• Sulfr hexafluoride gas in medium-voltage switchgear - Siemens USA

    The process is reversible, so that nearly all of the sf6 gas recombines after interruption. Thus, very little of the insulating gas is "used up" during interruption, particularly for interruption of moderate (load) currents. sf 6 dissociates during arcing into its atomic constituents, one sulfur atom and six fluorine atoms.

  • gaz sf6 circuit breaker maintenance - Siemens USA

    The first generation of sf6 gas circuit breakers was the lower voltage classes of 72kV and 145kV. As gaz sf6 breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing sf 6 as the line-to ground dielectric insulation.

    Siemens typically performs several radiological exposures per phase to ensure that critical components are revealed. This varies with the circuit breaker voltage class and if problems are identified during inspection. For a 72-145kV class Sulfr hexafluoride dead tank breaker, two to three exposures per phase are required to provide adequate data.
