1、接(jie)觸網(wang)沙盤模(mo)型

      沙盤設(she)(she)有1個既有鐵(tie)路(lu)中(zhong)(zhong)間站、或N個既有線(xian)(xian)(xian)(xian)(xian)中(zhong)(zhong)間車站、雙線(xian)(xian)(xian)(xian)(xian)區(qu)間、綜(zong)合(he)橋梁、隧(sui)道(dao)(dao)、涵洞，全(quan)(quan)整(zheng)的圓(yuan)曲(qu)線(xian)(xian)(xian)(xian)(xian)、平交道(dao)(dao)口、設(she)(she)典(dian)型道(dao)(dao)岔自動控(kong)制(zhi)(zhi)；2個牽引變電(dian)所、2個分(fen)區(qu)亭、1個開閉(bi)(bi)所（內部(bu)結構清楚，原理準(zhun)確，通(tong)電(dian)演示）與1個AT所(靜態(tai)模型)。既有線(xian)(xian)(xian)(xian)(xian)接(jie)觸網（可通(tong)電(dian)）采(cai)(cai)用(yong)(yong)半補(bu)償(chang)懸掛(gua)裝(zhuang)置(zhi)與全(quan)(quan)補(bu)償(chang)懸掛(gua)裝(zhuang)置(zhi)，四股道(dao)(dao)車站采(cai)(cai)用(yong)(yong)橫跨（兩(liang)(liang)個軟橫跨和(he)兩(liang)(liang)個硬(ying)橫跨）。線(xian)(xian)(xian)(xian)(xian)路(lu)上設(she)(she)有分(fen)段絕緣器、錨段關節、中(zhong)(zhong)心錨節、饋(kui)電(dian)線(xian)(xian)(xian)(xian)(xian)、電(dian)連(lian)接(jie)器、回流線(xian)(xian)(xian)(xian)(xian)等設(she)(she)備(bei)及各種線(xian)(xian)(xian)(xian)(xian)路(lu)、信號標志并(bing)可通(tong)電(dian)演示及控(kong)制(zhi)(zhi)，信號設(she)(she)自動閉(bi)(bi)塞。接(jie)觸線(xian)(xian)(xian)(xian)(xian)、鋼(gang)軌均為銅(tong)制(zhi)(zhi)。配(pei)遙控(kong)電(dian)力機車兩(liang)(liang)臺運行。整(zheng)體(ti)形(xing)象逼真(zhen)，結構清楚，制(zhi)(zhi)作精美，采(cai)(cai)用(yong)(yong)計(ji)算機控(kong)制(zhi)(zhi)系統 ，CRH2型動車組(zu)從接(jie)觸網受電(dian)運行。

3、牽引變電模型(xing)

    沙盤設置2個(ge)牽(qian)引變(bian)電所(suo)（1#、2#）、1個(ge)開閉所(suo)（主供車站(zhan)2#側線）、2個(ge)分區(qu)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(suo)及牽引供電系統操作臺

       系統(tong)實(shi)(shi)現(xian)牽引變電(dian)所、開(kai)閉所、分區(qu)所的(de)計算機綜合控制功能。利用計算機控制軟件(jian)實(shi)(shi)現(xian)對牽引供電(dian)的(de)控制。真實(shi)(shi)再現(xian)牽引供電(dian)在(zai)不同(tong)運(yun)行方(fang)式(shi)和運(yun)行狀態(tai)下控制及(ji)操作功能，通過軟件(jian)界面(mian)實(shi)(shi)現(xian)真實(shi)(shi)供電(dian)系統(tong)的(de)調度(du)仿真。
