摘要:

南方电网所有直流输电系统中,±800 kV云广特高压直流首次使用了真空有载分接开关,本文首先介绍真空有载分接开关的工作过程,然后总结分析了云广±800 kV直流输电工程中换流变分接开关125℃闭锁调整的原因,对其存在的风险进行深入剖析,最后提出有效的处理措施,降低云广特高压直流输电系统闭锁的风险。

Yunnan-Guangdong ±800 kV DC transmission project is the first project which uses vacuum on-load tap- changer in all DC transmission projects of CSG. The paper introduces the operation of vacuum on-load tap-changer firstly, then summarizes and analyzes the cause of converter transformer OLTC 125°C blocking in Yunnan-Guangdong ±800 kV DC transmission project, and analyzes its risk thoroughly, at last, some effective measures which can depress the risk of blocking both pole in Yunnan-Guangdong ±800 kV DC transmission project are given.
