Research on Reliability Test Technology of Overload Relay

The reliability test of the overload relay is an important way to find out weak parts and improve the reliability of products. So reliability test technology is of great significance. The reliability test method of overload relay is studied on. By use of reliability tester, the reliability test for the typical productsJRS1D-25 is carried out. According to the test result, the reliability analysis is developed from two aspects of product structure and material characteristics. The failure reasons of the overload relay are found out and the improvement measures are put forward.
