3、牽引變電模型

    沙盤設置2個(ge)牽引變(bian)電(dian)所（1#、2#）、1個(ge)開閉(bi)所（主(zhu)供車站(zhan)2#側(ce)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(dian)系統操作臺

       系統實現(xian)牽引變電(dian)所(suo)、開(kai)閉所(suo)、分區所(suo)的計(ji)算(suan)機(ji)綜合控制(zhi)功能。利用計(ji)算(suan)機(ji)控制(zhi)軟件實現(xian)對牽引供電(dian)的控制(zhi)。真(zhen)實再現(xian)牽引供電(dian)在不(bu)同運行(xing)方式和運行(xing)狀態下控制(zhi)及操(cao)作(zuo)功能，通過軟件界面實現(xian)真(zhen)實供電(dian)系統的調度仿真(zhen)。
