220kV高压输电线路的工频电磁场和无线电干扰污染

Pollution of electro-magnetical fields and radio disturbed fields of 50 Hz-220 kV high tension line

为获得 2 2 0 k V输电线路临近民房时的工频电场、磁场及无线电干扰污染状况 ,对 2 2 0 k V输电线路邻近居住区域工频电磁场强度及无线电干扰场强的分布进行实测 ,结合工频电磁场的有关国家标准 ,作出定性分析 ,认为 2 2 0 k V输电线路附近的电磁场对人们的健康不会产生有害影响 ,但暂态电击场强限值以3k V/m为宜 .

To get the pollute conditions of electro magnetical fields and radio waves near the high tension line in resident district.Measure were taken by the authors on the distributions of the intension of electro magnetical fields and radio disturbed fields. The qualitative analysis according to the national standards of china about electro magnetical pollution was then presented. The results showed that the electro magnetical fields did not gave serious damage to inhabitant near the high tension line, the limit intension of transient electronic fields should be lower than 3 kV/m.
