3、牽引變電模(mo)型

    沙盤設置2個牽引變電所(suo)（1#、2#）、1個開閉所(suo)（主供車(che)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(wei)機聯(lian)鎖及牽引供電系統操作臺

       系統實現(xian)牽引變電(dian)(dian)所(suo)、開閉(bi)所(suo)、分區所(suo)的計算(suan)機綜合控制功(gong)能(neng)(neng)。利用計算(suan)機控制軟件實現(xian)對牽引供(gong)電(dian)(dian)的控制。真實再(zai)現(xian)牽引供(gong)電(dian)(dian)在(zai)不同運(yun)行(xing)方式和(he)運(yun)行(xing)狀態下控制及操作(zuo)功(gong)能(neng)(neng)，通過軟件界面實現(xian)真實供(gong)電(dian)(dian)系統的調度(du)仿真。
