HIGH VOLTAGE DISCONNECTING SWITCH INCLUDING COPPER-TUNGSTEN ADHERED TO END PART OF MOVING ARC CONTACT AND FIXING ARC CONTACT

摘要

PURPOSE: A high voltage disconnecting switch is provided to reduce a manufacturing cost by adhering copper-tungsten for adsorbing arc currents to an end part of a moving arc contact and a fixing arc contact. CONSTITUTION: A high voltage disconnecting switch comprises a fixing arc contact(16) fixed at the center of inner part of a fixing contact and connected to a first conductor; a moving arc contact(14) connected to a second conductor and making the second conductor contact to the first conductor by moving and contacting to an end part of the fixing arc contact; a coil spring(18) for separating rapidly the moving arc contact from the fixing arc contact; and a stop ring(19) for setting the standard for the length of the coil spring.
