Title:
ELECTRODE FOR VACUUM VALVE AND ITS MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2006228454
Kind Code:
A
Abstract:
To aim at improvement of breaking performance of an electrode for a vacuum valve loaded on a vacuum circuit breaker an simplification of its manufacturing process.
A fixed electrode and a movable electrode are arranged on the same axis in opposition to each other in a vacuum valve. Each electrode 1 is formed of copper or a copper alloy with a conductivity of 40% IACS or more, and is composed of a conductive member 5 zoned into a plurality of grooves 2 extended from the center in a radius direction and formed in a windmill shape, and a contactor 3 fitted in protrusion toward an opposite side of each electrode at an outer periphery of each zone of the conductive member 5 and formed of a Cu-Cr alloy.
