摘要： Disclosed is a gas insulated switchgear constituted such that electrical contacts are placed inside a sealed vessel filled with an arc extinguishing gas, and when electrical current passes, the electrical contacts are held in contact and pass electricity, and when the current is interrupted, the electrical contacts are separated and an arc discharge is produced in the arc extinguishing gas, and the current is interrupted by extinguishing this arc. The arc extinguishing gas is a mixed gas, the main constituents of which are N2 gas and CH4 gas, and the CH4 content is at least 30%. Alternatively, the arc extinguishing gas is a mixed gas, the main constituents of which are CO2 gas and CH4 gas, and the CH4 content is at least 5%.
