| 摘 要： | 高压架空线路日益集中，研究两列及多列线路间重复区域的辐射重影问题对于电磁环境辐射研究具有现实意义。利用电磁辐射分析仪PMM8053B与工频电磁场探头EHP-50C，对220kV双分裂水平排列的线路进行电场强度、磁感应强度实际测量，测量结果表明辐射重叠区电场强度较大，电场最大值4．275kV／m高于国家环保推荐标准。应用改进等效电荷法计算电场强度、磁感应强度，并通过Matlab对改进等效电荷法计算结果与实测结果进行比较，两结果非常吻合，可为电磁辐射重影的分析提供参考意见。

| Abstract: | The overhead transmission lines have become centralized gradually and study on radiation echo of repeated areas between 2-row and multiple row lines has practical significance to electromagnetic environment radiation.Using the electromagnetic radiation analyzer PMM8053B and power frequency probe EHP-50C,the distribution of power frequency electric intensity and magnetic field intensity under 220 kV transmission lines were measured.The measured results indicate that electric field strength at radiation echo ... |
