3、牽引變電模型

    沙盤設置2個牽引(yin)變(bian)電所（1#、2#）、1個開閉所（主供車(che)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、微機聯鎖及牽引供電系統操作臺

       系統(tong)(tong)實現牽引(yin)變電(dian)所、開閉(bi)所、分(fen)區所的計算機綜合控制(zhi)功能。利用計算機控制(zhi)軟(ruan)件(jian)(jian)實現對(dui)牽引(yin)供電(dian)的控制(zhi)。真實再(zai)現牽引(yin)供電(dian)在不同運(yun)行方式和運(yun)行狀態下控制(zhi)及操作功能，通(tong)過軟(ruan)件(jian)(jian)界面實現真實供電(dian)系統(tong)(tong)的調度仿真。
