接触网的动态变化特性对改进施工的几点启示

Revelations of Contact Net's Dynamic Characteristics in Improving Construction

接触网受气温、机车受电弓高速滑动和牵引电流剧烈波动等众多因素的影响,其状态时刻处在复杂的动态变化之中。这种动态变化直接影响接触网的质量稳定和运行安全。因此,在施工时不仅要确保接触网的静态参数满足标准要求,而且要保证这些参数的动态变化范围不超限。在分析接触网动态变化特性的基础上,提出了改进施工的几点启示,对提高接触网施工质量具有一定参考价值。

Influenced by such factors as the temperature,train s pantograph high-speed sliding and the violent fluctuation of the traction current,the contact net is in a complicated dynamic state.This dynamic change will affect the contact net s quality stability and secure operation.Therefore,in the construction,not only the static parameters of the contact net should meet the standard requirements,but these parameters mustn t exceed the range of the dynamic change.Based on the analysis on the dynamic characteristic...
