摘要
为研究±1 100kV直流线路合成电场和离子流密度分布规律,采用Deutsch假设计算线路周围的空间合成电场和离子流密度,分析±1 100kV直流线路合成电场和离子流密度随导线对地距离、极间距、分裂间距及分裂数等参数变化时的分布规律。结果表明:合成电场和离子流密度随对地高度的增加而减少;合成电场和离子流密度在分裂间距取350mm达到最小;合成电场和离子流密度随分裂数的增加,减小趋势非常明显。
To research the distribution of total electric field、ion current density around ±1 100 kV UHV DC transmission lines,total electric field and ion current density are analyzed with Deutsch assumptions.And the impacts of the clearance to ground,the Space between Polar Conductors,the split pitch and the number split of transmission lines are analyzed.The results show that total electric field and ion current density decrease with the clearance to ground.that Total electric field and ion current density are minimum when the separation distance of the split pitch of transmission lines is 350 mm.And when the number split of transmission lines increase,the total electric field and ion current density is significantly reduced.
