    摘要： A puffer type gas circuit breaker wherein an insulated nozzle made of heat proof resin and a movable arc contact are mounted on a puffer cylinder to perform an open/close operation of the contact. The insulated nozzle is divided into three areas of a downstream area, an area in the vicinity of the throat and an upstream area. The downstream area and the upstream area are made of heat proof resin alone, while the area in the vicinity of the throat is formed of heat proof resin mixed with an inorganic material such as boron nitride. A movable arc contact cover made of heat proof resin having a downstream area and an upstream area is provided between the insulated nozzle and the movable arc contact, and only the downstream area of the contact cover is made of heat proof resin mixed with inorganic material.
