摘要
采用多分支螺线圈型爆磁压缩发生器数值模拟程序MFCG8-7进行理论模拟及参数优化,设计了EMG-125型螺线圈型发生器,并开展了实验研究。电感负载实验结果表明:EMG-125型发生器可以在25nH电感负载上输出大于3 MA脉冲电流,负载能量大于100 kJ,电磁能量放大50倍。
According to the results of the code MFCG8-7 based on the circuit model, an EMG-125 type generator has been designed and tested. The EMG-125 generator is 900 mm in length, 125 mm in diameter, and its charging explosive weighs 2.7 kg. A series of experiments show that, there would be serious breakdowns inside the generator if the input current is beyond the limit of 8 kA （the limit of the input energy is about 2 kJ）. In the case of input current 8 kA, the peak current 3 MA was measured on the inductive load 25 nil, which is 0.3 MA less than the calculated result without magnetic flux losses. The maximal energy on the inductive load is 100 kJ with the peak gain of 50. The calculated results agree with the experimental results when the calibrated coefficient of magnetic flux losses is set as 0.03.
