田湾核电站绝对位移探测器新型安装方式的研究

摘要

本文对田湾核电站振动噪声诊断系统使用的堆芯振动测量探测器——绝对位移探测器及其安装方式进行了介绍，并分析原安装方式的缺陷，针对原安装方式进行改进，研究出一种新型的安装方式。本文着重对此安装方式进行介绍，并分析其优点，新型安装方式的成功应用可为新建核电站类似探测器的安装方式提供参考和经验。%This paper introduces the absolute displacements meter of vibration noise diagnostic system(VNDS) and its installation which monitor the vibration of the core equipment in Tianwan Nuclear Power Station(TNPS) , analyses the shortcoming of the original installation, improves the original installation, and develops a new method of installation. This paper introduces the installation method, and analyses its advantage. The using of new method of installation can provide reference and experience for installation of detector similar to absolute displacements meter in new-building nuclear power stations.
