摘要/Abstract

摘要： 为有效解决邻近高压输电走廊居民楼工频电场超标问题，在有限元计算基础上，研究了不同屏蔽方式与其空间架设位置对工频畸变电场屏蔽的影响。通过畸变电场的仿真计算，深入分析屏蔽方式及其架设位置与屏蔽效能的关系，提出通过优化屏蔽设备的空间架设位置提高屏蔽效果的新思路。并综合考虑屏蔽效果和屏蔽成本，对110~1 000 kV 4个电压等级高压输电线路工频电场屏蔽方案进行设计。研究表明:通过合理选择屏蔽方式和优化架设位置，可大幅度提高屏蔽效能，对工频电场具有良好的屏蔽效果，对降低输电工程的环保成本具有重要意义，而不合理架设屏蔽设备则会使电场环境发生恶化。

Abstract: In order to solve problem of high power frequency electric field in residential buildings caused by nearby high voltage transmission corridor, shielding effectiveness of different shielding methods and their space construction are studied based on finite element calculation. Through simulation calculation of distorted electric field, the relationship between shielding method and effectiveness is analyzed. A new method to improve shielding effect is proposed by optimizing space construction model. The power frequency electric field shielding schemes for four voltage level high voltage transmission line, ranging from 110 kV to 1 000 kV, are designed with consideration of shielding effect and construction cost. The research shows that shielding effectiveness could be improved greatly by reasonable selection of shielding method and optimized mounting position. This is very important for reducing environmental cost of transmission project.

Key words: power frequency distorted electric field, erection position, electric field shielding, shielding line, residential buildings
