摘要
为了保证输电线路的正常运行,220 kV耐张塔更换绝缘子串必须保证带电作业,随之而来的安全问题不可避免。文章基于三维电场的有限元法,计算并分析220 kV耐张塔更换绝缘子串带电作业时的人体电场。研究结果不仅可以了解带电作业时人体电场的分布情况,并且能够为日常带电作业的安全预防提供参考。
In order to ensure the normal operation of transmission line,strain tower 220 kV insulator string replacement operation must ensure hot-line work.The attendant security problems are inevitable.Based on the finite element method of three-dimensional electric field,calculation and analysis of strain tower to replace the 220 kV insulator string field live working body is given.The results of study not only analyze body electric field distribution in hot-line working,but also can provide a reference for safety precautions live daily operations.
