Limiting Sulfr hexafluoride Gas Emissions by Optimization of Design and

6 is introduced via a permanent valve (like STS type – Siemens uses a clenched tube). The equipment are "Helium Tight" tested, and, in case of leak, the leakage point is detected with SF 6. Then the apparatus is filled with SF 6. The counter, placed next to the gas valve gives the mass (weight at sea level) of SF 6 included in the switchgear. Then this mass is hand written on the CAPIEL label affixed to the circuitGet price

Protection and Switchgear - SlideShare

Sep 06, 2015 · gaz sf6 CIRCUIT BREAKERS It contains an arc interruption chamber containing Sulfr hexafluoride gas. In closed position the contacts remain surrounded by Sulfr hexafluoride gas at a pressure of 2.8 kg/cm2 . During opening high pressure gaz sf6 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
