3、牽引變電模型

    沙盤設置2個牽引變電(dian)所（1#、2#）、1個開閉所（主(zhu)供(gong)車站(zhan)2#側(ce)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系統操作臺

       系統(tong)實(shi)(shi)(shi)現牽引(yin)變電所、開(kai)閉所、分區所的(de)(de)計算(suan)機綜(zong)合控(kong)(kong)制(zhi)功能。利用計算(suan)機控(kong)(kong)制(zhi)軟件實(shi)(shi)(shi)現對牽引(yin)供電的(de)(de)控(kong)(kong)制(zhi)。真實(shi)(shi)(shi)再現牽引(yin)供電在不(bu)同運行方式(shi)和運行狀態下控(kong)(kong)制(zhi)及操作(zuo)功能，通過軟件界面實(shi)(shi)(shi)現真實(shi)(shi)(shi)供電系統(tong)的(de)(de)調度(du)仿真。
