Description
Technical field
The utility model belongs to explosive and priming system technical field, relates to the detonator that a kind of electronics extension or digital electric are delayed and adopted the Semiconductor Bridge Ignition mode.
Background technology
Commercial electric detonator or engineering electric cap mainly are made up of electric igniting element, delay element and basal detonator, the used electric igniting element of tradition detonator generally adopts the thermal bridge wire type point of amorce, i.e. energising back heat bridge silk heating, convert electrical energy into heat energy, and pass to the ignition charge that is coated on the bridge silk, when reaching the flashing temperature of ignition charge, the ignition charge burning, thus realize igniting.The used delay element of tradition detonator generally adopts pyrotechnic compound extension mode, promptly after igniting element was got angry, the pyrotechnic compound burning in the smoke postpone body (as plumbous rope extension body, interior tubular type extension body etc.) was by realizing extension burning time, act on basal detonator during all burnt, make blasting cap detonation.
Because the delay precision of the pyrotechnics class delay element that adopts in traditional detonator is relatively poor, it is also relatively poor to store back extension stability, the extension section that can realize is not limited, " hybrid electronic detonator delay circuit assembly " that Chinese patent description of the invention notification number CN1245558A provides, " the programmable electronic detonator delay initiation system " that Chinese patent utility model specification notification number CN201191166Y provides, " adjustable electronic detonator control chip and the control flow thereof " that Chinese patent description of the invention notification number CN101586931A provides, " a kind of intrinsic safety type electric detonator detonation system " that Chinese patent description of the invention notification number CN101408397A provides, " a kind of novel digital electronic detonator and the control method thereof " that Chinese patent description of the invention notification number CN101666596A provides, all adopt delay circuit to replace traditional pyrotechnic compound time-delay mode, improve the delay precision and the stability of detonator greatly, and increased the not available detonator identification of traditional detonator, security functions such as password detonates.Because this type of electric detonator is still adopting heat bridge silk point of amorce through the igniting behind the electronic delay, although the electronic delay precision is very high, but have bigger scattered band action time because point of amorce is got angry, the delay precision of electric detonator depends primarily on precision action time of point of amorce at present.In order to improve precision action time of point of amorce, the researcher adopts responsive more ignition powders, has reduced the security of production process so again, and even so, its, extreme difference also can only be controlled at about 1ms action time.
Because stability and the uniformity of the thermal bridge wire type point of amorce ignition action time that traditional detonator adopted are relatively poor, and point of amorce is very sensitive, antistatic, stray electrical poor performance easily cause burning, explosion accident in the production use, have the researcher to study new electric ignition mode.For example, " a kind of method of igniting detonator and the device " that " semiconductor electric detonator ", the CN1749688A that Chinese patent description of the invention bulletin CN1749686A provides provides, " a kind of device of igniting detonator " that Chinese patent utility model specification notification number CN2847209Y provides, all adopt Semiconductor Bridge Ignition, the ignition action time is less than 5 μ S, wink, degree of sending out was high, and do not use ignition charge, improved the security of production use greatly.But this invention detonator is mainly used in instantaneous cap, and when delay detonator adopted the smoke postpone element, because its burning air chamber is little, delay precision was poorer than traditional detonator.In addition, though have very strong antistatic effect between semiconductor electric detonator payment to a porter and shell, the antistatic and anti-stray electrical ability between its two payment to a porter is not strong.Therefore, semiconductor electric detonator is applied as yet so far.
