3、牽引(yin)變電(dian)模型

    沙盤設置2個(ge)牽(qian)引(yin)變電(dian)所（1#、2#）、1個(ge)開閉所（主(zhu)供車(che)站2#側線）、2個(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、微機聯鎖及牽引供電(dian)系統操作臺

       系統實現牽(qian)引變電所(suo)、開閉(bi)所(suo)、分區所(suo)的計算機(ji)(ji)綜(zong)合控(kong)制(zhi)功能(neng)。利用計算機(ji)(ji)控(kong)制(zhi)軟(ruan)(ruan)件實現對牽(qian)引供電的控(kong)制(zhi)。真實再現牽(qian)引供電在不同運(yun)行(xing)方(fang)式和(he)運(yun)行(xing)狀(zhuang)態下控(kong)制(zhi)及操(cao)作(zuo)功能(neng)，通過(guo)軟(ruan)(ruan)件界面實現真實供電系統的調度(du)仿真。
