  • SF6 Circuit Breakers - Construction, Types and

    10 mins readThe types of SF6 circuit breakers can be broadly identified as. Double pressure Type SF6 CB; Single Pressure Puffer Type SF6 CB; In double pressure type SF6 circuit breaker, the gas from the high-pressure system is released into the low-pressure system through a nozzle, during the arc extinction processes. This design has become obsolete.

  • Nameplate details of SF6 Circuit Breaker | Explained

    Jun 14, 2020In SF6 circuit breaker, arc extinguishes during current zero. As in 3 phase AC circuit, currents are out of phase by 120&, current interruption in breaker is not simultaneous. Contact of one pole will open before the other two. And hence, the power frequency recovery voltage across the first pole to open is more than the other two.
