3、牽引變電模(mo)型

    沙盤設置2個牽引(yin)變(bian)電(dian)所（1#、2#）、1個開閉所（主供車站2#側(ce)線）、2個分(fen)區(qu)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(wei)機聯鎖及(ji)牽引供電系統操作臺

       系統(tong)實(shi)(shi)現(xian)(xian)牽引變電(dian)所、開(kai)閉(bi)所、分區所的計(ji)算機綜合控(kong)(kong)制功能(neng)。利用計(ji)算機控(kong)(kong)制軟(ruan)件實(shi)(shi)現(xian)(xian)對牽引供(gong)(gong)電(dian)的控(kong)(kong)制。真(zhen)實(shi)(shi)再現(xian)(xian)牽引供(gong)(gong)電(dian)在不同運行(xing)方式和運行(xing)狀態(tai)下控(kong)(kong)制及(ji)操作功能(neng)，通過軟(ruan)件界(jie)面(mian)實(shi)(shi)現(xian)(xian)真(zhen)實(shi)(shi)供(gong)(gong)電(dian)系統(tong)的調度仿(fang)真(zhen)。
