摘　　要：介绍有载分接开关的工作原理及其在云广±800kV直流工程的应用情况。在云广直流工程中,为了减少电弧对绝缘油的影响,采用了真空有载分接开关(VACUTAP),并在有载分接开关加装了在线滤油单元,以优化有载分接开关的运行环境和延长电力变压器的使用寿命。The working principle of vacuum OLTC and its application to Yunnan-Guangdong ±800 kV DC project are introduced.In order to reduce the effect of arc on the insulating oil,VACUTAP,a kind of vacuum OLTC,is adopted in the DC project,and an online oil filter unit is added to the vacuum OLTC to optimize its operation environment and to extend the service life of power transformers.
