Abstract:
    To miniaturize a vacuum circuit breaker by improving arrangement of vacuum valves in it and insulation between the vacuum valves as well as between the vacuum valve and a sealed vessel. Vacuum valves, each with three phases, are so arranged, in parallel, that their axial cores represent vertexes of a triangle. Insulating barriers made of insulating material are inserted between the vacuum valves, between the vacuum valve and a sealed vessel, and between other vacuum valve and the sealed vessel, to support the vacuum valves. The insulating barriers are partially overlapped each other at lower part of the vacuum valve while other insulating barriers 31 are partially overlapped each other at a lower part of other vacuum valve.
