Description:TECHNICAL FIELD
[0001] The present disclosure relates, in general, auto operation of a circuit breaker, and more specifically, relates to an actuating mechanism with bi-directional interlocking.

BACKGROUND
[0002] An electrical operating mechanism (EOM) is used to drive a molded case circuit breaker (MCCB) from a remote location through electrical input. EOM can be of two main types, direct drive operator and stored energy operator. In the case of the stored energy operator, the motor energy is used in the direction of ON-OFF movement, which means the 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. In the case of a direct drive motor operator, motor energy is used in both the opening and closing of the MCCB contacts. The motor operator has three modes of operation, manual, auto and lock mode. In manual mode of operation, the handle is rotated counterclockwise or clockwise to switch ON/OFF the MCCB respectively. In an auto mode of operation, a motor is used to drive a gear train to operate the MCCB unit from OFF to ON and the motor reverses its direction to operate the unit from ON to OFF. The motor operator faces an impact at the end of motor operation which occurs due to solid stoppage from the MCCB and jamming occurs as the direct linkage of mechanical elements from the motor is undergoing through the momentum of the motor. This can cause a deteriorating effect on the gears used in the whole system.
[0003] Therefore, it is desired to overcome the drawbacks, shortcomings, and limitations associated with existing solutions, and develop an improved electrical operation system of direct drive type for the molded case circuit breakers that is capable of reducing the impact of momentum at the end of completion of the operation.

[0020] The present disclosure relates, in general, to auto operation of a circuit breaker, and more specifically, relates to an actuating mechanism with bi-directional interlocking. The proposed mechanism disclosed in the present disclosure overcomes the drawbacks, shortcomings, and limitations associated with the conventional mechanism by providing bi-directional interlocking actuating mechanism having a double ratchet arrangement for securely holding the planetary gears, the mechanism effectively prevents damage caused by the excess momentum of the motor in both directions of motor rotation.
[0021] In the disclosed mechanism, when the MCCB is switched ON, the cam profile on the internal gear facilitates the opening of the first pawl latch, contributing to the disengagement of motion to the internal gear. Similarly, when the MCCB is switched OFF, the cam profile on the internal gear opens second pawl latch, aiding in the disengagement of motion to the internal gear. Additionally, the incorporation of a double ratchet arrangement for holding the planetary gears serves to prevent damage caused by the excess momentum of the motor in both directions of motor rotation.
[0022] The actuating mechanism for MCCB includes a pair of solenoid assemblies including a first solenoid assembly and a second solenoid assembly, actuated concurrently with a motor to operate an epicyclic gear train of the MCCB, wherein the motor rotates clockwise and counterclockwise to activate and deactivate the MCCB.

[0025] In another aspect, the first solenoid plunger and the second solenoid plunger are accommodated on top of the corresponding solenoid assemblies. The epicyclic gear train having bidirectional interlocking using the first and second ratchets with teeth facing in opposite directions. The first solenoid assembly is actuated concurrently with the motor in response to deactivating the MCCB, causing the first C-clamp, connected to the first solenoid plunger, to engage with the first pawl latch and induce clockwise rotation, thereby restraining the motion of the first ratchet.
[0026] The first pawl latch, upon deactivation of the MCCB, returns to the original position aided by the first torsion spring, and the cam profile on the internal gear releases the first pawl latch at the end of motor operation, enabling free rotation of the first ratchet and preventing transmission of motion from the motor gear to the internal gear. The second solenoid assembly is actuated in conjunction with the motor, in response to activating the MCCB, causing the second C-clamp, connected to the second solenoid plunger, to engage with the second pawl latch and induce counterclockwise, thereby restraining the motion of the second ratchet. Upon completion of the operation, the cam profile on the internal gear releases the second pawl latch, the second solenoid assembly deactivates, and the second pawl latch returns to the original position aided by the second torsion spring, enabling free rotation of the second ratchet. The present disclosure can be described in enabling detail in the following examples, which may represent more than one embodiment of the present disclosure.
[0027] The advantages achieved by the mechanism of the present disclosure can be clear from the embodiments provided herein. The double ratchet arrangement effectively prevents damage stemming from excess motor momentum in both clockwise and counterclockwise directions, ensuring the longevity and dependability of the actuating mechanism. Additionally, the bi-directional interlocking enhances safety by securing planetary gears, thereby minimizing the risk of mechanical failures or malfunctions during operation. The cam profile on the internal gear further improves operational efficiency by facilitating the disengagement of residual loading, releasing any remaining mechanical stress after the completion of an operation.

[0029] FIG. 1A illustrates an exemplary view of a bi-directional interlocking actuating mechanism, in accordance with an embodiment of the present disclosure.
