3、牽(qian)引變電模型

    沙盤設置2個(ge)牽引變(bian)電所（1#、2#）、1個(ge)開閉所（主供車(che)站(zhan)2#側線(xian)）、2個(ge)分區(qu)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(ji)聯鎖及牽引(yin)供電系統操作臺

       系統實(shi)現牽引變電(dian)所、開閉所、分(fen)區所的(de)(de)計算機綜合控制(zhi)(zhi)功(gong)能(neng)(neng)。利用計算機控制(zhi)(zhi)軟(ruan)件(jian)實(shi)現對(dui)牽引供(gong)電(dian)的(de)(de)控制(zhi)(zhi)。真實(shi)再現牽引供(gong)電(dian)在不同運行方式和運行狀態(tai)下控制(zhi)(zhi)及操作功(gong)能(neng)(neng)，通過軟(ruan)件(jian)界面實(shi)現真實(shi)供(gong)電(dian)系統的(de)(de)調度仿真。
