<p>PURPOSE: To provide a gas-insulated switch device which can shorten the dimension of the axial direction of main bus to miniaturize the whole of a device and reduce an installation area and a building volume, and at the same shorten outage time of an already provided line shortened. CONSTITUTION: A main bus BUS1 is constituted of a T-shaped type conductor 8a having the branching point 7 of a line, and the movable side electrode 9 of a bus-side disconnector DS1 is built in the T-shaped type conductor 8a and one end of the conductor of the main bus direction is fixedly supported to an insulating spacer 10. On the other hand, a contact 18 is provided at the other end of the T-shaped type conductor 8a, and an electric field relaxation shield 19 is mounted thereon, and a lid 20 is provided in the flange 2a of a container 2. The gap between the shield 19 and the lid 20 is provided as electrically required insulating distance. An adjacent line is separated by a distance L1 (pitch between lines) and electrically connected between the main buses through a detachable device DB1 constituted of a datachable container 6 for containing a detachable conductor 21.</p> |
