摘要

开关柜在供电系统中起着传输和分配电能的作用，电流作为开关柜监测的一个重要物理量对其进行准确测量具有重要意义。针对穿心式电流互感器测量电流时易受相间磁场干扰，体积大，无法数字化输出问题，提出了一种基于磁通门传感器的母排电流测量方法，通过在母排上增加分流槽以及对后端电路进行设计使其具备较强的抗干扰能力。首先对其测量方法和抗干扰原理进行理论分析，然后在Comsol中建立母排模型对测量方法进行仿真验证，同时对磁场与电流之间的传递关系进行有限元标定。最后搭建母排电流测量实验平台，实验结果表明传感器样机误差小于0.8%，在15 mm处存在干扰磁场时误差仅为2.35%，证明了该测量方法的准确性和有效性。

Abstract

Switchgear cabinet plays a vital role in transmitting and distributing energy in power supply system. As curent is an critical physical parameter in switch gear cabinet monitoring

its accurate measurement is of great significance. In view of such issues of the spiercing current transformer as susceptibility to interphase magentic field interference

large volume and lack of digital output capability

in this paper a busbar current measurement based on fluxgate sensors is proposed

which has strong anti-interference ability by adding shunt slot on the busbar and designing the back-end circuit. First

the measurement method and anti-interference principle are analyzed theoretically. Then

the busbar model is established in Comsol to simulate and verify the measurement method and

at the same time

the transfer relationship between magnetic field and current is calibrated by finite element method. Finally

an experimental platform for busbar current measurement is set up.The experimental results show that the error of the sensor prototype is less than 0.8%

and the error is only 2.35% in case of interference magnetic field at 15 mm

which proves both accuracy and effectiveness of the measurement method.
