| 摘 要： | 气体火花开关是脉冲功率装置中最常用的关键器件。电极烧蚀作为脉冲功率开关中的难点问题，会引起开关自击穿电压降低、触发抖动增大及开关寿命降低，已成为制约气体开关发展和应用的一个瓶颈。本文回顾梳理了国内外学者针对电极烧蚀问题进行的一系列研究，从电极烧蚀理论和实验研究成果两个方面，介绍了电极烧蚀的基本机制及仿真模型，归纳了影响开关电极烧蚀的因素以及电极耐烧蚀材料的研究进展，最后讨论了电极烧蚀研究面临的问题以及优化电极材料抗烧蚀性能的方向。

| Abstract: | Gas spark switch is the most commonly used key device in pulse power device. The difficult problem of electrode erosion, which affects the performance of gas spark switches, has always become a bottleneck restricting the development and application of gas switch. This article reviews the existing electrode erosion theory and experimental research results, introduces the basic mechanism and simulation model of electrode erosion, summarizes the factors affecting the switching electrode erosion and the research progress of erosion-resistant electrode materials, and finally discusses the problems faced by the erosion research and the direction of optimizing the erosion resistance of the electrode materials. |
