, Description:TECHNICAL FIELD
[0001] The present disclosure relates generally to the field of circuit breakers. In particular, the present invention relates to a circuit breaker with a double latch mechanism with an interlock component to ensure efficient charge and discharge operations, whilst not over stressing the motor.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] A circuit breaker typically serves two basic purposes: first, as a switching device for switching between ON and OFF, during normal operating conditions, and second, as a protection device for tripping or isolating circuits during abnormal conditions such as short-circuit, overload and under voltage.
[0004] For high end operations where electric supply needs to be reinstated in a very short span of time or while swapping ends between two supplies, a stored energy operating mechanism is mounted on the circuit breaker and used to release energy required to close the contacts of the circuit breaker and reinstate the supply. The stored energy operating mechanism is one such device wherein a combination of mechanisms for accumulating and storing mechanical energy is used to close the primary contacts of the circuit breaker. The energy can be input to the mechanism manually or by means of a motor. The mechanism includes a series of linkages which utilize the energy to close the primary contacts and also to maintain the closing force upon the primary contacts. They also functioning to allow rapid contact opening when desired.
[0005] Motor operators are mainly used to drive circuit breakers from a remote location through electrical input. They can be of two types - direct drive operator and stored energy operator. In case of direct drive operator, motor energy is used in both ways, for closing and opening the circuit breaker. In case of stored energy operator, the motor energy is used to open the circuit breaker, in which the spring assembled in the system is charged and allowed to store energy through various mechanical means. The stored energy is discharged during closing of the circuit breaker contacts.
[0006] Stored energy operator has two modes of operation: Manual and Auto. Manual mode consists of a charging unit and the handle attached to it, so that cranking system provided allows the circuit breaker to be driven from ON to OFF and a manual OFF button allowing the unit to discharge the energized spring through various linkages mechanically connected. Auto mode consists of motor charging the spring and driving the unit from ON to OFF and input from remote location discharges the energized spring through mechanical linkages connected below.
[0007] United States patent 6130392 describes a stored energy circuit breaker operator with an operating handle of a circuit breaker contains springs that store energy when charged and that release energy when discharged. Energy is stored when a movement translation assembly is moved in a charging direction by an operator gear, and stored energy is released when a release apparatus releases the operator gear, causing the movement translation assembly to move in a discharging direction.
[0008] United States patent 6166343 describes a unidirectional clutch assembly for use with an operator handle, pinion shaft assembly, a worm gear assembly and a pinion gear assembly of a stored energy assembly for use with a circuit breaker assembly.
[0009] United States patent 6192718 describes a key lock and locking hasp assembly used for a stored energy circuit breaker operator assembly. It is provided with an electrical control module for use with a stored energy circuit breaker assembly having a motor for use with a circuit breaker assembly, the circuit breaker assembly providing an electrical signal through electrical contacts for actuating the circuit breaker assembly.
[0010] United States patent 4042896 describes a manual and motor operated circuit breaker. It is provided with a circuit function which is adapted for either manual or motor driven operation, as desired. Motor driven operation is achieved by the incorporation of a power unit comprising a motor selectively drivingly coupled to the circuit breaker operating mechanism and operating to charge the mechanism spring incident to closing the breaker contacts. Upon completion of a charging function, a closing solenoid is energized to effect release of the stored energy, which powers the breaker contacts to their closed position.
[0011] In the prior art described above, the motor driver is connected directly to the mechanical driven systems during the charging operation of the circuit breaker, making the mechanism susceptible to jamming after the knob travel stops. This jamming leads to an increased force requirement for subsequent switching operations.
[0012] There is therefore a requirement in the art for a circuit breaker with a mechanism that does not cause jamming and that also works to make switching operations more efficient and reliable.

SUMMARY
[0025] The present disclosure relates generally to the field of circuit breakers. In particular, the present invention relates to a circuit breaker with a double latch mechanism with an interlock component to ensure efficient charge and discharge operations, whilst not over stressing the motor.
[0026] The present invention discloses a circuit breaker which can be used in automatic mode of operation. The operation involves the charging and discharging of a compressed spring during switching operations by the circuit breaker.
[0027] In an aspect of the present invention, the charging of the compression spring is done through a motor. The rotary motion of the motor is converted to a linear motion through a series of gearing mechanisms including an epicyclic gear train, a worm gear unit and a rack and pinion assembly. As the rack advances, the spring, along a spring guide, gets charged.
[0028] In another aspect of the invention, the epicyclic gear train has the advantage that the stress of transfer of rotary motion is distributed evenly among all the gear teeth, thereby reducing stress concentration and increasing life of the gear.
