【摘要】：输电线路作为接连变电站与电网的桥梁，也是电力传输的唯一通道，在土地日渐紧张的今天，如何在土地资源极有限的城区中合理的设计输电线路成为了当前电力工程的关键环节。特别是中心区域，受到周边的企业、居民区、商业区和城市道路地下各种各样的管线限制，输电线路在三维空间中受到了非常大的制约。而且输电线路工程往往会遇到选线困难、环评工作难、规划调整难、征地拆迁难、电站电缆路径通道落实难、设计反复等原因，使得很多线路工程无法按期竣工和向目标发展区域提供服务，从而影响周边区域的经济发展和人民生活。本论文通过对目前城市电缆终端的占地面积大、费用过高、检修维护困难等状况进行分析，论述其存在问题的原因。针对这些问题提出一种可以解决上述问题的新型电缆终端塔。并将整塔分割为塔头间隙圆、电缆终端平台以及杆塔荷载，3个部分分别进行设计，在通过设计输入条件的选取、塔头尺寸、电缆及电缆附件的选型、电缆终端平台等内容的分析计算，最终完成整塔的设计并对使用情况进行总结。
[Abstract]:As a bridge between substations and power grids, transmission lines are also the only channel for power transmission. Today, the land is increasingly tight.How to reasonably design transmission lines in urban areas with limited land resources has become the key link of current power engineering.Especially the central area is restricted by various pipelines in the surrounding enterprises residential areas commercial districts and urban roads. Transmission lines are restricted in three-dimensional space.Moreover, transmission line projects often encounter difficulties in line selection, environmental impact assessment, planning and adjustment, land acquisition and removal, implementation of power station cable paths, repeated design, and so on.As a result, many railway projects can not be completed on schedule and provide services to the target development areas, thus affecting the economic development and people's lives in the surrounding areas.Based on the analysis of the status of large area, high cost and difficult maintenance of urban cable terminals at present, this paper discusses the causes of the problems.To solve these problems, a new type of cable terminal tower is proposed to solve the above problems.The whole tower is divided into three parts: the gap circle of the tower head, the terminal platform of the cable and the load of the tower tower. The input conditions, the size of the tower head, the selection of cable and cable accessories are selected through the design.Analysis and calculation of cable terminal platform, the final completion of the tower design and use of summary.
