两种电晕放电特性比较研究

Comparative study on electric field characteristics of two corona discharges

为明确2种不同电源的电晕特性,对恒压电源和脉冲电源形成的电极对,通过控制变量法进行了2种电晕放电的电场特性及除尘性能的比较研究。实验结果表明:相同工况下,脉冲电晕放电的击穿电压和起晕电流都高于恒压电晕放电,其产生的平均电子密度高,使得粉尘去除效果略好,且除尘性能稳定,产生的副产物O3量少。

In order to clarify the corona characteristics of two different power supplies,the electric field characteris-tics and dust removal performance of two corona discharges were compared by Control variates for electrode pairs for-med by constant voltage power supply and pulse power supply.The experimental results show that under the same working conditions,the breakdown voltage and corona starting current of pulse corona discharge are higher than those of constant voltage corona discharge.The high average electron density generated by pulse corona discharge makes the dust removal effect slightly better,and the dust removal performance is stable,and the amount of by-product O3 generated is less.
