接(jie)觸(chu)網供電(dian)沙盤

3、牽引變電模型

    沙盤設置2個(ge)牽引變電(dian)所(suo)（1#、2#）、1個(ge)開閉所(suo)（主供車站2#側線）、2個(ge)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(ji)聯鎖及牽引供電(dian)系統(tong)操(cao)作臺

       系統(tong)實(shi)現(xian)牽(qian)引(yin)變電(dian)所(suo)、開閉所(suo)、分(fen)區(qu)所(suo)的計算(suan)機(ji)綜合控(kong)制功(gong)能(neng)。利用計算(suan)機(ji)控(kong)制軟件實(shi)現(xian)對牽(qian)引(yin)供電(dian)的控(kong)制。真(zhen)實(shi)再現(xian)牽(qian)引(yin)供電(dian)在不同運(yun)行方式和(he)運(yun)行狀態下控(kong)制及(ji)操作功(gong)能(neng)，通過軟件界面實(shi)現(xian)真(zhen)實(shi)供電(dian)系統(tong)的調度仿(fang)真(zhen)。
