摘　　要：首先分析了接触器动态响应过程中触头运动参数不确定的产生原因和主要类型,以9台接触器的不确定度构成抽样样本,在此基础上提出整体批不确定度指标,并利用K-S小样本检验法估计整批产品不确定度的置信区间。通过实例计算9台样品的批不确定度点估计为4.870,在置信水平95%下批不确定度置信区间为(3.846,5.894)。提出批量产品的动态响应不确定性的评价方法,为用户选择动态响应一致性的电器产品提供理论依据,具有实际应用价值。The reasons and main types of uncertainty in the dynamic response of contactor were discussed in this paper. The lot uncertainty was proposed to evaluate the internal of the confidential overall products by using K-S small sample test, based on the uncertainty indicator of each single test product applying the fuzzy hierarchy comprehensive theory. The lot uncertainty point estimation value of 9 test products is 4.81, and the confidence interval is（3.846,5.894） under the confidence level 95%. The lot uncertainty indicator is practical for choosing the best electrical products.
