<p>PROBLEM TO BE SOLVED: To eliminate the need for unloading and sealing a gas when attaching or detaching a bus at a power supply side and a power cable at a load side in a gas insulation switching device. SOLUTION: A gas insulation switching device consists of a cable head 3 that is connected to a cable 1, a load-side cable connection part 10 that is connected to the cable head 3, a power supply side connection part 9 that is connected to the load-side cable connection part 10, and a bus 5 that is connected to the power supply side connection part 9. Also, the device has a movable side pipeline 13 that is supported by a trestle 14, a pipeline edge part 6A where the movable side pipeline 13 is inserted so that it slides inside, bellows 12 that are contracted with the movement of the trestle 14 provided between the trestle 14 and the pipeline edge part 6A, an O ring 11 made of a sealing member being inserted between the movable side pipeline 13 and a pipeline 6, and a cable head 3 where an edge part is connected by the trestle 14.</p> |
