Abstract

This invention provides a switch gear of knife edge type in which a blade rotates to perform a switching operation, the switch gear having an improved voltage withstanding performance by moderating the electric field at an end of the blade. The switch gear has a rotating side terminal (3) connected to one main conductor 2, a blade (4) of a strip shape conductor member having one end rotatably supported onto the rotating side terminal (3), and a fixed side terminal connected to another main conductor (5) and configured to come in contact with and depart from another end of the blade (4). A shield member (13) having an insulation covering is fixed onto the blade (4) such that the shield member (13) covers a width surface of the blade (4). with the edge of shield (13) extending over the edge and the tip of the blade (4).
