Abstract: A gas circuit breaker having a pair of contacts and a pair of exhaust conductors. An exhaust hole in the pair of exhaust conductors is provided with an insulation cover having an opening. The cover has a guide on an opening end on the side near the pair of contacts and an opening end on the side far from the pair of contacts respectively. The guide has an exhaust hole protective guide and a high-temperature gas passage dividing guide. A first gas flow passage is between an exhaust hole protective guide and a high-temperature gas passage dividing guide, and a second gas flow passage is between the high-temperature gas passage dividing guides. The first gas flow passage is narrower than the second gas flow passage. An end of the exhaust hole protective guide on the first gas flow passage side is projected toward the high-temperature gas passage dividing guide.

Abstract: A gas circuit breaker is configured by comprising a tank filled with arc extinguishing gas, a pair of fixed side arc contact and moving side arc contact in the tank, a puffer chamber formed with a puffer cylinder including the moving side arc contact at its end and a fixed piston, and an insulating nozzle, attached to the end of the puffer cylinder, surrounding the moving side arc contact, that forms a flow channel to guide arc extinguishing gas from the puffer chamber to the contacts. A puffer cylinder 104 has a cylindrical member 104a at a breaker side end, an end of the insulating nozzle 101 is provided in the cylindrical member 104a. And the gas circuit breaker is configured by further comprising a hollow moving side main contact 102 at a breaker side end of the cylindrical member 104a, a pressing metal fitting 103 to engage an insulating nozzle 101 in the hollow part of the moving side main contact 102.
