Claims

[Scope of utility model registration request]

A vacuum container is formed by closing the openings at both ends of an insulating cylinder with metal flanges, and a pair of electrode parts that can be freely moved into and out of contact with each other are arranged inside this vacuum container. , in a vacuum valve having a coil electrode having an arm extending radially from the center and a coil part curved in an arc shape from the tip of the arm, the coil part of the coil electrode is arranged so that one end is placed on the back surface of the electrode and the other end is arranged. are electrically connected to electrode shafts, and the electrode shafts are provided with slits that divide the current and allow the current to flow in an arc shape.
