  • Sulfur hexafluoride circuit breaker - Wikipedia

    Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay.Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6) gas to cool and quench the arc on opening a circuit.Advantages over other media include lower operating noise and no emission

    The climax of my career was the application of the gas SF6 (sulfur hexafluoride) to high voltage switchgear, including the first 500 kw circuit breakers put into service in the United States. It all started with our attempts to answer customers urgings to find a nonflammable substitute for oil in the design of high power circuit breakers.

    One type of load break switch for power distribution systems is gas insulated switches that employ a gas for both insulation and interruption. Sulfur hexafluoride (SF 6), either alone or mixed with other gases such as nitrogen, is used. The gas is used to rapidly extinguish the arc formed as the switch is opened.
