摘　　要：介绍用于三相电动机缺相保护装置的设计方法,采用集成芯片TC783A为核心元件实现,有效地解决三相电动机其他保护元件的局限性。具有快速切断控制回路电源的功能及缺相指示和相序指示,试验证明系统工作性能良好。The paper introduces a design method for three - phase motor open - phase protection device, that is, using integrated chip TC783A as the core components to implement the design, to effectively resolve the limitations of the other protection parts of the three - phase motor. The protection device has the function of quickly switching off double - circuit supply, and of open - phase indication and phase sequence instructions. The test proves that the systemg performance is good.
