Uhlelo lokupholisa lwe-transformer yamandla luqukethe izingxenye ezimbili: uhlelo lokupholisa lwangaphakathi, oluqinisekisa ukuthi ukushisa kwe-winding kanye ne-iron core kuhlakazeka endaweni ezungezile; uhlelo lokupholisa lwangaphandle, oluqinisekisa ukuthi ukushisa okuphakathi kuhlakazeka ngaphandle kwe-transformer. Ngokusho kobukhulu bomthamo we-transformer, indawo kanye nohlobo lokujikeleza, i-transformer isebenzisa izindlela ezahlukene zokupholisa.

I-transformer iyithuluzi elingaguquki elisebenza njalo, elithembekile uma lisebenza futhi linamathuba amancane okwehluleka. Kodwa-ke, njengoba iningi lama-transformer lifakwe ngaphandle, futhi lithintwa umthwalo ngesikhathi sokusebenza kanye nephutha le-short-circuit yesistimu yamandla, amaphutha ahlukahlukene kanye nezimo ezingavamile zenzeka ngokungenakugwenywa ngesikhathi sokusebenza.

1. Iyini imiphumela yamaqembu ahlukene okuxhumana ekusebenzeni okufanayo kwama-transformer?
Impendulo: Uma ama-transformer amaqembu ahlukene okuxhumana esebenza ngokulingana, isekethe yesibili izokhiqiza umehluko we-voltage ngenxa yama-voltage ahlukene ohlangothini lwesibili lwama-transformer Δ U2, ngoba umehluko wesigaba esiphelele ekuxhumekeni kwe-transformer uyi-multiple ka-30 ° Δ Inani le-U2 likhulu. Uma umehluko we-engeli yesigaba sohlangothi lwesibili lwe-transformer ehambisanayo ingu-30 °, Δ Inani le-U2 lingu-51.76% we-voltage elinganiselwe. Uma i-voltage ye-short-circuit Uk ye-transformer ingu-5.5%, i-equalizing current ingafinyelela izikhathi ezingu-4.7 zamanje olinganiselwe, okungase kushise i-transformer.
Umehluko omkhulu wesigaba ukhiqiza ugesi omkhulu wokulinganisa, okungavunyelwe. Ngakho-ke, ama-transformer amaqembu ahlukene awakwazi ukusebenza ngesikhathi esifanayo.

Ngesikhathi sokwakha, i-transformer eyomile kanye ne-transformer yamafutha ingakhethwa ngokwesikhala. I-transformer yamafutha ingakhethwa uma isikhala sikhulu, kanti i-transformer eyomile ingakhethwa uma isikhala sigcwele.

1. Ukwehluleka kokuvala
Ngokuyinhloko kukhona i-inter-turn short circuit, i-winding grounding, i-phase-to-phase short circuit, i-wire breaking kanye ne-joint welding. Izizathu zalokhu kwehluleka yilezi ezilandelayo:
① Ngesikhathi sokukhiqiza noma sokulungisa, ukuvikela kwendawo kuyalimala, okushiya amaphutha;
② Ngenxa yokushabalaliswa kahle kokushisa noma ukulayisha ngokweqile isikhathi eside ngesikhathi sokusebenza, izinhlobo ezahlukene ze-dry ziwela ezimbotsheni, okubangela ukuthi izinga lokushisa libe phezulu kakhulu futhi ukufudumala kukhule;
③ Inqubo yokukhiqiza ayinhle, ukucindezela akuqinile, amandla omshini awakwazi ukumelana nokushayisana kwe-short-circuit, futhi ukugoqa kuyaphazamiseka futhi ukufudumala kuyalimala.

UMengameli waseRussia uVladimir Putin usayine umyalelo kusihlwa sangomhlaka-21 wokuhlonipha "iDonetsk People's Republic" kanye "neLuhansk People's Republic" empumalanga ye-Ukraine. Ngesikhathi sendawo sama-24, uMengameli waseRussia uVladimir Putin uthe enkulumweni ephuthumayo eboniswe kuthelevishini ukuthi unqume ukuqhuba umsebenzi wezempi okhethekile esifundeni saseDonbas.

Umugqa wokusika we-spacer wesivinini esikhulu
Umugqa wokusika ojikayo ubude

Umthamo wokuphuka kwamanje we-short-circuit we-low-voltage side circuit breaker ye-distribution transformer mncane kakhulu; ithonya lamanje lokuzinza kokushisa kwekhebula aliqinisekiswa ohlelweni lokusabalalisa lwamandla aphansi, okuholela endaweni encane enqamula ezinye izintambo zesekethe yokusabalalisa ohlelweni lokusabalalisa lwamandla aphansi.

I-CANWIN Isikhungo sokucubungula i-transformer core yesizukulwane sesithathu safakwa ekukhiqizweni njengoba kwakuhleliwe, futhi amasethi ayi-10 emishini eqediwe azofakwa kancane kancane emakethe!
Umshini wesizukulwane sesithathu usebenzisa indlela yokugunda eyodwa kanye nokushaya okune, okungukuthi, ukugunda okujiyile kusetshenziswa njengomshini oyinhloko wokugunda, ongasika ama-engeli angama-degree angu-45, ama-degree angu-90, kanye nama-degree angu-135, futhi ungashintsha i-engeli ngesikhathi sokugunda ngesivinini esikhulu;
Ama-punch amane abhekisela kumasethi amabili ama-punch anomumo ongu-V angahamba eceleni, kanye namasethi amabili ama-punch anomumo ongu-O angahamba eceleni nangemuva ngesikhathi esisodwa. Ukuhlanganiswa kwesenzo, isenzo esisodwa sesiqediwe!
Ithrekhi yomkhawulo weshidi lensimbi ye-silicon yomshini wesizukulwane sesithathu isebenzisa umklamo wethrekhi evulekile, kanti i-limit bearing isebenzisa i-ceramic bearing, okulula kakhulu ukuyihlanza nokuyisebenzisa;
Ngaphezu kwalokho, umshini wesizukulwane sesithathu usebenzisa i-magnetic belt tension feeder eklanywe ngokukhethekile yi-CANWIN, okuyinto engcono kakhulu ngemininingwane!

Njengamanje, wonke amazwe emhlabeni ngokuvamile asebenzisa imodi yokusabalalisa i-transformer core shearing, okuyindlela yesevisi ye-industrial chain ethuthukisiwe izwe lami eliye layinaka futhi lafunda kuyo. Eminyakeni yamuva nje, ngokuthuthukiswa kobuchwepheshe bokukhiqiza obuhlakaniphile bezwe lami, intuthuko yobuchwepheshe bokukhiqiza obuhlakaniphile be-transformer core kanye nokuqubuka kwe-coronary pneumonia entsha kukhuthaze kakhulu le ntuthuko.

Le vidiyo ikubonise ukuthi i-power transformer eyinhloko ibukeka kanjani.

Iqhutshwa ukusungula izinto ezintsha kwezesayensi nobuchwepheshe, i-Keying Electric ihola insimu ye-power transformer endaweni ejulile yamanzi esezingeni eliphezulu, ehlakaniphile futhi ekhiqiza ngezinga elikhulu.
