摘　　要：鉴于DD862型单相感应式电能表在使用中存有运行寿命与设计寿命差距的问题,故对其替代品单相感应式长寿命电能表提出了用其运行寿命误差曲线来直观观察其运行寿命以制定轮换周期的建议。为此,在论述单相感应式长寿命电能表运行寿命影响因素的基础上,确定了对实际安装运行的单相感应式长寿命电能表进行隔年跟踪抽测并绘出运行寿命误差曲线,从而考证其运行寿命的方案,该方案能精确地确定电能表的轮换周期,有效地保证了电能计量的精确度。In consideration of the difference between the actual service life and the design life of the single-phase induction kilowatt-hour meter type DD862, it is suggested that the service life of its substitute, the single-phase induction long-life kilowatt-hour meter, be observed visually through the curve of service life error, so as to determine the period of replacement. Based on the analysis of the factors influencing the service life of the single-phase induction long-life kilowatthour meter, a scheme is determined, which enables precise determination of the replacement period of the meter by conducting tracking and sampling test on the meter every other year and plotting the curve of service life error, thus effectively ensuring the accuracy of electric energy metering,
