1、接觸(chu)網沙盤模型

      沙盤設有(you)1個(ge)既(ji)有(you)鐵路中(zhong)間(jian)站(zhan)、或N個(ge)既(ji)有(you)線中(zhong)間(jian)車站(zhan)、雙線區間(jian)、綜(zong)合橋梁(liang)、隧道、涵洞，全整(zheng)的圓曲線、平交道口、設典型(xing)道岔自動控(kong)制(zhi)；2個(ge)牽引變電(dian)(dian)(dian)(dian)所(suo)、2個(ge)分區亭、1個(ge)開閉所(suo)（內(nei)部結構(gou)清楚(chu)(chu)，原理準確，通電(dian)(dian)(dian)(dian)演(yan)示）與(yu)1個(ge)AT所(suo)(靜態模(mo)型(xing))。既(ji)有(you)線接(jie)觸(chu)網（可通電(dian)(dian)(dian)(dian)）采(cai)(cai)用(yong)半補(bu)償懸(xuan)掛(gua)裝置與(yu)全補(bu)償懸(xuan)掛(gua)裝置，四股道車站(zhan)采(cai)(cai)用(yong)橫(heng)跨（兩個(ge)軟(ruan)橫(heng)跨和兩個(ge)硬橫(heng)跨）。線路上設有(you)分段絕緣器、錨段關節、中(zhong)心錨節、饋(kui)電(dian)(dian)(dian)(dian)線、電(dian)(dian)(dian)(dian)連接(jie)器、回流線等設備及各種(zhong)線路、信號標(biao)志并可通電(dian)(dian)(dian)(dian)演(yan)示及控(kong)制(zhi)，信號設自動閉塞。接(jie)觸(chu)線、鋼軌均(jun)為銅制(zhi)。配遙控(kong)電(dian)(dian)(dian)(dian)力機(ji)車兩臺運(yun)(yun)行。整(zheng)體形(xing)象逼真，結構(gou)清楚(chu)(chu)，制(zhi)作精美，采(cai)(cai)用(yong)計算(suan)機(ji)控(kong)制(zhi)系統 ，CRH2型(xing)動車組從接(jie)觸(chu)網受電(dian)(dian)(dian)(dian)運(yun)(yun)行。

3、牽引變電模型(xing)

    沙盤設置2個牽引變(bian)電(dian)所（1#、2#）、1個開閉所（主供車(che)站2#側線(xian)）、2個分區所；采用彩色有機玻璃雕刻技術，來模擬牽引變電所的房屋。

4、微機(ji)聯鎖及牽引(yin)供電系統操作臺

       系統實現牽(qian)引(yin)變電(dian)(dian)(dian)所、開(kai)閉(bi)所、分區(qu)所的計(ji)算機綜(zong)合控(kong)(kong)制(zhi)(zhi)(zhi)功能。利用(yong)計(ji)算機控(kong)(kong)制(zhi)(zhi)(zhi)軟件實現對牽(qian)引(yin)供(gong)電(dian)(dian)(dian)的控(kong)(kong)制(zhi)(zhi)(zhi)。真(zhen)(zhen)實再現牽(qian)引(yin)供(gong)電(dian)(dian)(dian)在不同運行方式(shi)和(he)運行狀態下(xia)控(kong)(kong)制(zhi)(zhi)(zhi)及操作功能，通過(guo)軟件界面實現真(zhen)(zhen)實供(gong)電(dian)(dian)(dian)系統的調(diao)度仿(fang)真(zhen)(zhen)。
