Abstract

In the present invention the operating speed of a rod for transmitting an operating force of a manipulation mechanism to a movable electrode section is improved. One end of a first link is connected to one end of an operating rod which is connected to a movable electrode section housed inside a container filled with an insulating gas. One end of an amplification lever is connected to the other end of the first link and one end of a second link is connected to the other end of the amplification lever. One end of a support bearing fixed to a partition wall of the container is connected to the other end of the second link and one end of a sealed rod is connected to substantially the center of the amplification lever. One end of a third link is connected to the other end of the sealed rod and the other end of the third link is connected to an output section of the manipulation mechanism. A support link initial angle (?) is set in the range of 2° to 0° said support link initial angle being an angle formed by a second straight line (12c) on the second link (12) and the motion axis line (14c) of the sealed rod (14).
