摘要
根据爆磁压缩发生器中导电体工作条件, 对比了电枢和含铝炸药爆轰产物作为导电体的异同, 得出几种高电导率含铝炸药爆轰产物对应的磁雷诺数, 分析了含铝炸药爆轰产物代替电枢压缩磁场的可能性。设计了一种含铝炸药爆轰产物导电式螺线型爆磁压缩发生器, 分析其运行过程, 得出等效电路模型。数值模拟结果表明:相比于电枢作为导电体的传统螺线型爆磁压缩发生器, 同体积条件下高电导率含铝炸药爆轰产物导电式爆磁压缩发生器具有更好的输出性能;该设计可以有效地抑制跳匝、电枢与定子线圈短路点接触不良等容易引起磁通损失的问题。
Abstract
Armature and aluminized explosives detonation products were compared based on the conductor working condition of flux compression generators. Detonation conductivity of some mixed explosives was summed up, whose magnetic Reynolds numbers were calculated, and the possibility of using detonation products of high conductivity instead of armature to compress magnetic flux was analyzed. A modified design of helical flux compression generator utilizing detonation products to compress flux was proposed, whose running process and equivalent circuit were acquired. Simulation results indicate that the modified design has a better output performance than the traditional one of the same volume. Furthermore, the modified design is simpler, and some problems such as turn-skipping and flux losses of armature-stator contact can be avoided.
