SF6 Breakers principle prices

The SF6 circuit breaker adopts a self-energizing arc extinguishing structure, which mainly uses the high-pressure thermal expansion airflow in the pressure cylinder and the blocking effect of the hitting arc to increase the gas pressure in the high-pressure cylinder at the opening of the circuit breaker. The operation of SF6 circuit breaker is divided into two types: one is opening operation ...

  • Sulfur hexafluoride circuit breaker - Wikipedia

    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.
