3、牽引變電模型(xing)

    沙盤設置2個牽引變電所(suo)（1#、2#）、1個開閉所(suo)（主供(gong)車站2#側(ce)線）、2個分區所(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(dian)系統操作臺

       系(xi)(xi)統實(shi)現(xian)牽引變電(dian)(dian)所、開閉所、分區(qu)所的計算機綜合(he)控(kong)制(zhi)功能。利用計算機控(kong)制(zhi)軟件實(shi)現(xian)對牽引供(gong)電(dian)(dian)的控(kong)制(zhi)。真實(shi)再現(xian)牽引供(gong)電(dian)(dian)在不同運行方式和運行狀態下控(kong)制(zhi)及操作功能，通過軟件界面(mian)實(shi)現(xian)真實(shi)供(gong)電(dian)(dian)系(xi)(xi)統的調度仿真。
