摘　　要：变压器节能是电气节能中的一个重要分支。本文结合有色金属加工行业的特点,介绍变压器产生的损耗及计算方法,计算SCB11、SCB12、SCB13变压器的有功功率损耗、无功功率损耗和有功电能损耗,并以SCB11为基准,计算选择SCB12、SCB13变压器多付出的投资的资金回收周期,以及以SCB9为例,计算将高能耗变压器置换为SCB11、SCB12、SCB13所节省的电能。计算结果表明,在高电价区域,新建工程项目应当选择最新型的节能变压器;在低电价区域,有条件的情况下尽可能选择最新型的节能变压器;高能耗变压器置换可以节约大量电能,且变压器容量越大,节省的电量就越多。建议企业结合发展规划,借助技术改造升级或厂址搬迁的机会将高能耗变压器更换为最新型的节能变压器。Combining with the features of non-ferrous metal processing industry,this paper discussed the transformer loss and its calculation method.The total active power loss,reactive power loss and active energy loss of SCB11,SCB12 and SCB13 transformers were calculated.Taking SCB11 as baseline,this paper also calculated the payback period of the excess cost of selecting SCB12 and SCB13 transformers.Taking SCB9 as an example,the power saved through replacing high energy consumption transformer to SCB11,SCB12 and SCB13 were also calculated.The calculation results showed that the latest energy-saving transformer should be selected for new construction projects in high electricity price areas;in low electricity price areas,the latest energy-saving transformers should be selected as much as possible if available.Replacing high energy consumption transformer can save a lot of electric energy every year,and the larger the transformer capacity,the more electric energy can be saved.It was suggested that enterprises should replace the high energy consumption transformer with the latest energy-saving transformer with the opportunity of technical transformation and upgrading or site relocation in combination with enterprise development planning.
