預裝式箱式變電站的基本結構與運行、維護，一文全知曉

說變(bian)(bian)箱式(shi)變(bian)(bian)電站，一(yi)般分為預裝式(shi)與一(yi)體式(shi)兩種(zhong)，它們的另一(yi)種(zhong)稱為分別為歐式(shi)與美式(shi)箱變(bian)(bian)。本(ben)(ben)文說預裝式(shi)箱變(bian)(bian)的基本(ben)(ben)結構，以及(ji)它們在運維上的事項。

所謂預(yu)裝(zhuang)，就(jiu)是將(jiang)用于變(bian)壓(ya)的(de)電(dian)氣設備進行箱(xiang)體內(nei)的(de)預(yu)制、安裝(zhuang)，通過科學合理的(de)接線，將(jiang)各(ge)個功能協同工作，達(da)到穩(wen)定(ding)變(bian)壓(ya)配電(dian)的(de)目的(de)。預(yu)裝(zhuang)式變(bian)電(dian)站(zhan)在箱(xiang)體內(nei)分為(wei)高壓(ya)室、變(bian)壓(ya)器室、低(di)壓(ya)室組成(cheng)。

1、高壓室

10KV高(gao)壓(ya)(ya)電路通過排線(xian)進(jin)(jin)入高(gao)壓(ya)(ya)室(shi)內(nei)，高(gao)壓(ya)(ya)室(shi)內(nei)通常有高(gao)壓(ya)(ya)進(jin)(jin)線(xian)柜(ju)、高(gao)壓(ya)(ya)出線(xian)柜(ju)或者高(gao)壓(ya)(ya)環網柜(ju)或者高(gao)壓(ya)(ya)計量柜(ju)。

2、變壓(ya)器(qi)室(shi)。

這里就是(shi)放置變(bian)壓(ya)器的地方(fang)，通過變(bian)壓(ya)器將接入的電(dian)(dian)(dian)(dian)(dian)壓(ya)進行變(bian)壓(ya)，變(bian)成(cheng)需要的電(dian)(dian)(dian)(dian)(dian)壓(ya)。變(bian)壓(ya)器是(shi)一(yi)(yi)種用于電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)轉換(huan)的電(dian)(dian)(dian)(dian)(dian)器設備，它可(ke)以把一(yi)(yi)種電(dian)(dian)(dian)(dian)(dian)壓(ya)、電(dian)(dian)(dian)(dian)(dian)流的交(jiao)流電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)轉換(huan)成(cheng)相同(tong)頻率的另一(yi)(yi)種電(dian)(dian)(dian)(dian)(dian)壓(ya)、電(dian)(dian)(dian)(dian)(dian)流的交(jiao)流電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)，其(qi)作用是(shi)改變(bian)電(dian)(dian)(dian)(dian)(dian)壓(ya)的高低。

3、低壓室。

低(di)壓(ya)(ya)室則(ze)是(shi)變壓(ya)(ya)器的低(di)壓(ya)(ya)輸出端(duan)引進后的切換保護配電設備箱(xiang)體。

“箱(xiang)變”的(de)安裝環境要求：

在安裝箱(xiang)式變(bian)電站的時候，所在地(di)(di)塊應(ying)該(gai)選擇高出，不(bu)能放在低洼處(chu)(chu)的環(huan)境，以(yi)免(mian)遇水灌入(ru)箱(xiang)內影響運(yun)行。箱(xiang)體與接地(di)(di)網(wang)必須(xu)有兩(liang)處(chu)(chu)可靠的連接，箱(xiang)變(bian)接地(di)(di)和接零可共用一接地(di)(di)網(wang)。
