【正文】 以上三種方案，從經濟性、可靠性等多方面因素考慮，最佳設計方案為方案（一）。 優(yōu)點：高壓電器少，布置簡單，造價低，經適當布置可較容易地過渡成單母線分段或雙母線分 接線。 2） 靈活性：其含義是電氣主接線能適應各種運行方式（包括正常、事故和檢修運行方式） 并能方便地通過 操作實現(xiàn)運行方式的變換而且在基本一回路檢修時，不影響其他回路繼續(xù)運行，靈活性還應包括將來擴建的可能性。由于地處杭州所以交通方便，有充足水源，而且由于杭州地下無地震帶和地震區(qū)，所以對于防震等級的選擇可以適當降低。 關鍵詞 ： 變電站 負荷 輸電系統(tǒng) 配電 系統(tǒng) 高壓網絡 補償裝置 武漢大學珞珈學院本科畢業(yè)論文 II 110kV Substation primary equipment design Abstract Along with the economic development and the modern industry developments of quick rising, the design of the power supply system bee more and more pletely and system. Because the quickly increase electricity of factories, it also increases seriously to the dependable index of the economic condition, power supply in quantity. Therefore they need the higher and more perfect request to the power supply. Whether Design reasonable, not only affect directly the base investment and circulate the expenses with have the metal depletion in color metal, but also will reflect the dependable in power supply and the safe in many facts. In a word, it is close with the economic performance and the safety of the people. 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. 武漢大學珞珈學院本科畢業(yè)論文 III The region of 110voltage effect many fields and should consider many problems. Analysis 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. At the same time following the choice of every kind of transformer, then make sure the line method of the transformer substation, then calculate the shortcircuit electric current, choosing to send together with the electric wire method and the style of the wire, then proceeding the calculation of shortcircuit electric current. This first step of design included:(1) ascertain the total project (2) load analysis(3) the calculation of the shortcircuit electric current (4) the design of an electric shock the system design to connect with system and the choice of line project (5) the choice and the settle of the protective facility (6) the contents to defend the thunder and protection of connect the earth. Along with the high and quick development of electric power technique, electric power system then can change from the generate of the electricity to the supply the power. Key words: Substation Load Transmission system Distribution High voltage work Correction equipment. 武漢大學珞珈學院本科畢業(yè)論文 目 錄 前 言 ........................................................................ 1 緒 論 ........................................................................ 2 第一章 電氣主接線 主接線的 選擇 ............................................................................................................... 3 110kV電氣主接線 ....................................................................................................... 4 35kV電氣主接線 ........................................................................................................ 5 10kV電氣主接線 ........................................................................................................... 6 站用電接線 ................................................................................................................... 7 第二章 負荷計算及變壓器選擇 負荷計算 ...................................................................................................................... 9 負荷分類及定義 ................................................................................................... 9 負荷組成 ............................................................................................................. 9 主變臺數(shù)、容量和型式的確定 ...................................................................................... 11 2． 3 變電所主變壓器容量的確定 .......................................................................................12 2． 4 變電站主變壓器型式的選擇 .......................................................................................12 第三章 最大持續(xù)工作電流及短路電流的計算 各回路最大持續(xù)工作電流 .............................................................................................14 短路電流計算點的確定 ................................................................................................14 短路電流計算的目的 ....................................................................................................14 短路電流計算的步驟 ....................................................................................................15 電流計算結果 ..............................................................................................................16 第四章 主要電氣設備選擇 高壓斷路器的選擇 .....................................................................................................20 隔離開關的選擇 ...........................................................................................................21 各級電壓母線的選擇 ..................................................................................................22 絕緣子和穿墻套管的選擇 .............................................................................................22 電流互感器的配置和選擇 .............................................................................................22 電壓互感器的配置和選擇 ..............................
