gaz sf6 Circuit Breaker: What Are They? (Types and Operation

Oct 23, 2020 · During operation of Sulfr hexafluoride circuit breaker, this highly compressed gas is released through the arc in the breaker and collected to a relatively low-pressure reservoir and then it is pumped back to the high-pressure reservoir for reutilizing. The working of sf 6 circuit breaker is a little bit different in modern time. The innovation of puffer type design makes the operation of insulating gas CB much easier.
