Aiming at the problems of high charging voltage of the shock chip detonator in the in-line safety detonation system and it is difficult to meet the requirements of conventional weapons, a multi-functional electric explosion detonation and testing instrument was designed, an explosion foil model was established for simulation, and a low-voltage ignition environment was carried out. The explosion voltage and explosion current test experiments of three explosion foils with the same shape and different materials were used to observe the electric explosion process by using a high-speed camera and an electron microscope. Higher at 1 000 V, it can reach 28.6%, the peak power is larger, and the electric explosion performance is better. Taking low-voltage ignition as the test condition, the detonating instrument verified the electric explosion characteristics of the explosion foils of different materials, which provided a certain reference value for the research on the electric explosion performance of the shock sheet detonator with low energy.
