摘要:
架空刚性接触网是城市轨道交通常用的接触网方案，其跨距选择对弓网系统受流质量影响较大，因而选择与列车运行速度相匹配的接触网跨距相当重要。考虑弓网系统受流质量影响因素，从刚性接触网波动传播速度及接触网系统整体不平顺度等方面，分析了接触网跨距与列车运行速度的匹配关系，从而得出与列车运行速度匹配的刚性接触网跨距布置原则的建议方案。

Overhead rigid catenary is a common catenary scheme in urban rail transit. Its span selection has a great influence on the current collection quality of pantograp |catenary system. Therefore, it is very important to select a suitable span of overhead catenary that matches the train operating speed. Considering the influencing factors of current collecting quality of pantograph\|catenary system, the matching relationship between span of catenary and train operating speed is analyzed from the aspects of wave propagation speed of rigid catenary and overall irregularity of catenary system, thus the principle and suggestion scheme of rigid catenary span arrangement matching with train operating speed are obtained.
