摘要
针对综合管廊感温光纤的能否采用"S"形敷设存在疑惑,结合现行GB16280-2014《线型感温火灾探测器》标准要求进行分析,以及GB50116-2013中对线型光纤感温火灾探测器最小报警长度技术指标要求,从火灾探测器设计角度剖析线型光纤感温火灾探测器可以具有比感温电缆更具技术优势;提出了一种高空间采样间隔、高空间分辨率的线型光纤感温火灾探测器设计方案;测试表明探测器可实现取样间隔0.2m,温度精度可达±1℃,技术指标可替代缆式线型感温火灾探测器要求。该探测器在神东大柳塔矿区综合管廊动力电缆火灾监测系统中应用,取得了良好实测效果。
According to the comprehensive pipe gallery temperature sensing fiber can take the form of"S"laying doubts,the current GB16280-2014 linear temperature sensing fire detector is analyzed in combination with the standard requirements,and GB50116-2013 of the linear optical fiber temperature detector alarm minimum length requirement of technical indicators.Analysis of line type optical fiber temperature detector can have more advantage than technical the temperature sensing cable from the angle of fire detector design.This paper puts forward a linear optical fiber temperature detector design scheme of a high spatial sampling interval,high spatial resolution.Test show that the detector can realize the sampling interval 0.2m,the temperature accuracy of 1 deg C,technical indicators can replace the cable linear temperature sensing fire detector requirements.The detector applies in Shendong Daliuta comprehensive power plant pipe power cable fire monitoring system,and achieves good results.
