我(wo)(wo)國(guo)(guo)變壓(ya)器(qi)行業(ye)(ye)起步比發達國(guo)(guo)家(jia)(jia)要晚的多，在建國(guo)(guo)初期，我(wo)(wo)國(guo)(guo)變壓(ya)器(qi)行業(ye)(ye)發展(zhan)的十分緩(huan)慢，企業(ye)(ye)生產能(neng)力不足，國(guo)(guo)內的需(xu)求需(xu)要依靠進口來解(jie)決。在改(gai)革開放(fang)后，由于(yu)市場競爭機制(zhi)的引入，各變壓(ya)器(qi)企業(ye)(ye)積(ji)極(ji)進行體制(zhi)改(gai)革來適應(ying)(ying)市場經濟，我(wo)(wo)國(guo)(guo)變壓(ya)器(qi)行業(ye)(ye)得到了 快速的發展(zhan)。但是由于(yu)對市場經濟的適應(ying)(ying)需(xu)要一(yi)定的時間和過程(cheng)，很多國(guo)(guo)內變壓(ya)器(qi)廠家(jia)(jia)因此放(fang)緩(huan)了新(xin)產品、新(xin)技術(shu)研發的腳步，人才(cai)培養跟不上，我(wo)(wo)國(guo)(guo)變壓(ya)器(qi)企業(ye)(ye)的開發能(neng)力就十分有限。

從現在我(wo)國(guo)變(bian)壓器(qi)行業(ye)(ye)的(de)(de)發(fa)展(zhan)現狀看，我(wo)國(guo)變(bian)壓器(qi)的(de)(de)行業(ye)(ye)規模(mo)雖然比(bi)較龐大，產(chan)能也(ye)較過去提高了很多(duo)。但是(shi)我(wo)國(guo)變(bian)壓器(qi)在市場上與國(guo)外大型企業(ye)(ye)相(xiang)比(bi)依然競(jing)爭(zheng)力不足。而且，變(bian)壓器(qi)行業(ye)(ye)魚(yu)龍混(hun)雜(za)，監管(guan)不力，使市場上以次充好的(de)(de)現象時有發(fa)生，擾(rao)亂了市場競(jing)爭(zheng)秩序，也(ye)極(ji)大的(de)(de)破(po)壞了我(wo)國(guo)變(bian)壓器(qi)行業(ye)(ye)的(de)(de)形象。

配(pei)電柜(ju)有(you)時(shi)又被稱為配(pei)電箱，是一(yi)個集(ji)成了用(yong)于電能分配(pei)的(de)電氣(qi)元(yuan)件：空氣(qi)開關、斷(duan)(duan)路(lu)器、各種型號的(de)刀閘、接(jie)線端子、保護(hu)設(she)(she)備（熱繼電器、、時(shi)間繼電器、熔斷(duan)(duan)器之類，高級(ji)的(de)還(huan)有(you)保護(hu)裝置(zhi)等(deng)）、測量設(she)(she)備（電壓表(biao)、電流表(biao)、頻率表(biao)、功率表(biao)等(deng)，還(huan)有(you)互感器和各種傳感器）的(de)柜(ju)體。

配(pei)(pei)電(dian)(dian)(dian)(dian)(dian)(dian)柜因其良(liang)好的(de)功(gong)能(neng)被廣泛應用(yong)于居民樓、學校和(he)醫(yi)院等(deng)生活用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)配(pei)(pei)電(dian)(dian)(dian)(dian)(dian)(dian)控制。有人可能(neng)會(hui)問，那為什么我(wo)們(men)平時看不到配(pei)(pei)電(dian)(dian)(dian)(dian)(dian)(dian)柜呢？因為有的(de)配(pei)(pei)電(dian)(dian)(dian)(dian)(dian)(dian)柜體積(ji)很小(xiao)，大部分都是暗設(she)在(zai)(zai)墻體內，體積(ji)較大的(de)都集中(zhong)安裝在(zai)(zai)配(pei)(pei)電(dian)(dian)(dian)(dian)(dian)(dian)室內，所以在(zai)(zai)日常生活中(zhong)很少能(neng)夠親眼(yan)看到配(pei)(pei)電(dian)(dian)(dian)(dian)(dian)(dian)柜。在(zai)(zai)企業廠房和(he)車間經(jing)常會(hui)看到配(pei)(pei)電(dian)(dian)(dian)(dian)(dian)(dian)柜，或者配(pei)(pei)電(dian)(dian)(dian)(dian)(dian)(dian)箱，比(bi)如照(zhao)明配(pei)(pei)電(dian)(dian)(dian)(dian)(dian)(dian)柜和(he)動力配(pei)(pei)電(dian)(dian)(dian)(dian)(dian)(dian)柜等(deng)。一(yi)般(ban)來說，配(pei)(pei)電(dian)(dian)(dian)(dian)(dian)(dian)柜主要(yao)分一(yi)級(ji)、二級(ji)和(he)低級(ji)三(san)級(ji)配(pei)(pei)電(dian)(dian)(dian)(dian)(dian)(dian)設(she)備(bei)。

