  • The effects of moisture and gaseous additives on SF6 recovery

    Oct 27, 2005 · The obtained recovery curves show distinct phases as for pure SF 6. The influence depends on the gaseous additive nature and its proportion to the gaseous mixture. The presence of water vapor (humidity) in the breaking chamber is proved to be a degradation agent of the SF 6 insulating and recovery properties. Both dielectric and post‐arc recovery studies show that the gas dielectric strength reduces with the increment of the humidity concentration.

  • SF6 recovery - DILO

    SF 6 gas recovery and re-use. Although SF 6 is an excellent insulating and quenching medium it is very important to know that. SF 6 is a fluorinated gas (F gas) with the highest global warming potential. It is one of the six gases subject to monitoring under the Kyoto protocol. Relating to the greenhouse effect, 1 kg of SF 6 corresponds to a GWP value of more than 22,800 times higher than that of CO 2.

  • SF6 gas handling - DILO

    A service cart enables the recovery of the SF 6 gas from a gas compartment to a final vacuum of < 1 mbar. Thereby the gas flows automatically via dry and particle filters which effectively adsorb decomposition products and moisture from the gas. During the gas recovery process the SF 6 is stored either in gaseous or in liquid form. Furthermore, the air is evacuated from gas compartments after maintenance works.
