摘要

摘要: 水介质的绝缘性能影响脉冲功率装置的运行状态，水中气泡是引起水介质击穿的主要因素。为去除水介质中的气泡和溶解性气体，分析了水介质中产生气泡的原因，针对水介质中的体相气泡和表面吸附气泡去除问题，比较了涡流式分离器和反渗透膜的脱气方法，并对其气泡脱除性能进行实验研究。研究结果表明，涡流式分离器的旋流强度低造成分离效率较低，反渗透膜脱气通过降低气体在水中的溶解度使得表面吸附气泡重新溶解，分离效率较高，可以去除水中气泡和溶解性气体，对脉冲功率装置的稳定运行具有重要意义。

Abstract: The insulating property of water medium affects the operation status of pulse power device, and air bubbles in water are the main factor causing breakdown of water medium. In order to remove air bubbles and dissolved gases in the water medium, the causes of air bubbles in the water medium are analyzed, and for the removal of body-phase air bubbles and surface adsorption air bubbles in the water medium, the methods of removing air bubbles by using vortex separators and reverse osmosis membranes are compared, and experimental research is carried out to study the performance of their air bubble removal. The results show that the vortex separator's low cyclonic strength leads to low separation efficiency, and the reverse osmosis membrane degassing makes the surface adsorbed bubbles re-dissolve by reducing the solubility of the gas in the water, and the separation efficiency is high, which can remove the gas bubbles and dissolved gases in the water, and it is of great significance for the stable operation of the pulsed power device.
