3、牽(qian)引(yin)變電模(mo)型

    沙盤設置2個(ge)牽引變(bian)電所（1#、2#）、1個(ge)開閉所（主供(gong)車站(zhan)2#側線(xian)）、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)牽引供電系統操作臺

       系統實(shi)現牽(qian)引(yin)變電(dian)所、開閉所、分區所的(de)(de)計算(suan)(suan)機綜合控(kong)(kong)制(zhi)功能(neng)。利用計算(suan)(suan)機控(kong)(kong)制(zhi)軟件實(shi)現對(dui)牽(qian)引(yin)供(gong)電(dian)的(de)(de)控(kong)(kong)制(zhi)。真實(shi)再現牽(qian)引(yin)供(gong)電(dian)在(zai)不同運行方式和運行狀態下控(kong)(kong)制(zhi)及操作功能(neng)，通過軟件界面實(shi)現真實(shi)供(gong)電(dian)系統的(de)(de)調(diao)度(du)仿真。
