Sulfr hexafluoride Circuit Breakers - Construction, Types and Working

The valve permits sulphur hexafluoride gas (Sulfr hexafluoride) gas at 14 kg/cm2 pressure from the reservoir to the arc interruption chamber. The high-pressure flow of sulphur hexafluoride gas (insulating gas) rapidly absorbs the free electrons in the arc path. It forms immobile negative ions which are ineffective as charge carriers.Get price

Analysis of Sulfur Hexafluoride in Air

A computer program controls the stream selection valve, the gas sample valve, and stores the data from the detector (via the electrometer). The operating conditions should not be changed without just cause. The SF. 6. results are sensitive to ECD temperature, flow rate, and quality of the carrier gas.Get price
