Description:TECHNICAL FIELD
[0001] The present disclosure relates, in general, to the field of auto operation of circuit breakers, and more specifically, relates to a door interlock feature for an actuating mechanism for the circuit breaker.

BACKGROUND
[0002] An electrical operating mechanism (EOM) is used to drive 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 direct drive operator, motor energy is used in both ways of closing and opening the MCCB. 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. Stored energy operator has two modes of operation that are manual and automated. Manual mode consists of a charging unit and the handle attached to it, so the cranking system provided onto the handle allows the customer to drive the MCCB from ON-OFF and a manual ON button allows the unit to discharge the energized spring through various linkages mechanically connected. The auto mode consists of a motor charging the spring and driving the unit from ON-OFF and input from a remote location discharges the energized spring through mechanical linkages connected below. MCCB being the governing element, with preset boundary conditions and constraints, stored energy electrical operating mechanism (SE-EOM) must perform primary, secondary, and tertiary functions in a determined manner.
[0003] However, the present SE-EOM lacks a feature that can be used as an interlock to allow the panel door to be locked when the MCCB is in the ON state. Also, the panel door should be accessible when the MCCB is in the OFF state. This ensures the safety of the personnel operating the electrical equipment and prevents the personnel from accessing the equipment from inside the panel door when the MCCB is in ON condition which can create a possibility of an electrical hazard.
[0004] There is, therefore, a need for an added feature inside the SE-EOM mechanism to accomplish this safety interlock for safety purposes. Also, the feature needs an interlock defeat mechanism that can only be accessed by an approved person in case the panel door needs to be opened while MCCB is in ON condition for any checking or observation purpose

[0033] FIG. 1A and FIG. 1B illustrates an exemplary on and off state of actuating mechanism of the circuit breaker, in accordance with an embodiment of the present disclosure.
[0034] The actuating mechanism 100 of the circuit breaker 122 includes door interlock assembly that includes a first door interlock component 102-1, a second door lock component 102-2, a left hand side (LHS) plate 104, one or more guiding pins 106 (also referred to as guiding pins 106, herein), one or more springs (108, 110), rack front pin 112, rack assembly 114, knob 116, panel door 118, motor operator 120, circuit breaker 122, ball catch mechanism 124, and motor operator (MO) cover 126. The one or more springs can include interlock main spring 108 and upper spring 110.
[0035] The LHS plate104 serves as the left-hand side support structure. It provides a stable platform for assembling the first and second door interlock components (102-1, 102-2). The first door interlock component 102-1 and the second door interlock component 102-2 operate together to prevent the opening of the panel door 118 when the circuit breaker 122 is in an active state. The LHS plate 104 on which the first and second door interlock components (102-1, 102-2) are assembled with the help of guiding pins 106, interlock main spring 108 and upper spring 110. The rack front pin 112 is assembled with the rack assembly 114 which guides the first door interlock component 102-1.
[0036] The guiding pins 106 are accommodated in corresponding holes in the first door interlock component 102-1 and the second door lock component 102-2, thereby securing and positioning the first door interlock component 102-1 and the second door lock component 102-2 on the LHS plate 104. They ensure proper alignment and functionality. The interlock main spring 108 provides the necessary tension and force to ensure the effective operation of the actuating mechanism. It contributes to the return and engagement of the interlock components. The upper spring 110 plays a crucial role in providing tension and aiding in the proper functioning of the actuating mechanism.
[0037] The rack front pin 112 as an integral part of the rack assembly 114, the rack front pin 112 being accommodated in corresponding holes in the LHS plate 104, where the rack front pin 112 engages with the rack assembly 114 to guide the linear movement of the first door interlock component 102-1 and the second door interlock component 102-2. The rack assembly 114 configured to move linearly corresponding to the rotation of a drive shaft. The drive shaft operatively coupled to an epicyclic gear assembly, such that the rotation of the epicyclic gear assembly facilitates the rotation of the drive shaft, where the epicyclic gear assembly operatively configured with a motor shaft of a motor 120, the rotation of the motor shaft facilitates the rotation of the epicyclic gear assembly.
[0038] The rack assembly 114 configured to reach the first position shown in FIG. 1A, causing the second door interlock component 102-2 to move with it, thereby preventing the panel door 118 from opening in the ON/TRIP state of the circuit breaker 122 and reach the second position shown in FIG. 1B, enabling the second door interlock component 102-2 to return to its original position due to the biasing action of one or more springs, allowing the panel door 118 to open in the OFF state of the circuit breaker 122.
[0039] The actuating mechanism 100 allow the opening of the panel door 118 by incorporating a defeat mechanism through the rotation of the knob 116. Automatically interlocks the panel door 118 in the ON/TRIP state due to an auto-restoration mechanism and disable the door interlock assembly by rotating the knob 116 until the disable position is reached to facilitate maintenance while the circuit breaker is in the ON state.
[0040] In an embodiment, the rack assembly 114, upon reaching the first position shown in FIG. 1A as a result of the movement of the mechanism, induces the rack front pin 112 to displace the door interlock assembly, leading to the overlapping of the second door interlock component 102-2 with the panel door 118 thereby preventing the door from opening during the ON/TRIP state of the circuit breaker 122.
