3、牽(qian)引變電(dian)模(mo)型

    沙盤設置2個牽(qian)引變電所(suo)（1#、2#）、1個開閉所(suo)（主供車站(zhan)2#側(ce)線）、2個分區所(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(wei)機聯鎖(suo)及(ji)牽引(yin)供電系統操作臺

       系統(tong)實(shi)現牽引(yin)變電(dian)所(suo)、開閉所(suo)、分區所(suo)的計算機綜合控制功能。利(li)用計算機控制軟件(jian)實(shi)現對牽引(yin)供電(dian)的控制。真實(shi)再現牽引(yin)供電(dian)在不(bu)同運行方(fang)式和運行狀(zhuang)態下控制及(ji)操作功能，通過軟件(jian)界(jie)面實(shi)現真實(shi)供電(dian)系統(tong)的調度仿真。
