, Description:TECHNICAL FIELD
[0001] The present disclosure relates to a stored energy operator (SEO), and more specifically relates to, a mechanism to indicate a correct indication state of a stored energy operator (SEO).

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] Use of electrical devices is well known for making, breaking and to provide safety in a typical electrical distribution system. These devices get mounted inside a board or panel board for added safety to the operator. Most often these devices are required to be operated either from outside or by opening the enclosure/ panel. In view of operator’s safety, remote operation is an alternative way to operate the switching devices. Usually to achieve this, an add-on accessory is mounted over the switching device, which may operate the device when called for.
[0004] Also in today’s scenario response time for an electrical switching system to switchover from one desired source to the other is gaining importance. Thus with a view of lesser operational time and remote operation of a switching device, stored energy type of motor mechanism are used.
[0005] Motor operators also referred to as electrical operating mechanism (hereinafter referred as “EOM”), is mainly used to drive MCCB from a remote location through electrical input. EOM can be of two main types, direct drive operator and stored energy operator. In case of direct drive operator, motor energy is used in both ways of closing and opening the MCCB. In case of stored energy operator, the motor energy is used in the direction of ON-OFF movement, which means opening of MCCB, 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 the OFF-ON motion, which means closing of MCCB contacts. 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 onto the handle allows customer to drive the MCCB from ON-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-OFF and input from remote location discharges the energized spring through mechanical linkages connected below.
[0006] Stored energy operator serves two basic purposes. As a switching device: On/Off during normal operating conditions for the purpose of operation and maintenance. As a protecting device: Tripping or Isolating by breaking the contacts interrupting the fault current during abnormal conditions such as short-circuit, overload and under voltage. Stored energy electrical operating mechanism (hereinafter referred as “SE-EOM”) is also supposed to meet the standard and Foot print requirements of basic breaker. MCCB being the governing element, with preset boundary conditions and constraints, SE-EOM has to perform primary, secondary and tertiary functions in a determined manner.
[0007] The stored energy operator (SEO) which is used in combination with a MCCB. The SEO is generally used in changeover applications leading to switching of electrical supplies between mains and auxiliary. A standalone SEO and MCCB combination also works in the application of motorized MCCB’s. A stored energy operator works in two principle states of charged state and discharged state. The charged state is the one in which the MCCB is switched OFF and supply is OFF, in this state the spring of the SEO is elongated and is stored with energy. To switch ON the MCCB and the power supply, the spring is discharged and the SEO shows a discharged indication. The SEO is operated in two states of automatic operation and manual operation; therefore there is a need to indicate the charged indication in the manual operation.
[0008] Efforts have been made in related art to address above stated problem by using a mechanism or device. An example of such of the mechanism is recited in a United States Patent 6192718, entitled “Key lock and locking hasp assembly for a stored energy circuit breaker operator assembly”. The patent discloses Locking mechanisms incorporated in the switch assembly and operable by a key or a special tool. The patent describes a cylinder key lock and locking hasp assembly for use with a stored energy assembly, having a housing and an operator mechanism that may be manually actuated, for use with a circuit breaker assembly, the cylinder lock and locking hasp assembly comprising a cylinder key lock mounted in the stored energy assembly housing, wherein the cylinder key lock extends into the stored energy assembly housing and wherein at least a portion of the cylinder key lock may be moved when actuated, and further wherein the at least a portion of cylinder key lock may be moved to at least one unlocked position or to at least one locked position; a cylinder lock arm, wherein the cylinder lock arm is used to secure one end of said cylinder key lock in the stored energy assembly housing and wherein key actuated movement of the cylinder lock also causes the cylinder lock arm to move to at least one corresponding unsecuring position or to at least one securing position; a lifting member comprising a mounting member and a securing lifting member, wherein movement of the cylinder lock arm causes movement of the lifting member to at least one corresponding unsecured position or to at least one secured position; a locking hasp assembly, mounted in the stored energy assembly housing, comprising a locking hasp receiving member and a locking hasp securing member having an aperture for receiving the lifting member.
[0009] However, in the conventional techniques such as key lock and locking hasp assembly for a stored energy circuit breaker operator assembly there is no way talks about interlocking of the state. Further, the conventional techniques for SEO are inefficient and complex in nature.
[00010] Whereas there is certainly nothing wrong with existing techniques, nonetheless, there still exists a need to provide an efficient, effective, reliable, and improved stored energy circuit breaker operator assembly using cam based interlocking feature. Further, there is a need of a mechanism or double ball catch mechanism to indicate correct indication state of a stored energy operator. Furthermore, there is a need of a mechanism or device to indicate the correct indication of the charged state of Miniature Circuit Breaker (MCCB) during manual operation.

[00065] FIG. 1 illustrates combination of a SEO (1) mounted on top of the MCCB (.2), in accordance with an exemplary embodiment of the present disclosure.
[00066] FIG. 1 illustrates the combination of a SEO (1) mounted on top of the MCCB (.2). A generic application of a SEO is when it is mounted atop the MCCB and operates the MCCB when the mechanism of the SEO engages with the KNOB of the MCCB.
