EXPLODING-WIRE CURRENT RELEASE Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: release has current-supply electrodes, hollow exploding conductor, explosive material charge with initiator, and electric barrier provided with annular duct opposite to exploding conductor. Hollow exploding conductor is essentially spiral with tightly fitted together and electrically interconnected turns. Release has insulating rod placed along explosive material charge axis. Insulating rod may be made, for example, in the form of two coaxially arranged cylinders with space between them filled with explosive material; initiator is placed in center of explosive charge between cylinders. In addition, annular duct in insulation may be filled with dispersion insulating medium. EFFECT: reduced mass of explosive charge. 3 dwg
