【正文】 c situation. Second chapter is shoulders the putation and the transformer choice, carries on the load putation according to the known transformer substation load material to the transformer substation. Through the load which obtains had determined the host changes the capacity and a number, the host change the pattern, the winding wiring way, the accent press the way and the host changes the impedance. Third chapter is the transformer substation electricity host wiring design, separately through to 10kV side electricity host wiring drawing up, chooses the stablest reliable wiring way. Fourth chapter is the short class putation, first determined shortcircuits the spot, calculates various parts reactance, then to respectively shortcircuits separately to carry on the putation, obtains respectively shortcircuits the shortcircuit current. Fifth chapter is the electrical equipment choice, the electrical equipment including the generatrix, the circuit breaker, the isolator, the electric current and the voltage transformer, the fuse. Sixth chapter is the power distribution equipment, mainly carries on the design to the transformer substation power distribution equipment. Seventh chapter is antiradar with the earth, this chapter has carried on the choice to the arrester, as well as has determined the earth way. Through to the 10kV transformer substation design, causes me has to the electrical engineering and its the automated specialized branch curriculum to be prehensive, system grasping, strengthened apply theory to reality the ability, raised the project consciousness, exercised me independently to analyze and the solution electric power project design question ability.
