<p>PROBLEM TO BE SOLVED: To obtain a gas-insulated switchgear which reduces the size in the length direction of a container by a method wherein the container is formed of a third wall face and a fourth wall face which are connected to each other in such a way that they are faced at a second distance which is larger than a first distance and which can take the insulating distance between conductors and the conductors are arranged sequentially to the side of the fourth wall face from the side of the third wall face. SOLUTION: A branch pipe 13 is formed to be an oval shape in such a way that respective wall faces 20a, 20b which are faced at a first distance to obtain the required insulating distance between conductors 17 and the branch pipe 13 are connected to respective arc-shaped wall faces 21a, 21b which are faced at a second distance larger than the first distance between the respective wall faces 20a, 20b so as to obtain the insulating distance between the respective conductors 17 and which protrude to the outside. Then, the respective conductors 17 are arranged sequentially from the side of the wall face 21a to the side of the wall face 21b. Thereby, the conductors 17, for a three-phase portion, which are connected to an electric apparatus, for a three-phase portion, which is housed in a container can be derived from the branch pipe 13, and the size in the length direction of the container can be reduced.</p> |
