3、牽引變電模型(xing)

    沙盤設置2個(ge)牽引(yin)變電(dian)所（1#、2#）、1個(ge)開(kai)閉(bi)所（主供車(che)站2#側線(xian)）、2個(ge)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(ji)聯鎖及牽引供電系統操作臺

       系(xi)(xi)統實現(xian)(xian)牽(qian)引變電(dian)所(suo)、開閉所(suo)、分區所(suo)的計(ji)算(suan)機綜合控制(zhi)(zhi)(zhi)功能。利用計(ji)算(suan)機控制(zhi)(zhi)(zhi)軟(ruan)件(jian)實現(xian)(xian)對牽(qian)引供(gong)電(dian)的控制(zhi)(zhi)(zhi)。真實再(zai)現(xian)(xian)牽(qian)引供(gong)電(dian)在不(bu)同運(yun)行(xing)方(fang)式和運(yun)行(xing)狀態下控制(zhi)(zhi)(zhi)及操作功能，通過軟(ruan)件(jian)界面實現(xian)(xian)真實供(gong)電(dian)系(xi)(xi)統的調(diao)度仿真。
