摘要
电缆沿线的温度实时监测是保障其安全运行的重要手段。在理论分析光纤后向拉曼散射和光时域反射原理的基础上,设计了分布式光纤测温系统和方案和软件构架,并将设计的系统应用于动力电缆的在线监测,取得了良好的测试结果,为动力电缆的故障预警提供了可靠的科学手段。
Real-time monitoring of temperature along the cable is very important for ensuring the safe oper-ation. Based on the theoretical analysis of Raman back scattering of optical fiber and optical time domain reflection principle, optical fiber distributed temperature measurement system, scheme and software architecture are designed. The system is applied to the online monitoring of power cable, and good results are achieved. It provides a reliable scientific tool for the fault early warning of power cable.
