3、牽引(yin)變電模型

    沙盤設置2個(ge)牽(qian)引變電所（1#、2#）、1個(ge)開閉所（主供車站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(lian)鎖及(ji)牽引供電(dian)系統操作臺

       系統實(shi)現(xian)牽引(yin)(yin)變電(dian)所、開閉(bi)所、分區所的計算機綜合控制(zhi)功(gong)能。利用計算機控制(zhi)軟(ruan)件實(shi)現(xian)對牽引(yin)(yin)供電(dian)的控制(zhi)。真實(shi)再現(xian)牽引(yin)(yin)供電(dian)在不(bu)同運行方(fang)式和運行狀(zhuang)態(tai)下控制(zhi)及操作功(gong)能，通過軟(ruan)件界面(mian)實(shi)現(xian)真實(shi)供電(dian)系統的調(diao)度仿(fang)真。
