3、牽引變(bian)電模型

    沙盤設置2個牽引變電所(suo)(suo)（1#、2#）、1個開(kai)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(lian)鎖及牽引(yin)供電(dian)系統操作臺

       系統(tong)實(shi)現(xian)牽(qian)引變電(dian)(dian)所(suo)、開閉所(suo)、分(fen)區所(suo)的(de)計算機(ji)綜(zong)合控(kong)制(zhi)功能(neng)。利用計算機(ji)控(kong)制(zhi)軟件實(shi)現(xian)對牽(qian)引供(gong)電(dian)(dian)的(de)控(kong)制(zhi)。真實(shi)再現(xian)牽(qian)引供(gong)電(dian)(dian)在(zai)不同(tong)運行(xing)(xing)方式和運行(xing)(xing)狀態下控(kong)制(zhi)及操作(zuo)功能(neng)，通過(guo)軟件界(jie)面實(shi)現(xian)真實(shi)供(gong)電(dian)(dian)系統(tong)的(de)調度仿真。
