Patent ID: 8263894

Claim:
An electrode for a vacuum interrupter, comprising: a contact electrode plate configured to provide contacts; an inner coil electrode formed of one electric conductor having an open loop shape, and through which a current flows in a first rotation direction; an outer coil electrode formed of one electric conductor having an open loop shape, concentrically arranged with the inner coil electrode at an outer side of the inner coil electrode in a radius direction, and through which a current flows in a second rotation direction opposite to the first rotation direction parallel to the current flowing to the inner coil electrode; a first conductive pin made of a conductive material, and configured to provide an electric current path by connecting the contact electrode plate and the inner coil electrode with each other; and a second conductive pin made of a conductive material, and configured to provide an electric current path by connecting the contact electrode plate and the outer coil electrode with each other.
