1、接觸網沙盤模型(xing)

      沙盤(pan)設(she)有1個(ge)(ge)既有鐵路(lu)(lu)中(zhong)(zhong)間站(zhan)、或N個(ge)(ge)既有線(xian)中(zhong)(zhong)間車(che)站(zhan)、雙線(xian)區間、綜合橋梁(liang)、隧道、涵洞，全整(zheng)的圓曲線(xian)、平交道口(kou)、設(she)典型(xing)道岔自(zi)(zi)動控(kong)制(zhi)；2個(ge)(ge)牽引(yin)變電(dian)(dian)所(suo)、2個(ge)(ge)分(fen)區亭、1個(ge)(ge)開(kai)閉所(suo)（內部結(jie)構清楚，原理準(zhun)確，通電(dian)(dian)演(yan)示(shi)）與(yu)1個(ge)(ge)AT所(suo)(靜態模型(xing))。既有線(xian)接(jie)觸(chu)網(wang)（可(ke)通電(dian)(dian)）采(cai)用(yong)半補償懸掛(gua)裝(zhuang)置與(yu)全補償懸掛(gua)裝(zhuang)置，四股(gu)道車(che)站(zhan)采(cai)用(yong)橫(heng)跨（兩(liang)個(ge)(ge)軟橫(heng)跨和(he)兩(liang)個(ge)(ge)硬橫(heng)跨）。線(xian)路(lu)(lu)上(shang)設(she)有分(fen)段(duan)絕(jue)緣器、錨(mao)段(duan)關節(jie)、中(zhong)(zhong)心(xin)錨(mao)節(jie)、饋(kui)電(dian)(dian)線(xian)、電(dian)(dian)連(lian)接(jie)器、回流線(xian)等(deng)設(she)備及各(ge)種線(xian)路(lu)(lu)、信號(hao)標志(zhi)并可(ke)通電(dian)(dian)演(yan)示(shi)及控(kong)制(zhi)，信號(hao)設(she)自(zi)(zi)動閉塞。接(jie)觸(chu)線(xian)、鋼軌均(jun)為(wei)銅制(zhi)。配遙(yao)控(kong)電(dian)(dian)力機(ji)車(che)兩(liang)臺運(yun)行。整(zheng)體形(xing)象逼真，結(jie)構清楚，制(zhi)作精(jing)美，采(cai)用(yong)計算機(ji)控(kong)制(zhi)系統 ，CRH2型(xing)動車(che)組從接(jie)觸(chu)網(wang)受電(dian)(dian)運(yun)行。

3、牽引(yin)變(bian)電模型

    沙盤設置2個(ge)牽引(yin)變電所（1#、2#）、1個(ge)開閉(bi)所（主供(gong)車站2#側線）、2個(ge)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(suo)及牽引(yin)供電系統操作臺(tai)

       系統(tong)實(shi)(shi)現牽(qian)引變電(dian)所(suo)(suo)、開閉所(suo)(suo)、分區(qu)所(suo)(suo)的計(ji)算機綜合控制功能。利用計(ji)算機控制軟件(jian)(jian)實(shi)(shi)現對牽(qian)引供(gong)電(dian)的控制。真實(shi)(shi)再(zai)現牽(qian)引供(gong)電(dian)在不同(tong)運行方式(shi)和運行狀(zhuang)態下控制及操作(zuo)功能，通過軟件(jian)(jian)界(jie)面實(shi)(shi)現真實(shi)(shi)供(gong)電(dian)系統(tong)的調度仿真。
