1、接觸網(wang)沙(sha)盤模型

      沙盤設有(you)1個(ge)(ge)既(ji)有(you)鐵(tie)路中(zhong)間(jian)站、或N個(ge)(ge)既(ji)有(you)線(xian)(xian)中(zhong)間(jian)車站、雙線(xian)(xian)區間(jian)、綜合橋梁、隧道(dao)、涵洞，全(quan)整的圓(yuan)曲線(xian)(xian)、平交(jiao)道(dao)口(kou)、設典型(xing)道(dao)岔自動控(kong)制；2個(ge)(ge)牽(qian)引(yin)變電(dian)(dian)(dian)(dian)所、2個(ge)(ge)分(fen)區亭、1個(ge)(ge)開閉所（內部(bu)結(jie)(jie)構(gou)清(qing)(qing)楚，原理準確(que)，通(tong)(tong)電(dian)(dian)(dian)(dian)演示(shi)）與(yu)(yu)1個(ge)(ge)AT所(靜態模型(xing))。既(ji)有(you)線(xian)(xian)接(jie)(jie)觸(chu)網（可通(tong)(tong)電(dian)(dian)(dian)(dian)）采用(yong)半補(bu)償(chang)懸掛裝置與(yu)(yu)全(quan)補(bu)償(chang)懸掛裝置，四股(gu)道(dao)車站采用(yong)橫(heng)跨(kua)(kua)（兩(liang)個(ge)(ge)軟橫(heng)跨(kua)(kua)和兩(liang)個(ge)(ge)硬橫(heng)跨(kua)(kua)）。線(xian)(xian)路上設有(you)分(fen)段絕緣器、錨段關節、中(zhong)心錨節、饋電(dian)(dian)(dian)(dian)線(xian)(xian)、電(dian)(dian)(dian)(dian)連接(jie)(jie)器、回流線(xian)(xian)等設備及各種(zhong)線(xian)(xian)路、信(xin)號標志(zhi)并可通(tong)(tong)電(dian)(dian)(dian)(dian)演示(shi)及控(kong)制，信(xin)號設自動閉塞。接(jie)(jie)觸(chu)線(xian)(xian)、鋼軌均為銅制。配遙控(kong)電(dian)(dian)(dian)(dian)力機車兩(liang)臺運(yun)行。整體形象(xiang)逼(bi)真，結(jie)(jie)構(gou)清(qing)(qing)楚，制作(zuo)精美，采用(yong)計算機控(kong)制系統(tong) ，CRH2型(xing)動車組從接(jie)(jie)觸(chu)網受電(dian)(dian)(dian)(dian)運(yun)行。

2、車站軟,硬橫跨接觸(chu)網(wang)

3、牽引變(bian)電模(mo)型

    沙盤設置2個(ge)牽引變電(dian)所(suo)（1#、2#）、1個(ge)開(kai)閉所(suo)（主供車站2#側線）、2個(ge)分(fen)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、微機聯鎖及牽引供電(dian)系統操(cao)作臺(tai)

       系(xi)統實(shi)現(xian)(xian)(xian)牽(qian)引(yin)變電(dian)所(suo)、開閉所(suo)、分區所(suo)的計算機綜合控(kong)制功能。利用計算機控(kong)制軟件實(shi)現(xian)(xian)(xian)對(dui)牽(qian)引(yin)供電(dian)的控(kong)制。真實(shi)再(zai)現(xian)(xian)(xian)牽(qian)引(yin)供電(dian)在不(bu)同運行方式和運行狀(zhuang)態下控(kong)制及操(cao)作(zuo)功能，通過(guo)軟件界面實(shi)現(xian)(xian)(xian)真實(shi)供電(dian)系(xi)統的調(diao)度仿真。
