摘要:
分析了高速列车弓网电弧产生的机理，结合受电弓和接触网间的离线时间、材料缺陷、电腐蚀等问题，解析了弓网电弧与高速列车安全的关联机制。依据电弧理论的动态模型算法，推导了Cassie模型和Mayr模型的理论公式，并论述了这两种模型的适用条件和应用范围。提出了高速列车弓网电弧方面目前仍存在的问题及未来电弧研究的展望。
Abstracts:
Through analyzing the mechanism of high-speed train pantograph arc，and combined with the offline time between pantograph and catenary，material defects and electrical corrosion，the correlation mechanism between pantograph arc and high-speed train safety is resolved. Based on the dynamic model algorithm of arc theory，the theoretical formulas of Cassie model and Mayr model are deduced，the applicable conditions and scope of the two models are discussed. This paper puts forward the problems that still exist in the arc of high-speed trains and the prospect of future arc research.
