<p>PROBLEM TO BE SOLVED: To provide a gas insulation switching device, which does not require for increasing an installation area, and which can restrain initial investment, and cope flexibly, regardless of the use of a crossing and retracting method. SOLUTION: When a crossing and retracting method is used for transmission line circuits 110, 120, connection bus-bars 71 to 74, for connecting a line circuit 210 and a bushing 121, and connection bus-bars 81 to 84 for connecting a line circuit 220 and a bushing 111 are pulled around the outside of an iron groove 23 to cross them each other. Therefore, the distance between the line circuits 210, 220 and the bushing 111, 121 is kept, so as to be short, regardless of the use of the crossing and retracting method. It is thus necessary only to increase the number of connection bus-bars and change the layout of the bushing 111, 122 parts in making a change from the arrangement of no use of the crossing and retracting method to that of its use.</p> |
