3、牽引變電模型

    沙盤設置2個牽引(yin)變電所（1#、2#）、1個開閉所（主供車站2#側(ce)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(suo)及牽(qian)引供電系(xi)統操作臺

       系(xi)統(tong)實現(xian)牽引變(bian)電所、開閉所、分區(qu)所的計(ji)算機(ji)綜合控(kong)(kong)制功能。利(li)用計(ji)算機(ji)控(kong)(kong)制軟(ruan)件(jian)(jian)實現(xian)對牽引供(gong)電的控(kong)(kong)制。真實再現(xian)牽引供(gong)電在不(bu)同運行(xing)方式和運行(xing)狀態下控(kong)(kong)制及操作功能，通(tong)過軟(ruan)件(jian)(jian)界面實現(xian)真實供(gong)電系(xi)統(tong)的調度仿真。
