摘　　要：利用Matlab软件的Simulink仿真环境，创建了高压脉冲大电流测量系统的仿真模型，实现对罗氏线圈结构参数的确立和积分器积分常数的优化。给出了一种适合于高压脉冲大电流测量的罗氏线圈的结构设计及其积分电路的设计方法，并将这种测量装置成功应用到脉冲成形网络（PFN）放电系统中。通过在积分电路中加入滤波抗干扰设计，实现了对高压脉冲大电流的测量，克服了冲击电流测量中常规用分流器存在的问题和不足。The simulation model of high-voltage pulsed current measurement systems is presented through simulating in simulink of matlab. Using this model, the structural parameters of Rogowski coil are designed and the integral constants of integraph are optimized. Moreover, the methods of designing the structure of Rogowski coil and the integral circuits are presented to measure the high-voltage pulsed current. Applying these methods to the PFN discharge systems and designing the filter for the integral circuit, the measurement of high-voltage pulsed current is became effectively and the limitation in conventional shunt of impact current measurement is overcomed.
