摘要
随着变压器能效新标准GB 20052-2020《电力变压器能效限定值及能效等级》的发布,国家对变压器能效提出了更高的要求,在新型电力系统和双碳背景下,能效变压器等新型节能设备将广泛地应用于电网建设。本文通过对新能效变压器与传统变压器的材料组成、采购成本、运行成本、碳排放对比分析,确定新能效变压器在新型电力系统中的优势,最后根据能效变压器的特点(价值属性和供应风险),将能效变压器划分到卡拉杰克模型中去,得出对应的采购建议,为电网公司对新能效变压器的采购提供参考。
With the release of the new standard for transformer energy efficiency GB 20052-2020 Power Transformer Energy Efficiency Limits and Energy Efficiency Grades,the country has put forward higher requirements for transformer energy efficiency.Under the background of new power system and double carbon,new energy-saving equipment such as energy efficiency transformers will be widely used in power grid construction.Through the comparative analysis of the material composition,procurement cost,operation cost and carbon emission between the new energy efficiency transformer and the traditional transformer,this paper determines the advantages of the new energy efficiency transformer in the new power system.Finally,according to the characteristics of the energy efficiency transformer(value attribute and supply risk),the energy efficiency transformer is divided into the karajake model,and the corresponding procurement suggestions are obtained,which provides a reference for the power grid company to purchase the new energy efficiency transformer.
