However, as shown in FIG.
In the conventional gas-insulated switch 9 as shown in FIG. 1, first, second and third branch pipes are provided in parallel on the upper part of the grounded metal container 1, and the disconnector 3 and the ground switch are respectively provided in these branch pipes. Since the drive mechanism for the vessels 4 and 5 is arranged, the container 1
There was a drawback that the whole thing became huge. That is, if the insulation distance of each component, such as the linear distance L5 between the fixed contact portions, is secured, there is a limit to the reduction of the diameter of each branch pipe 100, 101, 102. If they are arranged side by side on the upper part of the container 1, the distances L1 and L2 of their center points become long in order to prevent the branch pipes from contacting each other. As a result, the total length L3 of the gas-insulated switch 9 becomes large, which inevitably causes the total length L4 of the gas-insulated switchgear shown in FIG. 12 to become large. Therefore, in the conventional gas insulated switchgear, there is much room for improvement in downsizing of the entire gas insulated switchgear.
