Storage Failure Mechanism Analysis and Reliability Improvement Measures for Electromagnetic Relay

Abstract

In order to solve the problem of unknown cause of parameter degradation and incomplete failure mechanism, and to obtain the data support required for the storage life evaluation of the whole machine system, a certain type of electromagnetic relay was selected for accelerated storage degradation test. The failure mode, the law and mechanism of electrical parameter change under storage condition were studied. On this basis, the improvement measures of relay reliability are put forward, which is of certain significance to improve the reliability of electromagnetic relay and system.
