Title:
GAS INSULATED SWITCHING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2012/081264
Kind Code:
A1
Abstract:
A gas insulated switching apparatus of the present invention is provided with: a grounded tank within which a breaker is to be housed; current-transformer mounting cylindrical bodies mounted onto the grounded tank; porcelain bushings mounted onto the current-transformer mounting cylindrical bodies; and main circuit conductors inserted through the porcelain bushings and the current-transformer mounting cylindrical bodies. Each of the main circuit conductors is composed of a first main-circuit conductor that is connected to the breaker, and that is positioned within the porcelain bushing; and a second main-circuit conductor that is connected to the first main-circuit conductor and a main circuit terminal. The gas insulated switching apparatus has formed thereon: insulators that are formed at areas of the first main-circuit conductors positioned at the current-transformer mounting cylindrical body sections, and formed in extension downwards from the lower ends of the current-transformer mounting cylindrical bodies, and in extension towards the vicinity of connecting sections of the first main-circuit conductors and the second main-circuit conductors; and grounding shields that are arranged within the insulators, and formed in extension downwards from the lower ends of the current-transformer mounting cylindrical bodies, and in extension upwards from connecting sections of the current-transformer mounting cylindrical bodies and the porcelain bushings.
