Switchgear operating mechanism |
摘要 |
A switchgear operating mechanism is disclosed which includes two helical springs which are stretched to store energy to close and then open circuit breaker contacts. A mechanism is provided for stretching the springs in response to reciprocating movement of a hook stick. 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. The handle is preferably operable by a shot gun type hook stick.