配電(dian)(dian)柜(ju)主要有兩方(fang)(fang)面(mian)的(de)(de)作用(yong)(yong)：一是(shi)對(dui)用(yong)(yong)電(dian)(dian)設(she)備進(jin)行配電(dian)(dian)和(he)控制，二是(shi)在電(dian)(dian)路出(chu)現過(guo)載(zai)、短路和(he)漏電(dian)(dian)時，提供斷電(dian)(dian)保(bao)護，當電(dian)(dian)路出(chu)現故障時，有利(li)于控制故障范圍也(ye)方(fang)(fang)便(bian)(bian)(bian)快(kuai)捷找出(chu)故障點及(ji)時加以排除，無需大(da)面(mian)積停電(dian)(dian)。另外，配電(dian)(dian)柜(ju)內方(fang)(fang)便(bian)(bian)(bian)放(fang)置(zhi)各種保(bao)護設(she)備，如防止短路的(de)(de)熔斷器（保(bao)險(xian)絲），防止過(guo)載(zai)的(de)(de)空氣開關等，可以對(dui)線路和(he)用(yong)(yong)電(dian)(dian)設(she)備起到(dao)保(bao)護作用(yong)(yong)。也(ye)就是(shi)說把東西集中到(dao)一起，方(fang)(fang)便(bian)(bian)(bian)維護、檢查。特(te)別是(shi)如今的(de)(de)用(yong)(yong)電(dian)(dian)量(liang)很大(da)的(de)(de)情況(kuang)下，沒有配電(dian)(dian)柜(ju)是(shi)不可行的(de)(de)，極(ji)大(da)的(de)(de)幫助(zhu)到(dao)我們改善用(yong)(yong)電(dian)(dian)的(de)(de)便(bian)(bian)(bian)利(li)性。

配(pei)電(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)(ju)結構復雜，輸出電(dian)(dian)(dian)(dian)(dian)路(lu)容(rong)量(liang)也比(bi)較大，它是供(gong)電(dian)(dian)(dian)(dian)(dian)系統的(de)動(dong)(dong)力配(pei)電(dian)(dian)(dian)(dian)(dian)中心，會(hui)被安裝在(zai)變電(dian)(dian)(dian)(dian)(dian)站內，負(fu)責將(jiang)電(dian)(dian)(dian)(dian)(dian)能(neng)分(fen)配(pei)給二級(ji)配(pei)電(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)(ju)。配(pei)電(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)(ju)分(fen)為動(dong)(dong)力配(pei)電(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)(ju)和電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)控(kong)制中心，兩者的(de)應(ying)用部位相反，動(dong)(dong)力配(pei)電(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)(ju)主(zhu)要(yao)(yao)是在(zai)回路(lu)少、負(fu)荷分(fen)散的(de)部位，而電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)控(kong)制中心應(ying)用于(yu)回路(lu)多，負(fu)荷集(ji)中的(de)部位。它主(zhu)要(yao)(yao)是承接一級(ji)配(pei)電(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)(ju)分(fen)配(pei)電(dian)(dian)(dian)(dian)(dian)能(neng)，，并將(jiang)其分(fen)配(pei)給就(jiu)近(jin)的(de)負(fu)荷。配(pei)電(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)(ju)主(zhu)要(yao)(yao)是照明配(pei)電(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)(ju)和動(dong)(dong)力配(pei)電(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)(ju)，它們的(de)容(rong)量(liang)比(bi)較小，布置也較為分(fen)散，主(zhu)要(yao)(yao)是負(fu)責控(kong)制最低級(ji)的(de)負(fu)荷配(pei)電(dian)(dian)(dian)(dian)(dian)。

高低壓(ya)配電(dian)(dian)柜的(de)(de)安全使(shi)用(yong)問題一直(zhi)是人(ren)們關注的(de)(de)重點，以下的(de)(de)注意(yi)事項需要(yao)了解。在全部(bu)和部(bu)分(fen)帶電(dian)(dian)的(de)(de)盤上進(jin)行(xing)工(gong)(gong)作，應(ying)將檢修設備(bei)與(yu)運行(xing)設備(bei)以明顯標志隔開。在運行(xing)的(de)(de)電(dian)(dian)流互(hu)感器(qi)二(er)(er)次(ci)回(hui)路(lu)上工(gong)(gong)作時，嚴禁(jin)(jin)將電(dian)(dian)流回(hui)路(lu)斷(duan)開。為了可(ke)靠地將電(dian)(dian)流互(hu)感器(qi)二(er)(er)次(ci)線圈(quan)短(duan)(duan)路(lu)，必須使(shi)用(yong)短(duan)(duan)路(lu)片和短(duan)(duan)路(lu)線，禁(jin)(jin)止使(shi)用(yong)導線纏(chan)繞。禁(jin)(jin)止在電(dian)(dian)流互(hu)感器(qi)與(yu)短(duan)(duan)路(lu)端(duan)子之(zhi)間的(de)(de)回(hui)路(lu)和導線上進(jin)行(xing)任(ren)何工(gong)(gong)作。二(er)(er)次(ci)回(hui)路(lu)通(tong)電(dian)(dian)或耐壓(ya)試驗前應(ying)通(tong)知值班員(yuan)和有(you)關人(ren)員(yuan)，并派人(ren)看守現(xian)場(chang)，檢查回(hui)路(lu)，確認無人(ren)工(gong)(gong)作后方可(ke)加壓(ya)。檢查斷(duan)電(dian)(dian)保護盒二(er)(er)次(ci)回(hui)路(lu)的(de)(de)工(gong)(gong)作人(ren)員(yuan)，未經值班人(ren)員(yuan)許可(ke)，不準進(jin)行(xing)任(ren)何倒閘操作。

