摘　　要：变电站高压设备的上层有相互交叉的带电导线,下层有各种形状高压带电的电气设备以及设备连接导线,在它们周围空间形成了一个比较复杂的高交变工频电磁场。同时各种500 kV电气设备、导线、金具、绝缘子串亦可能产生局部电晕放电,这些都可成为无线电干扰源。有关变电站电磁辐射影响文献报导较少,本文基于500 kV变电站建设,探析变电站周围工频电磁场、无线电干扰水平。In a 500 kV transformer substation, there are intersectional live wires on top of high - voltage equipment and con- nection wires in various shapes, which form a complex high -alternating power- frequency electromagnetic field in surrounding space. Meanwhile electrical equipment, conducting wires, hardware fittings, insulator strings may also produce partial corona dis- charge. All of these can become radio interference sources. Since there are little literatures regarding the influence of electromag- netic radiation in substations, this paper is based on the construction of a 500 kV substation via analyzing the power - frequency e- lectromagnetic field and radio interference level around transformer substation.
