摘要
通过电磁场有限元软件ANSYS仿真,构建了绝缘子三维模型,分析绝缘子表面导电颗粒长度以及不均匀系数对闪络电压的影响。仿真结果表明,闪络电压随着颗粒长度的增加而减小,电场强度随着颗粒长度的增加有饱和的趋势。仿真结果与实验结果有较好的对应关系。
Using finite element program ANSYS for simulation electromagnetic field, a three- dimensional model of insulator was constructed. Based on this model, the effect of the length of conductive particle and the uneveness factor of flashover voltage was analyzed. The simulation result indicates that flashover voltage has a decrease tendency with increasing of particle length, electric field strength had a saturation tendency with increasing of particle length. The simulation results are consistent with experiments.
