Iyini i-Ferrite Core Transformer?

Ama-Ferrite core transformers ziyingxenye ebalulekile ezintweni eziningi zikagesi neze-elekthronikhi, ezihlinzeka ngokudluliswa kwamandla okuphumelelayo kanye nokuhlukaniswa kukagesi. Lezi ziguquli ze-ferrite zisetshenziswa kabanzi ezinhlelweni ezahlukahlukene, kusukela kumandla kagesi nama-inverter kuya kumishini yezokuxhumana nezinhlelo zomsindo. Izici ezihlukile zama-ferrite core transformers zibenza bafiseleke kakhulu kubuchwepheshe besimanje, banikeze izinzuzo ezinjengosayizi ohlangene, ukusebenza kahle okuphezulu, namandla amahle kakhulu okucindezela umsindo. Kulesi sihloko, sizohlola okuyisisekelo kwama-ferrite core transformers, ukwakhiwa kwawo, izimiso zokusebenza, kanye nokusetshenziswa.

Izisekelo zeFerrite Core Transformers

I-ferrite core transformer iwuhlobo lwedivayisi kagesi edlulisa amandla kagesi phakathi kwamasekethe amabili noma ngaphezulu ngokungeniswa kwe-electromagnetic. Iqukethe ukujikajika okuyinhloko, ukujika kwesibili, kanye nengqikithi kazibuthe eyenziwe ngezinto ze-ferrite. I-wing eyinhloko ixhunywe kumthombo we-voltage wokufaka, kuyilapho ukuphenduka kwesibili kuxhunywe kumthwalo ophumayo. Ama-winding ayisisekelo nawesibili ahlukene ngokomzimba kodwa ahlanganiswe ngozibuthe ngomongo we-ferrite, okuvumela ukudluliswa kwamandla ukusuka kwesisekelo kuya kwesesibili.

Ama-Ferrite core transformers anikeza izinzuzo ezimbalwa ngaphezu kwama-transformer anezinye izinto eziyinhloko ze-transformer. I-Ferrite ngokwayo iyinhlanganisela ye-ceramic eyenziwe ngokuyinhloko nge-iron oxide (Fe2O3), ehlanganiswe namanye ama-oxide ensimbi. Lokhu kwakheka kubangela izici zayo ezifiselekayo zikazibuthe, njengokufinyeleleka kukazibuthe okuphezulu, ukulahleka kwamanje kwe-eddy ephansi, nokumelana nogesi okuphezulu. Izici ezihlukile ze-ferrite ziyenza ifaneleke kahle izinhlelo zokusebenza zemvamisa ephezulu, lapho ikhombisa khona ukulahlekelwa kukazibuthe okuncane kanye nokugcwaliswa kwengqikithi.

Izinhlobo zeFerrite Core Transformers

1. I-Nickel Zinc (NiZn): Ine-resistivity ephakeme uma iqhathaniswa ne-MnZn ferrite. Asetshenziswa ezinhlelweni zikagesi lapho imvamisa iba phakathi kuka-2 MHz kuya kumakhulu amaningana e-MHz futhi afanele ama-inductors angaphezu kuka-70 Mhz. 

2. I-Manganese Zinc (MnZn): Anamazinga aphezulu okugcwala kanye nokungeneka okuphezulu kune-NiZn ferrite. Lezi zilungele izinhlelo zokusebenza ezinemvamisa yokusebenza engaphansi kuka-5MHz. Futhi, i-impedance yabo ibenza balungele ama-inductors afika ku-70 MHz.

3. Lamination/ Amorphous & I-Nanocrystalline: Ama-lamination transformer asetshenziswa ngokuyinhloko kuma-inverters, amasethi we-welding, kanye ne-UPS. 

4. Uthuli Lwesihlabathi: Lawa amakhoyili e-Choke anemvamisa ephezulu asetshenziswa nama-ferrites kuphela.

Ukwakhiwa kwamaFerrite Core Transformers

Ama-Ferrite core transformers anokwakhiwa okulula uma kuqhathaniswa nezinye izinhlobo ze-ferrite transformer. Ingqikithi ngokwayo ivamise ukuba yi-toroidal (i-donut-shaped) noma i-E-I-shaped, kuye ngezidingo ezithile zohlelo lokusebenza. Umnyombo wakhiwe ngokunqwabelanisa izingqimba eziningi ezincane noma ama-laminations ezinto ezivundile, ezimbozwe ngongqimba oluvikelayo ukuze kuncishiswe ama-eddy currents. Idizayini ewumgogodla we-laminated ithuthukisa ngokwengeziwe ukusebenza kahle kwe-transformer futhi yehlise nokulahlekelwa.

Ama-winding ayisisekelo kanye nesesibili alindiwe azungeze umnyombo we-ferrite, okuqinisekisa izinga eliphezulu lokuhlangana kazibuthe phakathi kwawo. Womabili ama-windinging ahlanganisa intambo yethusi evalekile, nenani lokujika ngakunye elinqunywa isilinganiso se-voltage esifunekayo. I-mangongo eyinhloko ngokuvamile inokushintshana okuningi kunamajika esibili, okuvumela ukuguqulwa kwe-voltage yokukhuphuka noma eyehlayo.

Izimiso Zokusebenza zamaFerrite Core Transformers

Ama-Ferrite core transformers asebenza ngokususelwe ezimisweni zokungeniswa kwe-electromagnetic. Uma i-alternating current (AC) igeleza endaweni yokujika eyinhloko, ikhiqiza inkambu kazibuthe eshintshanayo kumongo we-ferrite. Lo mkhakha uzibuthe ube usungenisa i-voltage kumajika esibili, ngokulingana nesilinganiso sokujika phakathi kwama-winding. I-polarity ye-voltage ebangelwe incike ekuqondeni kwendawo kazibuthe kanye nokucushwa kwamajika.

Ukusebenza kahle kuwukucatshangelwa okubalulekile ku umklamo we-ferrite transformer, kanye nama-ferrite core transformers ahamba phambili kulesi sici. Ukungena kazibuthe okuphezulu kwe-ferrite kuvumela ukuhlangana okusebenzayo kazibuthe phakathi kwama-windings, kunciphisa ukulahleka kwamandla ngesikhathi senqubo yokudlulisa. Ukulahlekelwa kwamanje okuphansi kwe-ferrite kuthuthukisa ukusebenza kahle, kunciphisa ukuchithwa kwamandla njengokushisa futhi kukhulise ukudluliswa kwamandla.

Izinzuzo zamaFerrite Core Transformers
