Claims

[Claims for Utility Model Registration] 1. A plurality of individual switches are housed in a sealed case 6, one terminal 10 of the housed switches is connected to a common bus bar 11 inside the case 6, and the switch section is The other terminal 12 is connected to a bushing 14 that penetrates through the case 6, and a trunk cable 15 is connected to the bushing 14, and a door that can be opened and closed is provided on the front side and is installed on the ground above the manhole. In a ground-mounted multi-circuit gas switch which is housed in a cabinet 4, a slip-on type bypass bushing 17 connected to the common bus bar 11 is inserted through the case 6, and the bypass bushing 17 that is inserted therethrough is provided. A high-pressure multi-circuit gas switch characterized in that a cable introduction part 4d for attaching and detaching a bypass cable 24 to and from a bypass bushing 17 is provided on the wall surface of the cabinet 4 on the side opposite to the bypass bushing 17. 2. The bypass bushing 17 is provided on the side surface 6b side of the case 6, and the cable introduction part 4d
is provided on the side surface 4c of the cabinet 4 facing the bypass bushing 17, and the cable introduction part 4d is formed so that a part or the entire side plate of the cabinet 4 can be opened and closed or removed. The high-pressure multi-circuit gas switch according to claim 1. 3. The high-pressure multi-circuit gas switch according to claim 1 or 2, wherein the bypass bushing 17 and the bypass cable 24 are of a load break type capable of switching and closing a load. 4. The high-pressure multi-circuit gas switch according to claim 1 or 2, wherein a bypass switch 40 is interposed in series with the bypass cable 24 connected to the bypass bushing 17.
