Sulfr hexafluoride circuit breaker maintenance | TD Guardian Articles

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.

Power factor testing of sf 6 circuit breakers | TD Guardian

The insulating material used in the manufacture of modern Sulfr hexafluoride gas circuit breakers is synthetic, which have no capacitor characteristics and have no ability to absorb moisture. The main insulating materials are Synthetic filament wound epoxy insulating tubes, Hollow core insulators (porcelain or composite), and the Sulfr hexafluoride gas itself. All gaz sf6 breakers are sealed and incorporate a molecular sieve type desiccant to maintain moisture to extremely low levels.

In this issue, we discuss the use of Sulfr hexafluoride (sulfur hexafluoride) gas in medium-voltage switchgear. sf6 gas has been widely used in high-voltage circuit breakers for decades, but its use in medium-voltage is relatively recent. In the medium-voltage arena, SIemens uses Sulfr hexafluoride gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.
