摘要
在总结了国内外特高压输电线路电磁环境研究结果的基础上,文章结合我国特高压输电线路初步设计的主要塔型和导线型号的电磁环境参数的计算分析,提出了1000kV级交流榆变电工程电磁环境对于工频电场、工频磁场、无线电干扰、可听噪声等参数控制指标的建议,如公众容易接近地区、线路跨越公路处的场强限值为7 kV/m,跨越农田的线路的场强限定为10 kV/m,无线电干扰设计值为55～58dB,可听噪声设计标准控制在55 dB以内等.
Based on summarizing the domestic and international research results of electromagnetic environment for UHV power transmission line, and combhaed with the calculation and analysis of electromagnetic environment parameters for major tower and conductor type of preliminary design of UHV power transmission line in China, the suggestions for parameter indexes control of electromagnetic environment for 1 000 kV power transmission and transformation project such as power frequency electric field, power frequency magnetic field, radio influence and audible noise were put forward. The suggestions in the area that public is close to easily show that the limited value of electric field intensity for the line of crossing highway is 7 kV/m, the limited value of electric field intensity for the line of crossing farm is 10 kV/m, the design value of anti - radio - influence is 55 - 58 dB, the design standard for audible noise control is in 55 dB etc..
