  自動調壓方法

  自動(dong)(dong)調(diao)(diao)(diao)壓方法是通(tong)過幾個(ge)自動(dong)(dong)控(kong)制裝置(zhi)使(shi)輸出電(dian)(dian)壓穩定在設定范圍(wei)內。自動(dong)(dong)調(diao)(diao)(diao)壓方法分為電(dian)(dian)氣自動(dong)(dong)調(diao)(diao)(diao)壓方法和電(dian)(dian)子自動(dong)(dong)調(diao)(diao)(diao)壓方法兩種。

  1.電(dian)氣(qi)自動調(diao)壓(ya)方法

  電(dian)(dian)(dian)氣自動調(diao)節方法是利用電(dian)(dian)(dian)氣傳動和控制實現輸出(chu)電(dian)(dian)(dian)壓自動調(diao)節的(de)方法。主要(yao)通過(guo)可變電(dian)(dian)(dian)阻、感應電(dian)(dian)(dian)壓等(deng)元件調(diao)整(zheng)電(dian)(dian)(dian)路參數,調(diao)整(zheng)輸出(chu)電(dian)(dian)(dian)壓。

  將可變電阻器連接到油浸式變壓器的繞組上,根據油浸式變壓器的(de)(de)輸出(chu)電(dian)(dian)(dian)(dian)壓(ya)的(de)(de)變(bian)(bian)化自動(dong)調(diao)壓(ya)可(ke)(ke)變(bian)(bian)電(dian)(dian)(dian)(dian)阻(zu)器的(de)(de)電(dian)(dian)(dian)(dian)阻(zu)值(zhi),從(cong)而(er)達到調(diao)整輸出(chu)電(dian)(dian)(dian)(dian)壓(ya)的(de)(de)目(mu)的(de)(de)。典型(xing)的(de)(de)可(ke)(ke)變(bian)(bian)電(dian)(dian)(dian)(dian)阻(zu)器包括旋轉電(dian)(dian)(dian)(dian)位(wei)計(ji)和調(diao)整電(dian)(dian)(dian)(dian)位(wei)計(ji)。旋轉電(dian)(dian)(dian)(dian)位(wei)計(ji)可(ke)(ke)以(yi)通過旋轉手柄手動(dong)調(diao)節,調(diao)節電(dian)(dian)(dian)(dian)位(wei)計(ji)可(ke)(ke)以(yi)通過一(yi)些(xie)電(dian)(dian)(dian)(dian)路控(kong)制方法自動(dong)調(diao)節。調(diao)整可(ke)(ke)變(bian)(bian)電(dian)(dian)(dian)(dian)阻(zu)器自動(dong)調(diao)壓(ya)輸出(chu)電(dian)(dian)(dian)(dian)壓(ya)的(de)(de)方法稱為“分壓(ya)電(dian)(dian)(dian)(dian)路自動(dong)調(diao)壓(ya)方法”。

  2.油浸式變壓器電子自動調壓方法

  電子自動調節方法是現代電子技術實現自動調節的方法。可自動調節油浸式變壓器的輸入電流,實現(xian)輸出電壓調節。

  一般的電子自(zi)動(dong)調壓(ya)(ya)方(fang)法包括分壓(ya)(ya)自(zi)動(dong)調壓(ya)(ya)方(fang)法、定頻自(zi)動(dong)調壓(ya)(ya)方(fang)法、交流調壓(ya)(ya)靜態定壓(ya)(ya)方(fang)法等。這些方(fang)法通過(guo)使用電子部(bu)件代替機械(xie)可(ke)變電阻(zu)器并通過(guo)反饋電路實現(xian)自(zi)動(dong)調節來實現(xian)。
