弓网系统动态及受流性能测试技术研究及应用

在列车高速运行条件下,保证弓网系统具有良好的受流质量是高速电气化铁路的关键技术之一,即保持受电弓/接触网接触副间有稳定的电能传输。但如何评价其受流性能,即根据什么检测内容、测试方法和评价准则来评估弓网动态及受流性能的优劣,是弓网关系研究需要解决的问题。围绕弓网系统动态相互作用及受流性能的检测,着重介绍接触压力、加速度、导线动态高度及燃弧等关键参数相关检测技术的现状、不足及发展趋势;同时探讨了上述关键参数之外的其他性能参数的测试技术,并对相关的研究动态进行了论述。

Investigation on and Application of Measurement Technology of Dynamic Performance and Current Collection Quality of Pantograph-catenary System

With respect to the high speed electrified railway,one of key technologies is to ensure good current collection quality of pantograph and catenary system and keep a steady contact between pantograph and catenary during high-speed train operation.However,the evaluation of the current collection quality,including the use of certain measurement items,methods and evaluation criteria is a key problem to be solved in the research of pantograph catenary relationship.In this paper,the present situation,deficiency and development trends of the measurement technology for the key parameters of pantograph and catenary system,including contact forces,accelerations,dynamic height of contact wire and break arcs were discussed.In addition these parameters,other dynamic parameters of the measurement methods were also introduced and the related basic research progress was described.
