| 摘 要： | 设计了一种可代替人工判断的绝缘子污秽等级辨识方法，并基于新标准IEC 60815-1：2001给出的盐密、灰密与现场污秽度的对应关系，开发一个绝缘子污秽度等级判定程序，利用采样点的盐密值和灰密值，以最小二乘法拟合污秽等级的分界曲线，来确定绝缘子的污秽等级。实践证明，该方法不仅提高了工作效率，而且准确性比人工判断要好。

| Abstract: | A new method for the insulator pollution grade judgement is designed to replace the manual judgement. A program for this method is developed based on the new standard of IEC 60815-1 ： 2001 that indicates the relationship between the insulator pollution grade and the equivalent salt / non-soluble deposit densit （ESDD/NSDD） data. With the program the pollution grade corresponding to the NSDD/ESDD data from sampling site is determined by fitting the division curve of pollution grades with least-squares procedure. Practice validated that this method works efficiently, and has better accuracy than the manual judgement. |
