CONSTITUTION: A gas insulated switch device comprises bus lines, disconnectors, a breaker, a first metallic case(9a) which contains the breaker and is grounded and a second metallic case which contains the plurality of bus line disconnectors, or a plurality of second metallic cases(9b,9c) which contain the plurality of bus line disconnectors in a single gas compartment. The first metallic case and the second metallic case are connected to each other through a gas partition spacer(7a). A plurality of bushings(6a,6b,6c) for leading a bus line are attached to the second metallic case with a preset spreading angle between the adjacent bushings for leading a bus line. |
