To enhance the shock wave generated by underwater electrical wire explosion(UEWE),wires are connected in parallel to form wire-array,but wire-array's low resistance results in low deposition power.To solve the problem,by using copper sheets,parallel-series wire-arrays with different resistance and same mass were designed,and it was proposed that resistance matching between wire-array and power source is the ideal discharge mode.By parallel-series wire-array,single wire discharge similarity was verified,and miniaturization verification of large devices with high voltage was achieved.With the help of discharge similarity and parallel-series wire-array,the optimal wire-array design of UEWE was proposed at a given energy and wire mass.
