摘　　要：介绍了万能式断路器欠电压重合闸功能的应用需求,采用断路器本身标配的智能脱扣器来实现电压采样、判断及动作输出,将输出信号直接控制分励脱扣器与合闸电磁铁的方式来实现断路器的分/合闸动作,并配备延时动作等功能设置。实际测试表明,方案投资低、易于实现、动作精准,能满足实际工程应用的要求。This paper introduced the function and the application requirements of the air circuit breaker＇s under-voltage reclosure. The voltage sampling,verdict and action outputs were realized by using an intelligent trip unit of the air circuit breaker. The output signals will directly control the shunt release and the closing electromagnet to realize the breaking and closing motions of the air circuit breaker,and it also has function sets such as delay action and so on. The test results show that the project is enough to meet application requirements because of its low investment cost,easy to achieve,and accurate motions.
