摘要： In a vacuum interrupter comprising a disc-shaped stationary electrode and a disc-shaped movable electrode arranged in an evacuated envelope in opposed relationship, a slot or a salient part is formed on the surface of both the electrodes and thereby a path of an arc current in disconnection operation of both the electrodes is formed along the circumference of the disc-shaped electrode. The shape and position of the slot is selected so that the arc current flows uniformly along the entire circumference of both the electrodes.
