中文摘要：
为防止弓网电弧侵蚀受电弓和接触网，避免其对机车设备和环境的电气干扰，保证机车可靠受流，针对电气化铁路及城市轨道交通的弓网电弧问题，从电气特性角度进行研究进展综述。首先，讨论弓网电弧的产生机理，归纳电弧的各种数学模型和弓网电弧特点。同时，从高速铁路弓网电弧的电气特性人手介绍当前国内外弓网电弧的电气侵蚀、电弧能量、电气干扰和电弧检测的最新研究进展。最后从电气特性角度，指出弓网电弧研究存在的问题和未来发展趋势。
英文摘要：
From the angle of electrical characteristics, this paper reviewed the research progresses of electric arcs between pantograph and catenary which have been made in order to avoid arc erosion of pantographs ＆ catenar- ies, prevent electrical interference in locomotive equipment and environments and ensure reliable power supply for the electric locomotive. The generating mechanisms of electric arcs between pantographs and catenaries were analyzed. The various mathematical models and characteristics of pantograph-catenary arcs were summa- rized. The introduction in terms of electrical characteristics covers the latest domestic and overseas, research de- velopment of arc erosion, arc energy, electrical interference, arc detection and so on, points out problems existing in present researches and also explains the trend of future research development.
