Study on Arc Extinguishing Performance of DC C4F7N/CO2 Mixed Gas

IOP Conference Series: Earth and Environmental Science, 2021
Abstract The arc characteristic analysis of C4F7N/CO2, CO2 and SF6 gases with volume fraction of 10%C4F7N-90% under DC condition is studied. Firstly, based on the internal physical process of arc, a two-dimensional axisymmetric arc model of C4F7N/CO2, CO2 and SF6 gas was established and calculated.

Effect of aluminum particles on the insulating properties of C4F7N/CO2 mixed gas

AIP Advances
The C4F7N/CO2 mixed gas is most expected to replace SF6 in high-voltage power equipment, and the generation of free metal particles in gas-insulated equipment is unavoidable and highly susceptible to inducing insulation failures.

Decomposition characteristics of C4F7N-based SF6-alternative gas mixtures [PDF]

Journal of Applied Physics
C4F7N [2,3,3,3-tetrafluoro-2-(trifluoromethyl)propanenitrile]/CO2 gas mixtures are being developed as an eco-friendly electrical insulator to replace SF6, the most potent greenhouse industrial gaseous dielectric. However, recent studies have reported complicated and often conflicting decomposition pathways for C4F7N/CO2 gas mixtures, which has raised ...
