摘要:

根据最新的《单相智能电能表(2020版)通用技术规范》要求,智能电能表整表的使用寿命应大于等于16 a。智能电能表计量电阻的安全可靠运行直接关系到智能电能表计量的准确性。考虑运行环境温度的影响,对智能电能表计量采样电阻采用加速退化试验,评价其可靠性。为新标准下智能电能表可靠寿命的评估与提升提供了基础,建立的模型能够预测实际工况下的计量电阻使用寿命。

关键词: 智能电能表, 计量电阻, 加速退化试验, 可靠寿命

Abstract:

According to the latest Single-Phase Smart Electricity Meter (2020 Edition) General Technical Specification, the service life of the smart electricity meter should be no less than 16 years.The safe and reliable operation of metering resistor of smart electricity meter is directly related to the accuracy of metering precision of smart electricity meter.Considering the influence of ambient temperature in the operation of smart electricity meter,the accelerated degradation test on the metering and sampling resistor of smart electricity meter is conducted.The reliability of the metering resistor of smart electricity meter is evaluated.The results provide a basis for the evaluation and improvement of the reliable life of smart electricity meter under the new standard, and the established model can predict the service life of metering resistor under the actual working conditions.

Key words: smart electricity meter, metering resistor, accelerated degradation test, reliable life
