Iyini imiphumela yokuwa kwe-transformer core?

Umdali wokuqala: Ukukhanya Kwamadivayisi

Ekuhlolweni kwefektri kwama-transformer, ama-core amaningi kamagnetic e-transformer anamabhulokhi angekho ngenxa yomthelela wamaqhubu noma ukucindezelwa kwe-fixture. Iyini imiphumela yokuwa kwe-core ye-transformer? Lesi sihloko sizoxoxa ngokuqukethwe okufanele.
Siyazi ukuthi kuma-transformer, umsebenzi oyinhloko we-magnetic core ukuhlinzeka ngesekethe ye-magnetic, okuvumela i-transformer ukuthi idlulise amandla ngempumelelo. Lokhu kungabonakala kahle futhi efomini yokubala ye-inductance:

Ngokuvamile, sibheka ukuvuleka komoya njengo-1, kuyilapho ukuvuleka kwama-cores kazibuthe kungafinyelela phansi njengamashumi, kanti amaningi angafinyelela ezinkulungwaneni noma ngisho namashumi ezinkulungwane.
Kusukela kulo mbono, ama-transformer anama-core amagnetic akhulisa kakhulu i-inductance yawo, futhi amandla agciniwe futhi adluliselwayo nawo angakhuliswa ngokufanele. Ukusebenza kahle kokudluliselwa kwawo kuzothuthukiswa ngezinga elithile.
Ngaphezu kwalokho, umongo we-transformer unomthelela othile wokusekela isakhiwo kuwo wonke umkhiqizo we-transformer, okusiza ukugcina ukuzinza kwe-transformer nokunciphisa umsindo nokudlidliza.

Uma kukhona ibhulokhi elingekho ku-core transformer, kuzothinta ukudluliswa okuvamile kwesekethe kamagnetic. Ngemva kokuba i-core kamagnetic ingekho, ingxenye yokuqala ye-core kamagnetic iba umoya, okuholela ekwandeni kokumelana kukamagnetic, ukwehla kokusebenza kahle, futhi ezimweni ezimbi kakhulu, ukwehla kokungena, okusongela ngqo ukusebenza okuvamile komshini wonke.
Amanye ama-transformer nawo anezinhlayiya zamagnetic ezingekho. Ngesikhathi sokusebenza isikhathi eside komshini wonke, imifantu emincane ngaphakathi komgogodla wamagnetic (ingxenye engakawi ebhulokini) iyashesha futhi ikhule, okuholela ekulahlekelweni okukhulu kanye nokwenyuka kwezinga lokushisa kwe-transformer yonke, okuholela ekwehlulekeni komshini.

Kusukela kulo mbono, ukuntuleka kwamabhulokhi e-magnetic core kuma-transformer akuthinti nje kuphela ukusebenza, kodwa futhi kunomthelela ekusebenzeni nasekuthembekeni kwama-transformer. Njengamanje, amazinga okubukeka kwama-magnetic core chip abakhiqizi abaningi yilawa: indawo ye-chipping eyodwa akufanele idlule u-3% wendawo yonke yobuso be-magnetic core, futhi indawo yama-chipping amabili noma ngaphezulu akufanele idlule u-5%.
Abanye abakhiqizi nabo banomehluko othile, ongeke uchazwe lapha. Ingqikithi umehluko emingceleni yokuklama phakathi kwabakhiqizi, okuholela ezindinganisweni zokulawula ezahlukene.

Uma kuqhathaniswa nezindinganiso, sikholelwa ukuthi isizathu sokuwa kwe-transformer core sibaluleke kakhulu. Ikakhulukazi ngaphansi kwethonya lamandla angaphandle, akugcini nje ngokuthi ubuso be-transformer core bungawa, kodwa futhi bungabangela imifantu ngaphakathi kwe-transformer core, futhi ingozi ayikwazi ukuhlolwa kalula.
Kulokhu, ukuvela kokuphuka kwe-magnetic core ku-transformer kufaneleke kakhulu ukunakwa nokukhathalelwa kwethu.
