摘要
依据光纤Bragg光栅测温原理,研究了电力电缆温度在线监测方法。通过ANSYS有限元仿真,得出电缆内部温度云图,建立电缆缆芯温度与表皮温度的温升方程,并与IEC-60287标准进行比对,证明仿真所得温升方程具有更高的准确性。根据实验原理图,选择合适器件,搭建实验系统。
Based on the principle of temperature measurement of fiber Bragg grating, the online monitoring method for power cable temperature is studied. Through ANSYS finite element simulation, the inner temperature cloud diagram of the cable is obtained and the temperature rise equation of cable core temperature and skin temperature is established. Compared with IEC-60287 standard, it is proved that the temperature rise equation is more accurate, according to the experimental schematic diagram, to select the appropriate device and build the experimental system.
