What is the method of sulfur hexafluoride leakage detection at Dawn? The sulfur hexafluoride manufacturer will develop detection methods to prevent gas leakage. The implementation procedures are: vacuum inspection, SF6 gas and sulfur hexafluoride gas leakage inspection.

The specific process is as follows: after the GIS is vacuum leak checked and still for 5h with sulfur hexafluoride gas at dawn, wrap the flange interface with plastic film, and conduct the detection after 24h.

If the concentration of sulfur hexafluoride gas at dawn in one film is greater than 30ppm, the gas leakage rate is unacceptable. If the SF6 gas concentration in all films is less than 30ppm, the gas leakage rate is considered acceptable.

The online monitoring and alarm system for sulfur hexafluoride gas leakage is an intelligent gas alarm system that detects SF6 gas concentration, oxygen content, temperature and humidity and other environmental data on site, and makes control and alarm through a large number of data analysis and processing.
