3、牽引變電模(mo)型

    沙盤設置2個牽引(yin)變電所（1#、2#）、1個開(kai)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(xi)統操(cao)作臺

       系統(tong)實(shi)(shi)現(xian)牽引(yin)變電所、開閉所、分區(qu)所的計算機(ji)綜合控(kong)制功能。利(li)用(yong)計算機(ji)控(kong)制軟件實(shi)(shi)現(xian)對牽引(yin)供(gong)電的控(kong)制。真(zhen)實(shi)(shi)再(zai)現(xian)牽引(yin)供(gong)電在不同運(yun)行(xing)方式(shi)和運(yun)行(xing)狀態下控(kong)制及操(cao)作功能，通過軟件界面實(shi)(shi)現(xian)真(zhen)實(shi)(shi)供(gong)電系統(tong)的調度仿(fang)真(zhen)。
