plate and electrical insulating plate or electrical insulating material cap, type and thickness of plating on the metallic or ferromagnetic plate and electrical insulating plate or electrical insulating material cap, shape, hinge and groove or fitment profile and profile of the metallic or ferromagnetic plate and electrical insulating plate or electrical insulating material cap, gap between two splitter plates and number of plates in the arc chute assembly, manufacturing and engineering processes to manufacture the metallic or ferromagnetic plate, electrical insulating plate or electrical insulating material cap and the present invention, that is metallic or ferromagnetic splitter plates with electrical insulating plate or electrical insulating material cap at the bottom of the splitterplate toward the contact gap, can vary as per requirement and as per breaking capacity to achieve similar design concept and itsadvantages and any suitable combination, features and type of these parameters and processes can be adapted as perrequirement and as per breaking capacity.
[0011] In one implementation,these splitter plates can be assembled between side plates in the arc chute assembly. Any other effective arrangement of assembly to incorporate the splitter plate and splitter plate assembly also can be possible.
[0012] The surfaces of the two plates in the splitter plate, that is metallic or ferromagnetic plate and electrical insulating plate or electrical insulating material cap, fitted in the bottom of the metallic plate, should be designed to align properly so to have a smooth surface for proper arc propagation.
[0013] Some of the important features of the present invention, considered to be noteworthy are mentioned below:
1. The additional ferromagnetic material mass and length due to the greater penetration length or the inserted length of the metallic or ferromagnetic plate into the electrical insulating material cap helps to increase the pull force on arc due to magnetic field and magnetic flux lines distribution.
2. The present invention of a metallic or ferromagnetic splitter plate with electrical insulating plate or electrical insulating material cap at the bottom of the splitter plate toward the contact gap in the arc chute assembly improves the electrical arc quenching performance in terms of greater arc voltage development by lengthening of arc, fast development of the arc voltage in the initial phase of splitting of arc in the arc chute assembly. Before arc takes the path through the splitter plates in the splitting phase, it takes the zigzag path in between the insulating portion of the splitter plates, thus elongating and lengthening enough to have higher arc voltage at the initial phase of splitting.
3. In one implementation of the present invention provides a metallic or ferromagnetic splitter plate with electrical insulating plate or electrical insulating material cap at the bottom of the splitter plate toward the contact gap using the combination of ferromagnetic and electrical insulating material in the same splitter plate increases the force on arc after the arc enters into the arc chute assembly. Due to the elongated arc path distribution in between the electrical insulating plate or electrical insulating material caps, arc experiences higher force in the upward direction due to Lorentz force.Due to the unique profile, shape and use of the combination of ferromagnetic and electrical insulating material in the same splitter plate in the arc chute assembly, higher arc voltage develops due to lengthening of arc, fast development of the arc voltage in the initial phase of splitting of arc. It ensures the quenching of arc in the arc chute assembly by developing sufficient arc voltage and reduces the chance of rapid ejection of arclets into the vent space and the chance of sustained arc or standing arc in the vent space area due to very high arc speed.
4. Due to high and fast arc voltage development after arc enters into the splitter plates, total arcing time reduces. It helps in better arc quenching.

The additional ferromagnetic material mass and length due to the greater penetration length or the inserted length of the metallic or ferromagnetic plate into the electrical insulating material cap helps to increase the pull force on arc.Also due to the upward Lorentz force after arc enters into the bottom part of the splitter plate region that is in the electrical insulating material plate or electrical insulating material cap region, arc achieves fast movement in the upward direction. It prevents the downward movement of arc in the arc chute assembly and ensures the interruption of the arc in the arc chute assembly itself.This avoids the accumulation of arc and related arc cloud and gases in the vicinity of contact gap region, thus helping the contact gap region to regain the dielectric strength by fast movement.
6. Due to the electrical insulating material cap and due to the greater penetration length or the inserted length of the metallic or ferromagnetic plate into the electrical insulating material cap, the length of the splitter plate or metallic or ferromagnetic plate in the arc chute assembly is extended to a greater depth or to a greater length above the contact gap region. Due to the use of insulating material, the vertical length of the splitter plate in the arc chute assembly is extended above the contact gap region and the vicinity of splitter plates and the contact gap region improves.
