SF6 gas has a century-old history, it is two French chemists Moissan and Lebeau synthetic artificial inert gas in 1900, around 1940, the United States military used it for the Manhattan Project (nuclear military). Commercially available in 1947. At present, SF6 gas is mainly used in the power industry. SF6 gas is used in 4 types of electrical equipment as insulation and/or arc extinguishing; SF6 circuit breakers and GIS (in this case, sulfur hexafluoride enclosed combination appliances, internat

SF6 leak detector is an effective inspection tool for SF6 electrical equipment leak detection, and it is necessary to use the instrument in the handover and overhaul. And we have to detect the leakage of the switch every year, and make the corresponding SF6 electrical equipment leakage report is an essential workflow.

SF6 gas density relay working principle 1.SF6 gas density relay is a SF6 gas package sealed outside the bellows 1 and connected with the SF6 gas in the circuit breaker. Through the lever 6 with shaft 5 as the support point, it is compared with the standard gas package 3 sealed outside the bellows 2 to drive the electric contact 4 of the micro switch to realize its signal and lock function.
