1、接觸網沙盤模型

      沙盤設有(you)(you)1個既有(you)(you)鐵路(lu)中間站、或N個既有(you)(you)線(xian)中間車站、雙線(xian)區(qu)間、綜合橋梁、隧道(dao)、涵洞，全整的圓曲線(xian)、平交道(dao)口、設典(dian)型道(dao)岔(cha)自(zi)動(dong)控(kong)制(zhi)；2個牽引變電(dian)所、2個分(fen)區(qu)亭、1個開閉所（內部(bu)結(jie)構清楚(chu)，原理準確(que)，通(tong)電(dian)演示）與1個AT所(靜態模型)。既有(you)(you)線(xian)接觸(chu)網（可通(tong)電(dian)）采用半(ban)補(bu)(bu)償懸(xuan)掛(gua)裝置與全補(bu)(bu)償懸(xuan)掛(gua)裝置，四股道(dao)車站采用橫跨(kua)（兩(liang)(liang)個軟橫跨(kua)和兩(liang)(liang)個硬橫跨(kua)）。線(xian)路(lu)上(shang)設有(you)(you)分(fen)段(duan)絕緣器、錨段(duan)關節(jie)、中心錨節(jie)、饋(kui)電(dian)線(xian)、電(dian)連接器、回流線(xian)等設備及各種線(xian)路(lu)、信號標志(zhi)并可通(tong)電(dian)演示及控(kong)制(zhi)，信號設自(zi)動(dong)閉塞(sai)。接觸(chu)線(xian)、鋼軌均為(wei)銅制(zhi)。配(pei)遙控(kong)電(dian)力機車兩(liang)(liang)臺運行(xing)(xing)。整體(ti)形象(xiang)逼真，結(jie)構清楚(chu)，制(zhi)作精美，采用計算機控(kong)制(zhi)系統 ，CRH2型動(dong)車組從(cong)接觸(chu)網受電(dian)運行(xing)(xing)。

3、牽引(yin)變電模(mo)型

    沙盤設置2個牽引變電所(suo)（1#、2#）、1個開閉(bi)所(suo)（主供車站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、微機聯鎖(suo)及牽引(yin)供電系統操(cao)作臺

       系統實(shi)現(xian)(xian)牽(qian)引(yin)(yin)變電(dian)所、開閉所、分區(qu)所的(de)計算機綜合控(kong)(kong)制(zhi)功能。利用計算機控(kong)(kong)制(zhi)軟件實(shi)現(xian)(xian)對牽(qian)引(yin)(yin)供電(dian)的(de)控(kong)(kong)制(zhi)。真實(shi)再現(xian)(xian)牽(qian)引(yin)(yin)供電(dian)在不同(tong)運行(xing)方式和運行(xing)狀態下控(kong)(kong)制(zhi)及操作(zuo)功能，通過軟件界面實(shi)現(xian)(xian)真實(shi)供電(dian)系統的(de)調度(du)仿真。
