摘要
为获得110kV高压输电线的工频电磁场在居民住宅区内的分布情况,对邻近110kV高压线的典型居民住宅区内的电磁场进行实测,将实测值结合同线路在空旷地带的电磁场场强分布值和理论计算值进行比较.结果表明,住宅区的建筑对输电线产生的电场有较大的衰减效应,对磁场基本无影响;建筑物密度与电场场强有较密切的相关性,而与磁场场强没有相关性.
In order to get the distribution of power frequency fields produced by 110kV high-voltage transmission (HVT) lines in uptowns, electromagnetic field in the typical residential uptown near the 110kV HVT lines was measured; and the data with the distribution data of electromagnetic fields on the unoccupied regions are compared with the theoretically calculated data. The results show that the uptown building has significant attenuation effects on the electric fields produced by the lines; but no effects on the magnetic fields; and the building intensity has close correlativity with the intension of electric fields, but has no correlativity with that of magnetic fields.
