1、接觸(chu)網沙(sha)盤模型

      沙盤設(she)有(you)(you)(you)1個(ge)(ge)既有(you)(you)(you)鐵(tie)路(lu)中(zhong)間(jian)站(zhan)、或N個(ge)(ge)既有(you)(you)(you)線(xian)(xian)(xian)中(zhong)間(jian)車站(zhan)、雙線(xian)(xian)(xian)區間(jian)、綜(zong)合橋梁(liang)、隧道(dao)、涵洞，全整的圓曲線(xian)(xian)(xian)、平交(jiao)道(dao)口、設(she)典型道(dao)岔自動(dong)控(kong)(kong)制；2個(ge)(ge)牽引變電(dian)所(suo)、2個(ge)(ge)分(fen)區亭、1個(ge)(ge)開閉(bi)所(suo)（內部結構清楚(chu)，原理準確，通電(dian)演(yan)示(shi)）與(yu)1個(ge)(ge)AT所(suo)(靜態模型)。既有(you)(you)(you)線(xian)(xian)(xian)接(jie)觸網（可(ke)通電(dian)）采用半補償(chang)懸掛(gua)裝(zhuang)置與(yu)全補償(chang)懸掛(gua)裝(zhuang)置，四股道(dao)車站(zhan)采用橫(heng)跨（兩(liang)個(ge)(ge)軟橫(heng)跨和兩(liang)個(ge)(ge)硬橫(heng)跨）。線(xian)(xian)(xian)路(lu)上設(she)有(you)(you)(you)分(fen)段絕(jue)緣(yuan)器、錨段關節、中(zhong)心錨節、饋電(dian)線(xian)(xian)(xian)、電(dian)連接(jie)器、回流線(xian)(xian)(xian)等設(she)備(bei)及(ji)各種線(xian)(xian)(xian)路(lu)、信(xin)號標志(zhi)并可(ke)通電(dian)演(yan)示(shi)及(ji)控(kong)(kong)制，信(xin)號設(she)自動(dong)閉(bi)塞。接(jie)觸線(xian)(xian)(xian)、鋼(gang)軌(gui)均為(wei)銅(tong)制。配遙(yao)控(kong)(kong)電(dian)力機(ji)車兩(liang)臺運(yun)行。整體(ti)形(xing)象逼真，結構清楚(chu)，制作(zuo)精(jing)美，采用計算(suan)機(ji)控(kong)(kong)制系統 ，CRH2型動(dong)車組(zu)從接(jie)觸網受(shou)電(dian)運(yun)行。

接(jie)觸網(wang)供(gong)電沙盤

3、牽(qian)引變電模(mo)型

    沙盤設置2個牽(qian)引變電所（1#、2#）、1個開閉所（主供車站2#側(ce)線）、2個分區(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)機聯鎖及牽引供電系統(tong)操作臺

       系統(tong)實現牽(qian)(qian)引(yin)變(bian)電(dian)所、開(kai)閉所、分區所的計算機綜合控(kong)制(zhi)(zhi)功(gong)(gong)能(neng)。利用計算機控(kong)制(zhi)(zhi)軟件實現對牽(qian)(qian)引(yin)供(gong)電(dian)的控(kong)制(zhi)(zhi)。真(zhen)實再現牽(qian)(qian)引(yin)供(gong)電(dian)在(zai)不(bu)同運行方式和運行狀態(tai)下控(kong)制(zhi)(zhi)及操作功(gong)(gong)能(neng)，通過軟件界面實現真(zhen)實供(gong)電(dian)系統(tong)的調(diao)度仿(fang)真(zhen)。
