摘要：随着科技的发展，人们对电的需求日益增长，由于能源资源与生产力发展的逆向分布，能源供需矛盾突出，原有的煤炭长距离运输、就地发电、自求平衡能源供应方式也难以为继。不但运力瓶颈问题难以解决，资源浪费、环境污染等问题也十分突出。输电塔在我们的生活中随处可见，特高压输电塔的应用也愈发广泛。特高压电网具有输电容量大、送电距离长、线路损耗低、工程投资省、土地利用效率高和联网能力强等优点。

本文主要完成的工作包括以下几点：

(1)针对特高压输电塔的组成和结构进行了分析，了解了输电塔国内外历史发展过程，为输电塔的建模提供专业领域知识。

(2)构建了一套基于Creator的悬垂式鼓型输电塔三维模型，对其进行细化建模，介绍了输电塔的整体框架和组成。

(3)借助Creator软件对特高压输电塔建模，能够对输电塔体系架构的深入认识，同时还能够为特高压输电塔安全施工提供有益的参考建议。

Title      Research on 3D Modeling of Typical UHV  Transmission Tower System            

Abstract：With the development of science and technology, people's growing demand for electricity, due to the reverse distribution of energy resources and productivity development, energy supply and demand contradictions, the original long-distance transport of coal, local power generation, self-balancing energy supply is difficult Following. Not only the bottleneck problem is difficult to solve, waste of resources, environmental pollution and other issues are also very prominent. Transmission tower in our lives can be seen everywhere, UHV transmission tower applications are increasingly widespread. UHV power grid has the advantages of large transmission capacity, long transmission distance, low line loss, high investment in engineering, high land use efficiency and strong networking ability.

The main work of this paper includes the following:

(1) The composition and structure of the UHV transmission tower are analyzed, and the historical development process of the transmission tower at home and abroad is understood, and the knowledge of the transmission tower is provided.

(2) A three-dimensional model of cantilevered drum-type transmission tower based on Creator is constructed, and the whole framework and composition of the transmission tower are introduced.

(3) With the Creator software to model the UHV transmission tower, it can realize the deep understanding of the transmission tower system architecture, and also provide useful reference for the safe construction of the UHV transmission tower.
