摘要
220kV电压等级的高压架空输电线路直接穿越人口密集区域、跨越民宅的现象日益增多。在对工频电磁场环境影响特点、工频电磁场屏蔽原理分析的基础上,结合高压输电线路走廊内民房建筑物内、外的环境工频电磁场现场监测数据,对民房建筑的工频电磁场屏蔽效果进行了分析和研究。
In recent years, more and more 220 kV high -voltage transmission lines directly through the densely populated region, or across the houses. On the basis of analyzing the characteristics of power frequency electro- magnetic field ,the principle of electromagnetic shielding ,and the monitoring data of civil buildings under a power line,shielding effects by typical buildings from the electromaqnetic field are analyzed and researched.
