3、牽引變(bian)電(dian)模型

    沙盤設置2個(ge)牽引變電所(suo)（1#、2#）、1個(ge)開閉所(suo)（主供車站2#側線）、2個(ge)分(fen)區(qu)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(lian)鎖及牽引(yin)供(gong)電系統操作臺(tai)

       系(xi)統實現(xian)(xian)牽引變電(dian)(dian)所、開(kai)閉(bi)所、分區(qu)所的計算(suan)機(ji)綜合控制(zhi)功能。利用(yong)計算(suan)機(ji)控制(zhi)軟(ruan)件(jian)實現(xian)(xian)對(dui)牽引供(gong)電(dian)(dian)的控制(zhi)。真(zhen)實再(zai)現(xian)(xian)牽引供(gong)電(dian)(dian)在不同運(yun)行方(fang)式和運(yun)行狀態下控制(zhi)及操作功能，通過軟(ruan)件(jian)界面實現(xian)(xian)真(zhen)實供(gong)電(dian)(dian)系(xi)統的調度仿真(zhen)。
