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

Oct 23, 2020 · During operation of insulating gas 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 Sulfr hexafluoride circuit breaker is a little bit different in modern time. The innovation of puffer type design makes the operation of gaz sf6 CB much easier.Get price
