摘　　要：当前国内大面积推广使用节能型变压器,基于此,对国内外的变压器的节能技术和方法进行了详细的综述,包括优化变压器材料、变压器结构改造、变压器全寿命周期管理、加强变压器状态检修、变压器容量的合理选择、变压器的经济运行和采用无功补偿装置等,并给出了变压器运行方式经济切换法进行节能计算的实例,与变压器传统运行方式耗能进行了对比,证明了当前传统运行方式的节能潜力,同时给出了变压器无功补偿节能效益计算实例,表明从无功补偿的角度进行节能的必要性。探讨了当前变压器节能方法研究的薄弱环节,并对未来研究方向做出展望。分析得出专线用户企业尤其是高耗能企业应尽快推广使用新型节能变压器,充分挖掘节能潜力,提高生产效益。The type of energy conservation transformers has been popularizing in large scale at home and abroad,on the basis, a detailed review and analysis was made on domestic and abroad energy conservation techniques and methodsof distribution transformer, including the transformer materials optimization, structure modification, life-cycle management,condition-based maintenance, rational capacity selection, economic operation and reactive power compensation, etc. moreover,the transformer operation mode economic switching method was shown as an example of energy conservation calculation, whichwas compared with the traditional operation mode in aspect of energy consumption, and it’s proved that there was a strongenergy conservation potential ability in current conventional operation modes. Meanwhile, an example of transformer reactivepower compensation energy conservation benefits computation was given, which shows necessity of energy conservation fromaspect of reactive power compensation. The weak links of transformer energy conservation methods were discussed and thefuture relation research directions were prospected. It’s concluded that the individual line enterprises especially ones with highenergy consumption, should promote the application of new-type energy conservation transformers as soon as possible, and fullydig the energy conservation potential and improve the productive benefits.
