智能电表作为采集电量的主要装置,其高可靠性和长寿命尤为重要。可靠性预计是一种定量地评价智能电表的可靠性的有效手段,也为智能电表设计改进提供参考。 开展预计的关键是可靠性标准的选择,对常用的预计标准的原理,预计过程,优缺点进行了初步介绍。选取三种标准对某单相费控电能表进行可靠性预计,综合分析比较结果,GJB/Z299C标准的失效率远高于其他标准近乎两倍。
Abstract
As the main device for collecting electricity, the high reliability and long life of smart meter are particularly important.Reliability prediction is an effective means to quantitatively evaluate the reliability of smart meters and also provides a reference for the design improvement of smart meters.The key to carry out the prediction is the selection of reliability standard. The principle, process, advantages and disadvantages of the commonly used prediction standard are introduced.Three standards were selected to predict the reliability of a single-phase fee-controlled watt-hour meter. Through comprehensive analysis and comparison, the failure rate of GJB/Z299C was nearly twice higher than that of other standards.
