架空刚性接触悬挂的特点及其维修

Characters of Rigid Suspension of Overhead Contact System and its Maintenance

广州地铁二号线是国内首条采用架空刚性接触悬挂技术的接触网,国外地铁已大量采用架空刚性接触悬挂,效果很好。架空刚性接触悬挂具有整体结构简单、锚段关节和线岔安装调试方便、弓网间的压力和接触线磨耗均匀、悬挂两端无需设置下锚张力补偿装置、没有断线之忧、施工安装和维修精度要求高等特点,另外架空刚性接触悬挂能很好地满足低净空隧道要求,适用于地下铁道。

No.2 Line of Guangzhou Metro is the first line adopting technology for rigid suspension of overhead contact system in China. The technology for rigid suspension of overhead contact system has been comprehensively applying in Metro of foreign countries and showing well results. Rigid suspension of overhead contact system, with advantages i.e. simple in complete structure, easy in installation and commissioning of overlap and overhead crossover, even pressure between pantograph & OCS, even wear of contact wires, tensioning device-free at both ends of anchoring, worry-free for wire broken, higher accuracy for installation and maintenance, and with another advantage of satisfying the requirement for lower clearance of tunnel, is more suitable to the Metro.
