油浸式變壓器的內部是有著很多的組別的，各種的組別是構成變壓器的基本的重要的組成部分，常見的變壓器的組別是有多種的，要不斷地進行實現油浸式變壓器的組別的各種的連接的正確性能，使得變壓器的組別能夠穩定的實現電流和電壓的變壓效果。那么，變壓器的組別有哪些呢?是怎么進行連接的呢?就這兩個問題我們的技術人員給出了解答!

　　首先(xian)，有利于抑(yi)(yi)制(zhi)高(gao)次(ci)諧(xie)波(bo)(bo)(bo)(bo)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)。對Yyn0結線(xian)的(de)三(san)相(xiang)油浸式變壓器 ，原(yuan)邊(bian)星形(xing)(xing)連接(jie)而無中(zhong)(zhong)線(xian)，故三(san)次(ci)諧(xie)波(bo)(bo)(bo)(bo)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)不能(neng)流(liu)(liu)通。原(yuan)邊(bian)激磁電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)波(bo)(bo)(bo)(bo)形(xing)(xing)為正弦波(bo)(bo)(bo)(bo)時，則(ze)鐵芯(xin)中(zhong)(zhong)磁通為平頂波(bo)(bo)(bo)(bo)，副邊(bian)感(gan)應電(dian)(dian)(dian)(dian)(dian)(dian)勢波(bo)(bo)(bo)(bo)形(xing)(xing)所(suo)含高(gao)次(ci)諧(xie)波(bo)(bo)(bo)(bo)分量大;激磁電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)中(zhong)(zhong)以三(san)次(ci)諧(xie)波(bo)(bo)(bo)(bo)為主的(de)高(gao)次(ci)諧(xie)波(bo)(bo)(bo)(bo)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)在原(yuan)邊(bian)接(jie)成三(san)角(jiao)形(xing)(xing)條(tiao)件下，可(ke)在原(yuan)邊(bian)形(xing)(xing)成環(huan)流(liu)(liu)，與原(yuan)邊(bian)接(jie)成星形(xing)(xing)相(xiang)比，有利于抑(yi)(yi)制(zhi)高(gao)次(ci)諧(xie)波(bo)(bo)(bo)(bo)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)。在當前電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)中(zhong)(zhong)接(jie)用電(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)元件、氣體(ti)放電(dian)(dian)(dian)(dian)(dian)(dian)燈等(deng)日益廣泛、其功率越來越大的(de)情況下，會(hui)使得(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)波(bo)(bo)(bo)(bo)形(xing)(xing)畸(ji)變。即使三(san)相(xiang)負荷平衡，中(zhong)(zhong)性線(xian)中(zhong)(zhong)也流(liu)(liu)過(guo)以3次(ci)諧(xie)波(bo)(bo)(bo)(bo)為主的(de)高(gao)次(ci)諧(xie)波(bo)(bo)(bo)(bo)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)。配電(dian)(dian)(dian)(dian)(dian)(dian)油浸式變壓器的(de)原(yuan)邊(bian)(常(chang)為10KV側)采用三(san)角(jiao)形(xing)(xing)結線(xian)就抑(yi)(yi)制(zhi)了此(ci)類高(gao)次(ci)諧(xie)波(bo)(bo)(bo)(bo)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)，這樣就能(neng)保(bao)證供電(dian)(dian)(dian)(dian)(dian)(dian)波(bo)(bo)(bo)(bo)形(xing)(xing)的(de)質量。

