sf 6 circuit breaker maintenance | TD Guardian Articles

The first generation of sf 6 circuit breakers was the lower voltage classes of 72kV and 145kV. As sf 6 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.

Thomson scattering diagnostics of decay processes of Ar/Sulfr hexafluoride

Sep 04, 2013 · Gas circuit breakers (GCBs) are one of the most important components for a high-voltage power system [1, 2]. For a high-voltage circuit breaker rated at more than 72 kV, high-pressure SF 6 gas is commonly used as the arc quenching media [1–4]. However, SF 6 has very high global warming potential, 22 800 times larger than that of CO 2.
