THREE-PHASE GAS-INSULATED BUS

摘要

PROBLEM TO BE SOLVED: To provide a gas-insulated bus which can be made compact while taking account of the insulation performance.;SOLUTION: An insulation spacer 5 is composed of a U-shaped insulator 5C, a center conductor 5A held substantially in the center of the U-shaped insulator 5C, and connection metal fittings 5B provided at both ends of the U-shaped insulator 5C. A collector 4 for coupling an electrification conductor 3 is fastened to at least one center conductor 5A. A tank 2 is composed of piping 2A and a flange 2B. An adapter flange 6 is held between the flanges B and coupled thereto. The adapter flange 6 has three swollen parts 6A protruding from the inner peripheral surface of the piping 2A at substantially equal interval, and the insulation spacer 5 is configured to fix both ends of the U-shaped insulator 5C to two adjoining swollen parts 6A.;COPYRIGHT: (C)2014,JPO&INPIT
