3、牽(qian)引變電(dian)模型

    沙盤設置2個牽引變(bian)電(dian)所(suo)（1#、2#）、1個開閉所(suo)（主(zhu)供車(che)站2#側(ce)線(xian)）、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、微機聯鎖及牽引供電系統操(cao)作(zuo)臺

       系(xi)統實(shi)現牽(qian)引變電(dian)所、開(kai)閉所、分區所的(de)計(ji)(ji)算(suan)機綜合(he)控(kong)制功能。利用計(ji)(ji)算(suan)機控(kong)制軟(ruan)件實(shi)現對牽(qian)引供(gong)電(dian)的(de)控(kong)制。真實(shi)再現牽(qian)引供(gong)電(dian)在(zai)不同運行方式和運行狀(zhuang)態下控(kong)制及操作功能，通過軟(ruan)件界面實(shi)現真實(shi)供(gong)電(dian)系(xi)統的(de)調度仿(fang)真。
