摘　　要：随着高功率脉冲电源(Pulse Power Supply)在电磁轨道炮、电磁弹射器及电磁推射装置中的广泛应用,对其产生的脉冲大电流的精确测量显得尤为重要,但目前电流测试领域常用的测试方法由于稳定性不足、量程有限、测量精度不高等缺陷,无法满足具有兆安级放电电流的高功率脉冲电源的测试需求。因此,提出了一种基于罗氏线圈和积分器的超大电流测试技术。首先通过COMSOL有限元分析软件的AC/DC磁场模块建立模型对该电磁环境进行仿真分析,以确定采集系统在该电磁环境中的安全测试距离,并对罗氏线圈和积分器的测试原理做了具体说明,最后搭建硬件平台在实际的试验中证明该方案能够实现对兆安级脉冲大电流的测试,论证了该测试方法的可行性。With the wide application of high power pps(Pulse Power Supply)in electromagnetic rail gun,electromagnetic ejector and electromagnetic thruster,it is very important to accurately measure the pulse current generated by high power pulse power supply. However,the current testing methods commonly used in the field of current measurement can not meet the testing requirements of high power pulse power supply with megaampere discharge current due to its shortcomings such as insufficient stability,limited measurement range and low measurement precision. Therefore,a super-large current measurement technique based on Rogowski Coil and integrator is proposed. Firstly,the electromagnetic environment is simulated and analyzed by using the AC/DC magnetic field module of COMSOL finite element analysis software to determine the safe testing distance of the acquisition system in the electromagnetic environment. The testing principle of Rockwell coil and integrator is explained in detail. Finally,the hardware platform is built to prove that the scheme can realize the test of large pulse current of megaampere class,and the feasibility of this test method is proved.
