摘要
核电厂数字化仪控系统的国产化对于我国的核电发展具有重要意义,针对其中对于模拟量采集模块的技术要求,自行研制出了一款采集精度达到万分之二AI模块,对于输入阻抗、元器件温度漂移、隔离等影响采集精度和稳定度的主要因素进行了原理性分析,阐述了模块的设计思路。长期运行试验结果显示模块的精度、温漂、共模和差模抑制比均达到设计要求.目前该模块已应用于核电厂现场。
The domestication of digital instrumentation and control（ IC） system in nuclear power plant has important significance for the development of nuclear power in China. According to the technical requirement of analog data acquisition for the domestic digital IC in nuclear power plant,an analog input module with 0. 02%precision was developed. The principle analysis was given to the main factors affecting the precision and stability such as input rejection,temperature drift,isolation and etc.,and the design of the module was presented.The results of long- term running test demonstrate that the precision,temperature drift,common mode and differential mode rejection ratio of the module have reached the design requirements. The module has been currently used in the fields of nuclear power plants.
