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.

摘要： Each outermost part of fixed-side connection conductors, fixed-side fixed contacts, movable-side fixed contacts, and movable-side connection conductors are placed outside of an outermost diameter of a fixed-side conductor and a movable-side conductor, as viewed from an axis line of the fixed-side conductor and the movable-side conductor as a center. This arrangement provides a power switchgear that can diminish mutual effects of currents among conduction parts to suppress decrease in a current-carrying capacity for each of the conduction parts and to increase a current-carrying capacity for a total of the conduction parts, without increasing the size of the switchgear.
