高压架空输电线走廊周边楼房电磁环境研究

对城乡交界处220kV/110kV高压架空输电线走廊模式发生变化后的三种架设形式进行了测试分析。结果表明,220kV/110kV四回路杆塔形式对周边楼房室内外环境影响较大,当两者相距60m以外时,楼房室内外工频电磁场环境将有较大改善;居民楼建筑结构对工频电磁场有一定衰减作用,其中工频电场衰减较大,工频磁场衰减较小。建议适当控制高压架空输电线走廊与居民区的距离。

High pressure impracticable to transmit electricity line corridor peripheral building electromagnetic environment research

We test and analyse the three kinds of forms of erecting after the high pressure transmits electricity impracticably the line corridor mode changes in urban and rural areas intersection .Result indicate 220 kV/110 kV four return circuit pole tower forms exert a great influence on internal and external environment of room of peripheral building, when in the two beyond 60m apart, building room internal and external power-frequency electric magnetic field environment have heavy improvement; the building structure of residential building has certain function of decaying on the power-frequency electric magnetic field, the power-frequency electric field decays greater, the power-frequency magnetic field decays smaller. Advising proper to control high pressure impracticable to transmit electricity line corridor and distance of residential block.
