3、牽引變電模型

    沙盤設置2個牽引變電所（1#、2#）、1個開(kai)閉所（主(zhu)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、微機聯鎖及牽引供(gong)電系統操(cao)作臺(tai)

       系統(tong)實現牽(qian)引(yin)變電(dian)所、開閉所、分區所的(de)(de)計(ji)算機綜(zong)合控(kong)制(zhi)(zhi)功(gong)能。利用計(ji)算機控(kong)制(zhi)(zhi)軟件實現對牽(qian)引(yin)供(gong)(gong)(gong)電(dian)的(de)(de)控(kong)制(zhi)(zhi)。真(zhen)實再現牽(qian)引(yin)供(gong)(gong)(gong)電(dian)在(zai)不同運行方式和(he)運行狀態下控(kong)制(zhi)(zhi)及操作功(gong)能，通(tong)過軟件界面實現真(zhen)實供(gong)(gong)(gong)電(dian)系統(tong)的(de)(de)調(diao)度仿真(zhen)。
