3、牽引變電模(mo)型(xing)

    沙盤設置2個牽引變電所（1#、2#）、1個開閉所（主供車站2#側線）、2個分區所；采用彩色有機玻璃雕刻技術，來模擬牽引變電所的房屋。

4、微機聯鎖及牽引供電(dian)系(xi)統(tong)操(cao)作臺

       系(xi)統實(shi)現牽(qian)引(yin)(yin)變電所、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)軟件實(shi)現對牽(qian)引(yin)(yin)供電的控制(zhi)。真實(shi)再現牽(qian)引(yin)(yin)供電在(zai)不(bu)同運(yun)行方(fang)式(shi)和(he)運(yun)行狀態(tai)下控制(zhi)及操作功(gong)能，通過軟件界面(mian)實(shi)現真實(shi)供電系(xi)統的調度仿真。