[0030] Referring to FIG. 1A bi-directional interlocking actuating mechanism 100 (also referred to as actuating mechanism 100, herein) with an epicyclic gear train 112, double latching, and a cam arrangement for disengaging residual loading, improving operational efficiency in mechanical systems is disclosed. The actuating mechanism 100 can include a pair of solenoid assemblies that can include a first solenoid assembly 102-1, a second solenoid assembly 102-2, a first C-clamp 104-1, a second C-clamp 104-2, a first torsion spring 106-1, a second torsion spring 106-2, a first pawl latch 108-1, a second pawl latch 108-2, a first solenoid plunger 110-1, a second solenoid plunger 110-2 and the epicyclic gear train 112.
[0031] In an embodiment, the electrically operated mechanism can include a motor, a gear train and rack which operates the MCCB. The motor rotates clockwise and counterclockwise for switching ON and OFF the MCCB respectively. Rotation of the motor gear facilitates the rotation of the epicyclic gear train 112 depicted in FIG. 1B which can include a first ratchet 114-1, a second ratchet 114-2, an internal gear 116, a sun gear 118, planetary gears 120 and cam profile 122 on internal gear.
[0032] The first ratchet 114-1 and the second ratchet 114-2 secure the planetary gears 120 in the disclosed mechanism. The motion from motor gear gets transmitted to the sun gear and when the rotation of first rachet 114-1 is restricted, the motion gets transmitted to the planetary gears 120 which then transmits the motion to the internal gear 116. When the ratchets (114-1, 114-2) are free to rotate, the motion from planetary gears 120 does not get transferred to the internal gear 116. The rotation of rachets (114-1, 114-2) is restricted by using pawl latches (108-1, 108-2) which are connected to corresponding solenoid plungers (110-1, 110-2).
[0033] The actuating mechanism 100 for the MCCB can include the first solenoid assembly 102-1 and the second solenoid assembly 102-2, actuated concurrently with the motor to operate the epicyclic gear train 112 of the MCCB, wherein the motor rotates clockwise and counterclockwise to activate and deactivate the MCCB.
[0034] In an embodiment, the first pawl latch 108-1 coupled to the first ratchet 114-1 of the epicyclic gear train 112 to restrain the motion of the first ratchet 114-1 upon deactivation of the MCCB. The second pawl latch 108-2 coupled to the second ratchet 114-2 of the epicyclic gear train 112 to restrain the motion of the second ratchet 114-2 upon activation of the MCCB. The first C-clamp 104-1 coupled to the first solenoid plunger 110-1 to engage with the first pawl latch 108-1 upon the deactivation of the MCCB. The second C-clamp 104-2 coupled to the second solenoid plunger 110-2 to engage with the second pawl latch 108-2 upon the activation of the MCCB. The first torsion spring 106-1 coupled to the first pawl latch 108-1 to aid in returning the first pawl latch 108-1 to the original position upon completion of the deactivation of the MCCB and the second torsion spring 106-2 coupled to the second pawl latch 108-2 to aid in returning the second pawl latch 108-2 to original position upon completion of the activation of the MCCB. The rotation of the motor facilitates the rotation of the epicyclic gear train 112, the epicyclic gear train defining the cam profile 122 accommodated on the internal gear 116 to selectively release corresponding pawl latches (108-1, 108-2) at specific points during the operation of the motor, and wherein the actuating mechanism prevents damage caused due to excess momentum of the motor in both directions of motor rotation.
[0035] The epicyclic gear train 112 can include the planetary gear 120 e.g., three planetary gears that are secured between the first ratchet 114-1 and the second ratchet 114-2, whereupon restriction of the rotation of the corresponding ratchets (114-1, 114-2), the motion is transferred to the planetary gears 120, subsequently transmitting the motion to the internal gear 116 and conversely, upon the rotation of the corresponding ratchets (114-1, 114-2), the motion from the planetary gears 120 is restricted to the internal gear 116. The epicyclic gear train 112 can include the sun gear 118 for rotational power within the epicyclic gear train, where the motion from a motor gear is transmitted to the sun gear 118.
[0036] Further, the cam profile 122 releases the first pawl latch 108-1 upon deactivating the MCCB, allowing unimpeded rotation of the first ratchet 114-1. The cam profile 122 releases the second pawl latch 108-2 upon activating the MCCB, allowing unimpeded rotation of the second ratchet 114-2. The first solenoid plunger 110-1 and the second solenoid plunger 110-2 are accommodated on top of the corresponding solenoid assemblies (102-1, 102-2). The epicyclic gear train 112 having bi-directional interlocking using the first and second ratchets (114-1, 114-2) with teeth facing in opposite directions.
