摘要

随着中国超高压线路不断扩展，输电线路对周围空间电磁环境及人员身体安全影响问题逐渐备受关注，当输电线路周围存在建筑时，在特殊环境中会存在建筑近区或人员活动区域电场强度超过国家标准限值的情况。目前工程建设中通常采用拆迁或架设屏蔽线的方式进行优化，但由于对电场超标的关键因素深入研究不够、改进方案针对性不足，改善提升效果欠佳。为解决实际工程电场超标的问题，文中构建输电线路电磁环境有限元分析模型，对输电线路周边建筑近区电场强度分布特性的影响因素开展深入研究，提出了电场分布改善方法及屏蔽线架设位置的优化方案，并验证了其有效性。

Abstract

With the continuous expansion of EHV lines in China，the impact of transmission lines on the electromagnetic environment of surrounding spaces and publich health safety has gradually garnered significant attention. In case of buildings around transmission lines，the electric field intensity in such sspecific environments as area close to the structures or spaces with human activity may exceed the limit set by China national standards. Currently，the common optimization methods in engineering cnstruction involve either demolition and relocationor the installation of shield wires. However，due to the lack of systematic and depth research on the key factors causing the electric field to exceed the standards as well as the low pertinence of the improvement scheme，the optimation effect is not satisfactory. For solving the problem of the electric field exceeding the standard in the actual projects，the finite element analysis model of transmission line electromagnetic environment is constructed to study deeply the influencing factors of electric field intensity distribution characteristics in the near area of buildings around the transmission line.The electric field distribution improvement method and the optimization schems of shield wire installation are propsoed and their effectiveness is verified.
