Abstract:
A remote control system for operating a circuit breaker and racking the circuit breaker into and out of electric contact with switchgear contained in a cell cabinet, wherein the circuit breaker is movable by a racking mechanism between racked-in and racked-out positions, the racking mechanism having a driven shaft and the circuit breaker having a plug which is electrically connected to a receptacle provided on the switchgear when the circuit breaker is in the racked-in position to provide power for operation of circuit breaker functions, said remote control system comprising:a) a portable drive motor for mounting in the cell cabinet and having a drive shaft which aligns with the driven shaft of the racking mechanism; b) a lever mounted in said cell cabinet for movement from a disconnected position to a connected position wherein the driven shaft of the racking mechanism is coupled to the drive shaft of said drive motor, said lever having a latch key; c) a latching solenoid for engaging the latch key of said lever to hold said lever in the connected position; d) an electrical connector mounted to extend through the cell cabinet; e) a remote control device connected by an elongated cable to said electrical connector; and f) transfer means electrically connected to transfer operational control of said drive motor, said latching solenoid, and the opening, closing and charging of the circuit-breaker through said electrical connector to said remote control device.
