GAS INSULATED ELECTRIC EQUIPMENT

摘要

A gas insulated electrical equipment includes: a metal enclosure (2) having an insulating gas introduced therein; a conductor (3) that is accommodated inside the metal enclosure (2) and to which voltage is applied; and an insulating and a supporting member (4) insulating and supporting the conductor (3) relative to the metal enclosure (2). The conductor (3) is circumferentially covered with a dielectric film (5), and furthermore, a nonlinear resistance film (6) provided on the dielectric film (5) and having a nonlinear volume resistivity decreasing when the nonlinear resistance film is acted on by an electric field higher than a critical value.
