FIELD: electricity; demolition works. ^ SUBSTANCE: in facility, containing pyrocartridges with two fibres every of which is shunted by semiconductor device of reconditioning electric circuit continuity with passing from condition closed to open, commutating assemblies of control and disruption current, and also monitoring element, every commutating assembly is implemented on two key element. At that every key element is implemented on field-effect transistor and has two input, the first of which is cut in ground testing equipment, and the second input is cut in on-board control system. The first fibers of every pyrocartridge are connected in series to each other, the second fibers are also connected in series. The first key elements are connected between power supply positive side and inputs of fibers series circuit of pyrocartridge, and seconds - between negative side of power supply and outlets of fibers series circuit of pyrocartridge. Control element is implemented in the shape of transformer, the first input winding of which is connected serially with the first fibers of pyrocartridges, and the second - with the second fibers of pyrocartridges, output winding is control output of facility. ^ EFFECT: improving of coefficient of efficiency and design simplification. ^ 3 dwg |
