摘　　要：根据雷达发射系统工作原理、故障现象和故障原因,对甘肃省新一代多普勒天气雷达运行多年来发生的20余次发射系统故障维修工作进行归纳总结。甘肃省新一代多普勒天气雷达发射系统故障可归纳为6类典型故障,对应找出具体维修措施,并给出了关键测试点的波形、调试指标,供技术人员参考;发射系统组成部件复杂,高压器件较多,维修难度大,维修人员需掌握系统组成和工作原理,然后进行故障分级判断和故障定位;发射系统维修常用检查仪器主要是示波器和三用表,因此要求技术保障人员熟练使用。随着雷达使用年限的增加,雷达设备故障率也在增加,而故障维修工作纷繁复杂,这就需要把雷达故障进行总结、分类,同一种类型的故障对应相应故障处理方法,这样就能大大提高雷达维修的时效性。Due to launch system of radar contains lots of complex components and high - pressure devices, the maintenances are diffi- cult, which require technicians knowing the structure and working principle of the system very well for the fault type judgment and fault location. Moreover, the frequencies of radar faults are rising gradually with the service life, it is thus necessary to summarize and clas- sify the faults of radar to make the complicated repair in radar maintenance more efficient, because different fauhs need corresponding methods to solve. Accordingly, this paper summarized the maintenance of the transmitter of China new generation radar （CINRAD/ CC） applied in Gansu Province based on the operating principle, the occurring fault and the fault cause of the transmitter system. It was found that the faults of the transmitter system of CINRAD / CC were classified into six typical types. Through finding out the cause of each type of fault, the corresponding maintenance method was defined, and the waveform and debugging indicators of the critical test point were obtained too. Furthermore, technicians need to use the oscilloscope and muhimeter skillfully. It is believed that these re- suits can be not only a tutorial material for the beginners of radar maintenance, but also a useful reference for the technicians of radar maintenance.
