摘要： PROBLEM TO BE SOLVED: To attain a compact and inexpensive structure which permits replacement to be performed simply and easily for each of broken contacts and which is applicable to uses of bus-bar selection. SOLUTION: Insulation gas is filled in an insulated porcelain tube. A plurality of switchgear devices formed with the contact consisting of a fixed electrode and a movable electrode are respectively mounted on the outer surface of a metal container 49. The compound switchgear devices 30a to 30bc for three phases of a structure where the metal container is supported by a supporting porcelain tube 50, are mounted on a frame 41 at equal spaces. An upper connection mechanism 48 connected to the movable electrode of the contact introduced from each of the switchgear device is provided in the metal container. One end of each of insulated operation rods 51 to 53 provided by passing the upper connection mechanism through the supported porcelain tube. Each of the other ends is jointed to a lower joint mechanism mounted on the frame. The operating effort of an operation mechanism 57 mounted on the frame is transmitted from the lower connection mechanism to the movable electrode through the insulated operation rod and the upper connection mechanism, thus permitting each contact of the switchgear device to be switched, independently.
