  • SF6 Circuit Breaker Types, Working Principles Maintenance.

    Feb 20, 2021 · In a high-voltage circuit breaker like SF6, current interruption is achieved by separating the contacts in a gas medium. The sf6 comprises both fixed and movable contacts enclosed in a gas system at a pressure of around 2.8 kg/cm 2. Whenever a fault arises, the movable contacts separate, and an arc strikes in between them.

  • What is SF6 Circuit Breaker? - Codrey Electronics

    Jul 31, 2020 · SF6 Circuit Breaker The displacement of the moving contacts is synchronized with the valve which enters the high-pressure SF 6 gas in the arc interrupting chamber at a pressure of about 16kg/cm^2. The SF6 gas absorbs free electrons in the arc to form relatively immobile negative ions. This is arcing contact separation.
