3、牽引變電(dian)模型

    沙盤設置2個牽引變電所(suo)(suo)（1#、2#）、1個開閉所(suo)(suo)（主(zhu)供車站2#側(ce)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(ji)聯鎖及牽引供(gong)電系統(tong)操作臺

       系統(tong)(tong)實現牽(qian)引(yin)變電所(suo)、開(kai)閉所(suo)、分區(qu)所(suo)的計算機綜合控制(zhi)(zhi)功能(neng)。利用(yong)計算機控制(zhi)(zhi)軟件實現對牽(qian)引(yin)供(gong)電的控制(zhi)(zhi)。真(zhen)實再(zai)現牽(qian)引(yin)供(gong)電在不(bu)同運行方(fang)式和運行狀(zhuang)態下控制(zhi)(zhi)及操(cao)作功能(neng)，通過軟件界面(mian)實現真(zhen)實供(gong)電系統(tong)(tong)的調度仿真(zhen)。
