Electrode for vacuum interrupter

Abstract

Disclosed is an electrode for a vacuum interrupter, capable of reducing damage of contacts due to heat concentration to the center of the contacts, by reducing magnetic flux concentration to the center of the electrode, and capable of rapidly extinguishing an arc by diffusing the arc by forming a wide range of magnetic flux. The electrode for a vacuum interrupter comprises: 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 formed 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 formed 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.
