农网改造中变压器选型方案的新模式

a Novel Selecting and Collocating Scheme of Transformer in the Reconstruction of Rural Power System

依据当前我国农村电网的某些特点,文中介绍了一种可靠性较高、节能效果显著、技术经济性较好的D/Y变换调容变压器的技术特点及其在农网改造中的应用,并对变压器损耗及其在相同情况下使用常用的电力变压器的技术指标进行了对照分析,得出在农网改造中,使用这一新型变压器选型方案,不仅可克服当前农村电网的某些不足,还可对以后的增容留有一定的灵活性。

According to the characteristics of rural power system ,a technology traits and application of some D/Y adjustable capacity distribution transformer is introduced in this paper ,which is used in the reconstruction of rural power system with relative high reliability, an obvious effect of energy-saving and good technical economy. The correlative principle of this transformer is illustrated and its indexes are analyzed comparing with some other types of general transformers, then get a conclusion that the novel selecting and collocating scheme of transformer will not only overcome the shortages of the current rural power system, but also keep some flexible room for the future expansion in the reconstruction of rural power system.
