摘要
分析了地铁提速后隧道内刚性接触网运行中存在的拉弧、磨耗严重等问题。提出对现有垂直悬挂方式进行技术更新,采用已有成熟运行经验的悬臂支撑方式。针对地铁隧道内灾害,如地震、火灾、渗漏水或结冰等对刚性接触网的影响,研究采用防开裂型化学锚栓、扣紧螺母及防水融冰等技术措施,并采用隧道内接触网视频监控装置,对各接触网关键点的工作状态及受电弓运行状态进行实时监控,以指导隧道内接触网设备的维护、抢修及救援疏散等工作。
Abstraet With an analysis of the arc discharge and serious wear of overhead rigid suspension catenary （ORSC） in met- ro tunnel, some technical improvements are proposed, in- cluding the adoption of mature cantilever mode in China railway. According to the effect of earthquake, fire disas- ter, percolating water or freeze to ORSC in metro tunnel, adoption of the anti-cracking chemical anchor, binding nut and waterproof, melting ice resistant measures are re- searched, meanwhile, a video surveillance device of ORSC in metro tunnel is recommended as an assistant management means.
