| 摘 要： | 利用光纤光栅(Fiber Bragg grating,简称FBG)、超磁致伸缩材料(Giant magnetostriction material,简称GMM)和基于双芯光纤滤波器的解调系统实现了交流电流的测量。在介绍超磁致伸缩材料的磁致伸缩效应、光纤光栅检测电流原理以及双芯光纤滤波器解调原理的基础上,借助超磁致伸缩材料和光纤光栅等构建了电流测量单元。利用设计的电流测量单元,在施加0～4.5A(50Hz)范围的交流激励电流时,经基于双芯光纤滤波器的解调系统解调,验证了采用该方案检测电流的可行性。

| Abstract: | The measurement of alternating current (AC) is realized by using fiber Bragg grating (FBG), giant magnetostriction material (GMM), and the interrogation technology of twin-core fiber filter. Based on the theoretical analysis of the principle of the FBG current measurement, the magnetostrictive effect of GMM, and the interrogation technology of twin-core fiber filter are introduced. The sensing unit of AC current measurement is constructed with GMM and FBG. When the AC exciting current is in the scope of 0~4.5A (50Hz) through a solenoid coil, the feasibility of AC current measurement by using this method was verified. |
