摘要： A puffer-type gas blast circuit breaker is capable of restraining reduction in creepage insulation resistance of an insulating support and an insulating rod due to insulating gas of high temperature. An electrode section is mounted on a stationary member supported on an insulating support, and a stationary side arc contact and moving side arc contact are disposed facing each other to contact and separate; a hollow piston rod and an insulating rod are connected to the moving side arc contact, and inserted in a stationary member body portion; and a gas flow blocking member is mounted on an end of the piston rod to prevent an insulating gas heated and coming to the stationary side from getting into the insulating rod side. The stationary member body portion is formed cylindrical so that a gap between the body portion of the stationary member and the gas flow blocking member is minimized.

摘要： The gas insulated switchgear includes a rotary shaft which penetrates a pressure vessel is connected with a moving parts which is housed in the pressure vessel by way of a lever, and is connected to the moving parts, and brackets which support the rotary shaft and are mounted on a mounting portion which is formed on the pressure vessel. The brackets are fixed to the mounting portion formed on the pressure vessel using a plurality of fixing bolts which are arranged in a spaced-apart manner on an eccentric circle having the center at a point x2 offset from the center of rotation x1 of a rotary shaft and hence, the brackets can be fixed to the mounting portion formed on the pressure vessel at a predetermined angular position which uses the point x2 offset from the center of rotation x1 of the rotary shaft as the center of rotation.

摘要： When electric discharging occurs inside a gas insulated apparatus in which sulfur hexafluoride is filled, hydrogen-fluoride gas is generated, which abrades a part formed of glass fiber reinforced plastics included in the apparatus. Previously, resin for preventing the abrasion has been coated on the surface of the part; however, a problem has occurred that the coating film peels off. Organic fiber woven cloth woven using organic fiber such as aramid fiber or the like having hydrogen fluoride resistance and mechanical toughness is wrapped around the surface of glass fiber reinforced plastics, and thermosetting resin is wettably impregnated into weave patterns of the organic fiber woven cloth and then heat cured; thereby, an abrasion-preventing protection layer that does not peel off is formed.
