The arc extinguishing medium and insulating medium of sulfur hexafluoride high-voltage electrical equipment are sulfur hexafluoride gas, which cannot leak or liquefy. If leakage or liquefaction occurs, the reliable and safe operation of sulfur hexafluoride high-voltage electrical equipment cannot be guaranteed. Therefore, it is very necessary to ensure that the sulfur hexafluoride gas of sulfur hexafluoride high-voltage electrical equipment does not liquefy. Utility Model Content
