The c-C4F8 gas is considered to have great potential as a gaseous medium for use in gas-insulated equipment due to its good insulation properties and its relatively low greenhouse gas potential (Global warming potential, GWP) relative to SF6. In this paper, the breakdown characteristics of c-C4F8/N2 gas mixtures are explored through the experimental and theoretical calculations and the influence of a small amount of oxygen in the mixtures is discussed. The breakdown tests were conducted under AC voltage. With the mixing ratio of c-C4F8 at 15%, the breakdown voltage of different oxygen contents was tested at 0.15 MPa. At the same time, the self-recovery performance of gas mixture was tested by several times breakdown test, and the breakdown voltage of mixed gas was calculated according to the Townsend self-sustaining discharge condition. The results show that the addition of O2 significantly reduced the breakdown voltage of the c-C4F8/N2 mixed gas, and the self-recovery characteristics of the mixed gas containing 3% O2 are significantly lower than that of the c-C4F8/N2 without O2. The calculation results of breakdown voltage are consistent with the test results. It is considered that the content of oxygen in the mixed gas of c-C4F8 should be strictly controlled.The c-C4F8 gas is considered to have great potential as a gaseous medium for use in gas-insulated equipment due to its good insulation properties and its relatively low greenhouse gas potential (Global warming potential, GWP) relative to SF6.
