Abstract
In recent years, C5F10O (Perfluoro(3-methyl-2-butanone), as a potential substitute gas for SF6, has attracted extensive attention from researchers. C5F10O has high molecular freedom and strong energy absorption ability. Due to the high fluorine content in C5F10O gas, it has excellent insulation characteristics, more than twice that of SF6 under the same conditions. It is considered to be the most promising alternative gas for SF6. C5F10O mixed ratio insulating gas is a new type of environmentally friendly insulating gas, and its partial discharge statistical characteristics are rarely studied at home and abroad. In this paper, the statistical characteristics of partial discharge in C5F10O/N2 gas mixtures under extremely inhomogeneous electric field conditions are studied, and the characteristics of their statistical characteristics are analyzed. It is found that the addition of oxygen changes the partial discharge decomposition characteristics of the C5F10O/N2 gas mixture, degrades the partial discharge characteristics of the C5F10O/N2 gas mixture, making the more severe the electron dissociation, and increases the electric field distortion near the needle tip, thereby promoting the discharge on both sides of the sinusoidal voltage peak (around 270°).
