摘要:
针对受电弓弓角磨损情况,结合城市轨道交通受电弓和道岔结构形式,对场段内道岔定位原则、道岔定位方案设计要点进行分析。由分析结果可以看出,传统岔前3 m定位方案具有局限性,而岔心定位方案不受限制。建议场段内接触网道岔定位优先采用岔心定位方案。
Abstracts:
According to the abrasion of pantograph corner, and combined with the structure of pantograph and switch in urban mass transit, the principle and the key design points of the switch positioning are analyzed. The result shows that the traditional front 3 m positioning scheme has its limitation, while the frog positioning scheme is unrestricted. Therefore, it is suggested that the OCS switch positioning in urban mass transit depot should adopt the frog position scheme.
