一种电子开关温升试验实时监测与自动控制系统

Design of a system for temperature rise test on electronic switch

本文针对电子开关温升试验步骤多、周期长、对试验人员要求高等特点,设计了一种实时监测与自动控制系统。用户通过软件界面设置试验程序,由试验程序对可编程变频电源的电源参数进行设置,并通过可编程逻辑控制器控制一组交流接触器,实现试验电源参数的自动设置和相应试验负载的自动连接。通过温度数据采集器实时采集温度数据,由试验程序判定温度达到稳定条件后衔接下一试验步骤直至结束,实现整个试验过程的全自动化。该系统既缩短试验周期,减少试验能耗,同时也能提高不同人员试验的结果一致性。

Temperature rise test on electronic switch has many steps and long duration. In this paper, a real-time monitoring and automatic control system for temperature rise test on electronic switch was designed. Test procedure which control test power supply and test load can be set up by user through the software interface. Temperature data can be real-time collected by a temperature data collector. Test period will be shorten. Energy consumption during the test will be reduced. Test results from different testers will be more consistent.
