Claims

[Scope of utility model registration request]

(1) A pair of lead rods that can be relatively moved toward and away from each other are provided, hermetically penetrating the vacuum container, and an arc electrode is connected to the inner end of each lead rod through 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 surface that contacts the other electrode, and a high-profile portion located on the back side of the contact portion. an adapter having at least two radial arms made of electrically conductive material, the inner ends of which are connected to said lead rod; A coil electrode, which 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 each outer end portion at one end and extending in a curved manner in the circumferential direction. The tip of the arc portion of the coil electrode in the extending direction is connected to the outer end of the arm of the adapter, and the high resistance spacer is connected to the back side of the arc electrode without contacting the adapter. Vacuum interrupter with special features.

(2) The vacuum interrupter according to claim 1, wherein the arm of the adapter is provided with a connecting portion to a coil electrode at an outer end thereof.

(3) The vacuum interrupter according to claim 2, wherein the connecting portion provided at the outer end of the arm of the adapter has an arcuate shape extending in a circumferential direction.゛
