摘　　要：溪洛渡水电站500kV主变压器采用三相组合油浸式水冷升压变压器，本文从安装质量和工期进展方面，并结合现场安装条件对主变安装方法“单相本体安装法”进行分析优化并总结提出“三相整体安装法”，有效缩短安装工期、降低安装质量影响因素。电站18台500kV变压器安装质量优良，顺利通过交接试验并投入运行。此方法为国内其他地下厂房电站500kV三相组合式变压器的安装提供经验。The 500kV transformer is three phase-combined off-immersed water-cooled transformer in Xiluodu Hydropower Plant. Considering the installation quality and the installation period, this paper analyses and optimizes the ＂single-phase installation method＂ ,concludesthe ＂three-phase integral installation method＂ that combined with the site installation conditions, this method effectively shorten the installation period and reduce the installation quality influence factors. All of the 18 500kV transformers＇ installation quality achieved excellent standards,and successfully passed the acceptance test and put into operation. ＂three-phase integral installation method＂ provides installation experience for other 500kV three-phase combined transformer underground power station.
