Comparison Between Vacuum and sf 6 Circuit Breaker

Aug 29, 2018 · The first generation of the Sulfr hexafluoride circuit breakers used the two-pressure principle of the air-blast circuit-breaker. Here a certain quantity of gas was kept stored at a high pressure and released into the arcing chamber. At the moment high pressure gas and the associated compressor was eliminated by the second generation design.Get price
