3、牽引變電模型(xing)

    沙盤設置2個牽引(yin)變電所(suo)（1#、2#）、1個開閉所(suo)（主供車站2#側(ce)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(suo)及牽引供電(dian)系統操作臺

       系統實現牽引(yin)(yin)變電(dian)所(suo)、開閉所(suo)、分區所(suo)的計(ji)算機(ji)(ji)綜合控(kong)(kong)制(zhi)功(gong)能。利用計(ji)算機(ji)(ji)控(kong)(kong)制(zhi)軟件實現對(dui)牽引(yin)(yin)供(gong)電(dian)的控(kong)(kong)制(zhi)。真(zhen)實再(zai)現牽引(yin)(yin)供(gong)電(dian)在不同運行方式和運行狀態下控(kong)(kong)制(zhi)及操作功(gong)能，通過軟件界(jie)面(mian)實現真(zhen)實供(gong)電(dian)系統的調度仿真(zhen)。
