Yintoni i-transformer winding frequency response?

I-deformation ye-transformer winding ibhekisela kwiinguqu ezingenakukwazi ukuguqulwa kubukhulu kunye nokuma kwe-winging phantsi kwesenzo soomatshini kunye nombane.Ibandakanya utshintsho kwimilinganiselo ye-axial kunye ne-radial, ukufuduka komzimba, i-winding twist, i-bulging kunye ne-inter-turn shorts, njl.Ngokukodwa kuyingozi kwi-transformers.

Nangona i-breaker yesiphaluka inokuphelisa ngokukhawuleza i-short-circuit fault kwi-circuit, isixhobo esizenzekelayo sisoloko singasebenzi ngenxa yesizathu esithile, ukwenzela ukuba i-coil ye-transformer ikhubazeke ngexesha elifutshane kakhulu phantsi kwesenzo se-short-circuit current. ubushushu, umbane, kunye ne-interphase short-circuit enzulu kwaye Ukujija kutshisiwe;kwangaxeshanye, i-transformer inokungqubana kwaye ichaphazeleke ngexesha lothutho kunye nokufakwa, okukhokelela kwi-deformation, imicu eyaphukileyo, ukufuduka, ukukhulula kunye nezinye izinto.

Yintoni injongo yovavanyo lokuguquguquka kwe-transformer?

IMPENDULO: I-Winding deformation yingozi enkulu efihlakeleyo ekusebenzeni ngokukhuselekileyo kweenkqubo zamandla.Kwiminyaka yakutshanje, ngokunyuka komthamo wenkqubo yamandla, umthamo we-short-circuit nawo uyanda, kunye nengozi yomonakalo ojikelezayo obangelwa yi-short-circuit yomgca ophumayo nayo iyanda.

Emva kokuba i-transformer winding ikhubazekile, okokuqala kukutshintsha komgama we-insulation okanye umonakalo wephepha le-insulation.Xa i-overvoltage idibene, i-windings iya kuba ne-inter-cake okanye i-inter-turn breakdown, okanye phantsi kwesenzo se-voltage yokusebenza kwexesha elide, umonakalo we-insulation uya kwanda ngokuthe ngcembe, ekugqibeleni ukhokelela kwi-transformer.Umonakalo: Okwesibini, emva kokuba i-winging ikhubazekile, iimpawu zomatshini ziyancipha.Xa ingozi yesiphaluka esifutshane yenzeke kwakhona, ngenxa yokuba ayinako ukumelana namandla amakhulu empembelelo, ingozi yomonakalo okhawulezayo iya kwenzeka, kwaye isenokusebenza ixesha elithile.

I-deformation yokuguqula i-transformer yenye yezizathu ezibalulekileyo zomonakalo we-transformer.Iimvavanyo zombane eziqhelekileyo ezifana nomlinganiselo wokuchasa, umlinganiselo wenguqu, kunye nomlinganiselo we-capacitance kunzima ukufumana i-deformation ejikelezayo, eya kusongela kakhulu ukusebenza ngokukhuselekileyo kwegridi yamandla.Ngenxa yesi sizathu, kubaluleke kakhulu ukufumanisa kunye nokuxilongwa kwe-deformation ye-transformer windings exhomekeke kumandla omatshini kunye nombane.
