Title:
HYBRID EXTINCTION-TYPE GAS CIRCUIT BREAKER FOR A GAS INSULATED SWITCHGEAR
Document Type and Number:
WIPO Patent Application WO/2012/002677
Kind Code:
A2
Abstract:
The present invention relates to a hybrid extinction-type gas circuit breaker, which can reliably eliminate an arc when a fault current is cut off, without a loss of pressure in the extinction gas. The hybrid extinction-type gas circuit breaker of the present invention comprises: a fixed unit having a fixed unit arc contact portion; and a moving unit including a cylinder, a piston arranged in the cylinder, a puffer chamber and a thermal expansion chamber formed by a separator wall, and an operating rod which passes through an interior of the piston and the cylinder, the moving unit further including a moving unit arc contact portion that can closely approach the fixed unit arc contact portion. A moving valve is arranged at one surface of the separator wall, wherein the moving valve includes a tight contact portion and a moving portion. The tight contact portion is movable by means of a difference in pressure, and is brought into tight contact with the separator wall. The moving portion extends from the tight contact portion, enables the operating rod to penetrate therethrough, and opens/closes the thermal expansion chamber.
