Description

technical field [0001] The invention relates to a device for testing the volt-ampere characteristics of an electric explosion foil of an impact chip detonator, in particular to a device for testing the volt-ampere characteristics of an electric explosion foil with adjustable voltage segments and a charging and discharging method. Background technique [0002] The electro-explosive foil is the key component of the shock-plate detonator, and its electric-explosive performance is directly related to the reliability and safety of the shock-plate detonator. When conducting the electric explosion performance test of the electric explosion foil, it is necessary to use a volt-ampere characteristic test device to charge and discharge (first charge the high-voltage capacitor, and then control the high-voltage capacitor to discharge the electric explosion foil), so that the electric explosion foil is detonated. The traditional volt-ampere characteristic test device mainly includes two ...
