<p>The present invention relates to a gas insulated switching device. In the gas insulated switching device, a bus disconnecting switch disposed adjacent to the bus-side support insulator supporting one side of a circuit breaker around the bus contact point on the case, and an outgoing line disconnecting switch disposed adjacent to the outgoing line-side support insulator supporting the other side of the circuit breaker around the load outgoing line contact point on the case are integrated with each other. Also, a disconnecting switch rod for switching the bus disconnecting switch and the outgoing line disconnecting switch is linked to a circuit breaker rod connecting the circuit breaker via a switch to the outside of the case. Here, since the bus disconnecting switch and the outgoing line disconnecting switch are linked to each other with a time delay after the circuit breaker is first switched, a structure in which the disconnecting switch and a ground switch are integrally received around the circuit breaker in the case having a small volume may be provided to implement a light weight switching device of reduced cost.</p> |
