Questions about sf6 Regeneration

SF6 analysis – CEI EN 60480. SF6 is a chemical formula of an inorganic compound which corresponds to sulphur hexafluoride. It is an odourless, colurless, non-flammable, non-toxic gas which is five times denser than air. It doesn't easily dissolve in water, but is soluble in apolar, organic solvents. When SF6 is inside the electronic arc it can be contaminated by other products in a state of decomposition.

    Nov 15, 1995 · This leads to molecular regeneration factors, x, of less than 0.20 at all temperatures. This result indicates that SF6 is primarily converted to unknown neutral species upon recombination with positive ions (Reaction (2b)) and that less than 20% of the SF6 molecular anions are converted back to SF6.

  • SF6 Gas Recovery and Filling Device | YUNENG

    SF6 gas is a good electrical insulator. We have found that using SF6 gas in switchgear is more effective than relying on air or vacuum to achieve dielectric functions. SF6 gas not only provides insulation, but also provides stable operation at normal pressure levels that cannot be provided under vacuum. That is, SF6 gas has a high greenhouse effect.

  • MV Vacuum Circuit Breakers compared to SF6 Circuit Breakers

    SF6 gives a 'softer' switch than vacuum and therefore is not as big a mechanism for generation of transients. Vaccum is almost a perfect breaking medium and does not require regeneration of the dielectric during arc extinction. Contact travel is therefore shorter (less energy from the mechanism) and there are fewer parts.
