1、接(jie)觸網沙盤(pan)模型

      沙盤(pan)設(she)(she)有(you)1個(ge)(ge)既有(you)鐵路(lu)中間站、或N個(ge)(ge)既有(you)線(xian)(xian)(xian)中間車站、雙線(xian)(xian)(xian)區(qu)間、綜合橋梁(liang)、隧道(dao)(dao)(dao)、涵(han)洞，全(quan)整的(de)圓曲線(xian)(xian)(xian)、平交(jiao)道(dao)(dao)(dao)口、設(she)(she)典(dian)型道(dao)(dao)(dao)岔自動控(kong)(kong)制(zhi)(zhi)；2個(ge)(ge)牽(qian)引變電(dian)所(suo)、2個(ge)(ge)分(fen)區(qu)亭、1個(ge)(ge)開閉(bi)所(suo)（內部結(jie)構清(qing)楚，原理(li)準確，通電(dian)演示）與1個(ge)(ge)AT所(suo)(靜態(tai)模型)。既有(you)線(xian)(xian)(xian)接觸(chu)網（可通電(dian)）采用(yong)半補償懸掛裝置與全(quan)補償懸掛裝置，四股(gu)道(dao)(dao)(dao)車站采用(yong)橫(heng)跨（兩(liang)(liang)(liang)個(ge)(ge)軟橫(heng)跨和兩(liang)(liang)(liang)個(ge)(ge)硬橫(heng)跨）。線(xian)(xian)(xian)路(lu)上設(she)(she)有(you)分(fen)段絕緣器、錨(mao)段關節、中心錨(mao)節、饋(kui)電(dian)線(xian)(xian)(xian)、電(dian)連(lian)接器、回流線(xian)(xian)(xian)等設(she)(she)備及各(ge)種(zhong)線(xian)(xian)(xian)路(lu)、信(xin)號標志并可通電(dian)演示及控(kong)(kong)制(zhi)(zhi)，信(xin)號設(she)(she)自動閉(bi)塞。接觸(chu)線(xian)(xian)(xian)、鋼軌均為銅(tong)制(zhi)(zhi)。配(pei)遙控(kong)(kong)電(dian)力機(ji)車兩(liang)(liang)(liang)臺運行。整體形(xing)象逼(bi)真(zhen)，結(jie)構清(qing)楚，制(zhi)(zhi)作精美，采用(yong)計算機(ji)控(kong)(kong)制(zhi)(zhi)系統 ，CRH2型動車組從(cong)接觸(chu)網受電(dian)運行。

3、牽引變電模型

    沙盤設置2個牽(qian)引變電(dian)所（1#、2#）、1個開閉(bi)所（主(zhu)供車(che)站2#側線）、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、微機聯鎖及牽(qian)引(yin)供電系(xi)統(tong)操作臺

       系統(tong)實(shi)現(xian)(xian)(xian)牽引變電所、開閉所、分區(qu)所的計(ji)算機綜合控(kong)制功能(neng)。利用計(ji)算機控(kong)制軟件實(shi)現(xian)(xian)(xian)對(dui)牽引供電的控(kong)制。真實(shi)再現(xian)(xian)(xian)牽引供電在(zai)不(bu)同運(yun)行(xing)(xing)方式和運(yun)行(xing)(xing)狀態下控(kong)制及操作功能(neng)，通過軟件界(jie)面實(shi)現(xian)(xian)(xian)真實(shi)供電系統(tong)的調(diao)度仿(fang)真。
