弓网接触压力超限与几何参数缺陷相关性分析

Analysis of Correlation between Out-of-limit Contact Pressure of Pantograph-catenary and Geometric Parameter Defects

高速弓网综合检测装置(1C)是检测发现高速铁路接触网缺陷并指导维修的重要手段,但是在检测发现的压力缺陷复核和处理上,现场尚无较好的处理方法。针对该问题,对检测发现弓网接触压力超限问题与几何参数缺陷相关性进行分析,显示二者之间的相关性较大,压力缺陷的复核和处理应重点关注一跨内接触线高差问题,为现场复核和处理压力超限问题提供参考。

The comprehensive inspection device for pantograph-catenary of high-speed railway(1C)is an important means for inspection and finding of defects as well as for guidance on maintenance of high-speed railways.However,there is still no better way to review and handle the pressure defects found in the inspection.With regard to this problem,the analysis of correlation between the over-limit pressure of pantograph-catenary and geometric parameter defects is made,and the results show that and the correlation between the two is significant.The emphasis shall be given to the issue of height difference of contact wire within one span for review and handling of the pressure defects.This is able to provide reference for review and handling of out-of-limit pressure at site.
