The analysis of transverse electromagnetic forces acting on the edges of thin conductors during the flow of large impulse currents is carried out. Using the obtained analytical solutions and numerical modeling, the dependence of these forces on the current rise time to the maximum, configuration, and relative position of the conductors is demonstrated. The studies were carried out for single-wire and multiwire systems of flat conductors with current rise time variation within wide limits. It is shown that, when the current distribution changes from uniform to the corresponding ideal conductivity, the forces decrease by no more than two times. It is also shown that, in a number of cases in the system conductor-ideally conducting screens-there is no dependence of the transverse forces acting on the edges of the conductor on the frequency of the current.

作用在脉冲功率设备的薄扁平导体上的电磁力


对大脉冲电流流过时作用在细导体边缘的横向电磁力进行了分析。利用获得的解析解和数值模型，证明了这些力对电流上升到最大值的时间、导体的配置和相对位置的依赖性。这些研究是针对电流上升时间变化范围较宽的扁平导体的单线和多线系统进行的。结果表明，当电流分布从均匀分布变为相应的理想电导率时，力减少不超过两倍。还表明，在系统导体（理想的导电屏蔽）的许多情况下，作用在导体边缘上的横向力不依赖于电流的频率。
