FIRING DEVICE FOR ELECTRIC DETONATOR, BLASTING APPARATUS HAVING THE SAME AND FIRING METHOD FOR ELECTRIC DETONATOR

摘要

invention detonators , blasting devices, and it includes an electric detonator tube detonator way of that , the trigger mechanism is controlled to the input voltage is applied jimyeo zener diode and a transistor , the current generation unit is arranged to generate a constant current by the input voltage , the transistor is controlled in connection with the current generated by the current generation section trigger signal , When the circuit part, and is connected to the current generation section receives a load signal so that the aeration tube detonator after loading and a relay circuit which is switched so as to conductive parts of the detonator tube and the current generation . Through this , the reliability can be improved detonator , electric detonators and detonating detonator tolerance ways to disarm the detonator tube by a constant current is implemented . ;
