3、牽引變電模型

    沙盤設置2個(ge)(ge)牽(qian)引變(bian)電(dian)所（1#、2#）、1個(ge)(ge)開(kai)閉所（主供車(che)站2#側(ce)線）、2個(ge)(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(wei)機聯鎖及牽引供(gong)電系統操作臺(tai)

       系(xi)統(tong)實(shi)(shi)現牽引變電(dian)所、開閉所、分區(qu)所的計算(suan)機綜合控(kong)制(zhi)功(gong)能。利用計算(suan)機控(kong)制(zhi)軟件(jian)實(shi)(shi)現對牽引供電(dian)的控(kong)制(zhi)。真實(shi)(shi)再現牽引供電(dian)在不同運行(xing)方式(shi)和運行(xing)狀(zhuang)態下控(kong)制(zhi)及操作功(gong)能，通過軟件(jian)界面(mian)實(shi)(shi)現真實(shi)(shi)供電(dian)系(xi)統(tong)的調度仿(fang)真。
