GAS-INSULATED SWITCH DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce the installation space of a gas-insulated switch device, in the gas-insulated switch device which includes a T-type branching bus disposed in a T-type branching portion. SOLUTION: This gas-insulated switch device is related to the one wherein two disconnector-grounded switch devices are disposed in series with each other to connect a branching disconnector with the connective point of the two disconnector-grounded switch devices. This devices characterized in that two disconnector-grounded switch devices (4a, 6a; 4b, 6b) are stored in a first grounded metallic container 1, and a branching disconnector 4c is stored in a second metallic container 2 branched and connected from the metallic container 1.
