3、牽(qian)引變電(dian)模型

    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(lian)鎖及牽引供電系統操作臺

       系統(tong)實現(xian)牽引(yin)變電所(suo)、開閉所(suo)、分區所(suo)的(de)計算(suan)機(ji)綜合控(kong)制功(gong)能。利(li)用計算(suan)機(ji)控(kong)制軟(ruan)件實現(xian)對牽引(yin)供電的(de)控(kong)制。真實再(zai)現(xian)牽引(yin)供電在(zai)不同運(yun)行(xing)方式和(he)運(yun)行(xing)狀態下控(kong)制及操作功(gong)能，通過軟(ruan)件界面實現(xian)真實供電系統(tong)的(de)調度(du)仿真。
