3、牽(qian)引變電模型

    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(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(dian)系統操作(zuo)臺

       系(xi)統實現牽引變電(dian)所、開閉所、分區(qu)所的計算(suan)機(ji)綜合(he)控制(zhi)功能。利用計算(suan)機(ji)控制(zhi)軟件(jian)實現對牽引供電(dian)的控制(zhi)。真實再(zai)現牽引供電(dian)在不同運(yun)行方式和運(yun)行狀態下控制(zhi)及操作功能，通(tong)過軟件(jian)界面實現真實供電(dian)系(xi)統的調度仿真。
