摘要
为探讨电晕放电机理,用PC数据采集系统测量了在不同电压不同间隙距离下尖板电极的交流电晕放电,得出了单个工频不同半周放电的特征以及和相位的对应关系。通过改变电极形状,测量了单个放电脉冲的时域波形并且变换到频域下进行了分析,结果显示尖端场强增大时,对应放电的频谱分布变宽。
AC corona pulses in air in a point-plate electrode system are analyzed in the paper. As a function of phase angle the pulse distribution at various voltages is measured by computer-aided measuring system. Electromagnetic spectrum radiated from discharge in different electrode configuration such as point-plate and needle-plate is also analyzed by transforming the signal of discharge in time domain to frequency domain. The results of analysis show that the spectrum of discharge is broadened with the increasing of electric field intensity around the point.
