3、牽引變電模型(xing)

    沙盤設置2個(ge)(ge)牽引變電所（1#、2#）、1個(ge)(ge)開閉所（主供車站2#側(ce)線）、2個(ge)(ge)分(fen)區所；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(lian)鎖及(ji)牽引供電系統操作臺

       系(xi)統(tong)實現牽(qian)引(yin)變(bian)電(dian)(dian)所(suo)、開閉所(suo)、分區所(suo)的計算機(ji)綜合控(kong)制功能(neng)。利用(yong)計算機(ji)控(kong)制軟(ruan)件實現對牽(qian)引(yin)供電(dian)(dian)的控(kong)制。真(zhen)(zhen)實再現牽(qian)引(yin)供電(dian)(dian)在不同運行(xing)方式和運行(xing)狀態(tai)下控(kong)制及操作功能(neng)，通過(guo)軟(ruan)件界面實現真(zhen)(zhen)實供電(dian)(dian)系(xi)統(tong)的調度仿(fang)真(zhen)(zhen)。
