摘要
应用有限元法计算分析了500kV线路绝缘子的电压分布。计算模型充分考虑了绝缘子、导线、杆塔以及周围环境因素的影响,按照彼此的实际尺寸建模,计算结果给出了500kV线路绝缘子带均压环和不带均压环时的电压分布。这种方法可为输电线路用绝缘子的优化设计提供有效的计算工具。
The finite element method is presented for calculating the voltage distribution along the 500kV line insulators.The 3D models have set up according to the real dimensions of the insulator,conductor and tower,taking the most account of the influences between each other.The results show the voltage distribution of the 500kV line insulators with and without grading strings.So it can be used as an effective measure for optimal design of the line insulators.
