Research on Application of Single-phase Distribution Transformer in Urban Lower-voltage Grid

This paper introduces the application condition and advantages of single-phase distribution transformer in urban lower-voltage grid.With the analysis of the structure of single-phase distribution transformer and the way of power supply of the single-phase distribution system,the paper points out the attentions in the application of single-phase distribution transformer in the urban lower-voltage grid,and puts forward the proposal that in the construction and reconstruction of the urban lower-voltage grid,the way of power supply combining single-phase distribution transformer and three-phase one should be formed with the consideration of the real situation.
