摘　　要：首先根据现场统计数据分析了影响智能电能表可靠性的主要因素,选取对其影响较大的温度、湿度应力组合作为加速因子对智能电能表进行加速寿命可靠性试验。通过对电能表失效类型进行定义,制定了加速寿命试验的试验方案,对实验室条件下实现智能电能表的加速寿命试验进行了探讨。According to the site statistics, this paper analyzed main factors impacting smart meter reliability firstly. Then, it selected temperature and humidity stress combination as an accelerating factor which has significant impacts on reliability, to carry out reliability test of smart meter. Through defining failure types of smart meter, it formulated the scheme design methodology for the meter’ s accelerated life test, which discussed the accelerated life test under la-boratory conditions on the smart meter.
