3、牽引變電模型

    沙盤設置2個(ge)牽引(yin)變電(dian)所(suo)(suo)（1#、2#）、1個(ge)開閉所(suo)(suo)（主供車站2#側線）、2個(ge)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(wei)機聯鎖及牽(qian)引供電系統(tong)操作(zuo)臺

       系統實(shi)(shi)現(xian)牽(qian)(qian)引變電所、開(kai)閉所、分區所的(de)計算機(ji)綜合(he)控制(zhi)(zhi)功(gong)能(neng)。利用計算機(ji)控制(zhi)(zhi)軟件實(shi)(shi)現(xian)對牽(qian)(qian)引供電的(de)控制(zhi)(zhi)。真實(shi)(shi)再現(xian)牽(qian)(qian)引供電在(zai)不同運(yun)行(xing)方式和運(yun)行(xing)狀態下控制(zhi)(zhi)及操作功(gong)能(neng)，通過軟件界面實(shi)(shi)現(xian)真實(shi)(shi)供電系統的(de)調(diao)度仿(fang)真。
