机车车辆蓄电池端口传导骚扰测量的不确定度评定分析

The Uncertainty Evaluation Analysis on Conducted Disturbance Test of Battery Port in Rolling Stock

在阐述传导骚扰测量不确定度评定意义的基础上,针对机车车辆蓄电池端口传导骚扰测量中广泛使用V型人工电源网络的情况,逐一分析传导骚扰测量不确定度评定的影响因素,确定各个影响因素适用的数学模型,得出不确定度评定的计算公式。分析如何用不确定度评定结果对测试数据的标准符合性做出判定。

On the basis of expounding the evaluation significance of the uncertainty of conducted disturbance test,aiming at the situation that V-artificial power network is widely used in the conduced disturbance test of the battery port of rolling stock,the influencing factors of the uncertainty evaluation of conducted disturbance test are analyzed one after another,the applicable mathematical model of each influencing factor is determined,and the calculation for mula of the uncertainty evaluation is obtained.It analyzes how to use the uncertainty evaluation results to determine the standard compliance of test data.
