高速电气化铁路中的弓网电弧现象研究综述

Research Review of Arc Phenomenon between Pantograph and Catenary in High-speed Electrified Railway

高速电气化铁路弓网系统中的电弧已经成为制约我国高速铁路发展的技术瓶颈。笔者论述了电弧对接触导线、受电弓滑板、通讯信号、无线电信号和供电质量等的危害,从电弧产生的机理和特征、电弧模型、电弧能量、电弧侵蚀和载流摩擦磨损方面综述了相关电弧问题的研究现状,为深入开展弓网电弧现象、机理及抑制措施的研究打下了基础。

The arc phenomenon between pantograph and catenary is a technical bottleneck in the development of high-speed electrified railway in China. The harm of arc to contact wire, pantograph, communication signal, radio signal and power supply quality is analyzed in this paper. The current researches on mechanism and characteristics of the arc, the arc model, arc energy, arc erosion, and frictional wear due to electrical current are discussed to supply a foundation for further researches of arc phenomenon between pantograph and catenary, arcing mechanism, and arc inhibition methods.
