接觸網及牽引供電沙盤

     全面(mian)分析我國(guo)當前(qian)電氣化鐵(tie)道(dao)牽(qian)(qian)引供(gong)電技術、接(jie)觸網(wang)特點和(he)安(an)全操(cao)(cao)(cao)作(zuo)規程(cheng)的基礎上，通過計(ji)算(suan)機仿(fang)真(zhen)模擬電氣化鐵(tie)道(dao)牽(qian)(qian)引供(gong)電所(suo)(suo)涉及的供(gong)電過程(cheng)、電氣主結線、相關高壓配電裝置以及安(an)全操(cao)(cao)(cao)作(zuo)規程(cheng)。系統(tong)由兩(liang)部分組成：軟件系統(tong)模擬仿(fang)真(zhen)2個牽(qian)(qian)引變(bian)(bian)電所(suo)(suo)（1#、2#）、1個開閉所(suo)(suo)（主供(gong)車站2#側線）、2個分區(qu)所(suo)(suo)，供(gong)電方式(shi)采用(yong)直供(gong)加(jia)回(hui)流線方式(shi)，形成一套完整的牽(qian)(qian)引供(gong)電（正(zheng)常(chang)或者故障狀態）以及實現電源側、母(mu)聯側、饋出側聯鎖；硬件模擬系統(tong)（接(jie)觸網(wang)供(gong)電控(kong)制箱）向各(ge)段接(jie)觸網(wang)供(gong)電，并(bing)通過串口接(jie)收來自軟件界面(mian)各(ge)隔離開關和(he)斷路器的操(cao)(cao)(cao)作(zuo)信號實現各(ge)段接(jie)觸網(wang)供(gong)電狀態的變(bian)(bian)換(huan)。

1、接觸網沙盤模型

      沙盤設(she)有(you)(you)1個既有(you)(you)鐵路中(zhong)(zhong)間站(zhan)、或N個既有(you)(you)線(xian)(xian)中(zhong)(zhong)間車(che)站(zhan)、雙線(xian)(xian)區(qu)(qu)間、綜合橋梁、隧(sui)道(dao)、涵洞，全整的圓曲線(xian)(xian)、平(ping)交(jiao)道(dao)口、設(she)典型道(dao)岔(cha)自動(dong)控(kong)制(zhi)(zhi)；2個牽引變(bian)電(dian)(dian)(dian)所、2個分區(qu)(qu)亭、1個開閉(bi)所（內部結構清(qing)(qing)楚(chu)(chu)，原理準確(que)，通電(dian)(dian)(dian)演(yan)示）與1個AT所(靜態模型)。既有(you)(you)線(xian)(xian)接(jie)觸(chu)(chu)網(wang)（可(ke)通電(dian)(dian)(dian)）采用半(ban)補償懸(xuan)掛(gua)裝(zhuang)置(zhi)與全補償懸(xuan)掛(gua)裝(zhuang)置(zhi)，四股道(dao)車(che)站(zhan)采用橫跨（兩個軟橫跨和兩個硬(ying)橫跨）。線(xian)(xian)路上(shang)設(she)有(you)(you)分段絕(jue)緣器、錨(mao)段關節(jie)(jie)、中(zhong)(zhong)心錨(mao)節(jie)(jie)、饋電(dian)(dian)(dian)線(xian)(xian)、電(dian)(dian)(dian)連接(jie)器、回流線(xian)(xian)等設(she)備及各(ge)種線(xian)(xian)路、信(xin)號標(biao)志并可(ke)通電(dian)(dian)(dian)演(yan)示及控(kong)制(zhi)(zhi)，信(xin)號設(she)自動(dong)閉(bi)塞。接(jie)觸(chu)(chu)線(xian)(xian)、鋼軌均為銅制(zhi)(zhi)。配遙控(kong)電(dian)(dian)(dian)力機車(che)兩臺運行(xing)。整體形象逼真，結構清(qing)(qing)楚(chu)(chu)，制(zhi)(zhi)作精美，采用計算機控(kong)制(zhi)(zhi)系(xi)統 ，CRH2型動(dong)車(che)組從接(jie)觸(chu)(chu)網(wang)受電(dian)(dian)(dian)運行(xing)。

3、牽引(yin)變電模型

    沙盤設置2個牽引變電所(suo)（1#、2#）、1個開閉所(suo)（主(zhu)供車(che)站2#側線）、2個分區所(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、微機聯鎖及牽(qian)引供電系統操作臺

       系統(tong)實(shi)現牽引(yin)變電所、開(kai)閉所、分區所的計(ji)算機綜合控(kong)(kong)制功能(neng)。利用計(ji)算機控(kong)(kong)制軟件實(shi)現對牽引(yin)供電的控(kong)(kong)制。真實(shi)再現牽引(yin)供電在不同運(yun)行方式和運(yun)行狀態下控(kong)(kong)制及(ji)操作功能(neng)，通過軟件界(jie)面實(shi)現真實(shi)供電系統(tong)的調度(du)仿真。
