| 摘 要： | 为了研究电晕放电辐射场若干特性,首先进行了电晕放电时电晕电流的理论分析,研究了电晕电流的波形随电压变化情况。然后在采用针-板电极物理实验模型的基础上进行了电晕放电实验研究,分析了放电针上的充电电压对脉冲电流的影响,并确定了辐射场随传播距离的变化规律以及放电重复率随电压的变化情况。实验结果发现,当针为负极性时先发生放电,但正极性下先发生火花放电;电晕放电辐射场与距离成反比关系;放电重复率随着电压的增大而增大。

| Abstract: | In order to study the characteristics of fields radiated from corona discharge,firstly,the corona current is analysed theoretically,and the current waveform along with the change of voltage is studied.And then the needle-plate electrode is adopted to study the characteristics of corona discharge,the effect of charging voltage on discharging needle on pulse current is analysed,and the relation of radiation field and the propagation distance is determined,the discharging repetition rate as a function of the charging voltage is also discussed.The experimental results indicate that the corona discharge occurs first when the needle is negative, but the spark discharge occurs first when the needle is positive.The radiation field is in inverse proportion to distance, and the discharging repetition rate increases along with the increasing of charging voltage. |
