GD8000C SF6 Gas Leakage Alarm Online Monitoring System General Information The quantitative leak alarm system is mainly used in the 35kV SF6 switch room and 110kV, 220kV and 500kV GIS room in the substation to monitor the SF6 gas leakage in the environment of the SF6 combined electrical equipment room and the oxygen

For still higher voltage, air blast vacuum or SF6 cut breaker are used. The use of SF6 circuit breaker is mainly in the substations which are having high input kv input, say above 220kv and more. The gas is put inside the

2021-3-17In an SF6 Circuit breaker, sulphur hexafluoride gas is used as the arc quenching medium.. The sulphur hexafluoride gas (SF6) is an electronegative gas and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure flow sulphur hexafluoride (SF6) gas and an arc is struck
