3、牽引(yin)變電模型(xing)

    沙盤設置2個(ge)牽引變電(dian)所（1#、2#）、1個(ge)開閉所（主供車站2#側線）、2個(ge)分(fen)區所；采用彩色有機玻璃雕刻技術，來模擬牽引變電所的房屋。

4、微機(ji)聯鎖及牽(qian)引供(gong)電系(xi)統操作(zuo)臺

       系統實(shi)現牽引(yin)(yin)變電所、開閉所、分(fen)區所的(de)(de)計算機綜合控(kong)制(zhi)(zhi)功(gong)能。利用計算機控(kong)制(zhi)(zhi)軟件(jian)實(shi)現對牽引(yin)(yin)供電的(de)(de)控(kong)制(zhi)(zhi)。真(zhen)實(shi)再現牽引(yin)(yin)供電在不(bu)同運行(xing)方式和運行(xing)狀態下控(kong)制(zhi)(zhi)及操作功(gong)能，通(tong)過軟件(jian)界面實(shi)現真(zhen)實(shi)供電系統的(de)(de)調度仿真(zhen)。
