摘要

在MIG发电机(2.5 MA, 100 ns)上实验研究了平面导体在电流蒙皮模式下发生电爆炸时产生的非线性磁扩散波的传播。磁场感应强度明显大于面对电场的板表面发生爆炸所需的感应强度。选择作为平面导体的负载来观察平板背面等离子体的形成。观察到,在给定的实验条件下,电流开始75ns后,在这一侧,在板的纵轴区域形成了等离子体通道。研究了沟道形成模式与磁场强度和板宽的关系。

Skin Electrical Explosion of Plane Copper Conductors
The propagation of a nonlinear magnetic diffusion wave which arises in an electrical explosion of plane conductors occurring in a current skinning mode was investigated experimentally on a MIG generator (2.5 MA, 100 ns). The magnetic field induction was significantly greater than that necessary for the plate surface facing the electric field to explode. The loads configured as plane conductors were chosen to observe plasma formation on the back side of the plate. It was observed that on this side, under the given experimental conditions, 75 ns after the onset of current flow, a plasma channel formed in the region of the longitudinal axis of the plate. The pattern of channel formation was investigated in relation to the magnetic field strength and the plate width.
