3、牽引變電模型(xing)

    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(dian)系(xi)統操作臺

       系(xi)統實現(xian)(xian)牽引變電(dian)(dian)所(suo)、開閉所(suo)、分區所(suo)的計(ji)算(suan)機綜合控(kong)制(zhi)(zhi)功(gong)能。利(li)用(yong)計(ji)算(suan)機控(kong)制(zhi)(zhi)軟件實現(xian)(xian)對(dui)牽引供(gong)電(dian)(dian)的控(kong)制(zhi)(zhi)。真(zhen)實再現(xian)(xian)牽引供(gong)電(dian)(dian)在不同運行方式和運行狀態下(xia)控(kong)制(zhi)(zhi)及操作功(gong)能，通(tong)過軟件界面實現(xian)(xian)真(zhen)實供(gong)電(dian)(dian)系(xi)統的調度仿(fang)真(zhen)。
