刚性接触网环境下的弓网性能试验

针对广州地铁3号线车速为120 km/h刚性接触网环境,运用检测装置对3号线弓网系统进行试验,检测刚性接触网环境下的弓网接触力、弓头及框架的振动、滑板的温升等情况.分析了受电弓的动态性能,以及受电弓在刚性接触网下的振动、特别是列车高速运行时的振动情况,找出受电弓频繁故障的原因,为优化架空刚性弓网系统提供帮助.

Test of Pantograph and Contact System in Stiff Contact Environment

Referring to the stiff contact environment at the speed of 120 km/h for Guanzhou Metro Line 3,this paper is specialized in some situation analyses.With a test of the pantograph & contact system of Line 3 by inspection equipment, the system's contact force is checked,the head and frame vibration,the temperature for contact strip arc discussed in the paper.By analyzing pantograph & contact system's dynamic performance,especially the high-speed vibration under stiff contact system environment,this paper hopes ...
