Inhibition Effect of Solid Products and DC Breakdown Characteristics of the HFO1234Ze(E)–N₂–O₂ Ternary Gas Mixture

HFO1234ze(E) is an environmentally friendly SF6 substitute gas with prominent application potential. To suppress the generation of solid decomposition products, which may cause great hazards to gas–solid insulation strength, a mixing scheme screening method based on reactive force field (ReaxFF) molecular dynamics (MD) simulation was innovatively proposed. The results show that inhibitory effect O2 formation products better than those CO2 and CF4. Further study shows when accounts for 3.33% mixture, precipitate content reduced by 48%. experimental can inhibit more 50%. Besides, compared HFO1234ze(E)-N2, DC breakdown voltage HFO1234ze(E)-N2-O2 slightly increased, dispersion degree continuous drop rate are decreased. This work gives feasible solution suppression provides efficient solving similar problems insulating in C/F/O/N systems.
