摘　　要：变压器的能效等级选择是电气节能设计的重要组成部分,国家及地方标准对此亦有重点强调。从变压器整个使用寿命期间的运行成本角度考虑,分析不同负载率及能效等级下变压器的运行成本,并结合实际案例予以说明,提供一个在最低成本下合理选择变压器能效等级的分析方法。The selection of energy efficiency levels for transformers is an important part of the electrical energy‑saving design and is also highlighted in national and local standards.In this paper,from the perspective of operating costs throughout the service life of transformers,the operating costs of transformers at different load factors and energy efficiency levels are analyzed and are also explained in combination with practical cases to provide an analysis method for selecting energy efficiency levels for transformers reasonably at the lowest cost.
