Uma i-transformer core ibekwe ndawonye, ​​yiziphi izindlela zomthungo? Uma i-transformer core ibekwe ndawonye, ​​iyini i-seam

■ Imibono ehlobene nomongo wensimbi

(1) Indawo enqamulayo yejometri: ibhekisela endaweni enqamulayo yesikhala esithathwe yinhliziyo yensimbi.

(2) Indawo ephumelelayo yokuhlukanisa izingxenye: ibhekisela endaweni yangempela yokuhlukanisa izingxenye zeshidi lensimbi ye-silicon etholwe ngokususa igebe phakathi kwamashidi ensimbi ye-silicon nendawo ehlalwa ukujiya kwefilimu yopende evikela ukufudumala endaweni yokuhlukanisa izingxenye yejometri.

(3) I-Lamination coefficient: ibhekisela kusilinganiso sendawo ephumelelayo ye-cross-section ye-core nendawo ye-geometric cross-section. I-lamination factor ihlobene nobukhulu kanye nokuthamba kweshidi lensimbi ye-silicon kanye nobukhulu besendlalelo sokuvikela phakathi kwamashidi. Isibonelo, uma kusetshenziswa ishidi lensimbi ye-silicon eliwugqinsi olungu-0.35mm, i-lamination factor ngokuvamile iphakathi kuka-0.91-0.96.

(4) I-coefficient yokugcwalisa: eyaziwa nangokuthi i-coefficient yokusetshenziswa, ibhekisela kusilinganiso sendawo enqamula ikholomu yensimbi eyakhiwe ngesimo sesitebhisi nendawo yendilinga yekholomu yenhloko. Ngaphansi kobubanzi obuthile, lapho indawo enqamula ikholomu yenhloko inkulu, okungukuthi, lapho inani lezinyathelo liba liningi, yilapho isici sokugcwalisa siba sikhulu. Kodwa-ke, lapho kunezinyathelo eziningi, kulapho imininingwane eminingi ye-laminations iba miningi, okwenza inqubo yokukhiqiza yenhloko ibe nzima.

■ Indlela yomthungo weshidi lensimbi ye-silicon

Uma i-transformer core ibekwe ndawonye, ​​kunezindlela ezintathu ezilandelayo zokuthunga amashidi ensimbi ye-silicon.

Umthungo oqondile - weshidi lensimbi ye-silicon eligoqiwe elishisayo kuphela

Njengoba kuboniswe kuMfanekiso 1. Izici zayo ukuthi ukucubungula kanye ne-lamination kulula kakhulu, futhi indawo ehambisanayo inkulu, ngakho-ke i-iron core ene-laminated inamandla amahle esakhiwo, ubuqotho obuqinile, futhi akulula ukuyishintsha, kodwa ingasetshenziswa kuphela kumashidi ensimbi e-silicon ashisiwe. Uma isetshenziselwa amashidi ensimbi e-silicon aqondiswe ebandayo anezakhiwo ezinhle ze-magnetic eceleni kwendlela yokugoqa, njengoba i-magnetic flux emthungweni ingadluli eceleni kwendlela yokugoqa, izakhiwo ze-magnetic zizowohloka, okuholela ekwandeni kokulahlekelwa okungenamthwalo.

Izihlanganisi eziqondile nezingama-semi-miter - zamashidi ensimbi e-silicon aqoqwe ngokubandayo

njengoba kuboniswe esithombeni 2. Isetshenziselwa ishidi lensimbi ye-silicon eligoqwe ngokusanhlamvu okubandayo. Isici salolu hlobo lomthungo ukuthi umthungo oqondile nomthungo we-miter zivela ngokushintshana ku-core lamination. Lapho ububanzi beshidi lekholomu eliyinhloko kanye neshidi le-iron joke kufana, umthungo we-miter ungama-45°. Ama-50% amakhona, izakhiwo zikagesi zithuthukiswa kakhulu uma kuqhathaniswa nemithungo eqondile, isakhiwo sithembekile, ukugunda nokubeka izinto nakho kulula, futhi izinga lokusetshenziswa kwamashidi ensimbi ye-silicon liphezulu. Kodwa-ke, ngoba kusekhona ingxenye yomthungo oqondile, ukuqondiswa kweshidi lensimbi ye-silicon eligoqwe ngokusanhlamvu okubandayo akukasetshenziswa ngokugcwele, ngakho-ke ukulahlekelwa yi-iron core okungenamthwalo akukwazi ukuncishiswa.

Umthungo we-miter ogcwele - weshidi lensimbi ye-silicon eligoqiwe eliqondiswe kokusanhlamvu okubandayo

Njengoba kuboniswe kuMfanekiso 3. Ukuze kuncishiswe kakhulu ukulahlekelwa kwe-iron core okungenamthwalo futhi kusetshenziswe ngokugcwele izici ze-cold-rolled oriented silicon steel sheet, kufanele kusetshenziswe ama-full oblique joints, ukuze isiqondiso se-magnetic flux sihambisane nesiqondiso sokugoqa se-silicon steel sheet, futhi ukulahlekelwa kwe-core kuncishiswe. Kodwa-ke, lolu hlobo lwenqubo yomthungo luyinkimbinkimbi, futhi ubuqotho be-stacked iron core abulungile.
