摘要

光纤电流传感器以其诸多的优点一直备受高压输电领域的关注。随着电力工业的发展

大容量、远距离的特高压输电已经成为我国电网发展的必然趋势

M-Z干涉仪作为一个典型的代表

自然也不例外。分析了磁致伸缩材料的各项参数

得出了磁致伸缩材料的磁致伸缩量与磁场的关系式

通过理论计算了波长漂移量与电流的关系式

并利用光谱仪对其进行波长解调

结果表明:实验与理论相一致。

Abstract

Fiber-optic current sensor takes advantages in the field of high voltage power transmission.With the development of electric power industry

super-high voltage transmission of large-capacity and long-distance becomes the inevitable trend.As a typical representative

M-Z interferometer is not exceptional.The parameters of magnetostrictive material are analyzed

and the relation between flexible quantity of magnetostrictive material and magnetic field is obtained.The relationship of the wavelength shift and the current is calculated by theoretical analysis

and its wavelength is demodulated by using of the spectrometer.The results show that the experiment is consistent with the theory.
