摘　　要：根据舟山站CINRADSB型发射机在试运行初期一起复杂故障的现象,结合电子设备的维修经验,分析了该故障发生的根本原因及由它激发的几个故障部位电路原理,详细地介绍了这例复杂障的芯片/元件级排障过程。最后就试运行期间各台站CINRADSB型发射机高压打火频繁发生的现象提出一些建议,希望能防止同类故障再次发生。Based on some phenomena of a complex failure in ZhouShan CINRAD-SB transmitter during the first running period, combining with repairing experiences of electronic equipments, the failure source and some electronic circuits of other failure units induced by the former failure are analyzed, especially, some correlative principle failure diagrams are drawn, the process of repairing these failures was in detail introduced on IC chip/electron-element. In fact, these principle failure diagrams and repairing experiences are useful to diagnose failures of CINRAD-SB transmitter on IC chip/electron-element. In the end, as it was the fact that transmitter high voltage shorting-circuit frequently happened during the first period, some suggestions to protect from the similar failures taking place are put forward.
