摘要
云南昭通新一代天气雷达自2002年9月安装运行以来,伺服系统出现了方位(俯仰)R/D板故障、方位(俯仰)电源故障、汇流环和驱动器等方面的故障。通过这些故障实例,总结了如何根据故障现象结合雷达生产厂家提供的电路图图册,分析故障所在的伺服系统的工作原理、组成和流程,找到故障成因,排除故障的方法。在分析排查的过程中,总结出一些故障诊断的关键点及故障排除方法,如出现R/D变换板故障时检查XP2-7、XP2-8、XP2-9的输出波形,出现电源故障时根据驱动器上的数码管提示信息进行判断,出现汇流环故障时用万用表测试各连接点的链路畅通情况等。
According to the new generation weather radar system fault examples in Zhaotong since installation and operation in September 2002,in the servo systems there are azimuth（pitch） R/D board fault,azimuth（pitch） power fault,the slip-ring and drive fault,etc.Through these fault examples,describes how to analyze working principles,components and processes of servo system which locates the fault based on symptoms combine with circuit provided by the radar manufacturer,find the fault causes and clear faults.In the process of investigation,the key points of fault diagnosis and troubleshooting methods are summarized： such as R/D conversion board fault mainly checks the output waveform of XP2-7,XP2-8 and XP2-9;power fault is judged by the LED information;slip-ring fault mainly uses multimeter to test the connection point of the link flow conditions,etc.
