| Abstract: | The HY-type converter transformer in Yunnan-Guangdong DC project is the first one in the world, which has a very complex structure and requires high technic level of constructure and installation. An indirect outlet conformation is adopted by the transformer, and it is favorable for heavy-cargo transportation, but faces much more difficulty in the installation. This paper introduces the experience of HY-type converter transformer installation and related key technics, including wire connection, in-sulation binding, bushing davit-mounting, vacuum dry, oil process, traction location and hand-over test. |
