<P>PROBLEM TO BE SOLVED: To provide a gas insulation bus capable of minimizing a conductor diameter by reducing a bolt pull-out load by an electromagnetic force generated by a short-time resistant current. <P>SOLUTION: A gas insulation bus has: a tubular tank 1 which is filled with an insulation gas G and has openings 1a, 1b, 1c in a length direction and a direction orthogonal to the length direction, respectively; a length-direction conductor 7 disposed in the length direction inside the tank 1; a diameter-direction conductor 5A connected to the length-direction conductor 7 and disposed to be orthogonal to the length-direction conductor 7; and insulation spacers 2<SB POS="POST">1</SB>, 2<SB POS="POST">2</SB>, 2<SB POS="POST">3</SB>for fixing the length-direction conductor 7 and the diameter-direction conductor 5A at the openings 1a, 1b, 1c of the tank 1, respectively. In the gas insulation bus, a connecting part 9 for both the conductors is disposed at an intersection B of a center axis CL<SB POS="POST">1</SB>of the length-direction conductor 7 and a center axis CL<SB POS="POST">2</SB>of the diameter-direction conductor 5A. <P>COPYRIGHT: (C)2012,JPO&INPIT |
