Furthermore, as shown in FIG. 1 or FIG. 3, the two ends of the vacuum chamber 70 are inserted into the fixed electrode-side terminal 7 1 and the movable electrode-side terminal 7 2. 1 and the movable electrode-side terminal 7 2 cover the periphery of the end of the vacuum chamber 2. By constituting in the above-mentioned manner, it can be obtained that the electric field concentration at the end portion of the vacuum chamber 70 which is easily generated due to the joint portion between the ceramic tube and the metal end plate is greatly reduced. > For example, a fixed electric support body is used to open the air-tight state of the body, and the opening and closing mechanism of the empty chamber is a pole-side end of the substrate surrounded by the body, and then the mechanism; It is a pair of vacuum circuit breakers that extend a part of the circuit breaker in front of it, and is mounted on the substrate of the container wall of the interconnecting feature described above, and is provided on the front pole terminal and An operating link mechanism that supports the two terminal portions on the substrate to operate the movable electrode side end by the movable electrical support is worn through the insulating support. Therefore, the vacuum space can be insulated. The container wall is insulated and supported by the aforementioned substrate operating mechanism, so that: the aforementioned operation is insulated and can be retracted into a body; # the vacuum of the insulation and the aforementioned true connecting rod edge support small and peripheral
