Abstract A disconnector 4, and a breaker 5 which is connected and disconnected by a blade 4d of the disconnector are disposed in a closed tank 2 which is filled with dry air. A terminal of a feeder cable 12 is connected to the disconnector 4. The breaker 5 is connected to an insulated bus 16 disposed outside the closed tank 2, via connecting conductors 13 and 15. As a result, the whole size can be reduced, a closed structure can be easily employed, insulating functions of internal apparatuses can be prevented from being impaired even when environmental pollution occurs, influences exerted on the environment can be eliminated, and the reliability can be enhanced.
