• sf6 gas 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).
