Title:
GAS BREAKER
Document Type and Number:
WIPO Patent Application WO/2019/073660
Kind Code:
A1
Abstract:
The purpose of the present invention is to enhance both ground insulation performance and breaking performance by reducing the amount of discharge of high-temperature and high-pressure gas into an insulating support cylinder while still moderating the influence on breaking operation by reducing the sliding resistance of an exhaust pipe. In order to achieve the above-described purpose, a gas breaker according to the present invention is characterized in that a shaft guide that is provided on an inner circumferential section of a movable-side main conductor, that moves along an inner circumferential surface of an exhaust pipe provided on the outer circumference of an exhaust shaft and an operating rod, and that links the operating rod and the exhaust shaft is provided with a gas suppressing means in order to suppress the discharge of heated and pressurized insulating gas, the gas suppressing means formed of: a protruding section which is axially adjacent to a sliding member that slides without a gap with respect to the exhaust pipe, which is formed on a horizontal surface of the shaft guide, said horizontal surface facing the exhaust pipe, and which forms a gap with respect to the exhaust pipe; and an enlarged section which is adjacent to the protruding section, and in which a gap with respect to the exhaust pipe is enlarged.
