摘要/Abstract

摘要： 绝缘子自然积污情况下，表面污秽在积污过程中其上下表面盐灰密、颗粒粒径、表面元素成分和颗粒形貌发生变化。以江苏徐州地区架空输电线路绝缘子串为对象，对悬挂绝缘子上、下表面的盐密和灰密变化及绝缘子表面污秽理化特性进行了测试分析，探讨了徐州地区绝缘子表面污秽特性。结果表明：绝缘子表面的盐灰密值与天气状况相关，绝缘子积污在2月份达到最大值，且与周边主要污染源存在较大关系；在徐州水泥污秽地区，绝缘子上表面沉积污秽度较大，下表面污秽度相对较小，不同环境下绝缘子表面积污物粒径、成分及含量均存在较大差异。其结论可为水泥污秽区绝缘子积污预警及日常运行维护提供参考。

Abstract: In the case of natural fouling of insulators, the salt ash, the particle size, the surface elemental composition, and the particle morphology of the upper and lower surfaces would change during the process of surface contamination. In this paper, the insulator string of overhead transmission lines in Xuzhou, Jiangsu Province is taken as an object to test and analyze the physical and chemical characteristics of the surface contamination of suspension insulator insulators. Meanwhile, the surface contamination characteristics of insulator in Xuzhou area are discussed. The key findings are as follows:the insulator equivalent salt deposit density and non-soluble deposit density are related to weather, and the dirt accumulation achieves maximum value in February, which has a great relationship with the main surrounding pollution sources. In the cement polluted area, Xuzhou, the filthy degree on the upper-surface is larger, the filthy degree on under-surface is relatively smaller; The particle size, composition and content of the fouling on the surface of insulator differ greatly under different environments.. Conclusion can be used as reference basis of insulators' operation and maintenance in cement polluted area.

Key words: insulator, cement pollution area, accumulation characteristics, ESDD, NSDD
