1、接觸網沙(sha)盤模(mo)型

      沙盤設(she)有(you)1個(ge)(ge)既(ji)(ji)有(you)鐵路(lu)(lu)中(zhong)(zhong)間(jian)站、或N個(ge)(ge)既(ji)(ji)有(you)線(xian)中(zhong)(zhong)間(jian)車(che)(che)(che)站、雙線(xian)區間(jian)、綜合橋(qiao)梁、隧道、涵洞(dong)，全(quan)整(zheng)的圓曲(qu)線(xian)、平交道口(kou)、設(she)典(dian)型道岔自(zi)動控(kong)(kong)(kong)制(zhi)(zhi)；2個(ge)(ge)牽引(yin)變電(dian)(dian)所、2個(ge)(ge)分區亭、1個(ge)(ge)開閉所（內部結(jie)(jie)構(gou)清楚，原理準確，通電(dian)(dian)演示(shi)）與1個(ge)(ge)AT所(靜態模(mo)型)。既(ji)(ji)有(you)線(xian)接(jie)觸網(wang)（可(ke)(ke)通電(dian)(dian)）采用(yong)半補(bu)償懸(xuan)掛(gua)裝置與全(quan)補(bu)償懸(xuan)掛(gua)裝置，四股道車(che)(che)(che)站采用(yong)橫(heng)跨（兩個(ge)(ge)軟橫(heng)跨和兩個(ge)(ge)硬橫(heng)跨）。線(xian)路(lu)(lu)上設(she)有(you)分段絕緣器、錨(mao)段關節、中(zhong)(zhong)心錨(mao)節、饋電(dian)(dian)線(xian)、電(dian)(dian)連接(jie)器、回(hui)流線(xian)等設(she)備及(ji)(ji)各種(zhong)線(xian)路(lu)(lu)、信號標志并可(ke)(ke)通電(dian)(dian)演示(shi)及(ji)(ji)控(kong)(kong)(kong)制(zhi)(zhi)，信號設(she)自(zi)動閉塞。接(jie)觸線(xian)、鋼軌均為(wei)銅制(zhi)(zhi)。配遙控(kong)(kong)(kong)電(dian)(dian)力機(ji)車(che)(che)(che)兩臺運(yun)行。整(zheng)體形象(xiang)逼(bi)真，結(jie)(jie)構(gou)清楚，制(zhi)(zhi)作(zuo)精美，采用(yong)計算(suan)機(ji)控(kong)(kong)(kong)制(zhi)(zhi)系統(tong) ，CRH2型動車(che)(che)(che)組從(cong)接(jie)觸網(wang)受電(dian)(dian)運(yun)行。

2、車站軟(ruan),硬橫跨接觸(chu)網

接觸(chu)網供(gong)電(dian)沙盤

3、牽引變電模(mo)型

    沙盤設置2個牽引變電所（1#、2#）、1個開(kai)閉所（主供車站2#側線(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(qian)引供電系(xi)統操(cao)作臺(tai)

       系(xi)統實現(xian)牽(qian)(qian)引(yin)變電(dian)所、開閉(bi)所、分區所的(de)計算機綜合(he)控制功能(neng)。利用(yong)計算機控制軟件實現(xian)對牽(qian)(qian)引(yin)供電(dian)的(de)控制。真(zhen)實再現(xian)牽(qian)(qian)引(yin)供電(dian)在不同(tong)運行(xing)方式(shi)和運行(xing)狀態下(xia)控制及操作(zuo)功能(neng)，通過軟件界(jie)面(mian)實現(xian)真(zhen)實供電(dian)系(xi)統的(de)調度仿真(zhen)。
