News Detail
  • SF6 circuit breaker maintenance - Siemens USA

    The first generation of SF6 circuit breakers was the lower voltage classes of 72kV and 145kV. As SF6 breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing SF6 as the line-to ground dielectric insulation.

  • TCP high-voltage SF6 power circuit breaker - Siemens USA

    This valve was changed in January 1992 to W43840801. This valve is of the direct acting ball type and will fit directly into the cavity of the earlier valve. The current valve has solved the problem of leaking relief valves and can be obtained from SEA at no charge. The new valve uses crushable copper washers as a means of sealing to atmosphere.

  • Hints for maintaining type SP SF6 power circuit - Siemens USA

    The air valve heater is used for two functions: to prevent condensation inside the mechanism and to prevent ice from freezing up the valve during operation when the ambient temperature is approximately 45 degrees Fahrenheit and below. Siemens has developed an alternate heater arrangement since we need to retain both of the above functions.

  • SF6 gas in medium-voltage switchgear - Siemens USA

    In this issue, we discuss the use of SF6 (sulfur hexafluoride) gas in medium-voltage switchgear. 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.
