3、牽引變電模(mo)型

    沙盤設置2個牽引變電所（1#、2#）、1個開閉所（主供車站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、微機聯鎖及牽引供電系統操作臺

       系統實(shi)(shi)現牽(qian)引變電所(suo)、開閉所(suo)、分區所(suo)的計(ji)算(suan)機綜合控制功(gong)能。利用計(ji)算(suan)機控制軟件(jian)實(shi)(shi)現對牽(qian)引供(gong)電的控制。真實(shi)(shi)再現牽(qian)引供(gong)電在不(bu)同運行方式和運行狀態下控制及操作功(gong)能，通過軟件(jian)界面實(shi)(shi)現真實(shi)(shi)供(gong)電系統的調度(du)仿真。
