通过用两种磁场形式影响负电晕放电,研究了磁场对负电晕放电不同区域的影响。研究表明:磁场的应用可改变电晕区的放电强度,增加放电电流;磁场对荷电区的影响并不能改变放电电流的大小,揭示了放电电流增加的原因;磁场的应用加强电晕区内的电场强度,所以磁场的应用可使负电晕放电的起晕电压降低。
通過用兩種磁場形式影響負電暈放電,研究瞭磁場對負電暈放電不同區域的影響。研究錶明:磁場的應用可改變電暈區的放電彊度,增加放電電流;磁場對荷電區的影響併不能改變放電電流的大小,揭示瞭放電電流增加的原因;磁場的應用加彊電暈區內的電場彊度,所以磁場的應用可使負電暈放電的起暈電壓降低。

By using two forms of magnetic field to have an effect on negative corona discharge ,the influence of magnetic field on different inter-electrode area of corona discharge was studied .The research showed that the charging intensity is changed and the discharge current is increased when the magnetic field is applied to the corona zone .But the discharge current is not changed when the magnetic field is applied to the charging region .This well explained the reasons for the increase of the discharge current .Meanwhile ,the research shows that the onset voltage of negative corona discharge is decreased when the magnetic field is applied .The main reason is due to that the electric field intensity of the corona region is enhanced when the magnetic field is applied .
