  • SF6 Circuit Breakers - Construction Working Principle

    In the closed position of the SF6 circuit breaker, the contacts remain surrounded by SF6 gas at a pressure of about 2·8 kg/cm2.When the breaker operates, the moving contact is pulled apart and an arc is struck between the contacts. The movement of the moving contact is synchronised with the opening of a valve which permits SF6 gas at 14 kg/cm2 pressure from the reservoir to the arc
