Electroexplosive current commutation. The coupling of parameters of inductive-capacitive storages and loads

Summary form only given, as follows. In previous research of electroexplosive, commutation of high currents the real and limiting characteristics of opening switches in a mode of "idle" explosions of conductors in arc-quenching media were studied. It was shown, that the development of ionizing phenomena and the ignition of the shunting discharge in a boundary area between exploded conductors and environment, prevent achieving high voltage pulses. These undesirable phenomena can be suppressed by the energetic optimization of explosive process and the use of effective arc-quenching media. In the present work the questions connected with using electroexplosive opening switches for commutation of high currents to physical loads with various mechanisms of energy absorption are studied. The crux of the problem of parameter coupling is that up to the moment of switching on a load to energy storage the electrical explosions should go in a mode of "idle" explosion, as the maximum stored specific, magnetic energy should essentially exceed the sublimation energy. In this mode the danger of the development of ionizing phenomena and the ignition of the shunting discharge is great. The connection of load reduces the input of energy in the opening switch and the development of these phenomena decreases. However earlier connection can brake the process of the loss of metal electrical conductivity and worsen switching characteristics. In the given report the results of numerical optimization for the process of the connection of various loads to inductive-capacitive storages are informed. The comparison of results with experimental data received on various installations will be carried out.