不(bu)(bu)過，高低壓(ya)(ya)配電柜在安裝、驗收(shou)、交接(jie)性(xing)試驗試車、運(yun)行與(yu)維護等方面應遵守電力部門要求執行的(de)(de)各項(xiang)規定外。還應注意以下事項(xiang)：用(yong)戶收(shou)貨時應按有關規定仔細檢(jian)查，對(dui)于不(bu)(bu)馬上(shang)安裝的(de)(de)產品，應按正(zheng)常使用(yong)條件規定，存(cun)放于適(shi)當的(de)(de)場所。產品應采用(yong)專(zhuan)用(yong)吊(diao)具底(di)部起吊(diao)。產品水(shui)平安放在事先(xian)做好的(de)(de)基(ji)(ji)礎上(shang)，裝好四只地腳(jiao)螺栓（可采用(yong)二次澆灌法），然后將產品底(di)座(zuo)與(yu)基(ji)(ji)礎之(zhi)間的(de)(de)縫隙(xi)用(yong)水(shui)泥沙漿抹封(feng)，以免雨水(shui)進(jin)入電纜(lan)室。通(tong)過高、低壓(ya)(ya)室的(de)(de)底(di)封(feng)板接(jie)入高、低壓(ya)(ya)電纜(lan)。電纜(lan)與(yu)穿管之(zhi)間的(de)(de)縫隙(xi)密(mi)封(feng)防水(shui)。

高(gao)低壓(ya)配電(dian)(dian)柜(ju)高(gao)壓(ya)側(ce)無論是采用(yong)(yong)(yong)架空進(jin)(jin)線(xian)還是電(dian)(dian)纜(lan)進(jin)(jin)線(xian)，均(jun)應在變電(dian)(dian)站(zhan)附(fu)近設置高(gao)壓(ya)側(ce)進(jin)(jin)線(xian)的(de)(de)明(ming)顯可見的(de)(de)斷(duan)口(kou)（如(ru)跌(die)落式熔斷(duan)器(qi)等）。從(cong)而向維修操作(zuo)(zuo)人員明(ming)確顯示變電(dian)(dian)站(zhan)內是否(fou)帶電(dian)(dian)。以確保維修操作(zuo)(zuo)人員的(de)(de)安(an)(an)全。產品安(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)就位后(hou)應做(zuo)好可靠接(jie)地(di)(di)(di)(di)：電(dian)(dian)站(zhan)底座(zuo)槽鋼上的(de)(de)兩個主接(jie)地(di)(di)(di)(di)端子、變壓(ya)器(qi)中(zhong)(zhong)性點及(ji)外殼(ke)、避雷器(qi)下樁頭等均(jun)應分別(bie)由安(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)部門(men)直接(jie)接(jie)地(di)(di)(di)(di)。所(suo)在接(jie)地(di)(di)(di)(di)應共用(yong)(yong)(yong)一組(zu)接(jie)地(di)(di)(di)(di)裝(zhuang)(zhuang)(zhuang)(zhuang)置，其接(jie)地(di)(di)(di)(di)電(dian)(dian)阻應小于(yu)4歐姆，從(cong)接(jie)地(di)(di)(di)(di)網引至本(ben)產品的(de)(de)接(jie)地(di)(di)(di)(di)引線(xian)應不少于(yu)兩條。在運(yun)行中(zhong)(zhong)的(de)(de)電(dian)(dian)壓(ya)互感器(qi)二次回路(lu)上工作(zuo)(zuo)嚴格防(fang)止短(duan)路(lu)或接(jie)地(di)(di)(di)(di)，應使用(yong)(yong)(yong)絕緣(yuan)工具(ju)、戴絕緣(yuan)手套，必要時在工作(zuo)(zuo)前停用(yong)(yong)(yong)有關(guan)繼電(dian)(dian)保護裝(zhuang)(zhuang)(zhuang)(zhuang)置。接(jie)臨時負載時，必須裝(zhuang)(zhuang)(zhuang)(zhuang)有專用(yong)(yong)(yong)的(de)(de)開關(guan)和熔斷(duan)器(qi)。
