Abstract

The performance of exploding bridgewire detonators affected by electrostatic discharge (ESD) were studied by microfocus X-ray industrial computed tomography (μCT), and high voltage stimulus to detonators was provided by an ESD simulator. Two stimulation modes were investigated, and the performance indexes of detonators after ESD were tested. The results show that there was no obvious change in bridge resistance when detonators were simulated by the mode of Pin-Pin, while the primary explosive of detonators was partly damaged by the mode of pin-shell, and the performance indexes of 2 detonators were affected by ESD. The reasons for this phenomenon were analyzed. This work contributes to understanding the performance of exploding bridgewire detonators affected by ESD.
