Abstract The design of building general step-down substation and distribution system is based on the quantity and nature of the load of each equipment, the load requirement of production process and the layout of load, combined with the state power supply. To solve the problem of the safety and reliability of various departments and the energy distribution of the economy. The basic content of load calculation, selection of number and capacity building location total step-down power distribution room and main transformer, select the location number and capacity building general step-down power distribution room and main transformer, building general step-down power distribution between the main wiring design, the substation, grounding line, according to the load of the building from the technical and economic rationality, determine the distribution voltage calculation for buildings, buildings, power system short-circuit current, high voltage and low voltage side equipment, lightning protection device design.
Key words power supply and distribution system; primary design; transformer
