N2 - Pulse discharge in water can not only produce ozone, hydrogen peroxide and other active substances with high oxidation potential, but also ultraviolet light and shockwaves, which has been widely used in biomedical, environmental, mining and other fields in recent years. The formation of active substances in water is closely related to the formation characteristics of discharge channels in the process of pulse discharge, as a result of which it is of great importance to study the characteristics of discharge channels in water for further development of high voltage pulse discharge technology. In this study, pulsed voltage produced by Marx pulse generator with frequency set to be 1Hz is applied for analyze characteristics of discharge channels induced by pulsed discharge in water. With the increase of voltage amplitude, transition of discharge mode from streamer discharge to spark breakdown is realized. Based on the fundamental results of discharge channels, preliminary experiments of its application in solar panel recycling are performed, which show that high voltage fragmentation is an effective method to deal with solar panels and the optimal parameter is 193J/g imported in this research. Circular holes and dendritic discharge channels are formed on the surface of the back sheets, and the ablation on the surface of the back plates shows a rugged pore structure on the micro level. Main metals in the broken products are concentrated in specific size fractions, which is convenient for resource recovery.
