研究影响单相或单极分裂导线电场强度分布的因素,建立简化的电晕笼及分裂导线三维模型,运用ANSYS仿真分析,确定了起晕时子导线表面三维电场强度分布. 通过调整电压等级和分裂导线的几何尺寸,如分裂间距、子导线半径、分裂次数、电晕笼大小、导线排列形式等,来研究这些因素对测量段上最大场强的影响. 仿真结果表明,分裂导线表面最大电场强度随子导线半径的增大而减小,随分裂间距的增大而增大,随分裂数的增大而减小,随电晕笼边长的增大而减小. 电场强度分布的研究对解决电晕放电有重要的工程应用价值.

The factors influencing the electric field intensity distribution of single -phase or unipolar split conductor are stud-ied, and a 3D model of simplified corona cage and split conductor is established .The 3D electric field intensity distribution of sub-conductor surface is determined when dizzying by ANSYS .The impact of factors , such as split spacing , sub-conductor radius, split times, size of corona cage and wire arrangement , on maximum field strength of measuring section is also studied by adjusting the voltage level and the geometry size of split conductor .Simulation results show that the maximum electric field intensity of split conductor surface decreases as the radius of sub -conductor increases , it increases as the split spacing increa-ses, it decreases as the split times increases , and it decreases as the side length of corona cage increases .The research on e-lectric field intensity distribution has an important value for corona discharge in engineering application .
