摘　　要：现有智能电能表可靠性寿命试验周期长,且尚未形成较为系统完善的方案。利用Peck温-湿模型和可靠性理论技术,针对现有智能电能表可靠性寿命试验周期长且缺乏系统完善的问题,进行了分析和设计。从应力选择、参数模型、试验时间等多个方面入手,完成试验方案的设计。统计记录试验失效数据,基于可靠性理论与Peck温-湿模型计算得出平均无故障工作时间(MTTF),进而得到智能电能表的寿命数据。通过试验发现了电能表可靠性设计方案、元器件等方面存在的缺陷,进一步验证智能电能表的可靠性是否满足要求。The reliability life test cycle of existing smart energy meters is long,and a relatively systematic and comprehensive plan has not yet been formed.Based on the Peck temperature-humidity model and reliability theory technology,this paper analyzed and designed the problems of long reliability life test cycle and lack of system perfection of existing smart watt-hour meters.The design of the test scheme was completed from many aspects such as stress selection,parameter model,and test time.The test failure data was statistically recorded,and the mean time between failures(MTTF)was calculated based on the reliability theory and Peck temperature-humidity model,and then the life data of the smart watt-hour meter was obtained.Through the test,the defects in the reliability design scheme and components of the electric energy meter were found,and the reliability of the smart electric energy meter was further verified to meet the requirements.
