摘　　要：厄瓜多尔Coca Codo Sinclair(简称CCS水电站)500kV主变压器由于运输限制采用单相式,电压等级高,布置难度大,加之机电设计采用美国和IEC标准,并按国际惯例实行第三方咨询审查制度,其设计中存在许多特殊技术问题,仅针对主变布置、高压套管引出方式及防火防爆等特殊问题进行总结介绍,供相关人士参考。Beacause of the transportation restriction, Ecuador Coca Codo Sinclair hydroelectric power plant （CCS for short） adopts the single phase 500kV main transformer. It is the high voltage level, and it is difficult to lay out. American and IEC stadard is used for mechanical and electrical design, and the third-part international consulting is carried out. So there are lots of special technical problems. This paper summarizes and introduces special problems, such as transformer layout, high voltage bushing leading mode, fire and explosion proof, and so on. Some interrelated people can refer to it.
