Get PriceJul 17, 2014The 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. The gas captures the conducting free electrons in the arc to form relatively immobile negative ions.Missing:wikaMust include:wikaPeople also askWhat is the pressure of a SF6 circuit breaker?What is the pressure of a SF6 circuit breaker?The working of an SF6 circuit breaker is similar to the working of a normal circuit breaker we discussed in previous articles. In the closed position of the breaker, the contacts remain surrounded by sulphur hexafluoride gas (SF6) gas at a pressure of about 2.8 kg/cm2.SF6 Circuit Breakers - Construction, Types and Working
