真空バルブ。[Scope of Claim for Utility Model Registration] (1) A vacuum container is formed by closing the openings at both ends of an insulating cylinder with metal flanges, and a pair of electrodes that can be freely moved toward and away from the vacuum container are disposed inside the vacuum container. The electrode is a main electrode, a contactor fixed to the surface of this main electrode,
The tip of the arm extending radially from the tip of the current-carrying shaft is curved in an arc shape, and this tip is fixed to the back surface of the main electrode.The coil electrode is made of a material with a resistivity value higher than that of copper, and one end is connected to the current-carrying shaft. A vacuum valve comprising a reinforcement whose other end is fixed to the main electrode, a protrusion is formed at the end of the reinforcement opposite to the side to which the current-carrying shaft is fixed, and the main electrode has a protrusion on the surface side. A vacuum valve characterized by having a recess into which the protrusion is inserted and locked, and a hole in the center through which the intermediate portion of the reinforcement passes. (2) The diameter and depth of the recess of the main electrode are D 1 and T 1 , the diameter of the through hole is D 2 , the diameter and thickness of the protrusion inserted into the reinforcement recess are D 3 and T 2 , and reinforcement When the diameter of the fixed side of the current-carrying shaft is D 4 , D 1 > D 3 > D 2 > D 4 and T 1 > T
1. A vacuum valve according to claim (1) of the utility model registration.
