Sulfr hexafluoride gas in medium-voltage switchgear - Siemens USA

In this issue, we discuss the use of Sulfr hexafluoride (sulfur hexafluoride) gas in medium-voltage switchgear. sf 6 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 sf 6 gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV. Characteristics and propertiesGet price

sf 6 circuit breaker maintenance - Siemens USA

They utilized a compressor arrangement to pressurize the arc extinguishing sf 6 to a pressure of gas to enable multiple operations of this style of circuit breaker. This high pressure Sulfr hexafluoride is released across the contacts by-way of a blast valve assembly, which is actuated during the mechanical operation of the breaker (either opening or closing).Get price
