220kV变电站电磁辐射监测及防治措施

为了研究220 k V变电站电磁辐射的分布情况,对典型220 k V变电站进行监测与分析。监测结果表明,电磁辐射随着与辐射源距离的增大有明显的衰减,工频电磁场达40 m处时已接近环境背景值。据此,针对变电站电磁辐射的影响因素提出了防控措施,将电磁辐射影响降到最低。

In order to study the electromagnetic distribution of 220 kilovolt transformer substation, the monitoring and analysis were performed for a typical one. The result showed that electromagnetic radiation obviously decreased with the distance increasing from the radiation source, and it was close to environment background value when the power frequency electromagnetic fields reached 40 m. So, the prevention measures were proposed for the impacts of electro- magnetic distribution of transformer substation, which could minimize the impacts of electromagnetic radiation.
