Электровзрывной размыкатель тока для быстрого вывода энергии из индуктивного накопителя в нагрузку

Abstract

The paper presents the results of model testing of the electrically exploded current interrupter (switch) designed for the switching system used to release the electromagnetic energy from the inductive storage to the load through a closing switch-discharger. A capacitor bank was used as a source of energy for the inductive storage. Some features of the discharger were varied in order to increase its reliability and operation speed. The obtained experimental data allowed making recommendations on practical implementation of the opening switch. The optimized version demonstrated a possibility to form current pulses with submicrosecond rise time, up to ~ 100 ns, in the low-impedance loads of the inductive storages. The obtained result is true for the currents of megaampere and multimegaampere level that makes it possible to use the opening switch for commutation of the energy sources with high energy capacity, for example, of the explosive magnetic generators.
