电气设计中变压器绿色选型问题的探讨

Discussion on Green Type Selection of Transformer in Electrical Design

近年来,国家大力倡导绿色制造、可持续发展的理念,出台一系列政策及标准,如GB20052—2020《电力变压器能效限定值及能效等级》、《电力变压器能效提升计划(2021—2023)》等,以及即将完成编制的上海市团体标准《民用建筑电气绿色设计与应用规范》,旨在推广及应用高效节能技术、绿色制造的新一代绿色电气产品。变压器等电气设备绿色选型已得到电气设计人员的广泛关注。重点探讨了电气设计中变压器绿色选型相关问题,以期为电气设计人员提供参考。

In recent years, China has advocated the concept of green manufacturing and sustainable development, and issued a series of policies and standards, such as GB 20052-2020 Minimum allowable values of energy efficiency and the energy efficiency grades for power transformers,Power Transformers Energy Efficiency Improvement Plan(2021-2023),Shanghai group standard Code for the application of civil buildings electrical green design which aims to promote and apply a new generation of green electrical products made with high efficiency and energy saving technology.The selection of green electrical equipment such as transformers has been widely concerned by electrical designers.This paper focuses on the green selection of transformers in electrical design, which can provide reference for electrical designers.
