压水堆核电站闭路电视系统改进优化

Improvement and Optimization of PWR Nuclear Power Plant Closed Circuit Television

摘要: 介绍了国内某核电站闭路电视系统出现的设备老化，故障率上升等典型问题。通过对闭路电视系统(DTL)系统架构以及原解码器设备选型的分析与研究，提出了闭路电视解码器替代改进方案，此设计改进方案已实验验证被成功应用于国内某核电机组，设备运行可靠稳定，对国内其它核电站闭路电视系统的改进具有借鉴意义。

Abstract: This paper introduces some typical problems in the Closed Circuit Television of a nuclear power plant in China, such as equipment aging and rising failure rate. Through the analysis and research of Closed Circuit Television (DTL) system architecture and the selection of original decoder equipment, this paper puts forward a closed-circuit television decoder replacement improvement scheme. This design improvement scheme has been successfully applied to a domestic nuclear power unit in Validation, Closed Circuit Television, and the equipment runs reliably and stably, which has reference significance for the improvement of Closed Circuit Television Closed Circuit Television in other domestic nuclear power plants.
