Problems solved by technology

[0002] Sulfur hexafluoride is an important insulating and arc-extinguishing gas for high-voltage electrical equipment in GIS. Leakage of sulfur hexafluoride is a relatively common defect in power stations, which poses a great safety hazard to the operation of high-voltage electrical equipment in GIS
At present, defects are only discovered when the pressure of sulfur hexafluoride exceeds the limit, which is not conducive to the safe and stable operation of the switch station
