When a large number of SF6 gas leaks occur in high-voltage electrical equipment, emergency protective measures should be taken to evacuate the gas leak site, and the relevant leaders of the company should be reported immediately. When poisoning occurs, personnel should be immediately evacuated from the scene and transferred to a well-ventilated place for rest.

Substation outage maintenance is not directly related to Weavers' SF6 leakage monitoring alarm, as long as the system remains powered on, when excessive leakage occurs, it must generate an alarm and control the operation of the automatic fan. Unless the host and fan power supply is also in a state of power failure. In order to avoid the occurrence of this situation, the monitoring host power input should be connected to the uninterrupted power circuit during installation.

The source of surface contamination is likely to be impurities during equipment assembly and metal particles generated during switch operation, which will reduce flashover voltage and increase dispersion. In addition, arc discharge and corona discharge during operation will cause SF6 gas decomposition to produce low fluoride SF4, SOF2, SO2F2, etc. Under the action of water and oxygen, corrosive HF and SO2 will be generated, making the insulation material corroded and deteriorated, and the insula

SF6 electrical equipment under normal operation, SF6 impurities can generally be treated on site to remove. The treated SF6 gas must meet the reuse standard, and the SF6 gas is recharged to the electrical equipment for reuse.
