3、牽引變(bian)電模(mo)型

    沙盤設置2個(ge)牽引變電所（1#、2#）、1個(ge)開閉(bi)所（主(zhu)供(gong)車站2#側線）、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、微機聯鎖及(ji)牽引(yin)供電系統操(cao)作臺

       系統(tong)實現(xian)牽(qian)(qian)引變電(dian)所(suo)、開閉所(suo)、分區所(suo)的計算機綜合控(kong)制(zhi)(zhi)功(gong)能(neng)。利(li)用計算機控(kong)制(zhi)(zhi)軟(ruan)件實現(xian)對(dui)牽(qian)(qian)引供電(dian)的控(kong)制(zhi)(zhi)。真(zhen)實再(zai)現(xian)牽(qian)(qian)引供電(dian)在不同(tong)運(yun)行(xing)方式和運(yun)行(xing)狀態(tai)下控(kong)制(zhi)(zhi)及操作功(gong)能(neng)，通過軟(ruan)件界面實現(xian)真(zhen)實供電(dian)系統(tong)的調度仿(fang)真(zhen)。
