3、牽引變電模型

    沙盤設置2個(ge)(ge)牽引變(bian)電所(suo)（1#、2#）、1個(ge)(ge)開(kai)閉所(suo)（主供(gong)車站2#側(ce)線(xian)）、2個(ge)(ge)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(yin)供電系統操作臺

       系統(tong)(tong)實現(xian)(xian)牽(qian)引變電(dian)(dian)所、開閉所、分區所的(de)計(ji)算機綜合控(kong)制功能(neng)。利(li)用計(ji)算機控(kong)制軟(ruan)(ruan)件實現(xian)(xian)對牽(qian)引供(gong)電(dian)(dian)的(de)控(kong)制。真實再現(xian)(xian)牽(qian)引供(gong)電(dian)(dian)在不同運行方(fang)式(shi)和運行狀(zhuang)態下控(kong)制及(ji)操作(zuo)功能(neng)，通過(guo)軟(ruan)(ruan)件界(jie)面實現(xian)(xian)真實供(gong)電(dian)(dian)系統(tong)(tong)的(de)調(diao)度仿真。
