更可靠和經(jīng)濟。通過使用自動封閉或自動切換來簡化電路的切換預(yù)留設(shè)施,可以快速無誤地冗余各個元素和使用設(shè)備。在為所有電壓設(shè)計工業(yè)企業(yè)的變電站時,應(yīng)考慮以下基本考慮事項:1.僅使用雙母線系統(tǒng)的單母線系統(tǒng)的優(yōu)選用途僅用于確??煽亢徒?jīng)濟的電力供應(yīng);2.廣泛使用組合式建筑和熱水器變電站;3.實際使用自動化和遙測技術(shù);如果變電站設(shè)計沒有設(shè)想使用自動化或遙測技術(shù),則電路布局方便將來添加此類設(shè)備,而無需過多投資和重新工作。4.使用簡單而便宜的設(shè)備-隔離開關(guān),短路開關(guān),負(fù)載隔離開關(guān),熔斷器,充分考慮其開關(guān)能力,可以大大減少對昂貴和關(guān)鍵的油,真空,螺線管和空氣開關(guān)的需求。變電站并且開關(guān)裝置電路是這樣制造的,即使用每條生產(chǎn)線的設(shè)備從各個變壓器,組件,線路饋送,以允許其與機構(gòu)同時斷開而不中斷相鄰生產(chǎn)流程的操作。在詳細(xì)描述變電站的電路時,最重要的任務(wù)是正確選擇和布置開關(guān)設(shè)備(開關(guān),隔離器,限流器,避雷器,高壓熔斷器)。這個決定取決于變電站的目的,功率和重要性。電力系統(tǒng)變電站是電力系統(tǒng)中不可或缺的重要組成部分,它承擔(dān)了電網(wǎng)安全轉(zhuǎn)換和分配任務(wù),經(jīng)濟運行起著決定性作用,是聯(lián)系用戶的發(fā)電廠和中間環(huán)節(jié)。隨著經(jīng)濟的發(fā)展,電網(wǎng)容量的不斷擴大,電網(wǎng)運行的可靠性要求越來越高。開發(fā)科技,智能開關(guān),光電式電流電壓互感器,運行狀態(tài)檢測,培訓(xùn)模擬變電站操作成熟等高新技術(shù),以及光纖技術(shù),計算機高速網(wǎng)絡(luò)系統(tǒng)等開發(fā)實時應(yīng)用,勢必對現(xiàn)有的變電站自動化技術(shù)產(chǎn)生深遠(yuǎn)的影響,是全數(shù)字化變電站自動化系統(tǒng)的發(fā)展趨勢。電力系統(tǒng)是由生產(chǎn),傳輸,分配和消耗各種功率的電力設(shè)備組成的。由于無法儲存大量的電力,我們必須確保電力和能源生產(chǎn)的平衡。隨著我國科技發(fā)展的科技進步達到一定水平。智能開關(guān),光電電流和電壓互感器,運行狀態(tài)檢測,培訓(xùn)模擬變電站操作等高新技術(shù),以及光纖技術(shù),計算機高速網(wǎng)絡(luò)系統(tǒng)在實時應(yīng)用開發(fā)中,顯著提高了自動化的轉(zhuǎn)化程度。我們的變電站電纜方案的設(shè)計趨向于簡單,許多國內(nèi)最近新建的220kV變電站和110
