The device 8 and the coil 6 are fed with 300KHZ alternating current to induce the metal post 5. The metal post 5 generates heat under the action of high-frequency current conversion, and according to the skin effect, the heat is concentrated on the surface of the metal post to form a high temperature rapidly, and the metal post ignites. 5 contact with the priming charge 3, the metal post 5 as the medium for detonating the priming charge 3 is always out of contact with the external circuit, so it will not cause accidents due to static electricity generated by transportation, movement, etc., and the detonator shell 1 and the insulating base 4 are all Insulation material, will not cause accidental explosion due to collision and sparks.
工作原理：一种感应起爆系统，利用高频交流电发生器8产生的高频交变电场对金属柱5进行感应加热，集肤效应使金属柱5表面的温度瞬间升高从而达到引燃起爆药进而引爆雷管，线圈6以及相关电路均不与起爆药3直接接触，可以有效防止静电等引起误爆，并且雷雨天气、静电和施爆区域的工频电路很难影响金属柱5的升温，本发明提出的一种感应起爆系统结构简单，成本低廉并且便于运输和存储，对于雷管的安装和引爆的安全性及稳定性也得到了极大的提升。Working principle: an induction detonation system, which uses the high-frequency alternating electric field generated by the high-frequency alternating current generator 8 to inductively heat the metal column 5, and the skin effect makes the temperature on the surface of the metal column 5 rise instantaneously to ignite the detonating charge. Then, when the detonator is detonated, the coil 6 and related circuits are not in direct contact with the primer 3, which can effectively prevent static electricity from causing accidental detonation, and thunderstorm weather, static electricity, and power frequency circuits in the blasting area are difficult to affect the temperature rise of the metal column 5. The induction detonation system proposed by the invention is simple in structure, low in cost, convenient for transportation and storage, and greatly improves the safety and stability of the installation and detonation of the detonator.
