PROBLEM TO BE SOLVED: To reduce vibrations of a bus container by suppressing vibrations of the bus container based on an electrostatic force that is generated between a conductor accommodated in the bus container and the bus container in a three-phase batch type gas-insulated bus.SOLUTION: A three-phase batch type gas-insulated bus 1 includes; a bus container 2 which is formed in a cylindrical shape extending along a long axis and in which an insulative gas is encapsulated; and three conductors 3a, 3b and 3c which are disposed within the bus container 2 and extends along the long axis while penetrating between both end portions of the bus container 2 in a long axis direction. The three conductors 3a, 3b and 3c are provided for making a current of one phase flow to each of the conductors, and the three conductors 3a, 3b and 3c are formed in a spiral shape that turns around the long axis. The three conductors 3a, 3b and 3c are formed in the spiral shape that turns in a common direction at a common pitch, and disposed in such a manner that positions in a circumferential direction become different from each other in the same location in the long axis direction.SELECTED DRAWING: Figure 1 |
