Here period, all kinds problems that meet all passes to pare, check to calculate again and again, and ask the can solution in teacher. Graduate to design the thesis from design the manual, design calculation book, a set of diagrams paper( the electricity lord connects the line diagram, total flat surface arranges the diagram and go together with electricity equip cross section diagram, defend thunder protection diagram) constitute. The contents is more detailed, to from now on extend to consults certainly value. For this year, electric power is in international munity energy with economy develop of the function increases increasingly, it have bee modern the society is practical the most widely and need the quickest energy. Change the reasonable design that give or get an electric shock are a with developments very constituting the part importantly. This design is at guiding teacher descend, passing oneself of design what argument plete with meticulous care. Whole design process inside, pletely dependable, economic, 沈陽(yáng)工業(yè)大學(xué)畢業(yè)設(shè)計(jì) （ 論文 ） － VI－ vivid...etc. many factors that meticulous consideration engineering design, end plete this design project. Pass to plete this graduate design the thesis, further appreciating the our country the policy idea of electric power industry developments with the economic standpoint, educates to proceed to the engineering technique, economy more pletely to synthesize the analytical skill.
