3、牽引變電模型

    沙盤設置2個(ge)牽引變電(dian)所（1#、2#）、1個(ge)開閉所（主供(gong)車站2#側線(xian)）、2個(ge)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(ji)聯鎖及牽引供電系統操(cao)作臺(tai)

       系(xi)統實(shi)現(xian)(xian)牽(qian)(qian)引變(bian)電所、開閉所、分(fen)區所的(de)計算機綜合控(kong)制(zhi)功能(neng)。利(li)用計算機控(kong)制(zhi)軟(ruan)件實(shi)現(xian)(xian)對牽(qian)(qian)引供(gong)(gong)(gong)電的(de)控(kong)制(zhi)。真實(shi)再現(xian)(xian)牽(qian)(qian)引供(gong)(gong)(gong)電在(zai)不同運(yun)行方式和運(yun)行狀(zhuang)態(tai)下(xia)控(kong)制(zhi)及操作(zuo)功能(neng)，通過軟(ruan)件界面實(shi)現(xian)(xian)真實(shi)供(gong)(gong)(gong)電系(xi)統的(de)調度仿(fang)真。
