<p>The structures of module tanks are simple and the production thereof is easy since the sizes of the module tanks are the same. Therefore even if the apparatus housed in the tank is changed, the same tank can be used. The basic structure of a module is such that the breaker, the isolator with a grounding switch, bus bushings, cable connection bushings, and gas-isolation spacers are all housed and installed. Except for main circuit devices necessary for the circuit structure, the other excluded main circuit devices are short-circuited through short-circuit conductors. The tank opening is not formed in the production or closed with a lid plate. The bus bushings and the cable connection bushings are arranged on the back of the tank. The gas-isolation spacers are arranged on the top and bottom faces of the tank. An arrester can be housed in place of a breaker in an insulating tube housing the main circuit of the breaker.</p> |
