摘　　要：特高压变压器由主体变压器与调压补偿变压器组成,与传统变压器相比,其差动保护需增加调压补偿变差动保护。文章首先分析了特高压变压器调压方式,阐述了调压补偿变的工作原理,通过介绍淮南站调压补偿变的差动保护配置,分析了不同调压档位下的保护极性问题,为后续特高压变电站的运行维护提供参考。The UHV transformer is composed of two parts： the main transformer, the regulation and compensating transformer. Compared with traditional transformer, there are individual differential protections for the regulation and compensating transformer. This paper analyzes the voltage regulation model of UHV transformer, and expounds the operating principle of the regulation and compensating transformer. Through introducing the differential protection configuration of Huainan station, the protection polarity problem of different tap positions is analyzed, which can provide some references for the subsequent operating and maintenance of UHV station.
