中文摘要：

本文分析了高压输变电设施对周围环境的电磁影响,梳理总结了国际、国内工频电场的限值标准情况。从防止电磁场环境影响、国际权威组织和部分发达国家的限值比较以及促进经济发展等方面详细分析了我国居民区工频电场限值的合理性。实践证明,我国居民区工频电场以4 k V·m-1作为限值是合理可行的。

英文摘要：

This article analyses the electromagnetic impact on the surroundings of high voltage transmission and transformation power facilities,summarizes international and domestic limit criteria of power frequency electric field. It detailedly analyses the rationality of the power frequency electric field limit in China＇s residential areas from 3 aspects,including preventing environmental impact from electromagnetic field,comparing with the limits of authoritative international organizations and some developed countries,promoting economic development. Experience has proved that it is reasonable and feasible to adopt 4 k V·m-1as power frequency electric field limit forour residential area.
