Abstract:
1. A gas-insulated bus comprising: a current-carrying conductor disposed along an axial direction of a metallic container that is filled with an insulating gas; a shield fitting through which passes the current-carrying conductor and that has a depressed portion formed on a portion of a barrel-shaped outer surface; an insulating support that has a second end thereof fixed in the depressed portion of the shield fitting and has a first end thereof fixed to the metallic container, and that supports the current-carrying conductor via the shield fitting; an internal conductor that is implanted in the second end of the insulating support and that, along with the second end, is positioned in the depressed portion and fixed to the shield fitting; and a contact that is attached to an inner surface of the shield fitting, that is disposed in a space formed on an inside of the shield fitting, and that makes contact with the current-carrying conductor so as to maintain the shield fitting and the current-carrying conductor at the same electric potential, wherein the internal conductor has such a shape that the internal conductor and the shield fitting together form a substantially barrel-like profile.
