摘要: 以控制棒驱动机构为研究对象,基于机构结构噪声检测原理,自主研发了一套故障检测仪,并在试验台架模拟控制棒驱动机构上进行了测试分析,测试结果表明该检测仪可实现控制棒驱动机构的故障鉴别,为核反应堆控制棒驱动机构的安装调试和检修提供了一种科学有效的故障检测手段。Abstract: Taking the CRDM as the study object, a fault detection instrument based on the detection theory of the mechanism structure noise is developed and tested on an experimental CRDM. Test result shows that the fault detection instrument can distinguish the fault of CRDM. An scientific effective fault detection method is provided for the installation and overhaul of CRDM.
