摘要
介绍了光纤布里渊光时域分析仪(BOTDA)的测量原理,设计了一种适合同时获取光纤分布式温度和应力应变的OPPC结构,提出了采用BOTDA在线监测该结构运行状态的技术方案。通过将该方案应用于110kV输电线路中,验证了方案性能,并分析了测量结果。
The paper introduces the measurement principle of the Brillouin optical time domain analyzer （BOTDA）, designs a new OPPC structure which is suitable for the simultaneous measurement of the temperature and stress/strain of the optical fiber, and proposes a technical scheme based on BOTDA for on line monitor- ing. The paper applies the scheme to the 110kV power transmission line, verifies the performance of the scheme and analyzes the measurement results.
