摘　　要：变压器是电网中最重要的电力设备,其数量多,总的电能损耗很大。据统计,配电变压器的电能损耗约占输配电系统电能损耗的30%,因此,降低配电变压器的能耗,已成为最重要最紧迫的任务之一。针对低压配电变压器的节能关键技术进行研究,分析配电变压器各种损耗的产生机理以及降低损耗的方法,对现有配电变压器运行特点和数据加以对比研究和数据挖掘,优化调整配电网运行电压和智能控制三相负荷实时平衡,实现配电变压器节能降耗经济调度运行目标,是节能降耗的重要技术,具有较大的工程实际研究意义。Transformer is the most important power equipment in the power grid,in which many transformers are used and the total power loss is great. Thereby,to reduce the energy consumption for power distribution transformer has become one of the most urgent tasks. The energy-saving key technology of low-voltage distribution transformer is studied in this paper. Each loss mechanism of distribution transformer and method of loss reduction are analyzed. The operation characteristics and data of the existing distribution transformers are contrasted,and data mining is performed. The operating voltage of distribution network was optimized. The intelligent control of three-phase load real-time balance was adopted. The goal of energy-saving and loss reduction of distribution transformer was realized.
