摘要:
设计并搭建了一种基于相位敏感光学时域反射技术(Φ-OTDR)和布里渊光时域反射技术(BOTDR)复合的分布式地埋电缆光纤传感系统。该系统通过测量光纤中激光脉冲后向散射光的变化，可对地埋电缆的温度、振动和应变等信息进行分布式监测。根据振动和温度的变化特性，可实现对外破、短路、塌陷等突发事件的提前预警及精确定位。该系统具有结构简单、测量精确、稳定性好等优点，为电力系统的安全运行提供有力保障。
Abstract:
In this paper, a distributed optical fiber detection system based on phase sensitive optical time domain reflectometry(Φ-OTDR) and Brillouin optical time domain reflectometry(BOTDR) is designed and built for buried cable.The system can monitor the temperature, vibration and strain of the buried cable by measuring the change of the backscattered light of the laser pulse in the fiber.According to the changing characteristics of vibration and temperature,it can realize early warning and precise positioning of unexpected events such as external breaking, short circuit and collapse.The system has the advantages of simple structure,accurate measurement and good stability,and provides a powerful guarantee for the safe operation of the power system.
