1、接觸網沙盤模型

      沙盤設(she)(she)有(you)(you)1個(ge)(ge)既(ji)有(you)(you)鐵路(lu)中間站、或N個(ge)(ge)既(ji)有(you)(you)線(xian)(xian)(xian)中間車站、雙線(xian)(xian)(xian)區間、綜(zong)合橋梁、隧道(dao)、涵洞，全整的圓(yuan)曲線(xian)(xian)(xian)、平交道(dao)口、設(she)(she)典型道(dao)岔自動(dong)控(kong)(kong)制(zhi)(zhi)；2個(ge)(ge)牽引變(bian)電(dian)所(suo)、2個(ge)(ge)分區亭(ting)、1個(ge)(ge)開閉(bi)所(suo)（內(nei)部結(jie)構(gou)清楚，原理準確，通電(dian)演示(shi)）與1個(ge)(ge)AT所(suo)(靜態模型)。既(ji)有(you)(you)線(xian)(xian)(xian)接觸網(wang)（可通電(dian)）采用半(ban)補償(chang)懸掛(gua)(gua)裝(zhuang)置(zhi)與全補償(chang)懸掛(gua)(gua)裝(zhuang)置(zhi)，四股(gu)道(dao)車站采用橫(heng)跨（兩個(ge)(ge)軟橫(heng)跨和兩個(ge)(ge)硬橫(heng)跨）。線(xian)(xian)(xian)路(lu)上(shang)設(she)(she)有(you)(you)分段(duan)絕緣器、錨段(duan)關節、中心錨節、饋電(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)、信號標志并可通電(dian)演示(shi)及控(kong)(kong)制(zhi)(zhi)，信號設(she)(she)自動(dong)閉(bi)塞。接觸線(xian)(xian)(xian)、鋼(gang)軌(gui)均為(wei)銅制(zhi)(zhi)。配遙控(kong)(kong)電(dian)力機車兩臺運(yun)行。整體形象逼真，結(jie)構(gou)清楚，制(zhi)(zhi)作精美(mei)，采用計(ji)算機控(kong)(kong)制(zhi)(zhi)系統 ，CRH2型動(dong)車組從接觸網(wang)受電(dian)運(yun)行。

3、牽引變電(dian)模型

    沙盤設置2個牽引變電所（1#、2#）、1個開閉所（主(zhu)供車站2#側(ce)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、微機聯鎖及牽引供電(dian)系統操作臺(tai)

       系統實現牽(qian)(qian)引變電所(suo)(suo)、開(kai)閉所(suo)(suo)、分(fen)區所(suo)(suo)的(de)計算機綜合(he)控制功(gong)能。利用(yong)計算機控制軟件(jian)實現對牽(qian)(qian)引供電的(de)控制。真實再現牽(qian)(qian)引供電在(zai)不同運行(xing)方式和運行(xing)狀(zhuang)態下控制及操作(zuo)功(gong)能，通過軟件(jian)界面(mian)實現真實供電系統的(de)調度仿真。
