　　干式變壓器中運行的效率也是比較高的，而且現在的生產力和生活水平也是不斷地進行提高的，常見的干式變壓器是有著一定的鐵芯的，而對于干式變壓器的(de)鐵芯(xin)來(lai)說，也是(shi)(shi)要不斷地(di)進(jin)(jin)(jin)行管理和連(lian)接(jie)(jie)的(de)，只(zhi)有這樣的(de)話干式(shi)變(bian)壓(ya)器(qi)的(de)鐵芯(xin)才會(hui)更加發揮作用，才會(hui)更加安全(quan)。對于干式(shi)變(bian)壓(ya)器(qi)的(de)鐵芯(xin)也是(shi)(shi)要進(jin)(jin)(jin)行嚴格(ge)去連(lian)接(jie)(jie)的(de)，那么常見的(de)干式(shi)變(bian)壓(ya)器(qi)的(de)鐵芯(xin)是(shi)(shi)怎么進(jin)(jin)(jin)行連(lian)接(jie)(jie)的(de)呢?我們(men)還是(shi)(shi)和小編一起來(lai)進(jin)(jin)(jin)行看一下(xia)吧(ba)：

　　運行中干(gan)式(shi)變壓(ya)(ya)器(qi)(qi)(qi)(qi)的(de)(de)(de)鐵(tie)(tie)芯及其他附件(jian)(jian)都處于(yu)繞組周(zhou)圍的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)場內(nei)(nei)，如不接(jie)地(di)(di)(di)(di)(di)(di)，鐵(tie)(tie)芯及其他附件(jian)(jian)必(bi)然感(gan)應一定的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，在(zai)外加(jia)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)(de)(de)作用下(xia)(xia)，當感(gan)應電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)超過對地(di)(di)(di)(di)(di)(di)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)時(shi)，就(jiu)會產(chan)生(sheng)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)現象(xiang)。為(wei)了避(bi)免干(gan)式(shi)變壓(ya)(ya)器(qi)(qi)(qi)(qi)的(de)(de)(de)內(nei)(nei)部(bu)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)，所(suo)(suo)以(yi)(yi)(yi)要(yao)將鐵(tie)(tie)芯接(jie)地(di)(di)(di)(di)(di)(di)。干(gan)式(shi)變壓(ya)(ya)器(qi)(qi)(qi)(qi)的(de)(de)(de)鐵(tie)(tie)心多點(dian)(dian)接(jie)地(di)(di)(di)(di)(di)(di)，接(jie)地(di)(di)(di)(di)(di)(di)點(dian)(dian)之(zhi)(zhi)間形成電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)回(hui)(hui)路(lu)，會造成鐵(tie)(tie)心局部(bu)過熱、氣體繼電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)頻繁動作。嚴重時(shi)會造成鐵(tie)(tie)心局部(bu)燒(shao)損。干(gan)式(shi)變壓(ya)(ya)器(qi)(qi)(qi)(qi)干(gan)式(shi)變壓(ya)(ya)器(qi)(qi)(qi)(qi)鐵(tie)(tie)芯必(bi)須接(jie)地(di)(di)(di)(di)(di)(di)是(shi)(shi)為(wei)了防止干(gan)式(shi)變壓(ya)(ya)器(qi)(qi)(qi)(qi)在(zai)運行或做實驗時(shi)，由于(yu)靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)感(gan)應而在(zai)鐵(tie)(tie)芯和(he)其他金屬構(gou)件(jian)(jian)上產(chan)生(sheng)懸浮電(dian)(dian)(dian)(dian)(dian)(dian)位造成對地(di)(di)(di)(di)(di)(di)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)，所(suo)(suo)以(yi)(yi)(yi)鐵(tie)(tie)芯及其金屬構(gou)件(jian)(jian)除穿(chuan)心螺(luo)桿外，都必(bi)須可靠接(jie)地(di)(di)(di)(di)(di)(di)。按照《(Q/CSG10007-2004)設(she)備預防性試驗規(gui)程(cheng)》 的(de)(de)(de)要(yao)求(qiu)，接(jie)地(di)(di)(di)(di)(di)(di)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)在(zai)正常情(qing)況下(xia)(xia)應該小于(yu)0.1A，1平(ping)方毫(hao)米(mi)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)線就(jiu)可以(yi)(yi)(yi)承受這個電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)了，所(suo)(suo)以(yi)(yi)(yi)對接(jie)地(di)(di)(di)(di)(di)(di)電(dian)(dian)(dian)(dian)(dian)(dian)線的(de)(de)(de)規(gui)格沒(mei)有(you)太大的(de)(de)(de)要(yao)求(qiu)，考慮到可能出現接(jie)地(di)(di)(di)(di)(di)(di)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)偏(pian)大的(de)(de)(de)情(qing)況，一般按照輸出電(dian)(dian)(dian)(dian)(dian)(dian)纜的(de)(de)(de)截面積的(de)(de)(de)一半是(shi)(shi)足(zu)夠的(de)(de)(de)了，還要(yao)說明的(de)(de)(de)是(shi)(shi)，鐵(tie)(tie)心疊片只允(yun)許(xu)一點(dian)(dian)接(jie)地(di)(di)(di)(di)(di)(di)，如果(guo)有(you)兩點(dian)(dian)以(yi)(yi)(yi)上接(jie)地(di)(di)(di)(di)(di)(di)，則接(jie)地(di)(di)(di)(di)(di)(di)各(ge)點(dian)(dian)之(zhi)(zhi)間可能形成回(hui)(hui)路(lu)。當主磁道穿(chuan)過此(ci)閉和(he)回(hui)(hui)路(lu)時(shi)，就(jiu)會在(zai)其中產(chan)生(sheng)循環電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，造成內(nei)(nei)部(bu)過熱事故。
