SF6-alternatives process for sieyuan

2021-2-5During the ionization process, the electrons in the air molecules keep getting energy from the electric field. When electrons return from the excited state orbital to the original stable electron energy orbital, it releases energy in the form of corona, flash-over or spark discharge accompanied by ultraviolet radiation.

    In the text Line 64-68, One approach to reduce the emission of SF6 was to replace partial SF6 with other inert substances with lower GWPs. For example, SF6/N2 were selected. Although the dosage of SF6 decreased, the GWP of a SF6(10%)/N2 mixture by volume reached 8650 [9]. It was still unacceptable.Cited by: 7
