摘　　要：控制棒驱动机构作为反应堆控制和核安全保护系统的执行机构,对其运行状态进行有效监测是防止反应堆发生控制棒卡棒、滑棒和驱动失灵的重要措施。本文在分析控制棒驱动机构动作原理的基础上,通过对驱动机构探测方法、信号分析处理方法以及故障鉴别方法的研究,实现了对控制棒驱动机构的电流监测与故障诊断,为驱动机构电流监测与故障诊断系统的应用奠定了技术基础。The control rod drive mechanism(CRDM) is the actuator of the reactor control and nuclear safety protection system. An important measure to prevent the occurrence of control rod stuck, sliding rod and driving failure in the reactor is to effectively monitor the operation status of the CRDM. Based on the analysis of the action principle of the control rod driving mechanism, this paper realizes the current monitoring and fault diagnosis of the control rod driving mechanism by studying the detection method, signal analysis and processing method and fault identification method of the driving mechanism, which lays a technical foundation for the application of the current monitoring and fault diagnosis system of the driving mechanism.
