Xa i-transformer core ibekwe ndawonye, ​​zeziphi iindlela zomthungo? Xa i-transformer core ibekwe ndawonye, ​​zeziphi iindlela zomthungo

■ Iingcamango ezinxulumene nomongo wesinyithi

(1) Indawo enqamlezileyo yejometri: ibhekisa kwindawo enqamlezileyo yendawo ehlala umbindi wesinyithi.

(2) Indawo enqamlezileyo esebenzayo: ibhekisa kwindawo enqamlezileyo yeshiti yesinyithi yesilicon efunyenwe ngokususa umsantsa phakathi kwamaphepha esinyithi esilicon kunye nendawo ehlala ubukhulu befilimu yepeyinti yokukhusela kwindawo enqamlezileyo yejometri.

(3) I-Lamination coefficient: ibhekisa kumlinganiselo wendawo esebenzayo ye-cross-sectional ye-core ukuya kwindawo ye-geometric cross-sectional. I-lamination factor inxulumene nobukhulu kunye nokuthe tyaba kweshiti yesinyithi ye-silicon kunye nobukhulu bomaleko wokukhusela phakathi kwamaphepha. Umzekelo, xa kusetyenziswa ishiti yesinyithi ye-silicon enobukhulu obuyi-0.35mm, i-lamination factor ngokubanzi iphakathi kwe-0.91-0.96.

(4) I-filling coefficient: ekwaziwa ngokuba yi-useisure coefficient, ibhekisa kumlinganiselo wendawo enqamlezileyo yekholamu yentsimbi eyintloko eyenziwe ngesimo selidreyi ukuya kwindawo yesangqa sekholamu engundoqo. Phantsi kobubanzi obuthile, okukhona indawo enqamlezileyo yekholamu engundoqo inkulu, oko kukuthi, kokukhona inani lamanyathelo liphezulu, kokukhona into yokuzalisa inkulu. Nangona kunjalo, okukhona kukho amanyathelo amaninzi, kokukhona iinkcukacha ze-laminations zininzi, nto leyo eyenza kube nzima inkqubo yokwenziwa kwe-core.

■ Indlela yomthungo wephepha lesinyithi lesilicon

Xa i-transformer core ibekwe ndawonye, ​​kukho iindlela ezintathu ezilandelayo zokuthungela amaphepha esinyithi e-silicon.

Umthungo othe ngqo - kuphela wephepha lesinyithi lesilicon eligoqiweyo elishushu

Njengoko kubonisiwe kuMfanekiso 1. Iimpawu zayo zezokuba ukucubungula kunye nokulamination kulula, kwaye indawo edibeneyo inkulu, ngoko ke isiseko sesinyithi esilaminethiweyo sinamandla alungileyo olwakhiwo, ukuqina okuqinileyo, kwaye akulula ukusenza siguqulwe, kodwa sinokusetyenziswa kuphela kwiishiti zesinyithi zesilicon ezigoqwe ngobushushu. Ukuba isetyenziselwa iishiti zesinyithi zesilicon ezigoqwe ngobushushu ezineempawu ezintle zemagnethi ecaleni kwendlela yokuqengqeleka, ekubeni i-magnetic flux kumthungo ingadluli kwicala lokuqengqeleka, iimpawu zemagnethi ziya kuhla, nto leyo ebangela ukwanda kokulahleka komthwalo.

Izihlanganisi ezithe nkqo nezithe nkqo - zeeshiti zesinyithi zesilicon ezigoqwe zibandayo

njengoko kubonisiwe kumfanekiso 2. Isetyenziselwa iphepha lesinyithi lesilicon eligoqwe ngengqolowa ebandayo. Uphawu lolu hlobo lomthungo kukuba umthungo othe ngqo kunye nomthungo we-miter zibonakala ngokutshintshana kwi-core lamination. Xa ububanzi bephepha lekholamu eyintloko kunye nephepha le-iron joke zifana, umthungo we-miter ungama-45°. Ama-50% eekona, iipropati zemagnethi ziphucuke kakhulu xa kuthelekiswa nemithungo ethe ngqo, ulwakhiwo luthembekile, ukucheba kunye nokubeka izinto nazo zilula, kwaye izinga lokusetyenziswa kwamaphepha esinyithi esilicon liphezulu. Nangona kunjalo, ngenxa yokuba kusekho inxalenye yomthungo othe ngqo, indlela ebekwe ngayo iphepha lesinyithi lesilicon eligoqwe ngengqolowa ebandayo ayisetyenziswa ngokupheleleyo, ngoko ke ukulahleka komthwalo we-iron core akunakuncitshiswa.

Umthungo opheleleyo we-miter - wephepha lesinyithi le-silicon eligoqiweyo elijonge kwiinkozo ezibandayo

Njengoko kubonisiwe kuMfanekiso 3. Ukuze kuncitshiswe ngakumbi ukulahleka kwesiseko sentsimbi ngaphandle komthwalo kwaye kusetyenziswe ngokupheleleyo iimpawu zeshiti yesinyithi yesilicon ejikeleziweyo ebandayo, kufuneka kusetyenziswe amalungu apheleleyo a-oblique, ukuze ulwalathiso lwe-magnetic flux luhambelane nolwalathiso lweshiti yesinyithi yesilicon, kwaye ukulahleka kwesiseko kuncitshiswe. Nangona kunjalo, olu hlobo lwenkqubo yomthungo luyinkimbinkimbi, kwaye ukuthembeka kwesiseko sentsimbi ehlanganisiweyo kuphantsi.
