摘要

提出了利用Nd2Fe14B高能硬铁磁体的横激波退磁效应为炸药驱动的螺旋磁通压缩发生器(FCG)提供动力的新应用。设计、构建并试验了一种新型的基于紧凑型横波铁磁发生器(FMG)的新型横波铁磁发生器，该发生器包含200-cm3的载能元件Nd2Fe14B和12 g高爆装药。提出的设计是基于FMG的宽同轴单匝脉冲产生线圈可以同时作为FMG的种子线圈的想法。将FMG的同轴单匝脉冲发生器线圈缠绕在FMG螺旋的起始部分;因此，FMG的脉冲产生系统与FMG的螺旋之间只存在变压器耦合。该播种系统为螺旋FCG提供高达180 A的电流振幅和55 μ s的电流脉冲持续时间。

Transformer-Type Seeding System of a Helical FCG Based on a Transverse Shock Wave Ferromagnetic Generator

A new application of the effect of transverse-shock-wave demagnetization of Nd2Fe14B high-energy hard ferromagnets for powering an explosive-driven helical flux compression generator (FCG) is proposed. The novel FCG seeding system based on a compact transverse shock-wave ferromagnetic generator (FMG) containing a 200-cm3 Nd2Fe14B energy-carrying element and a 12 g high explosive charge was designed, constructed, and tested. The proposed design is based on the idea that the wide coaxial single-turn pulse-generating coil of the FMG can simultaneously serve as a seed coil for the FCG. The coaxial single-turn pulse-generating coil of the FMG was wound on the initial part of the FCG helix; therefore, only transformer coupling existed between the pulse-generating system of the FMG and the helix of the FCG. This seeding system provides up to 180 A current amplitude and 55 mus current pulse duration to a helical FCG.
