3、牽引(yin)變電模型(xing)

    沙盤設置2個(ge)牽引變電(dian)所(suo)（1#、2#）、1個(ge)開閉所(suo)（主供車站2#側線）、2個(ge)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、微機聯鎖及牽引供電系統操(cao)作(zuo)臺

       系統(tong)實(shi)現(xian)牽引變電(dian)(dian)所、開閉(bi)所、分區所的(de)計算(suan)機綜合控(kong)制(zhi)功能。利(li)用計算(suan)機控(kong)制(zhi)軟件(jian)實(shi)現(xian)對牽引供(gong)電(dian)(dian)的(de)控(kong)制(zhi)。真實(shi)再現(xian)牽引供(gong)電(dian)(dian)在不同運行方式和運行狀態(tai)下控(kong)制(zhi)及操作(zuo)功能，通過軟件(jian)界面(mian)實(shi)現(xian)真實(shi)供(gong)電(dian)(dian)系統(tong)的(de)調(diao)度仿真。
