摘　　要：随着轨道交通、船用电力系统等直流电力系统的迅猛发展,混合型快速直流开断成为了当前电气领域的热点问题。混合型快速直流开断过程中的燃弧有着较为鲜明的特点:短时短间隙。虽然这种短时短间隙电弧现象直接影响着混合型快速直流开断的成功与否,但是就查阅文献的情况来看,其研究还未成体系。该文就该问题进行总结。首先简要地对混合型直流快速开断的电气特性进行介绍,并通过高速摄像较为直观地呈现了短时短间隙电弧现象,在概要总结了开关空气电弧国内外研究进展的基础上,提出了适合于短时短间隙电弧建模及相关研究工作的技术途径建议,最后陈述了前期就短时短间隙电弧所进行的部分工作进展。With the rapid development of DC power system applied in urban rail transportation and ship-borne electricity systems, the hybrid current limiting fuse（HCLF） has become the hot issue in present research on electricity. The arc of HCLF possesses conspicuous characteristics during the current switch on/off procedure, i.e. short time and short gap. Albeit the characteristic of short time and short gap influences the result of the current switch on/off procedure of HCLF, the present studies still haven＇t construct a systematic research on it by the view of the literature. Served as guidance to further researches, this study summarized the problem. First, a brief introduction of electrical characteristics of HCLF was conducted, and a visual presentation of short time and short gap arc was provided by high-speed cameras. Second, based on the summary of domestic and overseas researches on air arc of electrical switch, proposaled concerning model construction of short time and short gap arc and other technical approaches were put forward. In the end, the progress of preliminary works on short time and short gap arc was stated.
