摘　　要：本文介绍了大容量单相发电机主变压器的常用结构型式,以一台单相315MV·A/500kV发电机主变压器技术参数为例,对三种常用结构型式从变压器的铁心尺寸、运输方案、技术经济性三方面进行了对比分析,并通过变压器漏磁场仿真分析软件和波过程计算软件对三种结构的漏磁分布和绝缘特性进行了仿真计算。通过对不同结构型式的经济性和安全可靠性进行分析,总结了三种常用结构型式的优缺点及结构选型和设计时需重点考虑的因素。This paper introduces the common structural types of the large capacity single phase generator step-up transformer.Taking a single-phase 315MV·A/500kV generator step-up transformer as an example,the three commonly used structural types are compared and analyzed from three aspects of transformer core size,transportation scheme and technical economic.The magnetic flux leakage distribution and insulation characteristics of the three structures are simulated by the magnetic simulation analysis software and wave process calculation software.Based on the analysis of economy and safety reliability of different structural types,the advantages and disadvantages of three commonly used structural types and the key factors to be considered in structural selection and design are summarized.
