摘要
AP1000核电厂首次将分布式感温光纤探测系统应用于1E级与非1E级电缆桥架火灾探测。文章介绍了分布式感温光纤探测系统技术原理,分析了感温光纤探测系统的结构及其特点,并根据核电厂的特殊环境,研究了对感温光纤的影响以及提出了相关建议,最后介绍了AP1000分布式感温光纤探测系统设计、光纤布置方案。
AP1000 nuclear power plant firstly applied the distributed temperature sensing optic fiber monitoring svstem for monitoring Class 1E and Non-Class 1E cable trays. This paper introduces the technical principle of distributed temperature sensing optic fiber monitoring system, and analyzes the system configuration and characteristics. According to the special environmental condition of the nuclear power plant, the influence on temperature sensing optic fiber is studied and relevant proposals are put forward. The system dean and fiber layout proposal are also introduced according to the AP1000 design.
