特殊区段牵引供电接触网支持装置的安装及调整

摘要

Combined with the traction power overhead contact line installation on the highway/railway dual bridge in Wuhan City,factors in special sections like the small limit and low clearance of the overhead contact line are analyzed,solutions are put forward to ensure the satisfactory installation of support device and adjustment.Practical engineering proves that changes of the supporting mode in special sections and proper adjustment of the technical parameters in the installation of overhead contact line support device in special section are feasible.%结合武汉天兴洲公铁两用桥牵引供电接触网安装工程,对小限界、低净空特殊区段接触网支持装置的安装及调整的限制因素进行分析,并提出解决方法,以确保支持装置安装及调整达到要求.实践证明,小限界、低净空特殊区段接触网支持装置采用改变支持形式、适当调整技术参数的方法切实可行.
