GAS INSULATED SWITCHGEAR, CAPABLE OF REDUCING SIZE AND MANUFACTURING COST BY INTEGRATING DISCONNECTING SWITCH, EARTHING SWITCH FOR AMENDMENT, AND EARTHING SWITCH FOR LINE

摘要

PURPOSE: A gas insulated switchgear is provided to individually perform earth connection upon its utility, by operating earthing switch for amendment or line respectively.;CONSTITUTION: A container(110) is formed in a T shape. Each of the first or third ends of T shape shuts tightly with the flange. The structures of the first and second ends are formed with being faced each other. The first and second earthing switches are installed in both ends of an inner wall of the third end. The first and second earthing switches comprise the first and second earth movable elements(162,172) operated independently. The first and second fixed conductors(120,130) are protruded to each of the first and second ends' inner direction. The first and second fixed conductors are connected through the first and second earth movable elements to the first and second earthing switches. The movable element(140) connects the first and second fixed conductors electrically. The driver unit moves the movable element.;COPYRIGHT KIPO 2013
