gas 160 circuit breakers principle rental

Operating principle. Current interruption in a high-voltage circuit breaker is obtained by separating two contacts in a medium, such as sulfur hexafluoride (SF 6), having excellent dielectric and arc-quenching properties. 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 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 28 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
