摘要
设计了一种便于携带的核电堆外探测器故障诊断装置。该装置主要由脉冲放大模块、电流采集模块、正负高压模块与数字处理模块组成。该装置可对涂硼正比计数管的脉冲信号进行放大调理,然后通过高速ADC采集与上位机实现对脉冲信号的波形分析;还可对补偿电离室与非补偿电离室的电流信号进行I/V转换与数字化处理,然后通过上位机实现对电流数据的分析。通过测试验证了装置在脉冲波形分析和电流数据分析的最终效果,满足核电厂工程检修应用的要求。
A fault diagnosis device for nuclear power plant ex-core detector is designed.The device is mainly composed of pulse amplifier module,current acquisition module,positive and negative high voltage module and digital processing module.The device can magnify and adjust the pulse signal of boron-lined proportional counter tube,and then realize waveform analysis of the pulse signal through high-speed ADC acquisition and upper computer.In addition,I/V conversion and digital processing can be carried out on the current signal of compensated ionization chamber and non-compensated ionization chamber,and then the current data can be analyzed by the upper computer.The results of pulse waveform analysis and current data analysis are verified by testing,which meets the requirements of nuclear power plant engineering maintenance and application.
