摘要

超磁致伸缩材料（Tb0.30Dy0.70Fe1.95）在不同方向具有不同的磁致伸缩效应

在此基础上

提出了一种改进的基于超磁致伸缩材料的双光纤Bragg光栅（FBG）大电流传感器结构。通过检测2个Bragg光栅的波长漂移差得到被测电流。消除了超磁致伸缩材料的温度影响

解决了FBG的温度—应变交叉敏感问题

同时

增大了FBG的应变

提高了传感器精度。试验结果表明:在-10

0℃的温度变化范围内

该传感器2个Bragg波长差与电流变化具有较好的线性度

不受温度变化的影响。传感器的电流灵敏度为5.78×10-4nm/A

与理论值的相对误差为2.89%。理论与试验结果符合较好

表明该传感器结构是可行的。

Abstract

GMM has different magnetostrictive effect in different directions

based on this an improved double fiber Bragg grating（FBG） large current sensor configuration is presented.By monitoring the wavelength shift difference of two FBGs

the measured current can be obtained.The impact of temperature to GMM and the influence of temperature-strain cross sensitivity are eliminated.High strain and sensor sensitivity are obtained at the same time.The experimental results show that in the range of-10

0℃ the relation between the dispersion of two FBGs Bragg wavelength and current is linear

The current sensitivity of the sensor is 5.78×10-4nm/A

and the relative error is 2.89%.The theoretical and experimental results verify the

feasibility of the proposed sensor.