[00067] FIG. 2 illustrates a proposed invention, in accordance with another exemplary embodiment of the present disclosure.
[00068] FIG. 2 shows all the features available to the customer showing essential operational parameter for the combination, the auto-manual slider (3) which is used to change the state of the SEO, the charged/discharged indication window (4) which shows the state of the SEO whether in charged or in discharged state, the ON/OFF indication window(5) which shows the state of the MCCB, The charging handle (6) can be used to charge the mechanism when the auto manual slider (3) is in manual mode. The handle (6) is used to switch off the MCCB (1) and bring the SEO in charged condition.
[00069] FIG. 3 illustrates a mechanism of the SEO without the cover, in accordance with another exemplary embodiment of the present disclosure.
[00070] FIG. 3 shows the mechanism of the SEO without the cover, in which the motor (7) becomes the prime mover and drives a gear train (8) which is further coupled to a rack (9) which translates the rotary motion to linear motion, the rack is coupled with the MCCB and the motion of the motor switches it OFF. The rack further is attached to a spring which charges the spring with energy to be used to switch ON the device during changeover. To charge the pin the gear train (8) is also attached to a teethed cam (10) which is further attached to the latch (11), the latch also interacts with the D-shaft (12). During manual charging, the handle (6) makes the Rack (9) to move by manual operation by interacting with the gear train (8) and consequently charging the spring in the various strokes of manual operation. The movement of the rack pushes the lift lever (13) which in turn pushes the charge/discharge lever (15)). This charge/discharge lever (15) is operationally coupled to the see saw lever (16) which in turn is coupled to the indication flag (17). The end movement of the rack ensures the operational channel is activated and the indication flag (17) shows a charged indication through the window (4). For every charging stroke of the handle (6) the rack (9) moves back a little owing to the tendency of the spring to come back to its original state and the working clearance between the teethed cam (10) and the latch (11) and the D shaft (12).
[00071] FIG. 4 illustrates a side view of the EOM without the base, in accordance with another exemplary embodiment of the present disclosure.
[00072] FIG. 4 shows the side view of the EOM without the base. The view shows the movement of the Rack (9) towards the charged end of the EOM. In doing so, the leg (9A) of the rack actuates the lift lever (15) and the other leg (9B) operates the toggle switch (18). The toggle switch is an electrical cutoff system which stops the operation during automatic operation.
[00073] FIG. 4 also, shows the position of the rack (9) before it has operated the toggle switch (18). At this moment the EOM is not charged and the charged indication should not come and so the charge/discharge lever (15) is still in its original place.
[00074] FIG. 5 illustrates a charged state of the SEO, in accordance with another exemplary embodiment of the present disclosure.
[00075] As shown in FIG. 5, the charged state of the SEO, this is also apparent by the displacement of the charged discharged lever (15) which moves up when the pin (9A) makes the lift lever (13) to move up. What also can be made out from the image is that the end position of the rack (9) stays the same before and after the complete charging of the EOM owing to the tendency of the rack to come back due operational clearance and the tendency of the spring to come back to its original state.
[00076] FIG. 6 illustrates a spring loaded plunger, in accordance with another exemplary embodiment of the present disclosure.
[00077] As shown in FIG. 6, a spring loaded plunger (19) which is mounted on a base (20) and is fixed on the LHS plate (14). The spring loaded plunger (19) can move back and forth and is positioned behind the lift lever (13).
[00078] FIG. 7 illustrates a lift lever (13) being placed above the spring loaded plunger (19), in accordance with another exemplary embodiment of the present disclosure.
[00079] Figure 7 shows the lift lever (13) being placed above the spring loaded plunger (19). The lift lever rotates and the holes on the lift lever are so positioned that when the lift lever rotates, the two holes cross the plunger. The holes are so designed that the spring loaded plunger does not pass through from the hole but acts as an obstruction to ensure the lift lever cannot move because of the ball catch action. Here the spring loaded plunger (19) _ acts as the ball and the holes of the lift lever (13) acts as the catch.
[00080] FIG. 8 illustrates how the rack leg (9a) makes the lift lever (13) to rotate and ensure that the spring loaded plunger (19) catches into the rightward hole), in accordance with another exemplary embodiment of the present disclosure.
[00081] Figure 8 shows how the rack leg (9a) makes the lift lever (13) to rotate and ensure that the spring loaded plunger (19) catches into the rightward hole. Due to this catch, the charge/discharge lever (15) stays in its position and the charge indication is visible on the window (4) .even though the rack (9) has gone back. Also, during discharging, the leg (9B) of the rack (9) starts moving back and hits the leg (13A) of the lift lever (13) in doing so, the lift lever (13) moves anticlockwise and the spring loaded plunger (19) catches into the leftward hole of the lift lever (19). Owing to this, the rack pin (9A) will never interfere with the leg (13A) of the lift lever (13) during the charging operation.
[00082] The present invention is a single ball catch which serves the purpose of ensuring the mechanism is actuated in a travel of 1mm and stays in that position till desired. Also, the same ball is used to hold the feature in a different state using the similar concept.
[00083] It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context.
