摘　　要：SFC系统作为抽水蓄能电站机组的启动装置,输入/输出变压器作为SFC系统的核心设备,输入变压器使来自系统的电压与整流器的工作电压相适配,输出变压器使逆变桥的输出电压与机组电压相适配。抽水蓄能的电站单台机组容量大,所需变压器对应容量也非常大,且系统运行工况特殊,可靠性要求高,该类变压器设计、制造、运输、安装等复杂,为此主要探讨了该类变压器的基本原理,产品设计特点,以期对该类变压器的设计有一定指导意义。The SFC system serves as the starting device for pumped power storage units,with input/output transformers as the core equipment of the SFC system.The input transformer matches the voltage from the system with working voltage of the rectifier,and the output transformer matches the output voltage of the inverter bridge with unit voltage.The large capacity of a single unit in a pumped power storage station determines the large capacity demand for its transformer.Moreover,the system operating conditions are special,and the reliability requirements are high.The design,manufacturing,transportation,installation,and other aspects of this type of transformer are complex.This paper mainly discusses the basic principles and product design characteristics of this type of transformer,which may provide useful information for the design of this type of transformer.
