SWITCHGEAR OPERATING MECHANISM

摘要

SWITCHGEAR OPERATING MECHANISM A switchgear operating mechanism including helical springs which are stresses to store energy to close and then open circuit breaker contacts. A mechanism is provided for charging the springs in response to reciprocating movement of a charging member. A single operating handle is provided with a spring biased detent arrangement such that the handle may be moved from a predetermined reset position to a closed position to close the circuit breaker contacts using energy from the charged springs. The handle is returned to the reset position by the spring biased detent arrangement and may be moved from that position to an open position to open the circuit breaker contacts using energy from the charged springs.
