(EN) SINGLE-CAPACITOR ELECTRONIC DETONATOR AND SYSTEM FOR FIRING SUCH SINGLE-CAPACITOR ELECTRONIC DETONATORS

(EN)

The invention relates to a single-capacitor electronic detonator (10) comprising an explosive-initiating means (11), electronic control means (16) and a single energy storage capacitor (15) for supplying the electronic control means (16) and the explosive-initiating means (11) with power when firing the single-capacitor electronic detonator (10). It further comprises means (18) for clipping the voltage across the terminals of the single energy storage capacitor (14) to a value lower than a non-firing voltage value (Ua) of the explosive-initiating means (11), and voltage-regulating means (19) connected to means (13) for connecting to a power source (12), which means are suitable for limiting the output voltage to a value lower than a non-firing voltage value (Ua) of the explosive-initiating means (11). The invention also relates to the use thereof in a firing system to improve safety when using single-capacitor electronic detonators (10).
