摘 要 介绍了刚性悬挂接触网的基本结构和在施工中的工程测量、汇流排安装、接触线镶入的基本方法和要求,以及工程中的注意事项。

刚性接触网是一种工程造价低、安全可靠、无或少维修的供电方式,在国外地铁领域中的应用已较为成熟。其中,日本214 km 、韩国148 km 、德国15 km 、瑞士18 km 的地铁线中采用了这种形式。而这种技术在我国城市轨道交通领域中的应用才刚刚起步,目前只是在广州地铁1 号线坑口—花地湾间有一段全长108 m 试验段,广州地铁2 号线也在试运营中。目前准备采用这种方式的有上海的M8 线、南京地铁、沈阳地铁等线路。刚性悬挂接触网以其明显的优势在城市地铁建设中越来越凸现出广阔的应用前景。

接触网刚性悬挂是一种适用于轨道交通在隧道中传输电能的新型接触网悬挂方式。在我国电气化铁路接触网施工中是首次使用,刚性悬挂方式与柔性悬挂方式相比,其结构简单、安装方便、维护简便、节省空间,被称之为免维护接触网,降低建设成本和减少了未来运营维护的工作量。主要研究在接触网施工中,刚性悬挂的技术标准和施工方法,为今后工程提供科学依据,优化设计,保证具体措施的合理性和有效性。

Abstract

Describes the rigid catenary suspension the basic structure and in the construction of the engineering survey, bus installation, insert into the contact line of the basic methods and requirements, and engineering considerations. Rigid catenary is a lower project cost, safe, reliable, maintenance-free power supply or less, in the application of foreign metro area has been more mature. Among them, Japan 214 km, South Korea 148 km, Germany 15 km, Switzerland 18 km of subway lines using this form. And this …… 此处隐藏：13616字，全部文档内容请下载后查看。喜欢就下载吧 ……
