VACUUM CIRCUIT BREAKER AND GAS INSULATED SWITCHGEAR USING THE SAME |
摘要 |
Provided is a vacuum circuit breaker whose insulation cylinder contained in a gas-insulated-switchgear housing contains a vacuum valve and which can be downsized while the cylinder's required mechanical strength is retained, and a gas-insulated switchgear using the same is also provided. The vacuum circuit breaker includes a plurality of insulation cases 10 that are arranged parallel to each other in a container filled with an insulating gas, and each of the plurality of insulation cases 10 includes a first insulation frame 11a in which a section orthogonal to its longitudinal direction is in a substantial square-bracket shape, a second insulation frame 11b in which a section orthogonal to its longitudinal direction is in a substantial square-bracket shape and which is arranged with a gap from the first insulation frame 11a in a manner that open sides of the substantially square-bracket shaped frames oppose to each other, and a vacuum valve 14 that contains attachable and detachable electrodes and is housed in each of the plurality of insulation cases 10. |
