摘要
进行了不同特性电源对同轴电极放电产生离子的实验研究,结果表明:高频高压电源所产生的离子浓度为107个/cm3,直流电源所产生的离子浓度为104个/cm3,工频和脉冲电源产生的离子浓度分别为105个/cm3和104个/cm3.由此得到高频高压电源所产生的离子浓度高于直流、工频和脉冲电源的结论.同时分析了电晕放电产生的离子浓度与电源的频率、极性以及波形之间的关系.并提出了一种大气压下区域性高浓度离子产生的方法.
The experiment research on the ion produces by different characteristic high-voltage corona discharge in coaxial electrode system is investigated in this paper. Conclusions are drawn as follows: the high-frequency power supply can produce the concentration of ion is 10~4(uni/cm^3), and the direct power, 50 Hz power, pulse power can produce ion with 10~4(uni/cm^3) 10~5(uni/cm^3) 10~4(uni/cm^3) respectively. The result of high-frequency power can produce higher ion than the others is obtained. And meanwhile the relationship between the ion concentration with power frequency, polarity, and the waveform is discussed. At last a novel method which produces high range concentration ions in air atmospheric pressure is presented.
