Abstract:
The disclosed invention ensures safe operation of an electrical switchgear by preventing an operator from contacting or interacting with an active circuit breaker. One way this is accomplished is through a locking system that prevents a door to the interior of the switchgear from opening until the circuit breaker is in a disengaged position. A second way this is accomplished is by a manipulation restriction system that prevents the circuit breaker from being manually moved unless the door is closed. Another way this is accomplished is by a circuit breaker decoupler, accessible from the exterior of the switchgear that can directly manipulate the circuit breaker into disengagement.
