| 摘 要： | 针对电气铁路支撑绝缘子污闪情况,分析了在列车风环境下,高速机车间歇列车风环境对支撑绝缘子表面积污状况的影响。分析表明,在列车风环境下,绝缘子两端部积污明显,应以端部积污状态来确定清扫频率;在输电线路闪络模型的基础上,结合在间歇性列车风影响下支撑绝缘子闪络的特点,分析了风场环境及风速对污闪的影响,修正了闪络模型。

| Abstract: | For the supporting insulator pollution flashover,the influence of the intermittent wind condition of high speed train on the pollution accumulation on supporting insulators surface is analyzed.The results shows that under the aerodynamic force,the pollution accumulation is obviously on both ends of the insulator,the cleaning frequency should be determined according to the pollution condition by the ends.Based on the flashover model applied in transmission line and the characteristics of the flashover of supporting insulators under the effect of the intermittent aerodynamic force near high -speed trains,the influence of wind field environment and wind speed on flashover on the pollution flashover are analyzed,and the flashover model is corrected. |
