电磁环境影响研究

摘要
阐述同塔多回超高压架空输电线路的电磁环境影响,按照不同相序排列方式对无线电干扰、工频电场、工频磁场进行分别计算,得出各种条件下的无线电干扰水平与电磁场强度,论述各种塔型及不同排列方式下电磁环境是否满足环保规程的要求。
With the improvement of living standards, people pay more and more attention to the electromagnetic environmental impact of overhead transmission lines. This paper describes the electromagnetic environment impact of multi-circuit UHV overhead transmission lines on the same tower. Radio interference, power frequency electric field and power frequency magnetic field are calculated separately according to different phase sequence arrangement. The level of radio interference and electromagnetic field intensity under various conditions are obtained. Whether the electromagnetic environment meets the requirements of environmental protection regulations under different tower types and different arrangement modes is discussed.
