| 摘 要： | 为研究长期运行光纤复合架空地线(OPGW)的应变性能,使用高精度的分布式光纤传感监测设备布里渊光时域分析仪(BOTDA)对新缆和不同覆冰环境下的旧缆进行应变监测,对比分析了OPGW光缆内光纤的布里渊频率在长期外界环境作用下的变化。试验结果表明,运行时间和覆冰等级是影响OPGW光缆内光纤应变性能的主要因素。

| Abstract: | In order to study the strain performance of optical fiber composite overhead ground wire(OPGW)in long-term operation,Brillouin optical time domain analysis(BOTDA)is used to monitor the strain of new cables and old cables in different icing environments,and the Brillouin frequency of fiber in OPGW cables in long-term external environment is compared and analyzed.The test results show that the operation time and icing level are the main factors affecting the strain performance of fiber in OPGW cables. |
