摘要
针对传统布里渊光时域反射传感系统空间分辨率低的问题,详细分析了基于双脉冲布里渊光时域反射(DP-BOTDR)的传感系统原理,并对DP-BOTDR系统的性能进行了仿真,结果表明DP-BOTDR技术具有高测量精度、高空间分辨率的优点。根据500kV电力变压器绝缘性能在线监测需要和绕组结构,探讨了DP-BOTDR系统在500kV变压器绝缘监测中的应用方案,设计了基于DP-BOTDR光纤传感技术的变压器在线监测系统。
To solve the problem of the low spatial resolution of traditional Brillouin Optical Time Domain Re- flectometry （BOTDR）, the principle of Double Pulse （DP） BOTDR sensing system is analyzed in detail. The performance simulation of DP-BOTDR system indicates that this technology has the advantages of high mea- surement accuracy and spatial resolution. According to acquirement of online insulation monitoring and the winding structure of 500kV power transformer, the application scheme of DP-BOTDR system in insulation monitoring of the transformer are discussed, and the online monitoring system based on the DP-BOTDR sys- tem is designed.
