环境温度是影响电磁继电器触点侵蚀的一个重要因素。根据相同负载不同温度（常温＋20℃和高温＋125℃）下继电器10万次动作后的对比试验结果,对触点的侵蚀情况和测得的相关数据进行分析,解释两种环境温度下触点侵蚀不同及导致的测试结果差异。同时建立电磁继电器的静、动态特性模型,仿真分析触点侵蚀不同对相关参数的影响。最后推测两种温度下触点的不同失效模式并给出应采取的预防和改进措施。

Ambient temperature is an important factor influencing contact erosion of electromagnetic relay. In this paper,based on results of 1×10^5 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.
