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

Oct 23, 2020 · Here gaz sf6 gas was compressed and stored in a high-pressure reservoir. 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 insulating gas 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.Get price

What is Sulfr hexafluoride Circuit Breaker? Construction, Working Principle

The displacement of the moving contacts is synchronised 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 SF 6 gas absorbs the free electrons in the arc path and forms ions which do not act as a charge carrier. These ions increase the dielectric strength of the gas and hence the arc is extinguished. This process reduces the pressure of the SF 6 gas up to 3kg/cm^2 thus; it is stored in the low-pressure reservoir. ThisGet price
