Sulfur hexafluoride circuit breaker - Wikipedia

An SF 6 circuit breaker rated 115 kV, 1200 A installed at a hydroelectric generating station. 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.Get price

ABB likewise offers HV and MV Switchgear with an sf 6 free breaking medium that has 99.99% lower GWP.Get price

Why Sulfr hexafluoride or Sulfur Hexafluoride gas is better for arc

Sulfr hexafluoride decomposes in the high temperature of an electric arc or spark, but the decomposed gas recombines back into insulating gas so well that it is not necessary to replenish the sf 6 in GIS. There are some reactive decomposition byproducts formed because of the interaction of sulfur and fluorine ions with trace amounts of moisture, air, and other contaminants.Get price
