近年来感温光纤测温系统在发电领域已得到了广泛的应用。介绍了光纤测温探测器的工作原理，论述了基于感温光纤技术的TFRC128-EFMS型火灾监控系统在某2×1 000 MW火力发电厂的应用实例。该电厂的消防火灾报警系统实体调试表明，TFRC128-EFMS型火灾监控系统各种性能良好，各项指标都能达到要求。感温光纤技术应在火电厂测控系统中推广应用。

In recent years, the fiber optic temperature measurement system has been widely used in the field of power generation. This Paper introduced the working principle of fiber optic temperature measurement detector, and presented an application example of TFRC128-EFMS fire monitoring system in a 2×1 000 MW power plant. The debugging results of fire alarm system show that all kinds of performance are good and each index can meet the requirements. So the fiber optic temperature measurement technique should be widely applied in power plants.
