3、牽引(yin)變(bian)電模型(xing)

    沙盤設置2個牽引變(bian)電(dian)所(suo)(suo)（1#、2#）、1個開閉所(suo)(suo)（主供車站2#側線）、2個分區所(suo)(suo)；采用彩色有機玻璃雕刻技術，來模擬牽引變電所的房屋。

4、微機聯鎖及牽引供電系統操作(zuo)臺(tai)

       系(xi)統(tong)(tong)實現(xian)牽(qian)引變(bian)電所、開閉所、分(fen)區所的計算機綜合控(kong)制(zhi)功(gong)(gong)能。利用(yong)計算機控(kong)制(zhi)軟件實現(xian)對牽(qian)引供電的控(kong)制(zhi)。真(zhen)(zhen)實再現(xian)牽(qian)引供電在不同運行(xing)方式和運行(xing)狀態下(xia)控(kong)制(zhi)及操作功(gong)(gong)能，通過軟件界面實現(xian)真(zhen)(zhen)實供電系(xi)統(tong)(tong)的調度仿真(zhen)(zhen)。
