昆明特高压试验研究基地特高压直流试验线段设计

UHV DC Test Section Design of Kunming UHV Test & Research Base

为保证云南至广东±800 kV特高压直流工程设计、建设的顺利进行和以后的安全运行,在昆明高海拔地区建设了特高压试验研究基地。试验基地的试验线段分为±800 kV直流和1000 kV交流单回路试验线段,其中±800 kV直流单回路试验线段已成功带电投运。根据试验要求,在塔型设计、杆塔结构、可变金具串型式等方面做了探索性的研究和设计工作。

To ensure the engineering design, construction and future safe operation of ±800 kV DC project from Yunan to Guangdong, a UHV test ＆ research base was constructed in Kunming high-elevation area above sea level. The base test section consists of 1 single-circuit ± 800 kV DC section and 1 single-circuit 1 1300 kV AC section. The ±800 kV DC section has been successfully put into operation. To meet the test requirements, exploratory study and design have been conducted on tower type design, tower structure and variable fittings.
