Abstract
A gas-insulated switching apparatus is disclosed which includes a circuit breaker having a breaking section with at least a couple of mutually detachable contacts and a grounded tank containing the breaking section and filled with an insulating gas, the grounded tank being maintained at earth potential. A first bushing is vertically mounted on one side of the grounded tank, the central conductor of the first bushing being connected with one of the contact of the breaking section. A disconnecting switch has insulating gas sealed in it and accommodates a disconnecting section in a tank which is arranged connected to but gas-partitioned from the circuit breaker in an axially extending region of the grounded tank on the other side of the region where the first bushing is mounted. A bushing support tank has insulating gas sealed in it and is arranged so that is connected to but gas-partitioned from the disconnecting switch in an axially extending region of the grounded tank on the side of the disconnecting switch which is opposite to that of the circuit breaker. A second bushing is vertically mounted on the bushing support tank and a grounded switch is arranged inside the bushing support tank in a region which is an axially extending region of the circuit breaker. A lightning arrester is arranged gas-partitioned from the bushing support tank below the axis of the circuit breaker and the disconnecting switch but in the direction of this axis. The lightning arrester is electrically connected to the central conductor of the second bushing inside the bushing support tank.
