Quantitative SF6 insulated monitor and record

Quantitative SF6 insulated monitor and record

General Information. The quantitative leak alarm system is mainly used in the 35kV sf6-gas switch room and 110kV, 220kV and 500kV GIS room in the substation to monitor the sf 6 gas leakage in the environment of the sf6-gas combined electrical equipment room and the oxygen content in the air in real time.. When sf6-gas gas leaks, the density of sf6 gas gas is more than 5 times that of air, which ...
