3、牽引變電模型

    沙盤設置2個(ge)牽引變電所(suo)（1#、2#）、1個(ge)開閉所(suo)（主供車站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、微機聯鎖及牽引供電系統(tong)操(cao)作臺

       系(xi)統實(shi)現(xian)牽引(yin)變電所、開閉所、分區所的計(ji)算機綜合控(kong)制(zhi)(zhi)功能。利用計(ji)算機控(kong)制(zhi)(zhi)軟件(jian)實(shi)現(xian)對牽引(yin)供電的控(kong)制(zhi)(zhi)。真(zhen)實(shi)再(zai)現(xian)牽引(yin)供電在不同運(yun)行方式和運(yun)行狀態下控(kong)制(zhi)(zhi)及操(cao)作功能，通過軟件(jian)界面實(shi)現(xian)真(zhen)實(shi)供電系(xi)統的調度仿真(zhen)。
