Abstract
In a vacuum circuit breaker corresponding to three-phase, which is configured by linearly arranging three pressure tanks respectively corresponding to one-phase, in which insulation gas is encapsulated, and a vacuum valve is installed, each pressure tank has a nearly longitudinal shape or a nearly square shape, viewed from a plane surface, and the vacuum valve is arranged in each of the pressure tanks in a state where a drive direction of the movable conductor is aligned with an upper lower direction, and the movable conductor is positioned lower than the vacuum valve, and keeps a sufficient insulation distance with respect to the movable-side connection conductor, and is neared to a position in one of diagonal directions or longitudinal directions of the pressure tank having a nearly square shape or nearly ellipsoidal shape, and moreover, the operation mechanism is arranged and configured at a position, which is lower than the vacuum valve.
