Comparison Between Vacuum and gaz sf6 Circuit Breaker

Aug 29, 2018 · The first generation of the sf6 gas 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

insulating gas Circuit Breaker Types, Working Principles Maintenance.

Feb 20, 2021 · In a high-voltage circuit breaker like gaz sf6, current interruption is achieved by separating the contacts in a gas medium. The sf6 comprises both fixed and movable contacts enclosed in a gas system at a pressure of around 2.8 kg/cm 2. Whenever a fault arises, the movable contacts separate, and an arc strikes in between them.Get price
