3、牽引變(bian)電模型

    沙盤設置2個(ge)牽引(yin)變電所（1#、2#）、1個(ge)開閉所（主供車站2#側線）、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、微機聯鎖(suo)及牽引供(gong)電系統操作臺

       系統實現牽引變電所、開(kai)閉所、分區所的計(ji)算(suan)機綜合控(kong)(kong)制功能(neng)。利(li)用計(ji)算(suan)機控(kong)(kong)制軟件實現對牽引供(gong)電的控(kong)(kong)制。真實再現牽引供(gong)電在不同運行方式和運行狀態下控(kong)(kong)制及操作功能(neng)，通過軟件界面實現真實供(gong)電系統的調度仿真。
