<p>PROBLEM TO BE SOLVED: To downsize the overall constitution by scaling down the space inside the device, and also to suppress use of global warming gas. SOLUTION: A metallic tank 9 being charged with insulating gas is provided with a divider which bifurcates in two directions, and conductors 10 and 5 are arranged within the bushings 11 and 4 connected to the ends of the leaders of this divider. A vacuum valve 1 is applied as a breaking part. This vacuum valve 1 is stored in one hand 11 of the bushings. The conductor 10 connects its one end side to the vacuum valve within the bushing 11, as a branching conductor having a fork branching off within the tank, and also connects its other end side to the conductor 5, within the bushing 4 on the side where the vacuum valve is not stored.</p> |
