摘要
为了提高励磁线圈的工作运行的稳定性,设计了一种构造方形通孔结构的磁通门传感器,其由C型磁芯、激励源、激励线圈、检测线圈共四部分组成。在磁通门传感器中存在二个励磁线圈对磁芯通孔两侧形成对称缠绕,以相同的线圈匝数呈反向串联状态,按照与电力变压器铁芯叠片表面保持垂直的方式安装传感器磁芯接口用途磁通门传感器。以自激磁通门原理来产生激励电流设计激励电路,采用示波器开展实验测试得到:当变压器铁芯不存在直流偏置磁通的情况下测量线圈依然会测试出电压输出值,测试信号与偏置电流之间呈现非线性的单调变化规律。
In order to improve the working stability of the excitation coil,a fluxgate sensor with square through hole structure is designed,which is composed of c-type magnetic core,excitation source,excitation coil and detection coil.In the fluxgate sensor,there are two excitation coils that form symmetrical winding on both sides of the magnetic core through hole.The same number of turns of the coil is in reverse series,and the sensor core interface fluxgate sensor is installed in a way that is perpendicular to the laminated surface of the power transformer iron core.The excitation circuit is designed based on the principle of self-excitation flux gate to generate excitation current,and the experimental test is carried out by using oscilloscope to obtain.When the transformer core does not have dc bias flux,the measurement coil will still test the voltage output value,and the test signal and the bias current present nonlinear monotone change rule.
