Abstract：Ambient temperature is an important factor influencing contact erosion of electromagnetic relay. In this paper, based on results of 1×105 cycle operations with the same load under different temperatures (room temperature: +20℃, high temperature: +125℃), the erosion of contacts and the data of tests are analyzed, and the reasons of different contact erosions and different results of tests under the two ambient temperatures are given. Then, the static and dynamic model of electromagnetic relay is built; some parameters under the influence of different contact erosions are calculated and analyzed. Finally, the different failure modes of contacts are predicted under the two ambient temperatures, and some measures of prevention and improvement are given.
