某電機(jī)修造廠總降壓變電所及其高壓配電系統(tǒng)設(shè)計(jì)

1、#摘要電力行業(yè)作為國(guó)家經(jīng)濟(jì)的命脈之一，無(wú)論在工農(nóng)業(yè)建設(shè)還是普通民用都扮演著中流砥柱的作用，為社會(huì)主義現(xiàn)代建設(shè)奠定了堅(jiān)實(shí)的基礎(chǔ)。宏觀意義電力行業(yè)需要通過(guò)客觀縝密的工廠供配電系統(tǒng)設(shè)計(jì)體現(xiàn)，這是本設(shè)計(jì)的價(jià)值所在。本設(shè)計(jì)內(nèi)容針對(duì)鄭州某電機(jī)修造廠的供配電設(shè)計(jì)，據(jù)任務(wù)書(shū)要求，通過(guò)查閱相關(guān)資料文獻(xiàn)，運(yùn)用大學(xué)階段學(xué)習(xí)成果，通過(guò)具體討論工廠配電系統(tǒng)方案設(shè)計(jì)的原理，進(jìn)行總體設(shè)計(jì)和詳細(xì)分析說(shuō)明，包括：負(fù)荷計(jì)算和無(wú)功功率補(bǔ)償、變電所位置和型式的選擇、變電所主變

2、壓器臺(tái)數(shù)和容量、類型的選擇、變電所主接線方案、短路電流的計(jì)算、變電所一次設(shè)備的選擇與校驗(yàn)、變電所出線的選擇、變電所二次回路方案的選擇與繼電保護(hù)的整定、防雷保護(hù)與接地裝置。以科學(xué)嚴(yán)謹(jǐn)?shù)姆椒ㄍ瓿杀驹O(shè)計(jì)的內(nèi)容，達(dá)到設(shè)計(jì)任務(wù)書(shū)的要求，將電力行業(yè)中的單元組成——工廠供配電系統(tǒng)設(shè)計(jì)反應(yīng)出來(lái)。關(guān)鍵詞：負(fù)荷計(jì)算短路電流計(jì)算主接線方案繼電保護(hù)整定防雷和接地#ABSTRACTPowerindustryasthelifebloodofthenationale
