摘要
分析了智能电表的功能、结构和特点,介绍了电子产品可靠性预计的主要方法,在此基础上指出元器件应力法适合于预计智能电表的可靠性。接着以河南许继仪表有限公司的智能电表DDZY566C-Z为例,对智能电表的可靠性进行了预计,为设计方案的比较评价提供了比较科学的依据。
The function; structure and characteristics of smart meter were analyzed, and the main methods of reliability prediction for electronic products were introduced. On this basis, this paper pointed out that component stress method was a suitable method of reliability prediction for smart meter. Then it predicted the reliability of the smart meter named DDZY566C-Z made by XJ INSTRUMENT CORPORATION in Henan. It provided relative scientific basis for the comprehensive evaluation of designing scheme.
