摘　　要：文章对3种光纤传感技术(B-OTDR/B-OTDA,DTS,FBG)用于架空输电线路状态监测进行了比较。DTS由于检测方法所限只能检测温度。虽然B-OTDA可以同时检测温度和应力,但由于光纤寿命、OPPC/OPGW制造技术以及价格昂贵等因素影响,不适合用于架空输电线路应力监测。光纤光栅传感技术具有价格适宜、精度高、速度快、测试距离长、可制成各种传感器等优点,适合用于架空输电线路的温度及应力等状态监测。This paper compares three optical fiber sensor techniques （B-OTDR/B-OTDA, DTS and FBG） applied to the status monitoring of overhead transmission line. DTS can only test temperature due to the limitation of detection method. Although B-OTDA is able to examine temperature and stress simultaneously, it is not suitable for the status monitoring of overhead transmission line because of the restrictions of fiber life, OPPC/OPGW manufacture technique, high price, and etc. Fiber Bragg Grating （FBG） has advantages of price, precision, speediness, long testing distance, and can be applied to producing variety of sensors. Therefore, FBG is applicable to monitoring the temperature, stress and other conditions of OPGW transmission line.
