ABSTRACT:
A gas-insulated switching apparatus comprises gas-insulated interrupters, gas-insulated buses and gas-insulated disconnecting switches, whereby the movable electrode side terminals of all the disconnecting switches accommodated in the apparatus are so arranged as to be connected to gas-insulated interrupters to be disconnected from a power source, i.e., to a load line side to be interrupted by the disconnectors.
