Description

technical field [0001] The invention relates to the technical field of civil explosion, in particular to a high-voltage electric pulse ignition type electronic detonator. Background technique [0002] While the industry is fully promoting electronic detonators, the existing problems of electronic detonators are gradually emerging. At present, the main problems of digital electronic detonators are: First, the ignition components, electronic control modules, and energy storage capacitors are all set inside the basic detonator. The space is severely limited, and the volume of the components is constrained, thus limiting the capacity of the energy storage capacitors; second, At present, the ignition element of electronic detonator is composed of bridge wire and ignition agent. During production and use, the ignition element is energized during detection, which may cause the ignition agent attached to the ignition element to burn and then detonate the detonator, causing potential...

AI Technical Summary

Problems solved by technology

At present, the main problems of digital electronic detonators are: first, the ignition parts, electronic control modules, and energy storage capacitors are all arranged inside the basic detonator, and the space is severely limited, which restricts the volume of components, thereby limiting the capacity of energy storage capacitors; At present, the ignition part of the electronic detonator is composed of a bridge wire and an ignition agent. During the production and use process, the ignition element is energized during the inspection, which may cause the ignition agent attached to the ignition element to burn and then detonate the detonator, causing a safety hazard; the third is the ignition element of the electronic detonator Pyrotechnic powder is required to detonate the detonator, and the production process of pyrotechnic powder is complex and cumbersome, and most of them require manual operation and handling. Pyrotechnic powder requires a drying workshop or large-scale drying equipment, which takes a long time to dry, not only occupying space, but also consuming energy It is also high, which also makes it impossible to realize the automatic production of the whole line at present; the third is that the traditional electronic ignition components are used in small sections, foundation pits and other operating environments, because the blast hole that explodes first when the front low-delay detonator blasts the blast hole produces high energy and high The extrusion caused by high-frequency instantaneous vibration and rock cracking can easily cause the ignition bridge wire of the electronic ignition element of the high-delay detonator to break and the ignition powder ball attached to the ignition bridge wire to fall off or rupture, and then cause the problem of blast rejection, causing great hidden dangers to the construction Wait
