Abstract:

It is of great significance to study the reliability and life prediction of relays.The mechanism of relay storage failure is summarized,and the research status of relay storage reliability is analyzed.The definition of relay degradation is explained,and the advantages of life prediction based on the degradation law are introduced.The application and characteristics of reliability evaluation by the random degradation model are summarized,such as Wiener model,Gamma model and Weibull model.Finally,the application of accelerated storage test method in the field of relay reliability prediction is briefly summarized,and the shortcomings of relay storage reliability analysis and the future research direction are summarized.

Key words: relay, life prediction, reliability, storage, degradation test
