摘　　要：介绍25 Hz交流二元继电器的基本特征,讨论其理想相位角随轨道线圈电压值动态变化的原理。针对理想相位角的测试难点,研究实验室适用的反推逼近测量方法,找到轨道线圈电压与相位角的关系,逐步调试出相位角临界点,进而计算出理想相位角。解决了因轨道线圈电压值设置不同而影响理想相位角测试结果的问题。The article introduces the essential features of 25 Hz two-element relays,discussing the principle that its ideal phase angle changes dynamically with the voltage value of rail coils. With a view to the difficulty in testing the ideal phase angle,it studies the inverse approximation method proper for laboratories. It clearly states that it shall find the relationship between the voltage of rail coil and the phase angle,gradually work out the critical point for phase angle and then calculate the ideal phase angle. The article solves the problem that various voltage settings of rail coil can affect the test result of ideal phase angle.
