Description
technical field [0001] The invention belongs to the fields of high voltage technology and pulse power technology, and more specifically relates to a liquid electric pulse shock wave generating device. Background technique [0002] Applying pulsed high pressure to two electrodes in the liquid will form a high temperature and high pressure plasma, and the rapid expansion of the plasma can form a pulsed pressure wave, that is, a pulsed shock wave. Shock wave characteristics are mainly related to circuit parameters, discharge voltage and inter-electrode gap. At present, the conventional generation method of pulse shock wave is to adopt multiple half-wave oscillation discharge of current. The discharge time of this discharge method is long. The wave mechanical energy has less energy and correspondingly, the shock wave intensity is lower. [0003] In the existing pulse shock wave technology, considering the dispersion of the breakdown voltage when using liquid discharge, and at ...
