220kv變電站設(shè)計-畢業(yè)論文

1、220kV220kV變電站設(shè)計變電站設(shè)計摘要摘要隨著我國可以發(fā)展，特別是計算機(jī)的進(jìn)步，電力系統(tǒng)對變電站的要求越來越高。本設(shè)計討論的是220kV變電站電氣部分的設(shè)計。首先對原資料進(jìn)行分析，選擇主變壓器，在此基礎(chǔ)上進(jìn)行主接線設(shè)計，在進(jìn)行短路計算，選擇設(shè)備，然后進(jìn)行防雷接地以及保護(hù)，配電裝置設(shè)計。關(guān)鍵詞關(guān)鍵詞：設(shè)備選擇；短路計算；防雷接地；主接線；電氣平面布置；互感器；隔離開關(guān)；3（一）原始資料分析......................
