摘要

均匀升压法是绝缘子人工污秽试验的一种重要试验方法

通过对复合绝缘子污秽试验次数的统计特性分析

并经实例计算

在一定统计误差和置信水平下

估计绝缘子污闪试验所需的最少试验次数。均匀升压法的最小样本数与相对分散系数有密切关系

对于直流复合绝缘子污秽试验

最小有效样本数取10

2次

对于交流复合绝缘子

最小样本数取15

6次。

Abstract

Uniform increase voltage is an important test method of the artificial pollution test of insulator

According to the satistical characteristics analysis of pollution test times of composite insulator

under the certain accuracy standard and confidence level

the paper estimated the minimum sample amount of pollution tests needed for pollution flashover voltage of insulators by example calculation.The minimum effective sample size must be 10

2 times for d.c.composite insulator and 15

6 times for a.c.composite insulator.
