爆磁压缩发生器的耦合损耗因子研究

Study on Coupling Loss Factor of Magnetic Flux Compression Generator

小型爆磁压缩发生器击穿、跳匝、接触磁通损失及电阻损耗现象难以避免,其中磁通损耗和电阻损耗对未知结构发生器的影响不是线性的,使得发生器的运行结果难以预测。以一种解耦的爆磁压缩发生器运行模型为研究对象,提出了磁通损耗项和电阻损耗项的耦合损耗因子解析式,并给出了明确的物理意义。与实验数据对比表明:考虑了上述损耗因子的模型可以预测未知结构发生器的运行结果且与实验结果吻合较好。

The phenomena of breakdown,turn-skipping,contact the magnetic flux and resistance losses in small explosive magnetic flux compression generator are inevitable,in which the influences of flux and resistance losses on unknown structure generator are not linear,therefore it is still a difficulty to determine the results that the generator runs.An analytic solution for the coupling loss factor between flux loss item and resistance loss item was proposed by researching the operation model of a decoupled explosive magnetic flux compression generator,and the clear physical meaning was given.The comparisan between the simulated result and the experimented data shows that the model which takes the above loss factors into account can predict the running results of unknown structure generator,and the simulated result is in approximate coincidence with the experimented result.
