摘　　要：介绍了一套交/直流接触器动作特性测试系统。系统实现了对交流接触器的选相分/合闸控制,采用激光位移传感器实现触头与铁心动态位移测试,驻极体传声器采集接触器闭合过程声音信号,霍尔传感器采集线圈回路和三相触头回路电压电流信号;同时使用数据采集卡将信号采集到上位机,完成数据的处理分析、自动测量、数据存储等功能。系统为交直流接触器的仿真研究、控制方案等提供技术支持,对提高接触器的设计与开发水平具有理论和实际意义。The operating characteristics test system of AC / DC contactor was introduced. It achieves phase selection in the closing and opening course of contactor. Keyence laser displacement sensor is used to achieve the test of displacement of contact and iron core changing over time. Moreover,the sound signal making in the closing course of contactor by electret microphone is captured. The voltage,current of coil and main circuit with three-phase contacts are obtained. All signals mentioned above transmitting to PC based on data-acquisition,the system achieves data processing,automatically measuring and saving. The test system provides technical support for contactor studying and simulation,control strategy verifying of AC / DC contactor. It is of theoretical and practical significance in the design and development of AC / DC contactor.
