Abstract

As a traditional insulating gas, SF₆ has a serious greenhouse effect. At present, SF₆/N gas mixture, as an alternative to environmental protection, has good application prospects and attracts wide attention of scholars. In order to investigate the corona discharge characteristics of SF₆/N gas mixture under DC voltage, an experimental platform for needle-plane model corona discharge is built in this paper. The effects of N content on discharge characteristics of SF₆/N gas mixture are studied under the experimental conditions of 25 and 0.3MPa pressure. The development process of corona discharge in SF₆/N gas mixture is analyzed, and the variation of initial voltage and the main pulse characteristic parameters of gas mixture with different N content under negative DC voltage are measured. The results show that the corona discharge process in SF₆/N gas mixture can be divided into four stages. With the increase of N content, the initial voltage will decrease and the pulse repetition rate will increase. The rise time will not change with N content, the fall time and the pulse duration have no obvious regularity, and the pulse amplitude shows different trends under different N content.
