摘　　要：随着输电线路电压等级的不断提高,输电线路电磁环境问题越来越受到人们的关注。结合实际工程,对同塔双回架设的750 kV输电线路的空间工频电场、导线表面场强及电晕损耗、可听噪声和无线电干扰进行了计算,并分析了相序排列方式和导线高度对上述电场综合环境的影响,对同塔双回架设的750 kV输电线路的设计提出了建议。With the continuous improvement of the voltage level of transmission lines,electromagnetic environment problems of transmission lines have received more and more attention.Based on the engineering practice,this paper calculates the spatial power frequency electric field,surface electric field intensity and corona loss,audible noise and radio interference of 750 kV transmission line set up by the double-circuit,and analyzes the influence of phase sequence arrangement and conductor height on the electromagnetic environment mentioned above,and puts forward some suggestions for the design of the double-circuit 750 kV transmission line.
