| description | A gas-insulated switchgear apparatus comprises a set of gas-insulated circuit breakers (l) for three phases juxtaposed on a first horizontal plane, first phase-separated main buses (24) respectively confronting one end of the set of gas-insulated circuit breakers (l) and arranged on second horizontal planes of different levels which are orthogonal to the first horizontal plane, second phase-separated main buses (25) respectively confronting the one end of the set of gas-insulated circuit breakers (l) and arranged on third horizontal planes of different levels which are orthogonal to the first horizontal plane, and a coupling bus (5) and breakers (7, 9) for connecting each gas-insulated circuit breaker (l) to each first phase-separated main bus (24) and each second phase-separated main bus (25) for the same phase. The coupling buses (5) for respective phases have the same length, the breakers (7) for respective phases provided for the first phase-separated main buses (24) lie on a common vertical plane, the breakers (9) for respective phases provided for the second phase-separated main buses (25) lie on another common vertical plane, the first phase-separated main buses (24) for three phases close to the set of gas-insulated circuit breakers (l) are respectively arranged on upper installation planes of different levels above the breakers (7), and the second phase-separated main buses (25) for three phases remote from the set of gas-insulated circuit breakers (l) are respectively arranged on lower installation planes of different levels below the breakers (9). This construction can reduce the overall size of the gas-insulated switchgear apparatus of phase-separated type to simplify the production thereof and permits easy maintenance inspection. |
