摘要

现阶段实用化的有源电子式电流互感器主要由3部分构成:基于空芯线圈的高压传感部分、处于低压侧的信号调理部分、高低压侧之间的能量和信号传输部分。本文就相关的关键技术进行了研究:高准确度空芯线圈的制备方法、系统暂态性能研究、高压侧供能方法、可靠性分析

为有源电子式电流互感器的实用化作了有益的探索。

Abstract

There are three parts in practical active electronic current transformers of nowadays: sensing unit based on Rogowski Coil at high voltage level

signal processing unit at ground level

and laser power and signal transmission system.This paper is focused on the research of manufacture of Rogowski Coil with high accuracy

transient performances and system reliability

which brings helpful suggestions for the practical application of active electronic current transformers.
