TRIGGERING DEVICE FOR NON-ELECTRIC DETONATOR FOR TUNNEL BLASTING

摘要

The present invention relates to a triggering device for a non-electric detonator for tunnel blasting and, more specifically, to a triggering device for a non-electric detonator for tunnel blasting, which reduces the use amount of a signal tube, which is a detonating fuse used when a triggering device for a non-electric detonator is applied to tunnel and underground excavation sites, to reduce construction costs. Moreover, in the case that leakage voltage is flown from a work site, electricity is not conducted when the leakage voltage is less than a yield voltage of a diac, so a triac is not turned on and current is blocked from following ends to prevent detonation, thereby providing an effect of being safe from leakage current and static electricity. Moreover, a varistor is connected to a detonation circuit and a yield voltage is set as a range of 2,000 to 2,500 V, thereby providing an effect of preventing incorrect detonation caused by thunderstroke. Moreover, one resistor is connected to an input end of a non-electric detonator blaster, thereby providing an effect of checking line connection of the detonating circuit with a resistance measurer. Moreover, two resistors are added to the input end of the non-electric detonator blaster, thereby providing effects of absorbing a shock applied to each device in blasting or inflow of the thunderstroke, and detonating the signal tube of a non-electric detonator without using an electric detonator. According to the present invention, the triggering device for a non-electric detonator comprises an electricity generator, a base blasting line, the non-electric detonator blaster, and the signal tube.;COPYRIGHT KIPO 2018
