分布式光纤测温系统在任家庄选煤厂预防电力电缆火灾中的应用

摘要

针对目前选煤厂安全中突出的火灾探测问题，提出了一种比较成熟的分布式光纤测温系统。该系统采用光时域反射技术和拉曼散射测温技术，由测温光缆、分布式光纤温度分析仪和监测计算机构成，具有极高的灵敏度和定位精度。它的应用对实现选煤厂的安全生产起了很大的作用，对预防事故的发生具有重要的工程实用价值。%Aiming at the coal preparation plant safety issues highlighted in fire detection, we propose a more mature distributed optical fiber temperature measurement system. The system uses optical time domain reflectometry techniques and Raman scattering temperature measurement, temperature measurement by fiber optic cable, fiber optic distributed temperature analyzer and monitor computer, having a high sensitivity and precision. Its application to the achievement of Coal production safety played an important role in the prevention of accidents has important practical value.
