3、牽引變電模型

    沙盤設置2個牽引變電(dian)所(suo)（1#、2#）、1個開(kai)閉所(suo)（主供(gong)車站(zhan)2#側(ce)線(xian)）、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系統操作臺

       系統實(shi)現牽(qian)引變電(dian)所(suo)(suo)(suo)、開閉所(suo)(suo)(suo)、分區所(suo)(suo)(suo)的計算機綜合控制(zhi)功(gong)能(neng)。利用計算機控制(zhi)軟件實(shi)現對牽(qian)引供電(dian)的控制(zhi)。真(zhen)實(shi)再現牽(qian)引供電(dian)在不同運行方式和(he)運行狀態下(xia)控制(zhi)及操作(zuo)功(gong)能(neng)，通過軟件界面(mian)實(shi)現真(zhen)實(shi)供電(dian)系統的調度仿(fang)真(zhen)。
