3、牽引變電(dian)模型

    沙盤設置2個牽(qian)引(yin)變電所(suo)(suo)（1#、2#）、1個開閉所(suo)(suo)（主供車站2#側線）、2個分區所(suo)(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、微機聯鎖及(ji)牽引供電系統操作臺

       系統實(shi)現牽(qian)引(yin)變電(dian)(dian)所(suo)、開閉所(suo)、分區(qu)所(suo)的(de)計(ji)算(suan)機綜合控制功能。利用計(ji)算(suan)機控制軟件(jian)實(shi)現對牽(qian)引(yin)供電(dian)(dian)的(de)控制。真實(shi)再現牽(qian)引(yin)供電(dian)(dian)在不(bu)同運行方式和運行狀態(tai)下控制及操(cao)作功能，通過軟件(jian)界(jie)面實(shi)現真實(shi)供電(dian)(dian)系統的(de)調度仿真。
