3、牽引變電(dian)模(mo)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、微機聯鎖及牽引供(gong)電系統操作臺

       系(xi)(xi)統(tong)實(shi)現(xian)牽引變電(dian)(dian)所(suo)(suo)(suo)、開(kai)閉所(suo)(suo)(suo)、分區所(suo)(suo)(suo)的計(ji)算(suan)機綜(zong)合控制(zhi)(zhi)功能。利用計(ji)算(suan)機控制(zhi)(zhi)軟件實(shi)現(xian)對牽引供(gong)電(dian)(dian)的控制(zhi)(zhi)。真實(shi)再現(xian)牽引供(gong)電(dian)(dian)在不同運行(xing)方式和(he)運行(xing)狀態下控制(zhi)(zhi)及操作功能，通過軟件界面實(shi)現(xian)真實(shi)供(gong)電(dian)(dian)系(xi)(xi)統(tong)的調度仿(fang)真。
