3、牽(qian)引變(bian)電模(mo)型

    沙盤設置2個(ge)牽(qian)引變電所（1#、2#）、1個(ge)開閉所（主供車(che)站2#側線）、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、微機聯鎖及牽引供電系統操(cao)作臺

       系統(tong)實現(xian)牽(qian)引變(bian)電所、開閉所、分區所的計(ji)算(suan)機(ji)綜合控制(zhi)功能。利(li)用計(ji)算(suan)機(ji)控制(zhi)軟件(jian)實現(xian)對牽(qian)引供電的控制(zhi)。真(zhen)實再(zai)現(xian)牽(qian)引供電在不同運行方式和(he)運行狀態下控制(zhi)及操(cao)作功能，通過(guo)軟件(jian)界(jie)面實現(xian)真(zhen)實供電系統(tong)的調(diao)度(du)仿真(zhen)。
