3、牽引(yin)變電模型

    沙盤設置2個牽(qian)引變電(dian)所（1#、2#）、1個開閉(bi)所（主供車站2#側(ce)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)操作(zuo)臺

       系統(tong)實(shi)現(xian)牽引變(bian)電所(suo)、開閉所(suo)、分區(qu)所(suo)的計算(suan)機綜合控(kong)制(zhi)功能。利用計算(suan)機控(kong)制(zhi)軟(ruan)件(jian)實(shi)現(xian)對(dui)牽引供電的控(kong)制(zhi)。真(zhen)實(shi)再現(xian)牽引供電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(ruan)件(jian)界面實(shi)現(xian)真(zhen)實(shi)供電系統(tong)的調度仿真(zhen)。
