<p>PROBLEM TO BE SOLVED: To provide a gas isolated switching device which can reduce overall length of a gas isolated switching device and a line-to-line distance, eliminate mechanism boxes of the operation devices of a disconnection device and a grounding switch, and facilitate maintenance and inspection work. SOLUTION: A gas isolated switching device is provided with a bus-bar, and a bus-bar disconnection unit having a bus-bar disconnection device fitted on the bus-bar, whereas a metallic container for the bus-bar disconnection unit is formed into T shape with a bus for piping 20 and a branch tube 21 crossing the bus for piping 20. In the bus for piping 20, a bus bar 10 is stored, and in the branch tube 21, a bus-bar disconnection device body 11 is stored. At the side face on the opposite side to the branch tube 21 of the bus for piping 20, a case 22 is embedded, which stores the operation device 15 of the bus-bar disconnection device body 11, and gas is blocked by the case 22.</p> |
