50hz SF6-alternatives process

May 28, 2020Even in the conditioning process of vacuum interrupters, the increase of the voltage strength is accompanied by 92 scatter, as is visualized in the left side of Figure 3.20. Furthermore, single break VCBs have a lower practical limit in rated voltage than SF6 CBs. For high voltage applications, multi-break solutions could overcome this limit.

  • A review on SF6 substitute gases and research status of

    Nov 01, 2018SF 6 gas is widely used in electric power apparatus as an insulation and arc-quenching medium. However, the application of SF 6 gas faces two serious problems, including the heavy global warming effect and high toxicity of its decomposition products. So, scholars committed to finding environmental-friendly alternative to SF 6 gas and the relevant research results have been obtained.Cited by: 12

    6 mins readAccording to these characteristics, CF 3 I has been a potential alternative to SF 6 as a new insulating gas. Due to its high boiling point of −22.5 &C and the formation of I 2 in pure CF 3 I, CF 3 I should be mixed with other gases with low boiling point, such as N 2, CO 2, O 2, air, CF 4, Ar, Xe, and He.Cited by: 7