　　第二，有利于單相(xiang)(xiang)接(jie)地短(duan)路(lu)(lu)(lu)(lu)故障的(de)切除：原邊(bian)(bian)(高壓)接(jie)成三角形(xing)(D接(jie))，繞組內(nei)可(ke)通過零(ling)(ling)(ling)序(xu)循環電(dian)流(liu)(liu)(liu)(感應產(chan)(chan)生)，因而(er)可(ke)與低(di)(di)壓繞組零(ling)(ling)(ling)序(xu)電(dian)流(liu)(liu)(liu)互相(xiang)(xiang)平衡、去磁(ci)(ci)，因此，副邊(bian)(bian)(低(di)(di)壓側(ce)(ce))零(ling)(ling)(ling)序(xu)阻抗很小;若原邊(bian)(bian)(高壓側(ce)(ce))星接(jie)(Y接(jie))，繞組不能流(liu)(liu)(liu)過零(ling)(ling)(ling)序(xu)電(dian)流(liu)(liu)(liu)，低(di)(di)壓側(ce)(ce)激(ji)磁(ci)(ci)時(shi)，其(qi)(qi)零(ling)(ling)(ling)序(xu)電(dian)流(liu)(liu)(liu)在(zai)油浸式(shi)變(bian)壓器(qi)鐵(tie)芯(xin)中產(chan)(chan)生零(ling)(ling)(ling)序(xu)磁(ci)(ci)通，但其(qi)(qi)磁(ci)(ci)路(lu)(lu)(lu)(lu)不能在(zai)鐵(tie)芯(xin)內(nei)形(xing)成閉合(he)，要走鐵(tie)芯(xin)外(wai)面的(de)空氣，其(qi)(qi)磁(ci)(ci)阻很大，油浸式(shi)變(bian)壓器(qi)的(de)零(ling)(ling)(ling)序(xu)阻抗較大。若發生單相(xiang)(xiang)短(duan)路(lu)(lu)(lu)(lu)，其(qi)(qi)短(duan)路(lu)(lu)(lu)(lu)電(dian)流(liu)(liu)(liu)值就會相(xiang)(xiang)對地減小，致使(shi)在(zai)很多情況(kuang)下，其(qi)(qi)單相(xiang)(xiang)接(jie)地短(duan)路(lu)(lu)(lu)(lu)電(dian)流(liu)(liu)(liu)幾乎不能使(shi)低(di)(di)壓斷(duan)路(lu)(lu)(lu)(lu)器(qi)快速動作或使(shi)熔斷(duan)器(qi)迅速熔斷(duan)。通常，在(zai)相(xiang)(xiang)同(tong)的(de)條件(jian)下，Dyn11結(jie)(jie)線(xian)(xian)的(de)變(bian)壓器(qi) 配電(dian)系統的(de)單相(xiang)(xiang)短(duan)路(lu)(lu)(lu)(lu)電(dian)流(liu)(liu)(liu)為Yyn0結(jie)(jie)線(xian)(xian)時(shi)的(de)3倍以上。因此，Dyn11結(jie)(jie)線(xian)(xian)有利于單相(xiang)(xiang)接(jie)地短(duan)路(lu)(lu)(lu)(lu)故障的(de)切除。

　　第三(san)(san)，能(neng)(neng)(neng)充分(fen)(fen)利用(yong)油(you)(you)浸(jin)(jin)(jin)式(shi)(shi)變(bian)(bian)壓(ya)(ya)器(qi)(qi)的(de)(de)(de)設備能(neng)(neng)(neng)力：對(dui)(dui)于配(pei)電(dian)(dian)(dian)油(you)(you)浸(jin)(jin)(jin)式(shi)(shi)變(bian)(bian)壓(ya)(ya)器(qi)(qi) ，照明(ming)、空調(diao)、電(dian)(dian)(dian)炊、電(dian)(dian)(dian)熱等(deng)餐廚家(jia)電(dian)(dian)(dian)220伏單(dan)相(xiang)(xiang)(xiang)負荷(he)往(wang)往(wang)占很大比重。盡(jin)管在(zai)工程設計及安裝時(shi)(shi)(shi)，盡(jin)可能(neng)(neng)(neng)將各(ge)個(ge)單(dan)相(xiang)(xiang)(xiang)負荷(he)均勻分(fen)(fen)布在(zai)三(san)(san)相(xiang)(xiang)(xiang)上，而(er)由于運行時(shi)(shi)(shi)的(de)(de)(de)情(qing)況千(qian)變(bian)(bian)萬化(hua)，有時(shi)(shi)(shi)可能(neng)(neng)(neng)出現(xian)三(san)(san)相(xiang)(xiang)(xiang)嚴重不(bu)(bu)平衡現(xian)象。