摘要:
The present invention relates to a 3-way disconnector and earth switch for a gas insulated switchgear, and more particularly, to a 3-way disconnector and earth switch for a gas insulated switchgear capable of preventing a loss of energy under a structure that the disconnector and the earth switch are not interworked with each other even if they are moved by the same driving lever. The 3-way disconnector and an earth switch for a gas insulated switchgear includes: a movable portion including a disconnector movable portion and an earth switch movable portion; a disconnector mover and an earth switch mover installed in the disconnector movable portion and the earth switch movable portion so as to be linearly movable; a driving lever rotatably installed between the disconnector mover and the earth switch mover; and a first lever and a second lever rotated by receiving a rotational force of the driving lever, and configured to move the disconnector mover and the earth switch mover, respectively, wherein a driver is protruded at one side of the driving lever, and a driving pin is provided at an end of the driver, and wherein the driving pin is configured to selectively move one of the first and second levers.
