Abstract:

The relay’s storage reliability evaluation and storage life prediction are important contents to study the reliability of the relay.The cause of relay storage failure is analyzed from the aspects of process factors,environmental factors,failure mechanisms and failure modes,etc.The reliability evaluation methods based on Bayesian method,Weibull distribution method and performance degradation model are introduced,and the advantages and disadvantages of several different storage reliability evaluation methods and their applicable scope are analyzed.The relay storage life prediction method based on accelerated storage test is summarized.It is concluded that referring to various fault factors can improve the accuracy of the test.The shortcomings of storage life prediction and future research directions are summarized.

Key words: relay, reliability assessment, storage life, accelerated storage test
