Iyini impendulo yefrikhwensi yama-transformer winding?

I-Transformer winding deformation ibhekisela ezinguqukweni ezingenakuhlehliswa kusayizi kanye nokuma kwesimo sokusonga ngaphansi kwesenzo semishini nogesi.Kuhlanganisa izinguquko kubukhulu be-axial kanye ne-radial, ukususwa komzimba, i-twist ephendukayo, i-bulging kanye ne-inter-turn shorts, njll. Isizathu siwukuthi i-transformer nakanjani kufanele imelane nokushaqeka kwe-short-circuit kanye nama-short-circuits endaweni yokuphuma ngesikhathi sokusebenza.Ikakhulukazi eyingozi kuma-transformer.

Nakuba i-circuit breaker ingakwazi ukuqeda ngokushesha iphutha le-short-circuit ku-circuit, idivayisi ezenzakalelayo ngokuvamile ayisebenzi ngesizathu esithile, ukuze ikhoyili ye-transformer ikhubazekile ngesikhathi esifushane kakhulu ngaphansi kwesenzo se-short-circuit current. ukushisa, ugesi, ngisho ne-interphase short-circuit engathí sina futhi I-winding ishile;ngesikhathi esifanayo, i-transformer ingase iphinde iqhume futhi ibe nomthelela ngesikhathi sokuthutha nokufakwa, okuholela ekuguqulweni, izintambo eziphukile, ukufuduka, ukuxegiswa nezinye izenzakalo.

Iyini inhloso yokuhlolwa kwe-deformation ye-transformer winding?

IMPENDULO: Ukuguqulwa kwamawindi kuyingozi enkulu efihliwe ekusebenzeni okuphephile kwezinhlelo zamandla.Eminyakeni yamuva nje, ngokwanda komthamo wesistimu kagesi, umthamo we-short-circuit nawo uyakhula, kanye nengozi yokulimala okumazombezombe ebangelwa ukufinyela kolayini ophumayo nayo iyakhula.

Ngemuva kokuthi i-transformer winding ikhubazekile, okokuqala ukuguqulwa kwebanga le-insulation noma ukulimala kwephepha lokufakelwa.Lapho i-overvoltage ihlangabezana, ama-windings azoba ne-inter-cake noma i-inter-turn breakdown, noma ngaphansi kwesenzo se-voltage yokusebenza yesikhathi eside, umonakalo we-insulation uzokhula kancane kancane, ekugcineni uholele ku-transformer.Ukulimala: Okwesibili, ngemva kokuba i-winging ikhubazekile, izakhiwo zemishini ziyancipha.Uma kwenzeka ingozi yesifunda esifushane futhi, ngenxa yokuthi ayikwazi ukumelana namandla omthelela omkhulu, ingozi yomonakalo esheshayo izokwenzeka, futhi isengasebenza isikhathi esithile.

I-Transformer winding deformation ingenye yezizathu ezibalulekile zokulimala kwe-transformer.Ukuhlola okujwayelekile kukagesi okufana nesilinganiso sokumelana, ukulinganisa isilinganiso sokuguqulwa, nesilinganiso somthamo kunzima ukuthola ukuwohloka okumazombezombe, okuzosongela kakhulu ukusebenza okuphephile kwegridi yamandla.Ngenxa yalesi sizathu, kudingekile kakhulu ukuthola nokuxilonga ukuguqulwa kwe-transformer windings ngaphansi kwamandla kagesi kanye nemishini.
