Title:
TANK-TYPE VACUUM INTERRUPTER
Document Type and Number:
WIPO Patent Application WO/2011/052206
Kind Code:
A1
Abstract:
Disclosed is a tank-type vacuum interrupter that utilizes a solid or hollow cylinder insulation rod at the junction between the operating mechanism and the vacuum valve. The operating mechanism and the vacuum valve are connected to the insulation rod by rod-like pins, and to prevent the insulation rod itself from falling, the pins connecting the operating mechanism and the vacuum valve are offset by 90°. As a result, the insulation rod is prevented from falling without an increase in weight because the number of components is does not increase (since insulation supports, insulation support tubes, and bolts for fastening these are not necessary to provide mechanical strength), and it is not necessary to increase the size of the assembly components around the insulation rod.
