1、接觸(chu)網(wang)沙盤模型

      沙盤設(she)(she)有1個既(ji)有鐵路(lu)中間站、或N個既(ji)有線(xian)中間車(che)(che)站、雙(shuang)線(xian)區間、綜合橋梁、隧道、涵(han)洞，全整的(de)圓(yuan)曲線(xian)、平交道口、設(she)(she)典(dian)型道岔(cha)自(zi)動(dong)控制(zhi)(zhi)；2個牽引變電(dian)(dian)所、2個分(fen)區亭(ting)、1個開閉所（內(nei)部結構清楚，原理準確(que)，通電(dian)(dian)演示）與1個AT所(靜態模(mo)型)。既(ji)有線(xian)接(jie)觸網（可通電(dian)(dian)）采用(yong)半(ban)補(bu)償懸(xuan)掛裝(zhuang)置與全補(bu)償懸(xuan)掛裝(zhuang)置，四股(gu)道車(che)(che)站采用(yong)橫(heng)(heng)跨（兩個軟橫(heng)(heng)跨和兩個硬(ying)橫(heng)(heng)跨）。線(xian)路(lu)上設(she)(she)有分(fen)段(duan)絕緣器、錨段(duan)關節、中心錨節、饋(kui)電(dian)(dian)線(xian)、電(dian)(dian)連接(jie)器、回流線(xian)等設(she)(she)備及各種(zhong)線(xian)路(lu)、信(xin)號標(biao)志并可通電(dian)(dian)演示及控制(zhi)(zhi)，信(xin)號設(she)(she)自(zi)動(dong)閉塞。接(jie)觸線(xian)、鋼軌均為銅制(zhi)(zhi)。配(pei)遙控電(dian)(dian)力機(ji)(ji)車(che)(che)兩臺運(yun)行。整體形象逼真，結構清楚，制(zhi)(zhi)作精美，采用(yong)計算(suan)機(ji)(ji)控制(zhi)(zhi)系統(tong) ，CRH2型動(dong)車(che)(che)組從接(jie)觸網受電(dian)(dian)運(yun)行。

3、牽引變電模型

    沙盤設置2個(ge)牽引變電所(suo)（1#、2#）、1個(ge)開閉所(suo)（主(zhu)供車站2#側線(xian)）、2個(ge)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、微機聯鎖及(ji)牽引供電(dian)系統操(cao)作(zuo)臺(tai)

       系統(tong)實(shi)現(xian)牽引變電(dian)(dian)所(suo)、開(kai)閉所(suo)、分區所(suo)的(de)計算機(ji)綜(zong)合控制(zhi)(zhi)功能。利(li)用計算機(ji)控制(zhi)(zhi)軟(ruan)件實(shi)現(xian)對牽引供(gong)電(dian)(dian)的(de)控制(zhi)(zhi)。真實(shi)再現(xian)牽引供(gong)電(dian)(dian)在不同運行(xing)方(fang)式和(he)運行(xing)狀態下控制(zhi)(zhi)及操作功能，通過軟(ruan)件界面實(shi)現(xian)真實(shi)供(gong)電(dian)(dian)系統(tong)的(de)調度(du)仿(fang)真。
