ABSTRACT:
A gas isolated disconnecting switch is provided which performs a sufficient restriking surge suppressing function, induces no adverse effect on the operation of a circuit breaker disposed within the system and always enables the circuit breaker to surely interrupt a fault current. Under the closed condition of the gas isolated disconnecting switch, a main stationary member 6 engages with a main movable member 16 and an auxiliary movable member 17 with an auxiliary stationary member 8 respectively. Accordingly the portion of an auxiliary conductor 7 which passes through a cylindrical magnetic body 9 is short-circuited via the main stationary member 6 and the main movable member 16, and no influence is induced on the operation of the circuit breaker disposed in the system. During the opening operation of the disconnecting switch, the auxiliary movable member 17 disengages with a time delay. At this moment, the current flows through the portion of the auxiliary conductor 7 which passes through the cylindrical magnetic body 9 to thereby perform a sufficient restriking surge suppressing function.
