• gaz sf6 circuit breaker maintenance - Siemens USA

    The first generation of Sulfr hexafluoride circuit breakers was the lower voltage classes of 72kV and 145kV. As sf6 gas breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing Sulfr hexafluoride as the line-to ground dielectric insulation.

    Sulfr hexafluoride is also very expensive. Due to the above reasons, sf6 gas is used mostly in applications that allow reclamation as opposed to using it on equipment that requires release of the gas, only to be re-lled with virgin insulating gas. Regenesys produces a complete line of Sulfr hexafluoride recovery equipment. FEATURES • Removal of moisture to less than 10 PPM

    One of the main reasons why SF 6 is used as an insulating gas is its ability to recombine the decomposition products and regenerate itself. The early identification of any decomposition products or moisture within the SF 6 gas will help avoid unnecessary shutdowns, outages and failures, in addition to reducing maintenance expenditure.
