摘　　要：根据中国气象局探测中心对全国雷达2006—2015年的备件消耗评估和对全国CINRAD/SA雷达2007—2015年的故障归属进行统计发现,发射机故障率仅次于伺服系统,这与发射机长期处于高压强电的工作环境密切相关。发射机故障中,高压问题直接导致停机,严重影响观测,是比较难处理的一类故障。通过统计全国CINRAD/SA雷达发射机的高压故障归属与检修经验,结合相关组件的参数特征,梳理常见高压故障,归纳总结出CINRAD/SA雷达高压故障的排查方法,并从项目组收集的案例库中选取2个典型个例进行分析,为台站提供借鉴。From the consumption assessment for detecting radar spare parts of the CMA Meteorological Observation Center from 2006 to 2015 and the fault cases acquired from nationwide CINRAD/SA radar stations from 2007 to 2015 by the project team,it is found that the transmitter failure rate is second only to the servo system,which is closely related to the high-voltage work environment for a long time,seriously affecting the observation,being very difficult to deal with.This paper summarizes the methods to solve the high-voltage faults by gathering the maintenance experiences from the nationwide CINRAD/SA radar stations,binding the parameter characteristics of the related components and analyzing common highvoltage faults.Two typical high-voltage fault cases are studied to provide reference for stations.
