A bus container, its assembling method and a gas-insulated switchgear, in which gas treating working in a factory and at a site is reduced, an operation is made simple, and a process is shortened. In the case of connection of a container (101) and a container (102), a conductor (103) of spherical shape is kept in contact with and fixed to a contact (102f), the container (101) is caused to approach to the container (102), the conductor (103) is joined to a contact (101f). Before connection, a valve (108) is tightly contacted with a center conductor (102e) by the force of a spring (109), however, as the container (101) and the container (102) are approached, the tip of the valve (108) is brought into contact with the center conductor (101e), the spring is compressed, the valve (108) and the center conductor are separated, an insulating gas of high pressure in the container (102) presses the air existing in the connection portion (107) out of the container through a opening hole formed in the center conductor (102e) before flanges (101a) and (102a) are connected, and the connection portion is filled with the insulating gas. |
