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)（主供車站2#側(ce)線）、2個分區(qu)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(ji)牽引供電(dian)系統操作(zuo)臺

       系統(tong)實現牽引(yin)(yin)變電(dian)(dian)所、開閉(bi)所、分區所的計算機(ji)綜合控(kong)制(zhi)(zhi)功(gong)(gong)能。利(li)用計算機(ji)控(kong)制(zhi)(zhi)軟(ruan)件(jian)實現對牽引(yin)(yin)供電(dian)(dian)的控(kong)制(zhi)(zhi)。真實再現牽引(yin)(yin)供電(dian)(dian)在不(bu)同運行方式和(he)運行狀態下控(kong)制(zhi)(zhi)及操作功(gong)(gong)能，通(tong)過軟(ruan)件(jian)界面實現真實供電(dian)(dian)系統(tong)的調度仿真。
