FIELD: blast equipment, applicable in blast breakers of pulse current, magnetocumulative generators with an axial initiation and in other devices, where the electric strength of the device for formation of blast wave is required. ^ SUBSTANCE: the device has an initiation source, explosive charge with branches and the main explosive charge. The charge with branches is made in the form of disks uniformly installed in the axial length of the main charge, alternating with dielectric, the distance between the disks is selected not exceeding value where - time deference of the outlet of the detonation wave to the external surface of the main charge; D - speed of detonation wave of the main charge; - wall thickness of the main charge, the disks from the explosive charge are connected in pairs by rods from explosive charge, which in turn are interconnected by radial and longitudinal cross-pieces from explosive charge and positioned on one side from the charge axis, and a passage with explosive charge connected to the cross-piece and brought out to the initiation source located on the charge end face is positioned on the other side. The quantity of connections of disks alternating with dielectric may be changed depending on the length of the main explosive charge and maintenance of distance S between the disks. The device is made with an adjustable delay of operation. ^ EFFECT: provided simultaneous blasting of the main cylindrical charge with initiation in its axis with an enhanced electric strength. ^ 2 cl, 2 dwg |
