摘　　要：为合理选择220kV自耦变压器的20kV侧容量,依据国家及行业规程、标准,对自耦变压器的特点和低压侧容量进行了分析,综合具体负荷需求、无功补偿、设备造价等因素,建议在标准化设计中,220kV自耦变压器(220/110/20kV)的20kV侧容量宜统一按变压器额定容量的50%来选择。In order to logically select 20 kV side capacities of 220 kV autotransformers, analysis was made on characteristics and low-voltage side capacities of autotransformers according to regulations and standards of the nation and industry. Specific load demand, reactive power compensation, equipment costs and other factors integrated, it is suggested that in the standardized design 20 kV side capacities of 220 kV autotransformers （220/110/20 kV） should be uniformly selected according to fifty percent of transformers＇ rated capacities.
