磁场作用下接地极雾化电晕放电荷电的研究

摘要

The influence of magnetic field on corona onset voltage was studied in the earthed atomizing corona discharge, and the charging mechanism was studied in earthed atomizing corona discharge under magnetic field. Eventually, the charging mechanism of earthed atomizing discharges under magnetic field was analyzed. The results show that the corona onset voltage of the earthed atomizing corona discharge is decreased because the magnetic field is used, and the charging efficiencies is enhanced by magnetic field. But the influence on the diameter of water drops was not obvious. In addition, the minimum values of discharge currents are exist in the earthed atomizing corona discharge when the magnetic field is used or not.%研究了磁场对接地板雾化电晕放电起晕电压的影响,以及在磁场情况下接地板雾化电晕放电的荷电机理,分析了磁场对雾化液滴粒径的影响.结果表明:磁场的应用使接地板雾化负电晕放电的起晕电压更低,使接地极雾化电晕放电的荷电效率增加；对液滴粒径的影响不大；无论是否存在磁场的作用,接地板雾化电晕放电均存在最小的起晕电压.
