摘　　要：确保输变电线路的连续运行极为重要,对于超高压直流线路更是如此。所以,加拿大马尼托巴(Manitoba)水电公司(以下简称MH公司)在确认其昂代拉迪森至多塞(HendayRadisson-Dorsey)500kV高压直流线路上的间隔棒减振器装置出现故障时,在线路带电情况下,立即对这些装置进行检修,并加装了一些新的减振器。文章介绍其采用的更换技术、实施过程中遇到的问题及解决方法。Maintaining continuous operation ofa transmission line is very important. The concern is even more critical when discussing an extra-high-voltage （EHV） line. That is why Manitoba Hydro（MH） changed out spacer-damper units quickly when ascertaining them failing on its Henday Radisson-Dorsey 500-kV HVDC line. While the line remaiued energized, MH refurbished these units; and installed additional dampers. The technology applied, problems eucountered and solution methods are described in this paper.
