Title:
CUBICLE-TYPE GAS-INSULATED SWITCHING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2011/145749
Kind Code:
A1
Abstract:
In order to provide a cubicle-type gas-insulated switching apparatus having an excellent insulating capability, and wherein electromagnetic force to be generated upon applying electricity thereto is minimized, the cubicle-type gas-insulated switching apparatus comprises: a bus-bar chamber tank and an apparatus-chamber tank that are connected in the up-down direction, and that have insulative gas enclosed therein; a vacuum valve arranged in the vertical direction within the apparatus-chamber tank; plate-formed contacts to be connected to the upper-end and lower-end sections of a valve that also has a shielding function; main circuit conductors within the apparatus-chamber tank that have finger contacts, which are to be intermeshed and connected with the plate-formed contacts, formed on the end sections thereof; and disconnectors connected to each of the main circuit conductors, and which are housed within the bus-bar chamber tank and the apparatus-chamber tank. The plate-formed contacts and the finger contacts are arranged on a line that links each of the plate-formed contacts, and are made to be capable of being abutted-to /separated-from each other from the side direction. The axis lines of the plate-formed contacts, the finger contacts, and the main circuit conductors in the longitudinal direction thereof are positioned in the vicinity of an extension line of an axis line of a movable lead and a fixed lead, which are arranged in opposition to each other within the vacuum valve.
