摘要
针对输电线路的电压等级、塔形、导线对地高度、分裂导线形式等种类和特点,基于Ansoft有限元分析软件,对输电线路所在空间进行建模,研究交流输电线路电场分布规律及影响因素。依据相应的电磁环境控制指标,给出不同影响因素下输电线路对地距离,建立考虑工频电磁场环境的输电线路布置方法,以期为项目环评、输电线路设计提供参考和借鉴。
The electromagnetic field distribution of power transmission lines are modeled and analyzed based on Ansoft in the light of voltage level, tower shape, lead to ground distance, split conductor form. According to reiated control index of electromagnetic index, lead to ground distance is proposed under different factors. It is suggested to consider transmission line arrangement under electromagnetic environment for supplying reference to project environment assessment and transmission line design.
