| 摘 要： | 针对现有的电缆温度监测方法主要存在无法检测电缆内部温度和测温时易受到应力影响等缺点。针对此本文研究采用低反射率光栅(wFBG)阵列智能复合电力电缆温度监测技术,用于实时监测电缆内部及外部的温度分布情况。通过免应力光栅阵列,解决了复合电缆和光缆的过程中因光纤受力而影响光栅波长准确测量从而造成对温度的影响问题。系统通过检测wFBG波长漂移得到温度信息从而实现高灵敏度高空间分辨率的智能电缆的分布式温度在线监测。搭建了基于wFBG阵列的复合电力电缆实验系统,结果表明,该系统可以实现对电缆内部及外部温度的高精度、高空间分辨率分布式测量,电缆沿线空间分辨率达到10 cm,测温精度达到0.1℃。该低反射率光栅阵列智能复合电力电缆温度监测系统可以满足智能电网运行的实际需要。
