3、牽引變電模型

    沙盤設置2個牽(qian)引變電所（1#、2#）、1個開閉所（主供車站2#側線(xian)）、2個分區(qu)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(wei)機聯鎖及牽引供電系統(tong)操作臺

       系統(tong)(tong)實現牽(qian)引(yin)變(bian)電(dian)(dian)所、開閉所、分區(qu)所的(de)(de)計算機綜合(he)控(kong)制(zhi)(zhi)功能(neng)。利(li)用計算機控(kong)制(zhi)(zhi)軟(ruan)件實現對牽(qian)引(yin)供(gong)電(dian)(dian)的(de)(de)控(kong)制(zhi)(zhi)。真(zhen)(zhen)實再(zai)現牽(qian)引(yin)供(gong)電(dian)(dian)在不同運行方式和運行狀態下控(kong)制(zhi)(zhi)及(ji)操作功能(neng)，通過軟(ruan)件界面實現真(zhen)(zhen)實供(gong)電(dian)(dian)系統(tong)(tong)的(de)(de)調度(du)仿真(zhen)(zhen)。
