摘要
笔者主要研究分析了线路绝缘子表面有雨滴分布时电场分布情况。利用有限元分析软件ANSYS构建了线路绝缘子有限元计算模型。通过对线路绝缘子模型仿真分析,首先得出了伞裙表面没有雨滴分布时伞裙上表面电场分布情况。接着通过仿真分析得出了雨滴位置、大小、电导率等因素对绝缘子表面电场的影响规律。最后通过对前述分析归纳总结,提出相应的优化建议,以提高电力系统运行的可靠性和安全性。
This paper mainly studies the distribution of electric field of line insulator when there is raindrop distribution on sheds surface. Using finite element analysis software ANSYS to construct the finite element model of line insulators. By the simulation analysis on model of line insulators, firstly, the distribution of electric field on the surface of the umbrella skirt is obtained without raindrop, then the influence of the location, size and electrical conductivity of the rain, on electric field distribution of the insulator is analyzed. Finally, by summarizing the above analysis, the corresponding optimization suggestion is put forward to improve the reliability and security of power system operation.
