1、接觸網沙盤模型

      沙盤設有(you)(you)(you)1個(ge)既有(you)(you)(you)鐵路中(zhong)(zhong)間(jian)站、或(huo)N個(ge)既有(you)(you)(you)線(xian)(xian)(xian)(xian)中(zhong)(zhong)間(jian)車站、雙線(xian)(xian)(xian)(xian)區間(jian)、綜(zong)合橋梁、隧道、涵洞，全(quan)整的圓(yuan)曲線(xian)(xian)(xian)(xian)、平交道口、設典型道岔自(zi)動(dong)控制(zhi)(zhi)(zhi)；2個(ge)牽引變電(dian)(dian)所、2個(ge)分區亭、1個(ge)開閉所（內部(bu)結構(gou)清楚，原理準確(que)，通(tong)(tong)電(dian)(dian)演示(shi)）與(yu)1個(ge)AT所(靜態模型)。既有(you)(you)(you)線(xian)(xian)(xian)(xian)接(jie)觸(chu)(chu)網(wang)（可通(tong)(tong)電(dian)(dian)）采用(yong)半補償懸掛(gua)裝置與(yu)全(quan)補償懸掛(gua)裝置，四股(gu)道車站采用(yong)橫跨（兩個(ge)軟橫跨和(he)兩個(ge)硬橫跨）。線(xian)(xian)(xian)(xian)路上(shang)設有(you)(you)(you)分段絕緣器、錨段關節(jie)、中(zhong)(zhong)心錨節(jie)、饋電(dian)(dian)線(xian)(xian)(xian)(xian)、電(dian)(dian)連接(jie)器、回流(liu)線(xian)(xian)(xian)(xian)等設備及(ji)各(ge)種(zhong)線(xian)(xian)(xian)(xian)路、信號標(biao)志并可通(tong)(tong)電(dian)(dian)演示(shi)及(ji)控制(zhi)(zhi)(zhi)，信號設自(zi)動(dong)閉塞。接(jie)觸(chu)(chu)線(xian)(xian)(xian)(xian)、鋼軌均為銅制(zhi)(zhi)(zhi)。配(pei)遙控電(dian)(dian)力機車兩臺運行。整體形象逼真，結構(gou)清楚，制(zhi)(zhi)(zhi)作(zuo)精(jing)美，采用(yong)計算(suan)機控制(zhi)(zhi)(zhi)系統 ，CRH2型動(dong)車組從接(jie)觸(chu)(chu)網(wang)受電(dian)(dian)運行。

3、牽引(yin)變電模型(xing)

    沙盤設置2個牽引變(bian)電所(suo)(suo)（1#、2#）、1個開閉(bi)所(suo)(suo)（主供(gong)車站2#側線）、2個分區所(suo)(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、微機聯鎖及牽引供電(dian)系統操作臺

       系(xi)統實現(xian)(xian)(xian)牽(qian)引(yin)變電所(suo)(suo)、開閉所(suo)(suo)、分區所(suo)(suo)的(de)(de)計(ji)算機綜合控(kong)制(zhi)(zhi)功能。利用計(ji)算機控(kong)制(zhi)(zhi)軟(ruan)件(jian)實現(xian)(xian)(xian)對(dui)牽(qian)引(yin)供電的(de)(de)控(kong)制(zhi)(zhi)。真(zhen)(zhen)實再現(xian)(xian)(xian)牽(qian)引(yin)供電在不同(tong)運(yun)行(xing)方式和(he)運(yun)行(xing)狀態下控(kong)制(zhi)(zhi)及操(cao)作功能，通過軟(ruan)件(jian)界面實現(xian)(xian)(xian)真(zhen)(zhen)實供電系(xi)統的(de)(de)調度仿(fang)真(zhen)(zhen)。
