Document Type and Number:
WIPO Patent Application WO/2019/220655
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a vacuum valve with which it is possible to improve conductive performance while inhibiting an increase in the diameter of a bellows. A vacuum valve (100), provided with a cylindrical insulating container (11), a fixed-side end plate (12) joined to one end of the insulating container (11), a movable-side end plate (13) joined to the other end; a fixed-side electrode rod (14) joined to the fixed-side end plate (12); a movable-side electrode rod (15) joined to the movable-side end plate (13) via a bellows (16); a fixed-side electrode (17) joined to an end part of the fixed-side electrode rod (14); and a movable-side electrode (18) joined to an end part of the movable-side electrode rod (15). The movable-side electrode rod (15) is provided with: a small diameter part (SR1), which has a smaller diameter than the inside diameter of the bellows (16) and which penetrates through the bellows (16); and a large diameter part (LR1), which has a larger diameter than the inside diameter of the bellows (16) and which is at least partially disposed in the insulating container (11).
