接(jie)觸網供電沙(sha)盤(pan)

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(bi)所（主供(gong)車站(zhan)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(qian)引供電系統操作臺

       系(xi)統實現(xian)牽(qian)引(yin)變電(dian)所、開(kai)閉(bi)所、分區所的計算(suan)機(ji)綜(zong)合控(kong)(kong)制功能。利(li)用計算(suan)機(ji)控(kong)(kong)制軟件(jian)實現(xian)對牽(qian)引(yin)供電(dian)的控(kong)(kong)制。真實再現(xian)牽(qian)引(yin)供電(dian)在不(bu)同(tong)運(yun)行方式(shi)和(he)運(yun)行狀態下控(kong)(kong)制及操作功能，通(tong)過軟件(jian)界面實現(xian)真實供電(dian)系(xi)統的調度(du)仿真。
