摘　　要：为了评估拆回智能电能表的剩余寿命,设计了一种适用于拆回智能电能表的剩余寿命预测方案。首先对拆回智能电能表进行分拣、校验;设计拆回智能电能表加速寿命试验方案;对满足加速寿命试验条件的拆回智能电能表进行加速寿命试验;基于分组数据,求解出智能电能表剩余寿命的点估计及不同置信概率下的置信下限,对评估智能拆回智能电能表的剩余寿命及拆回智能电能表的再利用提供理论依据。In order to evaluate the remaining life of the replaced smart meters,a remaining life prediction scheme for the replaced smart meters is designed.Firstly,the replaced smart meters sorted,checked and accelerated life test scheme is designed.Secondly,the accelerated life test is carried out for the smart meters that meet the accelerated life test conditions.Based on the grouped data,the point estimation and the lower confidence limit under different confidence probability of the remaining life for the smart meters solved.It provides a theoretical basis for remaining life prediction and the reuses of the removed smart meter.
