3、牽引變電模型(xing)

    沙盤設置2個(ge)牽引變電所（1#、2#）、1個(ge)開閉所（主供車站2#側(ce)線(xian)）、2個(ge)分區(qu)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(wei)機聯鎖(suo)及牽引供電系(xi)統操作臺

       系統(tong)實現牽(qian)引變電所(suo)(suo)、開(kai)閉所(suo)(suo)、分區所(suo)(suo)的計算機綜(zong)合控(kong)(kong)制功能。利用(yong)計算機控(kong)(kong)制軟件(jian)實現對牽(qian)引供(gong)電的控(kong)(kong)制。真(zhen)實再現牽(qian)引供(gong)電在(zai)不同運(yun)行方式和運(yun)行狀態下控(kong)(kong)制及操作(zuo)功能，通(tong)過軟件(jian)界面實現真(zhen)實供(gong)電系統(tong)的調(diao)度仿真(zhen)。
