摘要
对比分析了国内外感温光纤的铺设安装间隔参数。在此基础上设计并搭建了实验平台,进行了感温光纤顶部敷设方式探测地面油盘火灾的实验。通过调节顶棚高度,获得了不同顶棚高度下感温光纤报警响应的敷设间隔数据,认为分布式感温光纤的最佳安装间隔与美国的NFPA 72标准相符,感温光纤的安装间隔需要随天花板高度的增加而减小。研究可为工程施工提供参考和指导依据。
The laying space of fiber optic at home and abroad was analyzed comparatively. Designed and built an experimental platform for top laying temperature sensing fiber optic probing ground oil pan fire. The laying interval and alarm response time data under different ceiling height was obtained by adjusting the ceiling height. Results showed that the best laying interval suits with NFPA 72, and the space of fiber optic laying should reduce with the increasing of ceiling height. The study can provided information and guidance for building construction.
