safety andeconomic operation of the electric power system, is the middle

link of power plants and users,plays the role of transformation and distribution

of electric energy.

The main design object for the designed to 110kV step-down

substation substation main wiring, determine the original data

analysis substation; load calculation is determined bynumber, capacity and

type of main transformer. According to the short circuit

calculationresults, the primary equipment of substation selection and

calibration of. At the same time to complete the design scheme of lightning

protection and earthing device.
