Claims

[Claim for Utility Model Registration] An airtight metal container is filled with an insulating gas and houses a gas circuit breaker, the gas circuit breaker having a fixed base and a movable base separated from each other, In a gas-insulated switchgear consisting of an opening/closing part provided between a fixed side base and a movable side base and an insulating cylinder surrounding the opening/closing part, a working hole is formed on the outer circumferential surface of the insulating cylinder body and the hole is plugged. A gas insulated switchgear characterized in that an insulating tube is formed by providing an insulating cover that can be opened and closed.
