3、牽引變電模型

    沙盤設置2個牽引變電所(suo)（1#、2#）、1個開閉所(suo)（主供車站2#側(ce)線）、2個分區(qu)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(ji)聯鎖及牽引供電(dian)系統操(cao)作(zuo)臺

       系(xi)統(tong)實(shi)(shi)現牽(qian)引變電(dian)所(suo)、開閉(bi)所(suo)、分(fen)區(qu)所(suo)的計算機(ji)綜合(he)控(kong)(kong)制功(gong)能。利(li)用計算機(ji)控(kong)(kong)制軟件(jian)(jian)實(shi)(shi)現對牽(qian)引供電(dian)的控(kong)(kong)制。真(zhen)實(shi)(shi)再現牽(qian)引供電(dian)在不同運(yun)行方式(shi)和運(yun)行狀態下控(kong)(kong)制及操作功(gong)能，通過軟件(jian)(jian)界面實(shi)(shi)現真(zhen)實(shi)(shi)供電(dian)系(xi)統(tong)的調度(du)仿真(zhen)。
