Abstract

For the application of high-frequency current detection in power systems, such as very fast transient current, lightning current, partial discharge pulse current, etc., current sensors with a quick response are indispensable. Here, we propose a high-frequency magnetoelectric current sensor, which consists of a PZT piezoelectric ceramic and Metglas amorphous alloy. The proposed sensor is designed to work under thickness-shear mode, with the resonant frequency around 1.029 MHz. Furthermore, the proposed sensor is fabricated as a high-frequency magnetoelectric current sensor. A comparative experiment is carried out between the tunnel magnetoresistance sensor and the magnetoelectric sensor, in the aspect of high-frequency current detection up to 3 MHz. Our experimental results demonstrate that the thickness-shear mode magnetoelectric sensor has great potential for high-frequency current detection in smart grids.

摘要

对于高频电流检测在电力系统中的应用，如极快速瞬态电流、雷电流、局部放电脉冲电流等，具有快速响应的电流传感器是不可或缺的。在此，我们提出一种高频磁电电流传感器，它由PZT压电陶瓷和美特格拉斯非晶合金组成。所提出的传感器设计为在厚度剪切模式下工作，谐振频率约为1.029MHz。此外，所提出的传感器被制作为高频磁电电流传感器。在高达3MHz的高频电流检测方面，对隧道磁电阻传感器和磁电传感器进行了对比实验。我们的实验结果表明，厚度剪切模式磁电传感器在智能电网的高频电流检测中具有巨大潜力。
