典型110kV变电站站界电磁环境现状分析

Analysis of the Electromagnetic Environments around the Typical 110 kV Transformer Substations

通过分析对比4种不同布置方式典型110 kV变电站站界电磁环境检测数据,得出目前110 kV变电站周围的工频电场强度和磁感应强度均远小于国家推荐的标准限值,即工频电场强度4 kV/m和工频磁感应强度0.1 mT。此外,变电站的构筑物对变电站工频电场的屏蔽效果显著,这给未来城市变电站的规划设计提供了有益参考。

By analyzing and comparing the monitoring data of the electromagnetic environments around four typical 110 kV transformer substations,we conclude that the power frequency electromagnetic field intensities are all far lower than the recommended limits（power frequency electric field intensity 4 kV/m and magnetic fiild intensity 0.1 mT） in the national standards.In addition,the shielding effect of the substation structures on power frequency electric field is remarkable.This study may provide a reference for planning and designing future transformer substation in city.
