摘要
随着动车组速度的提升,弓网离线成为一种高速动车组运行时普遍存在且不可避免的现象。弓网离线导致的网压中断问题会影响动车组牵引系统的可靠运行,文章基于某型高速动车组牵引系统,介绍了牵引系统的构成和现行网压中断的保护方案,提出一种针对短暂弓网离线的适应性提升方案,降低短暂弓网离线对牵引系统的影响,提高列车运行效率。地面试验结果和线路运营考核数据均表明,文章提出的弓网离线适应性提升方案效果明显。
With the increase of EMU speed,pantograph catenary offline has become a common and inevitable phenomenon in high-speed EMU operation.The network voltage interruption caused by pantograph catenary offline will affect the reliable operation of EMU traction system.Based on the traction system of a high-speed EMU,the composition of the traction system and the current protection scheme of the network voltage interruption were introduced,and an adaptive lifting scheme for the short-term pantograph catenary offline was proposed,so as to reduce the impact of the short-term pantograph catenary offline on the traction system and improve the train operation efficiency.The ground test results and line operation evaluation data showed that the proposed pantograph catenary offline adaptability improvement scheme was effective.
