    Q: Can the circuit breaker interrupt if there is a leak and no SF 6 gas is available? A: Yes, the vacuum interrupters are independent of the SF 6 gas and all the interruption occurs inside the vacuum interrupters. SF 6 gas is only used for insulation.. Q: What is the probability of SF 6 leakage? A: The low leakage rate is possible as the normal pressure is 1.5 bar (22 psig) or less, as the SF

  • SF6 Circuit Breakers - Construction, Types and Working

    In an SF6 Circuit breaker, sulphur hexafluoride gas is used as the arc quenching medium.. The sulphur hexafluoride gas (SF6) is an electronegative gas and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure flow sulphur hexafluoride (SF6) gas and an arc is struck between them.