[0037] In another embodiment, the first solenoid assembly 102-1 is actuated concurrently with the motor in response to deactivating the MCCB, causing the first C-clamp 104-1, connected to the first solenoid plunger 110-1, to engage with the first pawl latch 108-1 and induce clockwise rotation, thereby restraining the motion of the first ratchet 114-1. The first pawl latch 108-1, upon deactivation of the MCCB, returns to the original position aided by the first torsion spring 106-1, and the cam profile 122 on the internal gear 116 releases the first pawl latch 108-1 at the end of motor operation, enabling free rotation of the first ratchet 114-1 and preventing transmission of motion from the motor gear to the internal gear 116.
[0038] In another embodiment, the second solenoid assembly 102-2 is actuated in conjunction with the motor, in response to activating the MCCB, causing the second C-clamp 104-2, connected to the second solenoid plunger 110-2, to engage with the second pawl latch 108-2 and induce counterclockwise, thereby restraining the motion of the second ratchet 114-2. Upon completion of the operation, the cam profile on the internal gear 116 releases the second pawl latch 108-2, the second solenoid assembly 102-2 deactivates, and the second pawl latch 108-2 returns to the original position aided by the second torsion spring 106-2, enabling free rotation of the second ratchet 114-2.
[0039] In an implementation, the MCCB protects the circuit from overloads or short circuits. In this case, the mechanism described is applied to control the motor-driven operation of the MCCB.
Turning OFF MCCB
[0040] In response to turning the MCCB OFF, first solenoid assembly 102-1 is actuated concurrently with the motor, causing the first C-clamp 104-1, connected to first solenoid plunger 110-1, to impact the first pawl latch 108-1 and induce clockwise rotation, thereby restraining the motion of the first rachet 114-1. Upon deactivation of the first solenoid assembly, first pawl latch 108-1 returns to its original position aided by the first torsion spring 106-1. The cam profile 122 on the internal gear releases the first pawl latch 108-1 at the end of motor operation, enabling free rotation of first rachet 114-1 and preventing transmission of motion from the motor gear to the internal gear 116, thereby averting damage to the interconnected mechanism due to excess motor momentum.
Turning ON MCCB
[0041] When the MCCB is turned ON, the motor reverses its direction, and second solenoid assembly 102-2 is actuated in conjunction with the motor. The second C-clamp 104-2, connected to the second solenoid plunger 110-2, impacts the second pawl latch 108-2, inducing counterclockwise rotation that restricts the rotation of the second rachet 114-2. Upon completion of the operation, the cam profile on the internal gear disengages the second pawl latch 108-2, second solenoid assembly 102-2 deactivates, and the second pawl latch 108-2 returns to its original position aided by the second torsion spring 106-2, enabling free rotation of second rachet 114-2. This mechanism reduces damage caused by the impact of excess motor momentum in the reverse direction. Bi-directional interlocking of the epicyclic gear train is accomplished using double ratchets with teeth facing in opposite directions.
[0042] Thus, the present invention overcomes the drawbacks, shortcomings, and limitations associated with existing solutions, and provides a double ratchet arrangement that effectively prevents damage stemming from excess motor momentum in both clockwise and counterclockwise directions, ensuring the longevity and dependability of the actuating mechanism. Additionally, the bi-directional interlocking enhances safety by securing planetary gears, thereby minimizing the risk of mechanical failures or malfunctions during operation. The cam profile on the internal gear further improves operational efficiency by facilitating the disengagement of residual loading, releasing any remaining mechanical stress after the completion of an operation. Controlled engagement and disengagement of pawl latches, coupled with torsion springs, contribute to a reduction in wear and tear on critical components, extending the overall lifespan of the mechanism.
[0043] The gear train, involving the sun gear, planetary gears, and internal gear, ensures smooth transmission of motion during both the ON and OFF operations of the molded case circuit breaker. The bi-directional interlocking design provides flexibility, allowing the actuating mechanism to handle motor operations in both clockwise and counterclockwise directions, catering to various operational scenarios. The reliable engagement of the cam profile with the pawl latches ensures precise control over motion transmission, preventing undesired movements and potential damage. Moreover, the solenoid assemblies are activated in a controlled manner, synchronized with motor operation, ensuring proper engagement and disengagement of pawl latches for seamless functionality.
[0044] It will be apparent to those skilled in the art that the mechanism 100 of the disclosure may be provided using some or all of the mentioned features and components without departing from the scope of the present disclosure. While various embodiments of the present disclosure have been illustrated and described herein, it will be clear that the disclosure is not limited to these embodiments only.
