摘要：
Electrical explosion of wire in liquid can generate shock waves with higher energy efficiency and has been successfully applied in fossil energy development and other fields. However, the explosion requires a mechanism to replace the wire that is prepositioned between the electrodes to address the problem of high frequency operation. Therefore, we propose a wire replacing mechanism based on gallium-indium-tin liquid metal; based on the mechanism, the liquid metal’s fluidity is utilized which is able to quickly and stably form wires between discharge electrodes under low voltage control. During the discharge process, we maintain the same discharge pattern and change the voltage, and we measure the voltage and loop current and calculate the loop parameters and energy. Based on the data, we establish a simulation model to analyze the characteristics of energy conversion of the breakdown time delay and the resistance at the moment of breakdown as a single variable, respectively. The results show that the phase change process of gallium-indium-tin liquid metal wire during the discharge is different from that of ordinary metal wire. The higher the initial charging voltage is, the higher the breakdown resistance of liquid metal wire will be, the shorter the breakdown time delay will be, and the higher the energy conversion efficiency will be. The result is of reference significance for the study of the discharge characteristics of liquid metal wire underwater and the improvement of the application of wire electrical explosion technology in industry. © 2023 Science Press.
