1 000 kV特高压交流试验基地试验线段设计概述

1 000 kV 架空输电线路在我国为新的电压等级输电线路, 属特高压输电技术。1 000 kV 晋东南-南阳-荆门试验示范工程的设计过程中, 对关键技术、设计专题进行了研究, 同时参考了国外特高压架空送电线路的已有经验, 但研究结果的工程适用性仍有待试验检验。为保证交流特高压试验示范工程设计、建设的顺利进行和以后的安全运行, 在武汉建成了特高压交流试验基地, 并且单回试验线段成功带电试运行。试验基地的线路部分分为单、双回路试验线段, 根据试验要求, 在塔型设计、杆塔结构、金具串型式等方面做了探索性的工作。

Introduction to Testing Section Design of 1000 kV UHV AC Testing Site

1 000 kV UHV overhead transmission line belongs to a new voltage class in China.In the design of Jindongnan-Nanyang-Jingmen demonstration project,studies of key technologies and designs,as well as available foreign practices,were conducted.However,its applicability has not yet been tested.To ensure smooth construction of the demonstration project and safe future operation,UHV AC testing site was established in Wuhan,and single circuit testing section trial operation was successful.The testing lines consist of single and double circuit sections.To meet testing requirements,exploratory works in tower type selection,pole and tower structure,fitting type,etc.,are conducted.
