中文摘要: 根据方位伺服系统工作原理、故障现象和故障原因,对遵义新一代多普勒天气雷达运行7年多来10次发生的方位伺服系统故障维修工作进行归纳总结。认为:(1)遵义雷达出现的方位伺服系统故障可以归纳为5类典型故障,并对应找出具体维修措施;(2)方位伺服系统组成部件较多,而且分布在多个不同地方,检修工作难度大,维修人员需要掌握系统的组成和工作原理,然后进行分级判断和故障定位;(3)方位伺服系统维修常用检查仪器主要是示波器和三相万用表,因此要求技术保障人员熟练使用;(4)从发生故障部位来看,主要集中在方位驱动分机内,因此需要重点掌握方位驱动分机工作原理和分机内各部件工作原理,对应的检测参数和测量值,特别要记住一些检测波形。总之,随着雷达使用年限的增加,雷达设备故障率在增加,而故障维修工作纷繁复杂,如何保证较高的雷达可利用率,这就要求台站人员在了解技术说明书、原理图的基础上,在每次故障维修过程中及时总结各种故障维修措施,积累维修经验。
Abstract:According to the position servo system working principle, fault phenomena and fault causes, the servo system maintenance work for a new generation of Zunyi Doppler weather radar is summarized as follows: (1) The orientation of the servo system in fault can be classified to five kinds of typical faults, and specific measures corresponding to maintenance are found out; (2) Position servo system has many components, distributed in many different places,thus repair work is difficult, the maintenance personnel have to master system composition and working principle, and then through graded judgment found out the fault location;(3) Oscilloscope and three-phase multimeter are mainly used in position servo system maintenance and inspection, thus technical personnel must be skilful in using; (4) From the occurrence of failure positions to see, faults are mainly concentrated in the position driving system, thus technical personnel have to master the azimuth drive principle, the inspection parameters of corresponding parts and the measured values, especially to remember some test waveforms.
