摘　　要：【目的】为了分析交流架空输电线路下工频电场强度的分布规律。【方法】本研究选取某条拟建110 kV输电线路为研究对象,采用等效电荷法,通过Excel软件,对多种不同架设方式的线路下方的工频电场强度进行理论计算和分析。【结果】研究发现,不同架设方式,线路下方的工频电场强度规律有所不同,但总体上呈现随距离增加而衰减的趋势。【结论】工频电场强度的预测计算,可为输变电工程的环境影响评价工作和设计工作提供参考。[Purposes]To analyze the distribution law of power frequency electric field strength under AC overhead transmission lines.[Methods]In this study,a proposed 110 kV transmission line is selected as the research object.By using the equivalent charge method and Excel software,the power frequency electric field strength under the line under various erection modes is theoretically calculated and analyzed.[Findings]The power frequency electric field strength under the line varies with different erection methods,but it tends to decline with the increase of distance.[Conclusions]The prediction and calculation of power frequency electric field strength can provide reference for the environmental impact assessment and design of power transmission and transformation projects.
