Title:
GAS INSULATED SWITCHGEAR
Document Type and Number:
WIPO Patent Application WO/2019/093071
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a gas insulated switchgear, the dielectric strength of which is improved. To solve this problem, the gas insulated switchgear of the present invention is provided with: a circuit breaker for interrupting current; a circuit disconnector for switching voltage; a ground switch; a main circuit conductor for electrically connecting the circuit breaker, the circuit disconnector, and the ground switch; and an insulator 1 for supporting the main circuit conductor. A non-linear resistance material 2 comprising a resistance material 7 having a nanometer size and a resistance material 8 having a micrometer size is added to the insulator 1.