[0029] In another aspect of the present invention, the epicyclic gear train reduces the motor speed and thereby increases capacity for torque in the system. A second, and important function of the epicyclic gear train is that it maintains the unidirectionality of transmission of motion.
[0030] In another aspect of the present invention, during charging, the secondary latch is lifted and, due to spring action, the main latch is engaged with the planet gear. This shifts the charging load from the secondary latch to the main latch, thereby causing the force required to open the secondary latch to be lower.
[0031] In another aspect of the present invention, during discharge operation, the secondary latch is disengaged from the planet gear. In order to ensure this disengagement, an interlock component is introduced, which holds the secondary latch in place during the entirety of the discharge operation.
[0032] In contrast to the existing prior art literature, the present invention discloses a circuit breaker with a latch mechanism that ensures efficient and complete switching of said circuit breaker during operation. The invention also discloses a mechanism whereby the motor is not over stressed and the torque transmitting capability of the system is increased with the use of an epicyclic gear train and worm gear unit.
[0033] Various objects, features, aspects and advantages of the inventive subject matter will become more apparent from the following detailed description of preferred embodiments, along with the accompanying drawing figures in which like numerals represent like components.

[0047] Various terms as used herein are shown below. To the extent a term used in a claim is not defined below, it should be given the broadest definition persons in the pertinent art have given that term as reflected in printed publications and issued patents at the time of filing.
[0048] The present disclosure relates generally to the field of circuit breakers. In particular, the present invention relates to a circuit breaker with a double latch mechanism with an interlock component to ensure efficient charge and discharge operations, whilst not over stressing the motor.
[0049] The present invention discloses a circuit breaker which can be used in automatic mode of operation. The operation involves the charging and discharging of a compressed spring during switching operations by the circuit breaker.
[0050] In an aspect of the present invention, the charging of the compression spring is done through a motor. The rotary motion of the motor is converted to a linear motion through a series of gearing mechanisms including an epicyclic gear train, a worm gear unit and a rack and pinion assembly. As the rack advances, the spring, along a spring guide, gets charged.
[0051] In another aspect of the invention, the epicyclic gear train has the advantage that the stress of transfer of rotary motion is distributed evenly among all the gear teeth, thereby reducing stress concentration and increasing life of the gear.
[0052] In another aspect of the present invention, the epicyclic gear train reduces the motor speed and thereby increases capacity for torque in the system. A second, and important function of the epicyclic gear train is that it maintains the unidirectionality of transmission of motion.
[0053] In another aspect of the present invention, during charging, the secondary latch is lifted and, due to spring action, the main latch is engaged with the planet gear. This shifts the charging load from the secondary latch to the main latch, thereby causing the force required to open the secondary latch to be lower.
[0054] In another aspect of the present invention, during discharge operation, the secondary latch is disengaged from the planet gear. In order to ensure this disengagement, an interlock component is introduced, which holds the secondary latch in place during the entirety of the discharge operation.

[0056] FIG. 1 illustrates an exploded view of the full mechanism (100) of the circuit breaker. In an aspect of the present invention, the full mechanism (100) comprises a motor (16), a compression spring (7), a gear assembly, a latching system and a toggle system.
[0057] In another aspect of the present invention, the gearing system is a multi-gear assembly, further comprising a sun or spur gear (1), a worm gear unit (4), a pinion (11) and rack (13) assembly and an epicyclic gear train (300).
[0058] In another aspect of the present invention, the worm gear unit (4) further comprises a spur gear (4A), a worm wheel (4B), a unidirectional bearing (4C) and a worm gear (4D).
[0059] In another aspect of the present invention, the epicyclic gear train (300) further comprises a sun gear (1), planet gears (2) and an internal gear (14), wherein the internal gear (14) has a ratchet profile.
[0060] In an embodiment of the present invention, the spur gear (4A), worm wheel (4B) and a worm gear (4D) are made of phosphor bronze and the unidirectional bearing (4C), sun gear (1) and the epicyclic gear train (300) are made of thermoplastic materials.
[0061] In an instance, during the automatic “switching off” operation of the circuit breaker, the worm gear unit (4) is driven by the motor (16). The worm gear unit (4) then undergoes rotary motion, specifically, the worm wheel (4B) drives the spur gear (4A) into rotating, and in turn, the spur gear (4A) transmits the rotary motion to the sun gear (1).
[0062] In another aspect of the present invention, upon being driven by the motor (16), the worm gear unit (4) undergoes rotation and this reduces the speed of the motor, thereby increasing the torque transmission capacity.
