接觸網及牽引供電沙盤

     全(quan)面分(fen)析我國當前電(dian)(dian)氣化鐵道(dao)牽(qian)引(yin)供(gong)(gong)電(dian)(dian)技術、接(jie)觸網(wang)特點和(he)安全(quan)操(cao)作規(gui)程的基礎上，通過計算機仿真模擬電(dian)(dian)氣化鐵道(dao)牽(qian)引(yin)供(gong)(gong)電(dian)(dian)所涉及的供(gong)(gong)電(dian)(dian)過程、電(dian)(dian)氣主結(jie)線(xian)、相(xiang)關(guan)高壓配電(dian)(dian)裝(zhuang)置以及安全(quan)操(cao)作規(gui)程。系統由(you)兩部分(fen)組成：軟件(jian)系統模擬仿真2個牽(qian)引(yin)變電(dian)(dian)所（1#、2#）、1個開閉所（主供(gong)(gong)車站2#側線(xian)）、2個分(fen)區(qu)所，供(gong)(gong)電(dian)(dian)方(fang)式采(cai)用(yong)直供(gong)(gong)加回(hui)流線(xian)方(fang)式，形成一套完整的牽(qian)引(yin)供(gong)(gong)電(dian)(dian)（正常或者(zhe)故(gu)障(zhang)狀態）以及實現電(dian)(dian)源側、母聯(lian)側、饋(kui)出側聯(lian)鎖；硬件(jian)模擬系統（接(jie)觸網(wang)供(gong)(gong)電(dian)(dian)控制箱）向各段(duan)(duan)接(jie)觸網(wang)供(gong)(gong)電(dian)(dian)，并通過串口接(jie)收來(lai)自(zi)軟件(jian)界面各隔離開關(guan)和(he)斷路器的操(cao)作信號實現各段(duan)(duan)接(jie)觸網(wang)供(gong)(gong)電(dian)(dian)狀態的變換(huan)。

1、接觸網(wang)沙盤模型

      沙盤設(she)(she)有(you)1個既有(you)鐵路中間站(zhan)、或N個既有(you)線中間車站(zhan)、雙線區間、綜合(he)橋梁、隧道、涵洞(dong)，全整的圓曲(qu)線、平交道口、設(she)(she)典型(xing)(xing)道岔(cha)自(zi)動(dong)控制(zhi)；2個牽引變電(dian)(dian)所(suo)(suo)、2個分區亭、1個開閉所(suo)(suo)（內部(bu)結構(gou)清(qing)楚，原(yuan)理(li)準確(que)，通電(dian)(dian)演示(shi)）與(yu)1個AT所(suo)(suo)(靜(jing)態模型(xing)(xing))。既有(you)線接(jie)觸(chu)(chu)網（可通電(dian)(dian)）采用半補償(chang)懸(xuan)掛裝置與(yu)全補償(chang)懸(xuan)掛裝置，四股(gu)道車站(zhan)采用橫(heng)(heng)跨（兩個軟橫(heng)(heng)跨和兩個硬橫(heng)(heng)跨）。線路上設(she)(she)有(you)分段(duan)(duan)絕緣(yuan)器、錨段(duan)(duan)關節(jie)、中心錨節(jie)、饋電(dian)(dian)線、電(dian)(dian)連接(jie)器、回流線等設(she)(she)備及(ji)各種線路、信號(hao)標志并(bing)可通電(dian)(dian)演示(shi)及(ji)控制(zhi)，信號(hao)設(she)(she)自(zi)動(dong)閉塞。接(jie)觸(chu)(chu)線、鋼軌均為銅制(zhi)。配遙控電(dian)(dian)力(li)機(ji)車兩臺運行。整體(ti)形(xing)象逼真，結構(gou)清(qing)楚，制(zhi)作精(jing)美，采用計算(suan)機(ji)控制(zhi)系統 ，CRH2型(xing)(xing)動(dong)車組從接(jie)觸(chu)(chu)網受電(dian)(dian)運行。

3、牽(qian)引變電模型

    沙盤設置2個(ge)牽(qian)引變電所（1#、2#）、1個(ge)開閉所（主(zhu)供車(che)站2#側線(xian)）、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(ji)聯鎖及牽引供電系統操作臺(tai)

       系(xi)統(tong)實(shi)(shi)現(xian)(xian)牽引(yin)變電(dian)(dian)所(suo)、開閉所(suo)、分區所(suo)的計(ji)算機(ji)綜合控制功(gong)(gong)能。利用計(ji)算機(ji)控制軟(ruan)件實(shi)(shi)現(xian)(xian)對牽引(yin)供電(dian)(dian)的控制。真(zhen)實(shi)(shi)再現(xian)(xian)牽引(yin)供電(dian)(dian)在不同運(yun)行(xing)方(fang)式和運(yun)行(xing)狀態下控制及操(cao)作(zuo)功(gong)(gong)能，通過軟(ruan)件界面實(shi)(shi)現(xian)(xian)真(zhen)實(shi)(shi)供電(dian)(dian)系(xi)統(tong)的調度仿真(zhen)。
