3、牽引變電模型

    沙盤設置2個牽引變電所（1#、2#）、1個開閉(bi)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)及牽引供電系統操(cao)作(zuo)臺

       系(xi)統(tong)實現(xian)牽(qian)引(yin)變電所(suo)、開閉(bi)所(suo)、分區所(suo)的(de)計(ji)算(suan)機綜合控(kong)制(zhi)(zhi)功能。利用(yong)計(ji)算(suan)機控(kong)制(zhi)(zhi)軟件實現(xian)對牽(qian)引(yin)供(gong)電的(de)控(kong)制(zhi)(zhi)。真(zhen)實再現(xian)牽(qian)引(yin)供(gong)電在不同運(yun)行(xing)方式和(he)運(yun)行(xing)狀態下控(kong)制(zhi)(zhi)及操作功能，通(tong)過軟件界面(mian)實現(xian)真(zhen)實供(gong)電系(xi)統(tong)的(de)調(diao)度仿(fang)真(zhen)。
