摘要: 脉冲功率科学与技术广泛应用于X射线闪光照相、惯性约束聚变(ICF) 和高能量密度物理等研究领域，其基本特征是将能量在时间和空间上进行压缩来获得极高的功率密度，进而获得高温、高压、强辐射和高能量密度的极端条件。大型脉冲功率装置是获得高功率脉冲的载体，真空功率传输系统是此类装置的重要组成部分，是将储能系统的能量传递给负载的关键，也是决定大型脉冲功率系统技术可行性的重要方面。分析了大型脉冲功率系统真空功率传输的物理基础，综述了相关物理问题的国内外研究状况，结合Z箍缩聚变驱动器特定的需求，具体分析了技术现状与目标的差距，最后针对后续研究提出了建议和看法。Abstract: The basic characteristic of the pulsed power science and technology, which is widely applied to X-ray radiography, inertial confinement fusion and high energy density physics, is energy compressing, both temporally and spatially, to obtain high power density and extreme conditions in temperature, pressure and radiation. Vacuum power flow components are decisive for pulsed power systems. Physical fundamentals, key issues and researching status for vacuum power flow around the world are surveyed in this paper. The gap between object and status is analyzed for vacuum power flow investigations for Z-pinch fusion driver. Opinions and researching suggestions are presented.
