Eco-efficient alternatives to gaz sf6: Continuing the AirPlus

May 30, 2019 · Up to now facing the ‘switching challenge’ has been circumvented by using vacuum interrupters, where switching happens outside the insulation gas. The use of vacuum interrupters facilitated the first generation of eco-efficient RMUs, compensating the poorer arc-quenching performance of climate-friendly insulation gases compared to SF 6 .

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 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, insulating gas circuit breakers are wid
