What is sf6 gas 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
