摘要
针对绝缘子覆冰对电力系统的危害问题,以110kV复合绝缘子为例,对户外绝缘子的电位分布进行理论分析,介绍计算模型和网格划分情况,并结合计算结果,说明不同覆冰长度对绝缘子表面电位分布的影响程度。
In view of the problem of the ice on insulators in power system, with example of 110 kV composite insulator, the paper analyzes the potential distribution of outdoor insu- lator theoretically; introduces the calculation model and net- work division, indicates the influence on the potential distri- bution on the insulator surface with different ice covering length through the computation results.
