摘要
在电力系统中,配电变压器作为能源转换和分配的核心设备,其综合能效的提升对降低能源成本、减少环境污染、推动可持续发展具有重要意义。在设备选型过程中,除了技术参数,变压器的经济评价也应作为选型的重要依据。文章基于《配电变压器能效技术经济评价导则》(DL/T 985—2022),以某污水泵站的变压器改造项目为研究对象,通过计算与分析,得出不同容量、不同能效等级变压器的经济评价结论,以期为设计人员开展变压器选型工作参考依据。
In the power system,the distribution transformer is the core equipment for energy conversion and distribution.Enhancing its comprehensive energy efficiency is of great significance to reduce energy costs,reduce environmental pollution and promote sustainable development.During equipment selection,in addition to technical parameters,the economic evaluation of the transformer should also be used as an important basis for selection.Based on Guideline for the Technical and Economic Evaluation of Distribution Transformers'Energy Efficiency(DL/T 985-2022),this paper takes the transformer renovation project at a sewage pump station as the research object,through calculation and analysis,the economic evaluation conclusions of transformers with different capacities and different energy efficiency levels are obtained,in order to provide reference for designers to carry out transformer selection work.
