摘要

利用通电螺线管与永磁铁之间的作用力

提出了一种测量电流的方法。光纤Bragg光栅（FBG）在永磁铁的牵引下发生轴向应变

引起Bragg中心波长的漂移

通过解调中心波长漂移量对电流进行测量。实验中采取多匝数螺线管和小电流来模拟大电流

对0

A的直流电流进行了测量。实验结果表明:中心波长漂移量与电流有很好的线性关系

线性度为0.9998

电流灵敏度约为0.97 nm/A。

Abstract

Based on the principle of electromagnetic force

a method for current measurement is proposed.The axial strain emerges and leads to central wavelength drifted if Bragg under the pull of permanent magnet.The current is measured by demodulating the wavelength shifts.Experiments are carried out by using many circles of solenoid and small current.The DC of 0

A is test.The experiment results show that the relation between the wavelength shift and the current has a linearity of 0.9998

and the sensitivity is about 0.97nm/A.
