摘　　要：针对ns级脉冲电流信号的测量,设计了一种带磁芯的新型自积分式罗氏线圈,具有信噪比高、动态范围广等优点。屏蔽盒开气隙防止涡流。屏蔽盒外层采用聚氨酯进行整体封装,聚氨酯层厚度大于1.5mm,可耐受大于20kV的冲击电压。采用高压方波发生器与Pearson4100线圈对罗氏线圈标定。罗氏线圈的参数为:灵敏度0.018 8V/A,最高上升时间小于20ns,方波脉宽300ns,最大峰值电流300A。In this paper,a new self-integral Rogowski coil with magnetic core is designed,which has the advantages of high signal-to-noise ratio and wide dynamic range,for the measurement of nanosecond pulse current signal.It has shielding box open air gaps to prevent the eddy current.The outer layer of the shielding box is packaged with polyurethane encapsulation,and the polyurethane layer has a thickness greater than 1.5 mm,which can withstand more than 20 kV pulse voltage.The Rogowski coil is calibrated using a high-voltage square wave generator and a Pearson 4100 coil.The parameters of the Rogowski coil are:sensitivity 0.018 8 V/A,maximum rise time less than 20 ns,square wave pulse width 300 ns,maximum peak current 300 A.
