Claims

[Claims for Utility Model Registration] 1. A fixed electrode with one end installed in the vacuum valve, a movable electrode with one end installed in the vacuum valve so as to be openable/closeable with respect to the one end of the fixed electrode, and the movable electrode. A rod for opening and closing the electrode, a pressure contact spring installed between the front rod and the other end of the movable electrode to press the one end of the movable electrode against the one end of the fixed electrode when the rod is closed, and the rod. A first member installed between the other ends of the movable electrodes to buffer impact force on the movable electrodes when the rod is opened.
and a second metal buffer installed between the other end of the fixed electrode and the connecting conductor to buffer the impact force on the fixed electrode when the movable electrode is closed to the fixed electrode. vacuum breaker. 2. The vacuum breaker according to claim 1, wherein the first and second metal shock absorbers are disc springs.
