轨道交通刚性悬挂接触网关键技术分析

Analysis of Key Technologies of Rigid Catenary for Rail Transit

在城市轨道交通工程建设中,不断提升的设计时速对刚性接触网提出了更高的要求。结合工程实际,对刚性悬挂接触网的安装形式、锚段长度及关节形式、刚柔过渡等3项关键工程技术进行了分析对比,探讨了既有装配形式的问题,给出了刚柔过渡改进的建议。

In the construction of urban rail transit projects,the increasing design speed asks higher requirements for rigid catenary.Combined with the actual engineering practice,three key engineering technologies,namely the installation form,the length and form of anchor section joints and rigid-flexible transition of rigid catenary,are analyzed and compared.The problems of the existing assembly form are discussed and suggestions for the improvement of rigid-flexible transition are given.
