1、接(jie)觸網沙盤模型

      沙盤設(she)有(you)1個(ge)既有(you)鐵(tie)路中(zhong)間站、或N個(ge)既有(you)線(xian)(xian)(xian)中(zhong)間車(che)站、雙線(xian)(xian)(xian)區(qu)間、綜合橋梁、隧道(dao)、涵洞，全整的圓曲(qu)線(xian)(xian)(xian)、平交(jiao)道(dao)口、設(she)典型道(dao)岔自動(dong)(dong)控制(zhi)；2個(ge)牽引變電(dian)所(suo)、2個(ge)分區(qu)亭、1個(ge)開閉(bi)所(suo)（內部結(jie)構(gou)清楚，原(yuan)理(li)準確(que)，通(tong)電(dian)演(yan)示）與1個(ge)AT所(suo)(靜態模型)。既有(you)線(xian)(xian)(xian)接(jie)(jie)觸網(wang)（可通(tong)電(dian)）采用半(ban)補(bu)(bu)償懸(xuan)掛(gua)裝置與全補(bu)(bu)償懸(xuan)掛(gua)裝置，四股(gu)道(dao)車(che)站采用橫跨(kua)（兩(liang)個(ge)軟橫跨(kua)和兩(liang)個(ge)硬橫跨(kua)）。線(xian)(xian)(xian)路上設(she)有(you)分段絕緣器(qi)、錨段關節(jie)、中(zhong)心錨節(jie)、饋電(dian)線(xian)(xian)(xian)、電(dian)連接(jie)(jie)器(qi)、回流線(xian)(xian)(xian)等設(she)備(bei)及各種線(xian)(xian)(xian)路、信號標志并(bing)可通(tong)電(dian)演(yan)示及控制(zhi)，信號設(she)自動(dong)(dong)閉(bi)塞(sai)。接(jie)(jie)觸線(xian)(xian)(xian)、鋼軌均為銅制(zhi)。配遙控電(dian)力機(ji)(ji)車(che)兩(liang)臺(tai)運行。整體形(xing)象逼(bi)真(zhen)，結(jie)構(gou)清楚，制(zhi)作精美，采用計算機(ji)(ji)控制(zhi)系統 ，CRH2型動(dong)(dong)車(che)組從(cong)接(jie)(jie)觸網(wang)受電(dian)運行。

3、牽引變電模型

    沙盤設置2個牽(qian)引變(bian)電所(suo)（1#、2#）、1個開閉所(suo)（主供車站2#側線）、2個分區所(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(wei)機聯(lian)鎖及牽引(yin)供電系統操作臺

       系統實(shi)現牽(qian)引(yin)變電(dian)(dian)所(suo)、開閉所(suo)、分區所(suo)的(de)計算機綜合控(kong)制功能(neng)。利(li)用計算機控(kong)制軟件(jian)實(shi)現對牽(qian)引(yin)供(gong)(gong)電(dian)(dian)的(de)控(kong)制。真(zhen)實(shi)再現牽(qian)引(yin)供(gong)(gong)電(dian)(dian)在不同(tong)運(yun)行方式和運(yun)行狀態(tai)下控(kong)制及操作功能(neng)，通過軟件(jian)界面實(shi)現真(zhen)實(shi)供(gong)(gong)電(dian)(dian)系統的(de)調度仿真(zhen)。
