高干热现场环境下智能电能表可靠性验证方法
Reliability verification of smart electricity meters under high temperature and low humidity environment
摘要
Abstract
The general technical specification for smart electricity meters requires that the reliable life of the electricity meters should be no less than 16 years.How to verify the reliability of smart electricity meters is not only a practical prob-lem to be solved urgently in the industry but also a difficult problem faced by academic.The sampling characteristic func-tion on average life expectancy,reliable life and failure rate are given under a Weibull distribution for reliability valida-tion,with the effects of acceleration of high temperature and low humidity environment,an accelerator is used to construct accelerated sampling characteristic functions for electricity meters,and then,the decision-making methods using two-sam-pling-parameters is discussed combining the engineering background of smart electricity meters.The reliability verification scheme of smart electricity meters in high temperature and low humidity environment is given in the section of experimental verification and analysis.Under the conditions of different use risk and acceptable failure times,the combination of test sample size and test time are calculated,and the table and figures were given,which are convenient for engineering appli-cation.It has a demonstration effect on reliability verification of measuring equipment in power industry under high tem-perature and low humidity environment.关键词