三(san)(san)相(xiang)(xiang)(xiang)負荷(he)不(bu)(bu)平衡或每(mei)相(xiang)(xiang)(xiang)功率(lv)因數相(xiang)(xiang)(xiang)差(cha)較(jiao)大、油(you)(you)浸(jin)(jin)(jin)式(shi)(shi)變(bian)(bian)壓(ya)(ya)器(qi)(qi)處(chu)于不(bu)(bu)對(dui)(dui)稱(cheng)運行狀態，副邊中(zhong)性線(xian)就(jiu)有電(dian)(dian)(dian)流(liu)(liu)通過(guo)。上述《規(gui)范》中(zhong)第6.0.8條明(ming)確規(gui)定(ding)(ding)：“在(zai)TN和TT系統接地(di)型式(shi)(shi)的(de)(de)(de)低(di)壓(ya)(ya)電(dian)(dian)(dian)網中(zhong)，當選用(yong)Yyn0結(jie)線(xian)組(zu)(zu)別的(de)(de)(de)三(san)(san)相(xiang)(xiang)(xiang)油(you)(you)浸(jin)(jin)(jin)式(shi)(shi)變(bian)(bian)壓(ya)(ya)器(qi)(qi)時(shi)(shi)(shi)，其(qi)由單(dan)相(xiang)(xiang)(xiang)不(bu)(bu)平衡負荷(he)引起的(de)(de)(de)中(zhong)性線(xian)電(dian)(dian)(dian)流(liu)(liu)不(bu)(bu)得超(chao)過(guo)低(di)壓(ya)(ya)繞組(zu)(zu)額(e)定(ding)(ding)電(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)25%，且其(qi)一相(xiang)(xiang)(xiang)的(de)(de)(de)電(dian)(dian)(dian)流(liu)(liu)在(zai)滿載時(shi)(shi)(shi)不(bu)(bu)得超(chao)過(guo)額(e)定(ding)(ding)電(dian)(dian)(dian)流(liu)(liu)值(zhi)。”這一規(gui)定(ding)(ding)十分(fen)(fen)明(ming)確地(di)限(xian)制了Yyn0結(jie)線(xian)時(shi)(shi)(shi)接用(yong)單(dan)相(xiang)(xiang)(xiang)負荷(he)的(de)(de)(de)容量，從而(er)限(xian)制了Yyn0結(jie)線(xian)配(pei)電(dian)(dian)(dian)油(you)(you)浸(jin)(jin)(jin)式(shi)(shi)變(bian)(bian)壓(ya)(ya)器(qi)(qi)的(de)(de)(de)使用(yong)――此時(shi)(shi)(shi)，油(you)(you)浸(jin)(jin)(jin)式(shi)(shi)變(bian)(bian)壓(ya)(ya)器(qi)(qi)設備能(neng)(neng)(neng)力不(bu)(bu)能(neng)(neng)(neng)充分(fen)(fen)利用(yong)。而(er)Dyn11結(jie)線(xian)方式(shi)(shi)的(de)(de)(de)油(you)(you)浸(jin)(jin)(jin)式(shi)(shi)變(bian)(bian)壓(ya)(ya)器(qi)(qi)，對(dui)(dui)中(zhong)性線(xian)電(dian)(dian)(dian)流(liu)(liu)沒有限(xian)制，可達(da)油(you)(you)浸(jin)(jin)(jin)式(shi)(shi)變(bian)(bian)壓(ya)(ya)器(qi)(qi)低(di)壓(ya)(ya)側之線(xian)(相(xiang)(xiang)(xiang))電(dian)(dian)(dian)流(liu)(liu)，從而(er)能(neng)(neng)(neng)充分(fen)(fen)利用(yong)油(you)(you)浸(jin)(jin)(jin)式(shi)(shi)變(bian)(bian)壓(ya)(ya)器(qi)(qi)的(de)(de)(de)容量、發揮(hui)其(qi)設備能(neng)(neng)(neng)力，尤其(qi)適宜以(yi)單(dan)相(xiang)(xiang)(xiang)負荷(he)為主而(er)出現(xian)三(san)(san)相(xiang)(xiang)(xiang)不(bu)(bu)平衡的(de)(de)(de)配(pei)電(dian)(dian)(dian)變(bian)(bian)壓(ya)(ya)器(qi)(qi)。
