摘要

针对实际电流互感器工作环境

不存在均匀的外界磁场

提出一种分析外界非均匀磁场对罗氏线圈的干扰的新方法。根据相邻电力线在线圈远近两侧产生的感应磁场方向

将其分成两部分

分别分析

并求出产生总的感应电动势恒为零。从而得出在罗氏线圈截面积和匝数密度均匀的条件下

非均匀磁场不会对罗氏线圈产生干扰。针对于干扰情况文中提出两种改进方法:提高匝数密度和线圈截面积的均匀度、增加屏蔽罩结构。最后通过两组实验

结果证明

提高匝数密度和线圈截面积的均匀度、屏蔽罩能有效减少非均匀磁场对罗氏线圈的影响

具有现实意义

可以满足精度要求。

Abstract

There is no uniform external magnetic field in the actual working environment of a current transformer.In this paper

a new method for analyzing the interference of non-uniform magnetic field on the Rogowski coil of current transformer is proposed.Magnetic field is created by adjacent power lines.According to the magnetic direction at both near and far sides of Rogowski coil

the coil structure is divided into two parts for respective analysis

and the total induced electromotive force is calculated to be zero

which indicates that the non-uniform magnetic field will not interfere with the Rogowski coil on the premise of uniform turns density and cross-sectional area of the coil.Two experiments are conducted

and the results show that the interference of non-uniform magnetic field on the Rogoski coil can be clearly suppressed by increasing the uniformity of the coil’s turns density and cross-sectional area

and adding a shield.
