Description of the invention (3) As shown in the figure, < Insulating bushing 3 and flange 5, A capacitor 7 is arranged around the outer periphery of 6. Once the circuit breaker or grounding switch of the gas-insulated switchgear is operated, a high-frequency surge of several megawatts or more is generated at the flanges 5 and 6. Once the voltage exceeds tens of thousands of volts, the insulation of the insulated bolt 4 will jump. fire. A capacitor 7 using an insulating film as a dielectric is arranged around the bushings 3, the flanges 5, 6 to prevent flashover. As shown in Fig. 2, the capacitor 7 of this embodiment is constituted by a capacitor body 12 using an insulating film and a cover _ 1 3 provided on the outer periphery thereof. As shown in FIG. 3, the capacitor body 12 is mainly composed of the main electrodes 14, 4, 5, and auxiliary electrodes 16 and 17, for forming a capacitor, and an insulating film 1 stored between the auxiliary electrodes 1, 6, and 17. Constituted by 8. The main electrodes 1 4 ′ 1 5 are respectively provided with respect to the flanges 5 and 6. Auxiliary electrodes 1 6 and 17 are connected to the respective main electrodes 1 4 and 15. The auxiliary electrodes 16 and 17 are interactive. Build up.
