gascircuit breakers fittings for middle voltages

OverviewOperating principleBrief historyDesign featuresGenerator circuit breakersHigh-power testingIssues related to SF6 circuit breakersComparison with other typesSulfur 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(SF6) gas to cool and quench the arc on opening a circuit. Advantages over other media include lower operating noise and no emission of hot gases, and relatively low maintenance. Developed in the 1950s and onward, SF6 circuit breakers are widely used i…
