3、牽引變電模型

    沙盤設置2個牽引變電(dian)所(suo)（1#、2#）、1個開閉所(suo)（主供車站2#側線）、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(suo)及牽引供電系統操作臺(tai)

       系統實(shi)現(xian)牽引(yin)變電所(suo)、開閉所(suo)、分區所(suo)的計(ji)(ji)算(suan)(suan)機(ji)綜合控(kong)(kong)制(zhi)(zhi)功能。利用計(ji)(ji)算(suan)(suan)機(ji)控(kong)(kong)制(zhi)(zhi)軟(ruan)件(jian)實(shi)現(xian)對牽引(yin)供電的控(kong)(kong)制(zhi)(zhi)。真實(shi)再現(xian)牽引(yin)供電在不同運行(xing)方式和運行(xing)狀態下控(kong)(kong)制(zhi)(zhi)及操(cao)作功能，通過軟(ruan)件(jian)界面實(shi)現(xian)真實(shi)供電系統的調度(du)仿真。
