| 摘 要： | 研究了非均匀电场中的静态模拟气固两相体放电的击穿、起晕特性及固相物介电常数、占空比、放电间隙、电压极性和种类对击穿电压与起晕电压的影响。结果表明:实验范围内,正极性大占空比时,随放电间隙的增加,两相体的起晕电压逐渐低于空气的起晕电压。正极性和交流电压下,两相体的击穿电压比空气高。

| Abstract: | The paper aims at the breakdown and corona characteristics of the two-phase mixture of gas and solid in the non-uniform electric field. The effect of permittivity of solid dielectrics, volume ratio of solid dielectrics, discharge gap, voltage polarity and voltage type on breakdown voltage and corona onset voltage is studied. The results shows that with positive DC voltage, the corona onset voltage of the two-phase mixture became lower than that of air at the same temperature and pressure in the experimental scope when the discharge gap is increased. With positive DC voltage or AC voltage, the breakdown voltage of two-phase mixture is higher than that of air. |
