超高压输电线路分裂导线表面电场计算及其特性分析

Calculation and Characteristic Analysis of Surface Electric Field Intensity of Bundled Conductors for EHV Transmission Lines

采用偶极子法,计算超高压输电线路分裂导线表面电场强度,进而分析导线对地平均高度、导线布置方式、分裂间距、相间距、分裂数、子导线截面、相序等因素对分裂导线表面最大电场强度影响的规律和特点。

The surface electric field intensity of bundle conductors for EHV transmission lines was calculated based on the dipole method. The impact of some factors, such as the average height of lines to ground, layout, bundled distance, distance among phase, number of bundles, cross-sectional area of bundles, phase sequence and so on, on the surface electric field inten- sity of bundle conductors were analyzed and discussed.
