摘要
本文简要地总结了交流500kV线路跨越和邻近民房处工频电场、无线电和电视干扰的现场实测结果。工频电场实测结果表明:适当提高导线对地距离,并在房屋周围采用简易屏蔽措施后,500kV线路少量跨越民房是允许的。实测值和用静电感应模拟试验的结果一致,这说明用模拟来预测复杂结构房屋周围及屋顶电场分布所得结果是可信的。
This paper presents briefly the field measurement of power frequency electric field, radio interference and television interference near houses strided over by 500kV transmission lines. The results show that from the electrostatic induction point of view 500kV transmission lines striding over houses is permissible by appropriately increasing the height of conductors and taking some simple shielding measures to reduce the power frequency electric field. Since the results obtained from field measurement exhibit good agreement with that from model experiment, conclusion can be drawn that to predict the electric field distribution near the houses and on the roof by model experiment are reliable.
