With the development of modern civilization and progress of social production and life of the power supply, quality and management of the increasingly high demand. Factory power supply system is the core part of the substation. Therefore, the design and construction ofa safe and economical substation, it is extremely important. The power plant design include: the calculation of load and reactive pensation; substation main transformer station number and capacity, determine the types; Substation Main Wiring choice; into the outlet of choice; short-circuit calculations and switching equipment choice; secondary circuit and relay protection scheme for the selection and tuning; lightning protection and grounding design; workshop wiring scheme for the distribution line; Lines and distribution equipment and the choice of protective equipment; and electrical lighting design, and schematic drawing. Substation is on the electricity power system voltage and current to change, focus and allocation of places is essential for power system power transmission link, play bridge. 10kV substation is an important part of the power distribution is the key link in grid construction. . With the development of national economy, industrial and agricultural production growth requires an urgent increase in demand for power supply capacity, the proposed new 10kV substation. Substation is an important part of power
