Description
Изобретение относитс к взрывному устройству, а именно к оптическим устройствам инициировани неконтактных взрывателей. Известен фотоэлектрический взрыва тель, содержащий фотоэлектронный преобразователь, формирующий при его ;облучении потоком света от внешнего источника электрический сигнал подрыва зар да 1. Известна также схема последовательного включени излучателей световых потоков, обеспечивающа одновременное включение всех излучателей от общего источника питани -накопите л электрических зар дов 12. В качестве прототипа данного изоо ретени выбрано взрывное устройство, содержащее подрывной зар д с оптическим взрывателем, соединенным с источником света через световода и источник питани 3. Известные устройства Hie обеспечивают необходимой синхронности подрыва зар да иэ-эа разбросов во времени включени источников света, обусловленных различной длиной линий включени И разбросом пусковых характеристик источников света. Цель изобретени - обеспечение синхронного подрыва зар да путем компенсации вли ни различи длин линий включени и разброса пусковых характеристик источников света. Дл этого в предлагаемом устройстве источники света выполнены в виде последовательно включенных однотипных газоразр дных ламп, зашунтированных резисторами и подключенных к источнику питани через ограничивающий резистор , параллельно которому подсоединен коммутирующий элемент, включающий устройство в режим Взрыв. На фиг. 1 дана структурна схема взрывного устройства с двум подрывными зар дами; на фиг. 2 - электрическа схема источника света. Взрывное устройство (фиг. 1) содержит два идентичных капсюл -воспла.-. менчтел 1, которые содержат подрывной зар д 2 с :расположенной между| ним и световодом 3 линзой 4. Световоды 3 оптически соедин ют капсюливоспламенители 1 с источником 5 света, состо щим в описываемом варианте из двух однотипных газоразр дных пгалп 6, включенных последовательно, зашунтированных резисторами 7 и подключенных к источнику питани 8, выполненному.This invention relates to an explosive device, namely, optical devices for initiating proximity fuses. A photoelectric blaster is known, which contains a photoelectric converter that, when irradiated by a light source from an external source, generates an electrical signal for undermining charge 1. A circuit is also known to sequentially turn on light emitters that simultaneously turn on all emitters from a common power source 12. As a prototype of this invention, an explosive device was chosen that contains a blasting charge with an optical fuse connected to a source 3. The known Hie devices provide for the necessary synchronism of undermining the charge with a wide variation in the time of switching on the light sources caused by different lengths of the switching lines and the spread of the starting characteristics of the light sources. The purpose of the invention is to provide simultaneous detonation of the charge by compensating for the effect of the difference in the lengths of the switching lines and the variation of the starting characteristics of the light sources. To do this, in the proposed device, the light sources are made in the form of series-connected gas-discharge lamps of the same type, shunted by resistors and connected to a power source through a limiting resistor, in parallel with which a switching element is connected that switches the device into Explosion mode. FIG. 1 is given a structural diagram of an explosive device with two blasting charges; in fig. 2 is an electrical diagram of a light source. Explosive device (Fig. 1) contains two identical primers-Vospla .-. Menchtel 1, which contain a charge of blasting 2 s: located between | The optical fiber 3 optically connects the ignition igniter 1 with the light source 5, which consists in the described embodiment of two similar discharge lamps pgpl 6, connected in series, shunted by resistors 7 and connected to the power source 8, made.
