Abstract:

冲击电压标准波源是进行冲击电压量值溯源的关键设备,为了建立标准冲击电压测量系统,在全国范围内实现冲击电压量值传递需研制该设备,介绍了低阻抗冲击电压标准波源的理论分析、不确定度评定及其特性分析。冲击电压标准波源为小型的Max发生器,其电压峰值Up、波前时间T1、半峰值时间T2都可以根据脉冲形成回路的元器件参数计算得到。该标准波源的Up为10~1000V,T1为1.5439μs,T2为59.5005μs。输出波形参数Up、T1、T2的相对不确定度(包含因子k=2)Urel,Up=5×10-4、Urel,T1=4×10-3、Urel,T2=2×10-3。实际测量结果与理论计算值的偏差为-0.8‰~0.6‰,基本无极性效应。T1的偏差为-1.5‰~2.5‰,T2的偏差为-1.7‰~0.5‰。连续重复20次,最大相对标准偏差为2.7×10-4。1年之内各电压点峰值长时稳定性在0.3‰内。校准5kV标准电阻分压器(3.45kΩ),冲击刻度因数与频率响应试验结果相符,测量得到的时间参数与理论计算结果相符,表明该低阻抗冲击电压标准波源既可校核数字记录仪也可校准电阻分压器。与Strauss生产的Kal1000校准器进行比对,Kal1000的峰值偏差为-2‰~3‰,峰值偏差远大于所研制的标准波源。