[0041] In another embodiment, in the OFF state of the circuit breaker 122, the rack assembly (114), upon reaching the second position shown in FIG. 1B, undergoes a biasing action from one or more springs, facilitating the return of the door interlock assembly to its original position and thereby opening the panel door 118.
[0042] In another embodiment, the actuating mechanism 100 can include the defeat mechanism allowing access to one or more internal components of the electrical panel while the circuit breaker remains in the ON state. The defeat mechanism configured to rotate the knob 116 until the second door interlock component 102-2 is pushed inward restricts the reverse movement of the first door interlock component 102-1, thereby allowing the second door interlock component 102-2 to smoothly slide over the first door interlock component 102-1, wherein combined action facilitates the unhindered opening of the panel door.
[0043] In another embodiment, the rotation of the knob 116 to the disable position deactivates the interlock mechanism for maintenance tasks while the circuit breaker is in the ON state. The rotation of the knob configured to securely hold the second door interlock component 102-2 in place using a pin of a ball catch mechanism 124 shown in FIG. 5 when the disable position is reached; move, upon activation of the circuit breaker, the first door interlock component (102-1), thereby effectively bypassing the interlock mechanism.
[0044] Thus, the present invention overcomes the drawbacks, shortcomings, and limitations associated with existing solutions, and provides the actuating mechanism designed to effectively secure the door, preventing inadvertent or unauthorized access to the active electrical components housed within the panel. This mechanism not only ensures security but also facilitates authorized personnel to access and safely perform maintenance or inspections on the internal components of the electrical panel. The actuating mechanism is engineered to provide controlled access to the internal components even when the circuit breaker is in the ON state, addressing the need for controlled accessibility during various operational states. Additionally, the mechanism is tailored to meet maintenance requirements, allowing unhindered access to internal components while the MCCB is in the ON state, thus ensuring efficient maintenance tasks.
[0045] FIG. 2A and FIG. 2B illustrate an exemplary prevention of door opening in the MCCB ON state, in accordance with an embodiment of the present disclosure.
[0046] In an embodiment, when the circuit breaker is in ON/TRIP state, the first door interlock component 102-1 and the second door lock component 102-2 serve as a single entity depicted in FIG. 2B. As the rack assembly 114 reaches first position due to the movement of the mechanism, the rack pin 112 may move door interlock assembly and the second door interlock component 102-2 overlap with the panel door 118 which prevents the door opening depicted in FIG. 2A.
[0047] This configuration ensures that attempting to open the panel door 118 while the circuit breaker 122 is in ON/TRIP state may be met with resistance. The actuating mechanism 100 effectively maintains the door in a secured position, preventing inadvertent or unauthorized access to the active electrical components housed within the panel 118. This safety feature serves as a crucial precaution against potential electrical hazards.
[0048] FIG. 3A and FIG. 3B provide an exemplary view illustrating the allowance of door opening in the OFF state of MCCB, in accordance with an embodiment of the present disclosure. When the circuit breaker 122 is in OFF state, as shown in FIG 3B, when the rack reaches the second position depicted in FIG. 1B, the door interlock assembly may return to its original position due to spring biasing action thus allowing the panel door 118 to open. As the rack assembly 114 reaches the second position, as shown in FIG. 1B, the spring exerts a biasing action on the door interlock assembly. This force assists in returning the door interlock assembly to its original position. The panel door 118 is free to open. This enables authorized personnel to access and perform maintenance or inspections on the internal components of the electrical panel safely.
[0049] FIG. 4A and FIG. 4B provide an exemplary view illustrating the allowance of door opening in the ON/TRIP state of MCCB, in accordance with an embodiment of the present disclosure. To access the internal components of the electrical panel while the circuit breaker remains in the ON state. As illustrated in FIG. 4B, the user engages the defeat feature by rotating the knob 116 until the second door interlock component 102-2 is pushed inward. Simultaneously, the rack mechanism prevents first door interlock component 102-1 from moving in the reverse direction. This action allows second door interlock component 102-2 to smoothly slide over first door interlock component 102-1. Consequently, the panel door 118 is unimpeded and can be opened without any hindrance, as depicted in FIG. 4A. The mechanism is the ability to provide controlled access to the internal components of the electrical panel even when circuit breaker 122 is in the ON state.
[0050] As depicted in FIG. 5, the pin of the ball catch mechanism 124 securely holds the second door interlock component 102-2 in place. FIG. 6 illustrates an exemplary view of door interlock assembly, in accordance with an embodiment of the present disclosure. When maintenance tasks require unhindered access to the internal components of the electrical panel while the MCCB is in the ON state. By rotating the knob 116 until the disable position is reached, the interlock assembly is intentionally deactivated. As depicted in FIG. 5, the pin of the ball catch mechanism 124 securely holds the second door interlock component 102-2 in place. In this state, when the MCCB is activated, only the first door interlock component 102-1 moves, effectively bypassing the interlock feature.
[0051] It will be apparent to those skilled in the art that the actuating 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. Numerous modifications, changes, variations, substitutions, and equivalents will be apparent to those skilled in the art, without departing from the spirit and scope of the disclosure, as described in the claims.
