sf 6 process for Siemens

Sulfur hexafluoride, sf6 gas, is used around the world as a dielectric medium for high-voltage circuit breakers, switchgear, and other electrical equipment.Additionally, it is used for the filling of insulated windows and for the casting of magnesium. sf6 is expensive and is also a powerful green house gas (20,000 times more potent than CO 2). GENERON membranes allow sf6 to be retained at ...

  • SF6 gas in medium-voltage switchgear - Siemens USA

    SF6 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 SF6 gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV. Characteristics and properties

    As of 2010, the mean time to failure (MTTF) for Siemens power vacuum interrupters had exceeded 57,000 interrupter years, illustrating that loss of vacuum is an extremely remote occurrence. In contrast, an SF 6 interrupter requires a sliding or rotating seal at the point where the mechanism penetrates the wall of the interrupter chamber.
