摘要
为了提高水介质脉冲形成线的储能密度和减小大型加速器的脉冲功率系统几何尺寸 ,实验研究了水在静压力作用下的耐压强度。简要介绍了液体绝缘介质的击穿机理 ,在设计的水介质耐压实验装置上研究了去离子水介质在压力作用下的脉冲击穿特性。结果表明 ,当压强由 0 .1MPa增加到 0 .7MPa时 ,水的击穿场强由 2 5 .3MV/m增加到 4 6 .
This paper presents the mechanism of the breakdown of liquids. Experimental apparatus of pulsed breakdown of the pressured deionized water is set up. The relationship between the pulsed breakdown stress and the water pressure is investigated. The results of test show that breakdown stress is significantly higher than that predicted by currently accepted breakdown criteria when a hydrostatic pressure is applied to the water dielectrics. When the pressure of water changed from 0.1 MPa to 0.7 MPa, breakdown stress of water changed from 25.3 MV/m to 46.7 MV/m. Using the pressured deionized water as dielectrics, the energy density of the energy system could be enhanced notably and the size of the pulsed power system could be minified.
