热成像技术在动车组中的应用研究

在动车组调试阶段利用红外热成像技术对电气系统进行检测,能够快速、有效的发现接线端子松动、负载不平衡、过载等不易察觉的异常现象。对主要的电气部件及接线部位进行数据采集并结合测试点的发热状态拟建立基础数据库,为电气系统异常故障诊断提供一种快速、便捷的定位方式,进一步提升电气调试工艺水平。

Application of thermal imaging technologyfor EMU debugging

Using thermal imaging technology to detect the electrical system in EMU debugging process can quickly and efficiently find the loose terminals, unbalanced load, overload and other subtle anomalies. The based database established including the main data combining the voltage and current of the electrical components and heat state provides a fast and convenient way to locate abnormal electrical fault diagnosis system, at the same time, further enhance the level of electrical debugging process.
