摘要
介绍了分布式光纤测温原理,重点分析了分布式光纤测温系统在煤矿带式输送机、输电电缆、电气设备和采空区火灾防治中的应用及具体的实施。工业性试验表明,该分布式光纤测温系统能准确、快速地对温度进行监测和预警,测温误差为±1℃,定位精度为1m,响应时间为20s。
The principle of distributed fiber temperature measurement was introduced,application and implementation of distributed fiber temperature measurement system in coal belt conveyor,power transmission cables,electrical equipments and fire prevention for goaf were mainly analyzed.The industrial test showed that the system can monitor temperature accurately and warn opportunely,and the measurement error is ±1 ℃,the positioning accuracy is 1 m,the response time is 20 s.
