本設(shè)計(jì)共有四部分：第一部分為設(shè)計(jì)任務(wù)書；第二部分畢業(yè)設(shè)計(jì)（論文）說明及計(jì)算書；第三部分為變電站的其他規(guī)劃；第四部分為設(shè)計(jì)圖紙。
此次設(shè)計(jì)的是一個(gè)降壓變電所，有三個(gè)電壓等級(jí)，主變?nèi)萘繛?X31.5MVA。110KV主接線為雙母線、35KV和10KV主接線均為單母分段 ，本次設(shè)計(jì)中進(jìn)行了主接線的方案論證、短路電流計(jì)算、主要電氣設(shè)備的選擇有斷路器、隔離開關(guān)、母線、PT、CT等的選擇及校驗(yàn)。



The design is made up of four parts: part one, the design specification; part two, the prospectus of the design and the calculations of the design; part three,construction of power substation; part four, the design drawing.
The design concerns a step-down substation of three voltages with the main capacity of 2X31.5MVA. Its main line of 110KV is a two-way bus, and the other two of 35KV and 10KV are both one-way bus line sections. As for the design, the thesis has verified its wiring project, calculated its short-circuit current, selected and tested its main electrical equipments like the circuit breaker, the disconnecting switch, the bus line, PT, CT, etc.
I would like to express my thanks to the supervisor, Mr. for his invaluable assistance. Since this is a tentative design, the criticism and advice of all my teachers and schoolmates are welcome for its improvement.
