Protection and Switchgear - SlideShare

Sep 06, 2015 · sf6 gas CIRCUIT BREAKERS It contains an arc interruption chamber containing sf6 gas gas. In closed position the contacts remain surrounded by sf 6 gas at a pressure of 2.8 kg/cm2 . During opening high pressure sf6 gas gas at 14 kg/cm2 from its reservoir flows towards the chamber by valve mechanism. Sulfr hexafluoride rapidly absorbs the free electrons in the arc path to form immobile negative ions to build up high dielectric strength. It also cools the arc and extinguishes it. After operation the valve is closed by theGet price
