摘要 为研究高压输电线路的电磁辐射,对黑龙江省220 kV和110 kV单、双回输电线路进行了监测,并对监测结果进行了分析。结果表明:高压输电线路工频电磁场强度随测点距离中心导线对地投影距离的增加而减少,电磁场强度随输电线路对地高度的增加而减少。据此,针对输电线路工频电磁场的影响因素提出了防控制措施,以期待治理输电线路电磁辐射造成的污染。 In order to study the electromagnetic radiation from high - voltage power transmission line, this paper introduces the monitoring process of the 110 kV and 220 kV single and doublecircuit transmission lines in Heilongjiang and analyzes the monitoring results, which show that the electric fields intensity and magnetic intensity of high - voltage power transmission line decreases when the distance between the center conductor andthe ground increases. On the basis of the result, this paper proposes protective measures in accordance with the influential factors of power frequency electromagnetic field to treat pollution of electromagnetic radiation from transmission line.
