Isingeniso Se-Transformer Core Classification

1. Uhlobo Lwe-High-Frequency: Ama-Ferrite Cores

Ama-Ferrite cores asetshenziswa kuma-high-frequency transformers. Zingamamagnethi e-ceramic anesakhiwo sekristalu ye-spinel, esakhiwe nge-iron oxide nezinye izinhlanganisela zensimbi ezihlukene, njenge-kFe₂O₄ (lapho 'k' imelela ezinye izinsimbi). Izinsimbi ezisetshenziswayo njengamanje zifaka i-manganese (Mn), i-zinc (Zn), i-nickel (Ni), i-magnesium (Mg), nethusi (Cu).

Inhlanganisela evamile ihlanganisa uchungechunge lwe-manganese-zinc (MnZn), uchungechunge lwe-nickel-zinc (NiZn), kanye nochungechunge lwe-magnesium-zinc (MgZn). Lezi zinto zinokungena kazibuthe okuphezulu kanye nezindawo zokuvimba, ezinobubanzi befrikhwensi yokusebenza ukusuka ku-1 kHz ukuya ngaphezulu kuka-200 kHz.

2. Uhlobo lwe-Low-Frequency: I-Silicon Steel Laminations

Amashidi ensimbi ye-silicon asetshenziswa kuma-low-frequency transformers. Ziza ngezinhlobo ezahlukene futhi zingahlukaniswa ngezindlela ezimbili eziyinhloko:

• Ngenqubo yokukhiqiza: A: Anealed (amashidi amnyama) kanye no-N: Angafakwanga (amashidi amhlophe).

• Ngomumo: uhlobo lwe-EI, uhlobo lwe-UI, uhlobo lwe-C, kanye nama-cores (uhlobo lomlomo).

Amashidi ensimbi ye-silicon yohlobo lwesikwele avame ukusetshenziswa kuma-transformer anamandla amakhulu (imvamisa engaphezu kuka-500-1000 W). Banikeza ukufakwa kwe-insulation okuhle kakhulu, ukuchithwa kokushisa okulula, kanye nendlela emfushane kazibuthe. Isethi eyakhiwe ngamashidi amabili ensimbi ye-silicon ebizwa ngokuthi i-CD-type core. Kuma-transformer kagesi enziwe ngama-CD-type cores of the same cross-sectional area, iwindi elide livumela isilinganiso esikhulu samandla. Njengoba amakhoyili angafakwa ngokuhlukene ezinhlangothini zombili zomgogodla, ukujika okuphelele kungasatshalaliswa kuma-bobbin amabili. Lokhu kunciphisa ubude obumaphakathi bokujika nge-bobbin ngayinye futhi kunciphisa ukulahlekelwa kwethusi. Ukwengeza, ukusonga amakhoyili amabili alinganayo kuma-bobbins ahlukene kufeza ukulinganisa okuphelele.

Isethi eyakhiwe ngamashidi ensimbi ensimbi ye-C yohlobo lwe-C yaziwa ngokuthi i-ED-type core. Ama-transformer enziwe nge-ED-type cores anephrofayili emfushane, ebanzi uma kuqhathaniswa nama-CD-transformer wesilinganiso samandla esifanayo. Ngenxa yokuthi amakhoyili afakwe phakathi nendawo emaphakathi nendlela kazibuthe yangaphandle, iziguquli zohlobo lwe-ED zibonisa ukuvuza okuphansi kazibuthe nokuphazanyiswa okuncane. Kodwa-ke, njengoba wonke amakhoyili enziwe kwi-bobbin eyodwa, ewugqinsi, ubude bokujika buba yinde, okuholela ekulahlekeni okukhulu kwethusi.

Ama-cores ohlobo lwe-C anikeza ukusebenza okuhle kakhulu, okwenza ama-transformer angumphumela ahlangane, angasindi, futhi asebenze kahle kakhulu. Ngokombono wokuhlanganisa, ama-cores ohlobo lwe-C adinga izingxenye ezimbalwa kakhulu futhi anikeza ukuguquguquka okunamandla, okuholela ekusebenzeni kahle kokukhiqiza. Kodwa-ke, inqubo yokukhiqiza amashidi ensimbi ye-C-silicon iyinkimbinkimbi futhi idinga imishini ekhethekile, okwenza izindleko zabo zokukhiqiza zamanje zibe phezulu.

Amashidi ensimbi ensimbi yohlobo lwe-E, aziwa nangokuthi ama-cores ohlobo lwegobolondo, anenzuzo enkulu yokubeka amakhoyili ayisisekelo nawesibili ku-bobbin efanayo, anikeza isici sesikhala sefasitela esiphezulu (I-Space Factor Km: isilinganiso sendawo enetha yengxenye enqamulayo yocingo lwethusi endaweni yewindi). Amashidi ensimbi ye-silicon enza igobolondo elivikelayo elizungeze ama-windings, avimbele ukulimala komshini. Baphinde banikeze indawo enkulu yokukhipha ukushisa futhi banciphise imisebe yamagnetic field. Kodwa-ke, lo mklamo uholela ekungeneni kokuvuza okuphezulu okusuka kwesisekelo kuya kwesesibili kanye nokuba sengozini enkulu ekuphazamisekeni kwenkundla kazibuthe yangaphandle. Ngaphezu kwalokho, ngenxa yesiyingi esimaphakathi esimazombezombe eside, iziguquli zohlobo lwe-EI zidinga intambo yethusi eyengeziwe ngenani elifanayo lokujika kanye nendawo ephambanayo ewumgogodla.

Ugqinsi oluvame kakhulu lwamashidi ensimbi ye-silicon yi-0.35 mm no-0.5 mm.

Kunezindlela ezimbili zokuhlanganisa amashidi ensimbi ye-silicon: i-interleaving kanye ne-butting. Indlela ye-interleaving ishintshanisa ukuvuleka kwamashidi ezinhlangothini zombili. Nakuba le ndlela inzima, inciphisa izikhala kanye nokungabaza kazibuthe phakathi kwamashidi, okusiza ukwandisa i-magnetic flux; ngakho-ke, isetshenziswa kakhulu kuma-transformer amandla. Indlela ye-butting ivame ukusetshenziswa ezinhlelweni ezine-direct current (DC). Ukuvimbela ukugcwala okubangelwa i-DC, igebe kufanele lishiywe phakathi kwamashidi. Kule ndlela, ama-E-pieces kanye ne-I-pieces abekwe ezinhlangothini eziphambene, futhi igebe phakathi kwabo lingalungiswa ngokusebenzisa ama-shims ephepha.

3. Izinhlobo zamakhoyili

Amakhoyili ohlobo lwekhoyili ahlukaniswe abe izigaba ezintathu eziyinhloko:
A. I-Toroidal Core: Yenziwe ngokupakisha ama-laminations amise okwe-O noma imicu yensimbi ye-silicon esongelwayo. Ukugoqa lezi zinhlamvu kuyinselele impela.
B. I-Rod Core: Izinhlamvu kazibuthe ezimise okwenduku.
C. Drum Core: Izinhlamvu kazibuthe ezimise okwesigubhu.
