3、牽引(yin)變電模型

    沙盤設置2個牽引變電所（1#、2#）、1個開閉所（主供車站2#側線）、2個分(fen)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、微機聯鎖及牽引供(gong)電(dian)系統(tong)操(cao)作臺

       系統實(shi)現(xian)牽(qian)(qian)引變電所(suo)、開閉(bi)所(suo)、分區所(suo)的(de)計(ji)算(suan)機綜合(he)控(kong)制(zhi)功(gong)能(neng)。利(li)用計(ji)算(suan)機控(kong)制(zhi)軟件(jian)實(shi)現(xian)對牽(qian)(qian)引供電的(de)控(kong)制(zhi)。真實(shi)再(zai)現(xian)牽(qian)(qian)引供電在不(bu)同運行方式和運行狀態下控(kong)制(zhi)及操作功(gong)能(neng)，通過軟件(jian)界面實(shi)現(xian)真實(shi)供電系統的(de)調度(du)仿真。
