变压器节能设计的探讨与分析

Discussion and Analysis on Energy Conservation for Transformers

探讨国家规范变更过程中变压器的选用变化,对比不同等效等级变压器的损耗。综合浙江省工程建设标准、机械行业标准和产品型号管理办法,总结浙江省各级绿色建筑的变压器型号的选择方法。在介绍变压器经济运行参照标准的基础上提出了对参照标准合理选择的理解,计算和提出电工钢带变压器能效等级1级、2级、3级的经济运行区和最佳经济运行区。

The selection and change of transformers in the process of national code change were discussed in depth,and the differences of transformer losses of different equivalent grades were compared.Based on the engineering construction standards,machinery industry standards and product model management measures of Zhejiang Province,the selection methods of transformer models for green buildings at all levels in Zhejiang Province were summarized.On the basis of introducing the reference standard of transformer economic operation,this paper puts forward the understanding of the reasonable selection of the reference standard,calculates and puts forward the economic operation area and the best economic operation area of electrical steel strip transformer with energy efficiency grades of 1,2 and 3.
