3、牽引變電(dian)模型

    沙盤設置2個牽引變(bian)電所(suo)（1#、2#）、1個開閉所(suo)（主(zhu)供車站2#側線）、2個分區所(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、微機聯鎖及牽引供電系統操作臺

       系統實現牽(qian)引變電所、開閉(bi)所、分區所的(de)計(ji)算機綜合控(kong)制功(gong)(gong)能。利(li)用計(ji)算機控(kong)制軟件實現對牽(qian)引供電的(de)控(kong)制。真實再現牽(qian)引供電在不同運(yun)行方式和(he)運(yun)行狀態下(xia)控(kong)制及操作功(gong)(gong)能，通過軟件界面實現真實供電系統的(de)調(diao)度仿真。
