摘要： A tank type vacuum circuit breaker uses a columnar or cylindrical insulation rod at a connection portion between an operating mechanism unit and a vacuum valve. The insulation rod is connected to the operating mechanism unit and the vacuum valve by rod-shaped pins. To prevent the insulation rod itself from falling, connection is made by shifting phases of the pins 90 degrees, respectively, each pin being connected to the operating mechanism unit and the vacuum valve. Accordingly, the falling of the insulation rod, the use of an insulation support tube and an insulation support for ensuring mechanical strength, are avoided. Further fastening of those supports by bolts or the like is not needed. Increases in the number of components, the size of the shape of assembly members around the insulation rod, and weight due to such increases, are prevented.

摘要： A gas insulated switchgear includes a vacuum interrupter having a movable contact and a fixed contact in vacuum. The movable contact is on one side of a movable conductor that passes through a bellows. An insulating rod is coupled to the other side of the movable conductor that passes through the bellows. The insulating rod and the other side of the movable conductor are placed in an insulator. The vacuum interrupter, the insulating rod, and the insulator are disposed in a gas tank. An operating mechanism is disposed on a movable side end portion of the gas tank and connected to the insulating rod. An inner circumferential side space of the bellows, an internal space of the insulator, and an internal space of the operating box are in communication with each other; and pressure in these spaces is lower than pressure in the gas tank.
