After contact separation, current is carried through an arc and is interrupted when this arc is cooled by a gas blast of sufficient intensity. SF6 gas is electronegativeand has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high pressure flow of sulfur hexafluoride gas, and an arc is st…See more on en.wikipedia.orgEstimated Reading Time: 12 minsPeople also askWhat is the working principle of SF6 circuit breaker?What is the working principle of SF6 circuit breaker?Working Principle of SF6 Circuit Breaker. The contacts of SF6 Circuit Breaker are surrounded in an environment of SF6 gas at some pressure. Actually, the dielectric strength of SF6 gas is directly proportional to its pressure. In 220 kV, 400 kV and 765 kV applications, the gas pressure is maintained at 6.5 bar.SF6 Circuit Breaker – Construction, Working Principle and Types
