3、牽引變(bian)電模型(xing)

    沙盤設置2個牽引變電所（1#、2#）、1個開閉所（主(zhu)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(suo)及牽引供(gong)電系(xi)統操作(zuo)臺

       系統實(shi)(shi)現牽引(yin)變電所(suo)、開閉所(suo)、分區(qu)所(suo)的(de)計算(suan)機(ji)綜合(he)控(kong)制(zhi)功能。利用計算(suan)機(ji)控(kong)制(zhi)軟(ruan)件實(shi)(shi)現對牽引(yin)供電的(de)控(kong)制(zhi)。真實(shi)(shi)再(zai)現牽引(yin)供電在不(bu)同運(yun)行方式(shi)和(he)運(yun)行狀態下控(kong)制(zhi)及操作功能，通過(guo)軟(ruan)件界面(mian)實(shi)(shi)現真實(shi)(shi)供電系統的(de)調度仿(fang)真。
