3、牽引變電(dian)模型(xing)

    沙盤設置2個牽引(yin)變(bian)電所（1#、2#）、1個開閉所（主供車站2#側線）、2個分區(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、微機聯鎖及牽引供電系統操作臺(tai)

       系統實現(xian)牽(qian)引(yin)變(bian)電(dian)所、開閉所、分區所的(de)計(ji)算機(ji)綜合控(kong)制(zhi)功能。利用計(ji)算機(ji)控(kong)制(zhi)軟(ruan)件實現(xian)對牽(qian)引(yin)供電(dian)的(de)控(kong)制(zhi)。真實再(zai)現(xian)牽(qian)引(yin)供電(dian)在不同運(yun)(yun)行方式和運(yun)(yun)行狀(zhuang)態下控(kong)制(zhi)及操作功能，通過(guo)軟(ruan)件界面實現(xian)真實供電(dian)系統的(de)調(diao)度(du)仿(fang)真。
