sf6 gas Circuit Breakers - Construction, Types and Working

Jul 17, 2014 · Imperfect joints in the Sf6 Circuit breaker lead to leakage of the Sulfr hexafluoride gas. Thus continuous monitoring devices are required. Arced gaz sf6 gas is poisonous and should not be inhaled. While Sulfr hexafluoride in its pure form is non-toxic, it does not support life and can, therefore, become a breathing hazard if it has collected. As it is heavier than air, it can typically collect close to the ground, in cable trenches or drainage systems, for example.Get price

What is sf6 gas Circuit Breaker? Construction, Working Principle

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.Get price
