FIELD: high-current switching equipment. ;SUBSTANCE: invention relates to high-current switching equipment and can be used to generate current pulses with a submicrosecond rise front in loads of inductive storage devices for electromagnetic energy. The method consists in breaking the circuit of the inductive storage and closing the storage to the load using a spark gap with interelectrode insulation made of a condensed dielectric pierced by an electric voltage pulse generated when the circuit of the inductive storage is broken. The breakdown is carried out in the mode of localized amplification of the electric field strength in the near-cathode zone of the condensed dielectric and a breakdown delay is created against the background of a surge in the interelectrode potential difference when the inductive storage circuit is broken. In this case, solid non-polar dielectrics, such as polyethylene or polystyrene, as well as liquid dielectrics, such as highly refined electrical insulating oils, are used as the condensed dielectric. Additionally, the liquid dielectric can be sonicated. ;EFFECT: invention reduces the rising edge of the current switched from the inductive storage of electromagnetic energy to the load, the spread of the breakdown voltage of the spark gap insulation.;4 cl, 4 dwg
