GAS INSULATED ELECTRIC EQUIPMENT

摘要

A gas insulated electric equipment comprises: a metal container (2) filled with an insulation gas; a conductor (3) housed inside the metal container (2) with a voltage applied thereto; and an insulation support member (4) for supporting the conductor (3) insulated from the container (2). The periphery of the conductor (3) is covered with a dielectric film (5), and is further covered with a nonlinear resistance film (6) formed on the dielectric film (5), the nonlinear resistance film (6) having a nonlinear volume resistivity that decreases when an electric field acting on the nonlinear resistance film (6) is higher than a critical value.
