BUS CONNECTING CONSTRUCTION

摘要

PROBLEM TO BE SOLVED: To facilitate bus connection between fixed electrodes of a plurality of phases, by taking out one of leader buses connected to fixed electrodes of a plurality of phases from one side and the remaining leader buses from one side of junction terminal strips. SOLUTION: Movable electrodes which turn and move between a fixed electrode 5 and grounding electrode arranged correspondingly within a vacuum ground container are provided, and further first to third circuit switch gears are arranged. Next, 9 pieces of fixed electrodes 5 are fixed to a junction terminal strip 27, and each leader bus 8 is connected to each fixed electrode 5. Here, leader buses 8 of the first circuit switch gear to second and third circuit switch gears are arranged sequentially from the left side toward the right side of the junction terminal strip 27. In this arrangement, the leader bus 8 of each switch gear laps 1 phase 1X, 2X and 3X to one side of the junction terminal strip 27 and laps 2 phase 2X to 2Z and 3 phase 3X to 3Z to other side. By doing this, a careless omission of connection between the leader bus 8 and the fixed electrode 5 can be prevented during connection.
