摘要

尽管定期进行离线电气测试和在线油中气分析，但在12个月内，有3台高压直流换流变压器发生故障。对可能的故障原因进行审查，并对可能延长类似变压器寿命的维护、监控和系统操作进行更改。

Analysis of winding failures in HVDC converter transformers

In spite of periodic off-line electrical tests and on-line gas-in-oil analysis, three HVDC converter transformers have failed within a 12-month period. The possible causes of failure are reviewed together with changes in maintenance, monitoring and system operation that might prolong the life of similar transformers.
