Publication number: 20040211757Abstract: To reduce the size of a gas-insulated switch for the purpose of utilizing the space of a power station or substation effectively and improving the economy thereof. A gas-insulated switch equipped with a fixed contact and a moving contact that can contact with and separate from the fixed contact, wherein the breakage of the moving contact is operated with a single shock absorber in both the breaking action and the closing action of the moving contact. As a result that use of the gas-insulated switch according to the present invention improves the overall energy efficiency of components, a device with further reduced driving energy can be realized for a gas-insulated switch of the same specification.Type: ApplicationFiled: May 20, 2004Publication date: October 28, 2004Applicant: Hitachi, Ltd.Inventors: Hideo Kawamoto, Kenichi Okubo, Tetsu Ishiguro

Patent number: 6696657Abstract: 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.Type: GrantFiled: November 18, 2002Date of Patent: February 24, 2004Assignee: Hitachi, Ltd.Inventors: Makoto Hirose, Hideo Kawamoto, Tetsu Ishiguro
