PROBLEM TO BE SOLVED: To reduce work amount to be performed at a factory and a job site, and to narrow the installation space. SOLUTION: These are provided grounded tanks 2a, 2b, 2c for individual phases, where main circuits are housed, bushings 6a, 6b, 6c fitted to the grounded tanks for individual phases respectively and connected electrically to the outside along with the main circuits housed inside the grounded tanks, manipulation device boxes 24 for housing manipulation mechanism portions for driving the main circuit contacts which are inside the grounded tanks for individual phases respectively, a controller box 27 for electrically controlling the operation of the manipulation mechanism portions for individual phases, and a frame 21 for supporting these. The grounded tanks 2a, 2b, 2c for individual phases to which the bushings are fitted, the device boxes 24 in which the manipulating mechanism portions for individual phases are housed, and the controller box 27 are put on a base 23 and are united into a body, and this is supported by the frame. |
