干(gan)(gan)式變(bian)(bian)(bian)壓(ya)(ya)(ya)器工作時需要注意的(de)(de)(de)問題很多，其中(zhong)較重(zhong)要的(de)(de)(de)是干(gan)(gan)式變(bian)(bian)(bian)壓(ya)(ya)(ya)器的(de)(de)(de)電(dian)(dian)流和電(dian)(dian)壓(ya)(ya)(ya)，需要認(ren)真了(le)解。干(gan)(gan)式變(bian)(bian)(bian)壓(ya)(ya)(ya)器的(de)(de)(de)電(dian)(dian)壓(ya)(ya)(ya)分(fen)布方式多樣，大(da)小電(dian)(dian)壓(ya)(ya)(ya)控制著整體運行，甚至在電(dian)(dian)路中(zhong)起著重(zhong)要作用。干(gan)(gan)式變(bian)(bian)(bian)壓(ya)(ya)(ya)器的(de)(de)(de)電(dian)(dian)壓(ya)(ya)(ya)分(fen)布在干(gan)(gan)式變(bian)(bian)(bian)壓(ya)(ya)(ya)器的(de)(de)(de)整個主體上，是穩(wen)定干(gan)(gan)式變(bian)(bian)(bian)壓(ya)(ya)(ya)器性(xing)能的(de)(de)(de)主要因素(su)。干(gan)(gan)式變(bian)(bian)(bian)壓(ya)(ya)(ya)器的(de)(de)(de)電(dian)(dian)壓(ya)(ya)(ya)分(fen)配是科學合理的(de)(de)(de)，所以干(gan)(gan)式變(bian)(bian)(bian)壓(ya)(ya)(ya)器的(de)(de)(de)電(dian)(dian)壓(ya)(ya)(ya)分(fen)配也是一個不(bu)可忽(hu)視(shi)的(de)(de)(de)環節。

變(bian)(bian)(bian)頻器的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)磁(ci)設計(ji)(ji)干(gan)(gan)(gan)式(shi)(shi)變(bian)(bian)(bian)壓(ya)器的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)磁(ci)設計(ji)(ji)根據招標文件和(he)(he)合(he)同協議(yi)中規定(ding)的(de)(de)(de)(de)產(chan)品技術和(he)(he)性(xing)能參(can)數進行，確定(ding)產(chan)品的(de)(de)(de)(de)主要尺寸和(he)(he)電(dian)(dian)(dian)(dian)磁(ci)負荷。短(duan)(duan)路(lu)阻(zu)(zu)抗計(ji)(ji)算短(duan)(duan)路(lu)阻(zu)(zu)抗是干(gan)(gan)(gan)式(shi)(shi)變(bian)(bian)(bian)壓(ya)器的(de)(de)(de)(de)一個重要性(xing)能參(can)數，它決定(ding)了干(gan)(gan)(gan)式(shi)(shi)變(bian)(bian)(bian)壓(ya)器在負載條件下的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)壓(ya)變(bian)(bian)(bian)化(hua)和(he)(he)短(duan)(duan)路(lu)時的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)流大小，也是干(gan)(gan)(gan)式(shi)(shi)變(bian)(bian)(bian)壓(ya)器并聯運(yun)行的(de)(de)(de)(de)條件。因此，準(zhun)確計(ji)(ji)算干(gan)(gan)(gan)式(shi)(shi)變(bian)(bian)(bian)壓(ya)器的(de)(de)(de)(de)短(duan)(duan)路(lu)阻(zu)(zu)抗具有重要意義。線(xian)圈短(duan)(duan)路(lu)強度的(de)(de)(de)(de)計(ji)(ji)算在大型干(gan)(gan)(gan)式(shi)(shi)變(bian)(bian)(bian)壓(ya)器中，短(duan)(duan)路(lu)電(dian)(dian)(dian)(dian)流是額定(ding)電(dian)(dian)(dian)(dian)流的(de)(de)(de)(de)8-10倍。由(you)于短(duan)(duan)路(lu)力與短(duan)(duan)路(lu)電(dian)(dian)(dian)(dian)流的(de)(de)(de)(de)平(ping)方成正比，在短(duan)(duan)路(lu)繞組的(de)(de)(de)(de)漏磁(ci)場和(he)(he)匝間電(dian)(dian)(dian)(dian)流的(de)(de)(de)(de)相互(hu)作用下，會在繞組的(de)(de)(de)(de)匝上施加很大的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)動(dong)勢，繞組結構可(ke)能永久變(bian)(bian)(bian)形(xing)損壞(huai)。

此(ci)外，導線絕(jue)(jue)緣(yuan)與繞(rao)組其他部分(fen)的(de)相對(dui)位(wei)移(yi)可能會(hui)損壞絕(jue)(jue)緣(yuan)，導致(zhi)匝間短(duan)(duan)路(lu)，因(yin)(yin)此(ci)準(zhun)確計算(suan)短(duan)(duan)路(lu)時(shi)線圈(quan)的(de)應(ying)力(li)具有重要意(yi)義。線圈(quan)短(duan)(duan)路(lu)強度(du)的(de)計算(suan)主要是計算(suan)干式(shi)(shi)變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)短(duan)(duan)路(lu)情況(kuang)下(xia)線圈(quan)各(ge)段應(ying)力(li)的(de)大(da)小和分(fen)布(bu)，檢查線圈(quan)的(de)機(ji)械強度(du)是否滿(man)足要求(qiu)。線圈(quan)沖(chong)擊電壓(ya)(ya)(ya)分(fen)布(bu)的(de)計算(suan)大(da)型干式(shi)(shi)變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)對(dui)絕(jue)(jue)緣(yuan)要求(qiu)較高(gao)，因(yin)(yin)此(ci)有必要了解干式(shi)(shi)變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)的(de)電壓(ya)(ya)(ya)分(fen)布(bu)，以(yi)便進(jin)行絕(jue)(jue)緣(yuan)設計。干式(shi)(shi)變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)允許的(de)連續工(gong)作電壓(ya)(ya)(ya)不得超過額定電壓(ya)(ya)(ya)的(de)5%，變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)運(yun)(yun)行中可能會(hui)出(chu)現過電壓(ya)(ya)(ya)，主要是由于運(yun)(yun)行故障(zhang)或雷(lei)擊造成的(de)。

干(gan)(gan)式(shi)變壓(ya)(ya)器(qi)的(de)電壓(ya)(ya)分(fen)配過程如上。要從整體(ti)上把握干(gan)(gan)式(shi)變壓(ya)(ya)器(qi)的(de)電壓(ya)(ya)分(fen)布，才能掌握干(gan)(gan)式(shi)變壓(ya)(ya)器(qi)的(de)電壓(ya)(ya)控制和運行規(gui)律(lv)。你知道(dao)干(gan)(gan)式(shi)變壓(ya)(ya)器(qi)的(de)作用(yong)嗎(ma)？如果(guo)你不(bu)知道(dao)，請關(guan)注我(wo)們(men)干(gan)(gan)式(shi)變壓(ya)(ya)器(qi)的(de)知識部(bu)分(fen)。
