核安全保护装置温漂性能改进的实验研究

核动力系统中,安全保护装置的温度漂移是一直存在的,它不仅影响整个控制系统的安全,而且影响该装置中各插件板的互换性。本文针对这一实际问题,在实验室用实际单元插件模拟现场温度变化的过程中,进行了参数测试。通过对电路及测试数据的分析,找出了问题所在,提出了改进措施。通过对改进前后测试数据的对比,证明改进之后性能有非常明显的提高。

Experimental Research on Temperature Drift Behavior Improvemet of Nuclear Safety and Protect Equipments

There alawys exists temperature drift in safty and protect equipments of nuclear power system. It affects not only the safety of the whole control system ,but also the exchangeability of various slots in the equipments. In order to solve this problem we use practical unit slots in lab to simulate the process of on-the-spot temperature variations and test their parameters. Through the analysis of the circuit and the testing data,we had found the cause of the problem,and had put forward corresponding improvement measures. By contrast of testing data with prior to improvement, we prove that the behavior is improved greatly after our improvement measures.
