3、牽引變(bian)電模型

    沙盤設置2個牽引(yin)變(bian)電所（1#、2#）、1個開閉所（主供車站2#側線）、2個分區所；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)引供電系統(tong)操(cao)作臺(tai)

       系統實現牽引變電所、開(kai)閉所、分區(qu)所的(de)(de)計算機綜合控(kong)制(zhi)功(gong)能。利用計算機控(kong)制(zhi)軟件(jian)(jian)實現對牽引供(gong)電的(de)(de)控(kong)制(zhi)。真(zhen)實再現牽引供(gong)電在不同運行方式(shi)和運行狀態下控(kong)制(zhi)及操作(zuo)功(gong)能，通過軟件(jian)(jian)界面實現真(zhen)實供(gong)電系統的(de)(de)調度(du)仿真(zhen)。
