接觸網及牽引供電沙盤

     全面分(fen)析我國當前電(dian)(dian)氣化鐵道牽(qian)引供(gong)電(dian)(dian)技術(shu)、接觸網特點和(he)安全操(cao)作規程的(de)(de)(de)(de)基礎上，通過計算機仿真模(mo)擬電(dian)(dian)氣化鐵道牽(qian)引供(gong)電(dian)(dian)所涉及(ji)的(de)(de)(de)(de)供(gong)電(dian)(dian)過程、電(dian)(dian)氣主(zhu)結線、相關(guan)高壓(ya)配電(dian)(dian)裝(zhuang)置以及(ji)安全操(cao)作規程。系統由(you)兩部(bu)分(fen)組成：軟(ruan)件系統模(mo)擬仿真2個(ge)牽(qian)引變電(dian)(dian)所（1#、2#）、1個(ge)開閉所（主(zhu)供(gong)車(che)站2#側(ce)線）、2個(ge)分(fen)區所，供(gong)電(dian)(dian)方式采用直(zhi)供(gong)加回(hui)流線方式，形成一套(tao)完(wan)整(zheng)的(de)(de)(de)(de)牽(qian)引供(gong)電(dian)(dian)（正常或(huo)者故障狀態(tai)(tai)）以及(ji)實(shi)現(xian)電(dian)(dian)源側(ce)、母聯側(ce)、饋出側(ce)聯鎖；硬(ying)件模(mo)擬系統（接觸網供(gong)電(dian)(dian)控制箱）向(xiang)各段接觸網供(gong)電(dian)(dian)，并通過串口接收(shou)來自軟(ruan)件界面各隔離開關(guan)和(he)斷路(lu)器的(de)(de)(de)(de)操(cao)作信號(hao)實(shi)現(xian)各段接觸網供(gong)電(dian)(dian)狀態(tai)(tai)的(de)(de)(de)(de)變換。

1、接觸網沙盤模型(xing)

      沙盤設(she)有(you)(you)1個(ge)(ge)既有(you)(you)鐵路(lu)中(zhong)間站(zhan)、或N個(ge)(ge)既有(you)(you)線(xian)(xian)(xian)中(zhong)間車站(zhan)、雙線(xian)(xian)(xian)區間、綜合橋梁、隧道(dao)、涵洞，全整的圓曲(qu)線(xian)(xian)(xian)、平交(jiao)道(dao)口、設(she)典型(xing)道(dao)岔自動控(kong)(kong)制(zhi)；2個(ge)(ge)牽(qian)引(yin)變(bian)電(dian)(dian)所(suo)、2個(ge)(ge)分區亭(ting)、1個(ge)(ge)開(kai)閉所(suo)（內(nei)部(bu)結構(gou)清(qing)楚，原理準確，通(tong)電(dian)(dian)演(yan)示）與1個(ge)(ge)AT所(suo)(靜(jing)態模型(xing))。既有(you)(you)線(xian)(xian)(xian)接觸網（可通(tong)電(dian)(dian)）采用(yong)半補償懸掛(gua)裝(zhuang)置與全補償懸掛(gua)裝(zhuang)置，四股道(dao)車站(zhan)采用(yong)橫(heng)跨（兩(liang)個(ge)(ge)軟(ruan)橫(heng)跨和兩(liang)個(ge)(ge)硬橫(heng)跨）。線(xian)(xian)(xian)路(lu)上設(she)有(you)(you)分段絕緣器(qi)、錨段關節(jie)、中(zhong)心錨節(jie)、饋電(dian)(dian)線(xian)(xian)(xian)、電(dian)(dian)連接器(qi)、回流(liu)線(xian)(xian)(xian)等設(she)備及(ji)各種線(xian)(xian)(xian)路(lu)、信(xin)(xin)號(hao)標(biao)志并可通(tong)電(dian)(dian)演(yan)示及(ji)控(kong)(kong)制(zhi)，信(xin)(xin)號(hao)設(she)自動閉塞。接觸線(xian)(xian)(xian)、鋼軌(gui)均為(wei)銅(tong)制(zhi)。配遙(yao)控(kong)(kong)電(dian)(dian)力機車兩(liang)臺(tai)運(yun)行。整體形象(xiang)逼真，結構(gou)清(qing)楚，制(zhi)作精美，采用(yong)計(ji)算(suan)機控(kong)(kong)制(zhi)系統(tong) ，CRH2型(xing)動車組從接觸網受電(dian)(dian)運(yun)行。

3、牽(qian)引變電模型

    沙盤設置2個牽引(yin)變電(dian)所(suo)(suo)（1#、2#）、1個開閉(bi)所(suo)(suo)（主(zhu)供車站(zhan)2#側線）、2個分區所(suo)(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、微機聯鎖及(ji)牽引(yin)供電(dian)系統操(cao)作臺

       系統實(shi)(shi)(shi)現牽(qian)引變電(dian)(dian)所(suo)、開閉所(suo)、分區所(suo)的計算(suan)機綜合控(kong)(kong)制(zhi)(zhi)功(gong)能(neng)。利用(yong)計算(suan)機控(kong)(kong)制(zhi)(zhi)軟件實(shi)(shi)(shi)現對牽(qian)引供(gong)(gong)電(dian)(dian)的控(kong)(kong)制(zhi)(zhi)。真實(shi)(shi)(shi)再現牽(qian)引供(gong)(gong)電(dian)(dian)在不同運行方(fang)式和運行狀態下控(kong)(kong)制(zhi)(zhi)及操作功(gong)能(neng)，通過軟件界面實(shi)(shi)(shi)現真實(shi)(shi)(shi)供(gong)(gong)電(dian)(dian)系統的調度仿真。
