On-site Practice on SF6 Switchgear Leak Detection and the Leaking Point Treatment

This article summarized the SF6 switchgear gas leakage characteristics,the on-site performance and the reason;discussed the venture decision questions: the disintegration to eliminate leaks and the stoppage leaks with pressure;introduced the froth law,qualitative leak detector alarm leak detection law,the wrap add the quota leak detector leak detection law,the laser image formation leak detector law and so on the commonly used leak detection method;elaborated the leak detection method choice viewpoint;carried on the theoretical calculation of the stoppage leaks with pressure,introduced several leaking point elimination method;finally introduced several scene leak detection and the leaking point processing illustrative case.
