Because the quickly increase electricity of factories, it also increases seriously to the dependable index of the economic condition, power supply in quantity. The substation is an importance part of the electric power system, it is consisted of the electric appliances equipments and the Transmission and the Distribution. It obtains the electric power from the electric power system, through its function of transformation and assign, transport and safety. Then transport the power to every place with safe, dependable, and economical. As an important part of power’s transport and control, the transformer substation must change the mode of the traditional design and control, then can adapt to the modern electric power system, the development of modern industry and the of trend of the society life. The region of 110-voltage effect many fields and should consider many problems. Analyze change to give or get an electric shock a mission for carrying and customers carries etc. circumstance, choose the address, make good use of customer data proceed then carry calculation, ascertain the correct equipment of the customer.
