Abstract:
1. A power switchgear comprising: a cylindrical fixed-side conductor; a cylindrical movable-side conductor that has an axis line aligned with an axis line of the fixed-side conductor and that is arranged to face the fixed-side conductor at a predetermined distance; a plurality of cylindrical fixed-side connection conductors that are attached to the fixed-side conductor on a side of the movable-side conductor, and that have each axis line parallel to the axis line of the fixed-side conductor; a plurality of cylindrical movable-side connection conductors that are attached to the movable-side conductor on a side of the fixed-side conductor, have each axis line parallel to the axis line of the movable-side conductor, and that are arranged at positions facing the fixed-side connection conductors; cylindrical fixed-side fixed contacts that are connected to each of the fixed-side connection conductors, and that are arranged to have axis lines parallel to the axis line of the fixed-side conductor; cylindrical movable-side fixed contacts that are connected to each of the movable-side connection conductors, and that are arranged to have axis lines parallel to the axis line of the movable-side conductor; and movable contacts that are attached to the movable-side conductor to be capable of reciprocating in a direction of the axis line of the movable-side conductor, and that are inserted through each of the movable-side connection conductors, wherein each outermost part of the fixed-side connection conductors, the fixed-side fixed contacts, the movable-side fixed contacts, and the movable-side connection conductors are located outside of each outermost diameter of the fixed-side conductor and the movable-side conductor, as viewed from the axis lines of the fixed-side conductor and the movable-side conductor as a center.
