3、牽引變電模型

    沙盤設置2個(ge)牽(qian)引變電所(suo)（1#、2#）、1個(ge)開閉所(suo)（主供(gong)車(che)站2#側線）、2個(ge)分區所(suo)；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(lian)鎖及(ji)牽引供(gong)電系統操作臺

       系統實(shi)現牽引變電所、開閉所、分(fen)區所的計算機綜合控制功(gong)能。利用計算機控制軟件實(shi)現對(dui)牽引供(gong)電的控制。真實(shi)再現牽引供(gong)電在(zai)不同運行(xing)(xing)方式和運行(xing)(xing)狀態下(xia)控制及操作功(gong)能，通過軟件界面實(shi)現真實(shi)供(gong)電系統的調度仿(fang)真。
