Zithini iziphumo zokuwa kwe-transformer core?

Umdali wokuqala: Ukukhanya kwezixhobo

Kuhlolo lwefektri lwee-transformers, uninzi lwee-magnetic cores ze-transformer zinezithintelo ezingekhoyo ngenxa yempembelelo yeziphazamiso okanye ukucinezelwa kwezixhobo. Zithini iziphumo zokuwa kwe-transformer core? Eli nqaku liza kuxoxa ngomxholo ofanelekileyo.
Siyazi ukuba kwiitransformers, umsebenzi ophambili we-magnetic core kukubonelela ngesekethe yemagnethi, evumela itransformer ukuba idlulise amandla ngokufanelekileyo. Oku kunokubonakaliswa kakuhle kwifomyula yokubala ye-inductance:

Ngokubanzi, sicinga ukuba ukuvuleka komoya kufana no-1, ngelixa ukuvuleka kwee-magnetic cores kunokufikelela kumashumi, kwaye uninzi lunokufikelela kumawaka okanye kwanamashumi amawaka.
Ngokwale mbono, ii-transformers ezinee-magnetic cores ziyandisa kakhulu i-inductance yazo, kwaye amandla agciniweyo nadluliselwayo nawo anokwandiswa ngokufanelekileyo. Ukusebenza kakuhle kokudluliselwa kwazo kuya kuphuculwa ukuya kuthi ga kwinqanaba elithile.
Ukongeza, umongo we-transformer unempembelelo ethile yenkxaso yesakhiwo kuyo yonke imveliso ye-transformer, nto leyo enceda ukugcina uzinzo lwe-transformer kunye nokunciphisa ingxolo kunye nokungcangcazela.

Ukuba kukho ibhloko engekhoyo kwi-core transformer, oku kuya kuchaphazela ukuhanjiswa okuqhelekileyo kwesekethe ye-magnetic. Emva kokuba i-core ye-magnetic ilahlekile, inxalenye yokuqala ye-core ye-magnetic iba ngumoya, nto leyo ebangela ukwanda kokumelana kwe-magnetic, ukwehla kokusebenza kakuhle, kwaye kwiimeko ezinzima, ukwehla kokungena, nto leyo ebeka emngciphekweni ukusebenza okuqhelekileyo komatshini wonke.
Ezinye ii-transformer nazo zine-magnetic cores ezingekhoyo. Ngexesha lokusebenza ixesha elide komatshini wonke, ii-microcracks ngaphakathi kwe-magnetic core (inxalenye engawanga kwibhloko) ziyakhawuleza kwaye ziyanda, nto leyo ebangela ilahleko eyongezelelekileyo kunye nokunyuka kobushushu be-transformer yonke, nto leyo ekhokelela ekubeni umatshini ungasebenzi kakuhle.

Ngokwale mbono, ukungabikho kweebhloko ze-magnetic core kwii-transformers akuchaphazeli nje kuphela ukusebenza, kodwa kukwachaphazela ukusebenza kunye nokuthembeka kwee-transformers. Okwangoku, imigangatho yokubonakala kwe-magnetic core chipping yabenzi abaninzi yile: indawo ye-chipping enye akufuneki idlule kwi-3% yendawo yonke yomphezulu we-magnetic core, kwaye indawo ye-chipping ezimbini okanye ngaphezulu akufuneki idlule kwi-5%.
Abanye abavelisi nabo banomahluko, ongazukucaciswa apha. Eyona nto iphambili ngumahluko kwimida yoyilo phakathi kwabavelisi, nto leyo ekhokelela kwimigangatho eyahlukeneyo yolawulo.

Xa kuthelekiswa nemigangatho, sikholelwa ukuba isizathu sokuwa kwe-transformer core sibaluleke ngakumbi. Ingakumbi phantsi kwempembelelo yamandla angaphandle, akupheleli nje ekubeni umphezulu we-transformer core uwele, kodwa unokubangela imingxunya ngaphakathi kwe-transformer core, kwaye umngcipheko awunakuvavanywa nje.
Kule meko, ukwenzeka kokuqhekeka kwe-magnetic core kwi-transformer kufaneleke ngakumbi ukuba siqwalasele kwaye sixhalabele.
