摘    要:随着列车运行速度的提高,弓网离线现象愈来愈严重,弓网电弧频繁发生,弓网电弧烧蚀受电弓滑板和接触网导线,其烧蚀程度与弓网电弧能节的大小密切相关.利用弓网电弧模拟试验系统研究不同负载功率因数、牵引电流时弓网电弧的电压电流,分析弓网电弧的平均燃弧时间与牵引电流和负载功率因数的关系、弓网电弧能量与负载功率因数的关系.研究结果表...

关 键 词:功率因数  弓网电弧  电弧能量  燃弧时间

Abstract:Due to the increasing speed of the locomotive,the pantograph-catenary disconnection was getting worse,and the pantograph arc occured frequently.The pantograph arc etched the pantograph slider and contact wire,and the etching level was influenced by arcing energy.In this paper,the arc voltage and current of different traction current and power factor was measured by pantograph-catenary arcing test system.The relationship between average arcing duration and traction current,power factor of load was analyzed,a...
Keywords:power factor  pantograph arcing  arc energy  arcing duration
