STRUCTURE FOR GROUND OF GAS INSULATED BUS

摘要

PURPOSE: A grounding structure of a gas insulated bus is provided to prevent the generation of an induced voltage and the loss of an enclosure by crossing the shapes of enclosures of a gas insulating bus line and grounding with a grounding lead wire. CONSTITUTION: A first bus line(100) includes three enclosures(110,120,130) and the insulation cases(140,150) of an electrical insulator which has a similar diameter to that of an enclosure between enclosures. The insulation cases electrically insulate the interval of each enclosure. A solid wire(160) supplying power is located in an inside center of the insulation cases and the enclosure. The solid wire is supported by a spacer. A second bus lines(200) and a third bus lines(300) have the same structure as the first bus line. Both ends of a plurality of insulation protection parts respectively is connected to a pair of the enclosures located in the both ends of the insulation cases. The insulation protection part makes a current flowing in a stat of generating a surge.
