Claims

[Scope of utility model registration request]

A pair of lead rods that can be moved relatively close to each other and separated from each other are provided hermetically through a vacuum container, and an arc electrode is provided at the inner end of each lead rod via a high-resistance spacer made of a material with low conductivity. , the arc electrode is formed of a material with low conductivity into a substantially disk shape, and has a contact portion in the center of one side that contacts the other electrode, and a high conductivity portion located on the back side of the contact portion. an adapter having at least a plurality of radially positioned arms made of 100% carbonaceous material, the plurality of arms having inner ends connected to the lead rod, and one end at each outer end of each of the arms; A coil electrode that generates an axial magnetic field is provided on the back side of the contact portion of the arc electrode, and includes a circular arc portion connected to the arc portion and curved and extended in the circumferential direction. 1. A vacuum interrupter, characterized in that the distal end in the installation direction and the outer end of the arm of the adapter are connected, and the arm of the adapter has a width dimension larger than a thickness dimension.
