摘　　要：通过设计一套新型弓网离线电弧模拟发生试验装置,在实验室条件下模拟弓网在实际运行中产生的离线电弧,研究弓网燃弧离线位置对牵引系统过电压的影响规律,提出相应的消弧措施并通过Matlab/Simulink仿真软件对消弧过程进行动态仿真,分析了离线电弧电压特性及放电过程,探究了弓网离线特性与电弧的关系,为改善弓网关系提供参考方案。On the basis of simulation of off-line arc generated during the actual operation of the pantograph-catenary system under conditions by means of specially designed a new type of test device for pantograph-catenary off-line arc simulation and generation,the paper studies the regularities of the impact to the traction system overvoltage caused by the pantograph arc burning and off-line position,puts forward the corresponding measures of arc suppression and carries out dynamic simulation of arc suppression process by Matlab/Simulink simulation software,analyzes the off-line arc voltage characteristics and discharge process,and explores the relationship between the pantograph-catenary offline characteristics and the arc,so as to provide reference schemes for improving the relationship between pantograph and catenary.
