The electrical host wiring design is the transformer substation electricity design main body, in the design should take the project description as the basis, take the national economic construction policy, the policy, the technical stipulation, the standard as the criterion, the union project actual situation in the guarantee power supply reliable, the dispatcher nimble, satisfies each specification under the premise to give dual attention to the movement, the maintenance is convenient, as far as possible saves the investment. The conductor and the electrical equipment choice is one of electrical design main contents, in the electrical power system each kind of electrical equipment function and the working condition are dissimilar, concrete choice method quite same not less than, but all has the unanimous request to them, the electrical equipment must be able the reliable work, must carry on the choice according to the regular service condition, and according to shortcircuits the condition to verify the thermally stable and to move stably. The power distribution equipment is according to the electrical host wiring connection way, by the switch electric appliance, the protection and the survey electric appliance, the generator and the essential supporting facility sets up the overall installment which but bees. By this design looked 110KV suitably uses outdoor form, 35KV and 10KV suitably uses in the room the form. In order to prevent with the limit thunder and lightning hazardous 河南理工大學(xué)萬(wàn)方科技學(xué)院畢業(yè)設(shè)計(jì)/論文IV nature, in the transformer substation also should use the antiradar measure and the antiradar protective device.Key words: circuit breaker disconnect switch switchyard lightning arrester 目 錄前 言 ......................................................................................................11 電力系統(tǒng)概述 ....................................................................................3 電力系統(tǒng)分析 .........................................................................3 變電站總體分析 .....................................................................5 建設(shè)規(guī)模 ......................................................................5河南理工大學(xué)萬(wàn)方科技學(xué)院畢業(yè)設(shè)計(jì)/論文V 選址概況 ......................................................................5 負(fù)荷分析 .................................................................................52 主變壓器的選擇 ................................................................................8 主變?nèi)萘窟x擇應(yīng)考慮問(wèn)題 .....................................................8 主變額定容量的選擇計(jì)算 .....................................................8 變壓器相數(shù)的形式的選擇 .....................................................9 變壓器相數(shù)的選擇 ......................................................9 繞組數(shù)和繞組連接方式的選擇 ..................................9 主變阻抗和調(diào)壓方式的選擇 ....................................10 容量比 ........................................................................10 變壓器各側(cè)電壓的選擇 ............................................103 電氣主接線設(shè)計(jì) ..............................................................................11 電氣主接線設(shè)計(jì) ...................................................................11 主接線設(shè)計(jì)應(yīng)該考慮的基本問(wèn)題 .......................................11 主接線的設(shè)計(jì)步驟 ................................................................12 110V 電壓等級(jí)接線方式的確定 .............................12 35KV 電壓等級(jí)主接線的分析設(shè)計(jì) .......................13 10KV 電壓等級(jí)主接線的確定 ...............................144 短路電流的計(jì)算 ..............................................................................16 選擇基準(zhǔn)容量 .......................................................................16 計(jì)算各線路電抗 ...................................................................17 對(duì)應(yīng)的標(biāo)幺值 .......................................................................17 系統(tǒng)電抗 ...............................................................................17 各電壓側(cè)計(jì)算 .......................................................................185 電氣設(shè)備的選擇 ..............................................................................24 電器選擇 ...............................................................................24 導(dǎo)體和絕緣子 ............................................................24 電氣設(shè)備 ....................................................................24 選擇導(dǎo)體和電器設(shè)備的技術(shù)條件 .......................................24 母線選擇和負(fù)荷出線選擇的計(jì)算過(guò)程 ...............................25 110KV 母線選擇 ......................................................25 110KV 側(cè)主變引下線 ..............................................26 35KV 母線發(fā)熱及 穩(wěn)定性較驗(yàn)計(jì)算書 ....................27 35KV 側(cè)主變引下線的計(jì)算 ................................
