Claims

[Scope of utility model registration request]

(1) A vacuum container whose interior is kept in a vacuum, electrodes placed opposite each other in the vacuum container, and a pair of electrode rods that hold the electrodes in a detachable manner, from the opposing surfaces of the electrodes. A vacuum breaker comprising: a hole provided at a predetermined depth; and a cavity provided in the electrode so as to communicate with the hole.

(2) The vacuum breaker according to claim 1, characterized in that the electrode comprises a counter electrode fixed to an electrode rod and a main contact fixed to the opposing surface of the counter electrode.

(3) The vacuum breaker according to claim 1 or 2, characterized in that a plurality of holes are provided.

(4) The vacuum breaker according to any one of claims 1 to 3 of the claims registered as a utility model, characterized in that a hole is provided that communicates with the cavity from the surface opposite to the facing surface of the electrode. .
