摘　　要：及时全面掌握电网积污水平是预防电网污闪事故的基础,通过绝缘子积污预测获取污秽水平是适应电网智能化的发展方向,但目前绝缘子积污预测的理论基础不够完善,预测准确性欠缺。文中以上述问题为出发点,对绝缘子积污的外部影响因素进行了分析,对基于大气环境成分、基于气象参数预测绝缘子积污的方法及其准确度、适用性进行了总结。结果表明,大气环境成分、气象参数对绝缘子积污有显著影响;目前基于大气环境成分的绝缘子积污预测尚无法实现饱和污秽度的预测,基于气象参数的绝缘子积污预测尚不能满足工程要求;综合大气环境成分、气象参数两方面数据的预测方法是实现绝缘子饱和积污预测的研究方向。The acquisition of the power grid contamination character is the basement for preventing pollution flashover, which obtained by insulator pollution prediction is the future development direction for adapting the power gird intellectualization. However, the insulator pollution prediction is still imperfect both for the- oretical base and test accuracy. Therefore, the article analyzed the external factors affecting insulator con- tamination. In further, the accuracy and the applicability of insulator contamination prediction method based on air environment composition or based on meteorological data were discussed. It is shown that the insulator contamination characters was both significantly related with air environment composition and mete- orological data. Presently the prediction method based on air environment composition could not calculate the saturate contamination value, the prediction method based on meteorological data were still not matured enough to be used for actual insulator contamination forecast. Method considering both air environment composition and meteorological data could be the future research direction for calculating insulator saturate contamination.
