Abstract
The invention relates to a single-capacitor electronic detonator () comprising an explosive-initiating means (), electronic control means () and a single energy storage capacitor () for supplying the electronic control means () and the explosive-initiating means () with power when firing the single-capacitor electronic detonator (). It further comprises means () for clipping the voltage across the terminals of the single energy storage capacitor () to a value lower than a non-firing voltage value (Ua) of the explosive-initiating means (), and voltage-regulating means () connected to means () for connecting to a power source (), 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 (). The invention also relates to the use thereof in a firing system to improve safety when using single-capacitor electronic detonators ().
