接(jie)觸網供電沙盤(pan)

3、牽引變電模型

    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、微機聯鎖及牽(qian)引供電(dian)系統(tong)操(cao)作臺

       系統實(shi)(shi)現(xian)(xian)牽引變電所(suo)(suo)、開閉(bi)所(suo)(suo)、分區所(suo)(suo)的(de)計算機綜合(he)控(kong)制功能。利用計算機控(kong)制軟(ruan)件實(shi)(shi)現(xian)(xian)對牽引供電的(de)控(kong)制。真實(shi)(shi)再現(xian)(xian)牽引供電在不同運(yun)行(xing)方式和(he)運(yun)行(xing)狀態下控(kong)制及(ji)操作功能，通過軟(ruan)件界(jie)面實(shi)(shi)現(xian)(xian)真實(shi)(shi)供電系統的(de)調度仿真。
