阐述了CINRAD/SA雷达磁场电源控制电路,对磁场电源控制板电路的场效应管驱动信号、控制板驱动信号、IGBT模块极间电压波形等关键测试点进行了调试,并给出了相应的标准波形示意图,对磁场电源输出电压、磁场电源电压保护和聚焦线圈电流保护进行了分步调试,根据在实际使用过程中出现的故障现象、故障判定处理,结合实物测试点给出了故障处理流程图,结合实际工作经验总结了磁场电源的相关故障排查点和故障排除方法,旨在为雷达磁场电源的现场故障处理提供帮助和参考。
The working state of the magnetic field power supply control circuits for CINRAD/SA Radar is described. Diagrams of the corresponding standard waveforms are given by means of debugging the driving signals of FET and the control panel, voltage waveforms between electrodes of IGBT modules, and some other test points of the circuits. After debugging the output voltage, the voltage protection of power supply, and the current protection of focus coil by steps, the flowchart of fault treatment is accomplished with the physical test points, real fault phenomena, and solutions. Based on the practical experiences, correlative troubleshooting points and solutions are summarized, aiming to offer some references for the spot fault treatment of radar magnetic field power supply.
