CINRAD/CC雷达发射机磁场电源故障诊断与调试

Diagnostic and Adjustment Technique of CINRAD/CC Radar Transmitter Magnetic Field Power Source

统计近5年云南5部CINRAD/CC雷达的73次故障,发现发射系统磁场电源故障达21次,相对而言磁场电源故障率较高。通过归纳21次磁场电源故障的排除过程,总结出检测和分析磁场电源故障的技术方法,并给出了关键测试点的波形、调试指标,供技术保障人员参考。通过文山个例并结合多次实际经验认为,更换元器件常可能带来一些雷达性能参数的变化,易形成其他故障的隐患,故排除故障后统调相关系统是十分必要的。

The statistical 73 breakdowns for 5 CINRAD/CC radars at Yunnan in the recent 5 years have discovered that the failure from launching system magnetic field power reaches 21 times,relatively speaking, the failure rate of magnetic field power source is high.Through analyzing and inducing the elimination processes of 21 magnetic field power failures,we summarize,examines and analyzes the computing technique for the magnetic field power failure,have given the essential test point profile,the debugging target, as well as causes for radar parameters and emission power,klystron change situations and the debug method, which can be references for the technical support personnel.Meanwhile,take a Wenshan CINRAD/CC typical fault analysis and the eliminaton as an example,has presented the above method and the target specifically, and use the practical experience obtained through the elimination process of failure many times, then replace the primary device often possibly to bring some radar performance parameters to change,easy to cause other breakdowns,therefore after proposing the trouble shooting,the padding-system related is very important.
