摘要
随着国内大中型水电站的投运及电站监控方式的明确，电站的火灾自动报警系统处于越来越重要的位置。光纤分布式温度监测装置逐步在大型电站中得到应用，笔者根据多个电站的火灾自动报警系统设计工作，总结了光纤分布式温度监测装置的应用原理，供同行参考。
With the operation of large and medium-sized hydropower station and definition of monitoring mode for power station in China, fire auto alarm system plays a more and more important role in the power station. The optical fiber distributed temperature monitoring equipment has been gradually applied in the large-sized power station. The writer summarizes the application principle of the optical fiber distributed temperature monitoring equipment, based on design work for fire auto alarm systems for many power stations, only for reference.
