摘要： A gas insulated switchgear includes: a center conductor that is arranged to extend horizontally in a tank; a cylindrical member that is arranged in the tank to surround a center conductor, and formed by curving a metal plate-like member into a cylindrical shape and then joining circumferentially opposed both ends of the plate-like member by welding to form a welding portion, the welding portion being located on a lower side of the cylindrical member; and a current transformer for instruments, through which the cylindrical member is inserted, the current transformer being supported by the cylindrical member, and being arranged to surround the center conductor. The welding portion includes a metal spacer sandwiched between the circumferentially opposed both ends of the plate-like member, and the spacer and the ends are welded to each other.

摘要： A fluid-insulated electrical apparatus includes a grounded tank which is an airtight metal vessel filled with an insulating fluid. A conductor to which a high voltage is applied is disposed in the grounded tank. A metal plate that is press-processed to have an inclined portion and a groove between adjacent head top portions is fixed to and electrically connected to an inner wall of the grounded tank.

摘要： A gas-insulated switchgear apparatus includes a center conductor 2, a current transformer 4 surrounding the center conductor 2, an electric field shield 5, and a metallic vessel 1. The electric field shield 5 is located between the center conductor 2 and the current transformer 4 and surrounds the center conductor 2. The current transformer 4 and the electric field shield 5 constitute a tubular part that outputs a signal representing an electric physical quantity. The metallic vessel 1 is filled with an insulating gas 19. The tubular part has an opening 6 formed therein. In a posture in which the center axis of the tubular part about which the tubular part surrounds the center conductor 2 is substantially horizontal, the opening 6 is located in a surface of the tubular part, which surface is included in a lower portion of the tubular part and faces the center conductor 2.
