新疆地区±800kV特高压直流线路导线选型研究

Study on Conductor Type Selection of±800kV UHV DC Lines in Xinjiang

对导线选型进行研究是特高压直流线路的重要工作之一,导线在输电线路中作为电能输送的主要载体,是最重要的组成部分,在保证输送电能安全可靠的同时,必须满足环境保护相关要求与经济合理。针对不同型号的导线方案,从电气特性、机械性能等方面进行比较,并基于导线、杆塔与基础等工程量对线路造价进行比较,从而确定合理的特高压直流线路导线方案。

Studying conductor type selection is an important task of ultra-high voltage direct current lines.Conductors,as the main carrier of electricity transmission,are the most important component of transmission lines.While ensuring safety and reliability of electricity transmission,conductor wires must meet the requirements of environmental protection and economic rationality.This article compares electrical characteristics,mechanical properties,and other aspects of different types of conductor wires,and compares the cost of transmission line based on the quantities of wires,towers,and foundations,in order to determine a reasonable wire scheme for ultra-high voltage DC lines.