[0063] In another aspect of the present invention, the rotary motion of the sun gear (1) is transmitted to the epicyclic gear train (300). In particular, the sun gear (1) engages with the planet gear (2), which, in turn, transmits rotary motion to the internal gear (14), through its ratchet profile.
[0064] The epicyclic gear train (300) has the advantage that the stress of transfer of rotary motion is distributed evenly among all the gear teeth, thus reducing stress concentration and increasing life of the gear. The epicyclic gear train (300) causes further reduction in motor (16) speed, thereby further increasing capacity for torque in the system. A second, and important function of the epicyclic gear train (300) is that it maintains the unidirectionality of transmission of motion. This function is particularly pertinent during OFF-ON switching operation of the circuit breaker, where spring discharge energy is utilized for the switching operation and the reverse loading of the motor at this juncture is to be prevented to avoid stressing the motor.
[0065] During the ON-OFF operation, however, motor loading is required and here, the sun gear (1) engages with the epicyclic gear train (300) to transmit torque. Further, the epicyclic gear train (300) is coupled to the pinion (11) and rack (13) assembly and transmits rotary motion thereto.
[0066] FIG. 2 illustrates the secondary latch arrangement in the operating mechanism of a circuit breaker. In an aspect of the present invention, during charging operation, the worm gear unit (4) drives the sun gear (1), which, in turn, transmits the rotary motion to the planet gear (2). The ratchet profile of the planet gear (2) is stopped by the pawl or main latch (3), due to which the internal gear (14) starts rotating.
[0067] In another aspect of the present invention, the internal gear is connected to the pinion (11) and rack (13) arrangement, through the main shaft (9). As a result, as the internal gear (14) starts rotating, the pinion (11) starts rotating, causing the rack (13) to move forward. As the rack (13) proceeds to move, the compression spring (7) starts getting charged. The compression spring (7) continues to get charged until it reaches the end of travel slot, at the side plate (8).
[0068] In an embodiment of the present invention, the internal gear (14) has a projection (14A), and during charging of the circuit breaker, the projection (14A) is used to keep the main latch (3) lifted and the secondary latch (21) engaged to the planet gear (2).
[0069] FIG. 3 illustrates the planet gear (2) assembly along with the main latch (3) during charging operation of the proposed circuit breaker mechanism.
[0070] FIG. 4 illustrates the travel of rack (13) and the consequent charging compression spring (7).
[0071] FIG. 5 illustrates the engagement of the main latch (3) and the disengagement of the secondary latch (21) with respect to planet gear (2), during charging operation.
[0072] In another embodiment of the present invention, before the complete charging of the proposed circuit breaker, the projection on the internal gear (14A) is used to lift the secondary latch (21). At that moment, due to spring action, the main latch (3) gets engaged with the planet gear (2). The load at the beginning of the charging operation is on the secondary latch (21) and when it is lifted by the internal gear projection (14A), the load gets reduced on the secondary latch (21). Hence, during discharge operation, the force needed to open the secondary latch (21) is low.
[0073] Generally, during discharging operations, the complete discharge of the circuit breaker assembly is often incomplete as the secondary latch (21) falls after the charging operation and prevents full discharge. This results in an inability of the circuit breaker to switch ON.
[0074] In another embodiment of the present invention, during the discharge operation of the proposed circuit breaker, the secondary latch (21), after being lifted during charging operation, gets locked by a secondary latch locking mechanism (22), and is held locked until the discharge operation is complete. This ensures that that the secondary latch (21) is disengaged from the planet gear (2), consequently ensuring a complete discharging operation.
[0075] In another embodiment of the present invention, the latch locking mechanism (22) includes an interlock component (24). To prevent possible, intermittent engagement of the secondary latch (21) with planet gear (2) during discharge operation, an interlock component (24) is introduced, which holds the secondary latch (21) until discharge operation is complete.
[0076] In another embodiment of the present invention, during discharge operations of the proposed circuit breaker, a solenoid (20) disengages the main latch (3) and the supportive latch link (18) to ensure complete disengagement from the planet gear (2), until discharge operation is complete.
[0077] FIG. 6 illustrates the releasing of interlock (24) after discharge operation, by rack right pin (25).
[0078] In another embodiment of the present invention, once the rack (13) reaches the end of its travel, after discharge, the rack right pin (25) slides the interlock component (24), allowing the secondary latch (21) to once again engage with the planet gear (2), for the next charging operation.
[0079] The present invention is a circuit breaker that can be used for automatic switching operations in a circuit. Also, the circuit breaker has an efficient charging and discharging operation by utilizing a double latch mechanism with interlock components.
