电机负载的继电器电寿命试验条件的研究

本文研究交流单相异步电动机作为继电器负载时，继电器闭合与分断时电压与电流的试验条件。根据电弧数学模型、交流单相异步电动机运行等效模型，对继电器闭合、分断时触点间电压与回路电流的动态变化过程进行理论分析与计算机仿真研究，并与实际测量情况进行对比验证。最终得出继电器电寿命试验条件。

Research On Electric Longevity Testing Requirement of Relay Loading Motor

This paper researches the testing requirement of voltage and current when relay closed or opened if the relay loaded AC single phase separate step motor.On the basis Of current arc mathematical model,equivalent model of AC single phase separate-step motor working,this paper has thoery analysis and computer imitated research On the dynamic variation process of interpoint voltage and return circuit current when relay closed Or opened.It also finally gets the testing requirement of relay electric longevity by contrasting,testing and verify with actual survey condition.
