Description

本发明是一种可排除意外爆炸危险的安全电雷管,属于国际专利分类表的F-42C类。 The present invention is an preclude accidental explosion hazard security electric detonators, F-42C class is an international patent classification table. 能取代现用各种电雷管和非电雷管,用于各种爆破工程之中,使爆破工作更加安全。 To replace the current use of various non-electric detonators and electric detonators, used in a variety of blasting, the blasting work safer.

目前国内外用于爆破的电雷管,其结构一般由电雷管脚线、桥丝、引火头、延期药及正副装药等几部分组成。 At home and abroad for electric blasting detonator, the detonator structure generally foot line, bridge wire, fuse head, and vice parts Charge delay composition and other components. 为防杂散电流危害,也有低电阻桥丝结构电雷管和无桥丝结构电雷管。 To prevent stray current hazard, there are low-resistance bridge wire detonator structures and non-electric detonator bridge wire structure. 这些电雷管共同存在的缺点是抗杂散电流的能力差,往往因受到周围环境的静电、雷电、射频电的影响而产生意外爆炸,没有从根本上解决电雷管的安全问题。 These electric detonators co-existing disadvantage is the poor ability of anti-stray current, often due to the surrounding environment by static electricity, lightning effects, the RF power generated by accidental explosion, does not solve security problems electric detonators fundamentally.

为解决电雷管的安全问题,使之能抵御各种交、直流杂散电流以及静电、雷电、射频电的危害,提出本发明的BJ-1型安全电雷管本发明的BJ-1型安全电雷管的结构如图1所示,是由电雷管脚线〔1〕、安全变换电路〔2〕电雷管桥丝及引火头〔3〕、延期药〔4〕及雷管的正、副装药〔5〕所组成。 To solve the security problems detonator, so that it can withstand a variety of AC and DC stray currents and static electricity, lightning, radio frequency electrical hazards presented BJ-1 Safety Safety BJ-1 electric detonator of the present invention, the present invention n, the structure of the sub-charge detonator shown in Figure 1, by the electric detonator foot line [1], [2] safety conversion circuit bridge wire detonator fuse head and [3], [4] and the delay composition detonator [5] composed.

本发明的特征在于是在普通电雷管的发火部分引入了一个安全变换电路〔2〕,其原理及结构如图2所示,类似于变压器结构的感应电路,是由与电雷管脚线联接的一次绕组〔6〕、小磁环变换器〔7〕以及与电雷管桥丝形成无极环路的二次绕组〔8〕所组成。 Thus features of the invention incorporated in the igniting portion of an ordinary electric detonator safety converting circuit [2], the principle and the structure shown in Figure 2, similar to the sensing circuit of the transformer structure, is electrically coupled detonator foot line [6] of the primary winding, a small ring (7) and a transducer electrical detonator bridge wire loop forming the secondary winding Promise (8) formed. 小磁环变换器〔7〕采用软磁铁氧体材质,它具有频率选择特性,利用它做变换电路的铁芯起到隔离低频的交流杂散电流和直流杂散电流的作用。 [7] Small magnetic transducer using ferrite material, which has a frequency selection characteristic, use it to do the conversion circuit core functions stray current AC and DC stray current of a low frequency isolation. 软磁铁氧体小磁环的尺寸较小,外径为5~7毫米,内径为2.5-4毫米,壁厚为1.5~2毫米的小磁环二个,可以置于普通电雷管之内,与电雷管形成一体。 Small ferrite ring smaller in size, an outer diameter of 5-7 mm, an inner diameter of 2.5-4 mm, a wall thickness of 1.5 to 2 mm in two small magnetic ring may be disposed within the ordinary electric detonators, integrally formed with the electric detonator.

本发明的BJ-1安全电雷管工作时,需采用特定频率的高频电流(如15千赫芝)的起爆器接通电雷管脚线,如图2所示,当高频电流i1流经电雷管脚线即一次绕组时,通过软磁铁氧体变换器在二次绕组中产生感应电流i2,i2作用于电雷管桥丝产生足够的热能而将电雷管引爆。 BJ-1 detonator Security work, requires the use of high frequency current of a specific frequency according to the present invention (e.g., 15 kHz Chi) connected to electric detonator detonator foot line, shown in Figure 2, when the high frequency current i1 flows when the foot line via electrical detonator i.e. primary winding current i2 is induced in the secondary winding by the ferrite transformer, i2 generate sufficient thermal energy to effect electrical detonator bridge wire and electric detonators. 直流电或工频交流电进入电雷管脚线时,即使大到数十安培,也无法将电雷管引爆。 When direct current or frequency alternating current into the electric detonator foot line, even as large as tens of amperes, can not be electric detonators. 静电、雷电或无线电波由于产生感生电流小或是瞬时低频电流都难以使本发明的电雷管引爆。 Static electricity, radio waves or due to the lightning induced current produces a small or low-frequency current is difficult to make an instantaneous electric detonator to detonate the present invention.

本发明的BJ-1型安全电雷管具有与现用的非电起爆器材相同的安全性,用于地下爆破时不必停电作业,有利于提高矿山生产的安全效益和经济效益。 BJ-1 Safety electric detonator of the present invention has the active material non-electric initiation same security, you do not have power for underground blasting operation, help to improve the safety of mine production and economic benefits. 其与非电爆器材相比可以进行产品检测,有利于提高爆破工程的可靠性及减少爆破器材的消耗。 Compared with their non-electric blasting equipment product testing can be carried out, it will help improve the reliability of blasting and blasting equipment to reduce consumption. 由于所加安全变换电路成本低廉,使本发明的安全电雷管与普通电雷管的制造成本基本相等。 Added security because of its low cost conversion circuit, the manufacturing cost of security and electric detonator of the present invention is substantially equal to the ordinary electric detonator. 可广泛用于各种爆破工程中,尤其适用于地下爆破工程以及杂散电流、静电等危害严重的场所。 It can be widely used in a variety of blasting works, especially for serious harm places underground blasting and stray current, static electricity and so on.
