As the title of this paper is intended, not the transformation of the actual project, so this paper some of the views are not necessarily the actual situation for our school district. First of all, according to mandate of the book, so that the sum of the proposed substation and the outlet direction to consider, and through the analysis of load data, security, economic and reliability considerations, identified the main 10kV and electricity connection points, and then Load Calculation and supply area through the main transformer station to determine the number, capacity and model, but also to determine the capacity of the station, transformers and model, then, the maximum continuous operating current and short circuit calculation results, on the high-voltage fuse, isolating switch, bus, insulators and wall bushings, voltage transformers, current transformers for the selection, thus completing the first part of the 10kV electrical design. Finally, the maximum continuous operating current and short circuit calculation results, make line protection, transformer protection, bus protection, lightning protection. Thus completing the second part of the 10kV el
