I-cores ye-transformer yangoku idlala indima ebalulekileyo ekusebenzeni kunye nokusebenza kweli candelo lombane elibalulekileyo. Ukuqonda iintlobo ezahlukeneyo zee-cores kunye neempawu zazo ziyimfuneko kuye nabani na osebenza nabaguquli bangoku okanye ojonge ukufunda ngakumbi malunga nabo. Kweli nqaku, siza kungena kwihlabathi lee-cores ze-transformer zangoku, sijonge iintlobo zazo, izixhobo kunye nokusetyenziswa kwazo. Masiqale uhambo lwethu ukuya entliziyweni yeenguqu zangoku.

Iindidi zeCores

Ii-cores zangoku ze-transformer ziza kwiindidi ezahlukeneyo, nganye ineempawu zayo ezizodwa kunye nokusetyenziswa kwayo. Iindidi ezimbini eziphambili ze-cores ziyi-toroidal kunye ne-nxeba core.

I-Toroidal cores i-donut-shaped kwaye iqulethe i-ring-shaped magnetic material. Ziyaziwa ngokusebenza kwazo okuphezulu kunye nokuvuza kwemagnethi ephantsi, okuzenza zilungele usetyenziso oluchanekileyo. I-Toroidal cores isetyenziswa ngokuqhelekileyo kwi-metering kunye nezicelo zokukhusela ngenxa yokusebenza kwazo okugqwesileyo kunye nobukhulu obuncinci.

Ngakolunye uhlangothi, amanxeba amanxeba aquka imagnethi enenxeba okanye elekwe. Ezi core zisebenza ngeendlela ezininzi kwaye zinokuyilwa ukuhlangabezana neemfuno ezithile zesicelo. Amanxeba amanxeba ahlala esetyenziswa kwi-high-voltage kunye ne-high-current applications ngenxa yokwakhiwa kwawo okuqinileyo kunye nokukwazi ukuphatha ubuninzi bamandla. Uyilo lwabo luvumela ulawulo oluchanekileyo kwiimpawu zamagnetic, ezibenza zilungele uluhlu olubanzi lwezicelo ze-transformer zangoku.

Izinto ezisetyenziswa kwiiCores

Izinto ezisetyenziswayo kwii-cores ze-transformer zangoku zidlala indima ebalulekileyo ekusebenzeni kwazo kunye neempawu zamagnetic. Izinto ezingundoqo eziqhelekileyo ziquka intsimbi ye-silicon, i-nickel, kunye ne-ferrite.

Intsimbi ye-silicon yenye yezona zinto zisetyenziswa kakhulu kwii-cores ze-transformer zangoku ngenxa yokungena kwayo kwimagnethi kunye nelahleko ephantsi. Iyaziwa ngeempawu zayo zemagneti ezigqwesileyo, eziyenza ifaneleke kwizicelo ezichanekileyo. Iintsimbi zensimbi ze-silicon zibonelela ngoxinaniso oluphezulu lwe-saturation flux kunye ne-hysteresis ephantsi, ezenza zilungele imilinganiselo echanekileyo yangoku.

I-nickel cores isetyenziswa rhoqo kwi-high-frequency kunye ne-high-temperature applications. Banikezela ngeempawu ezintle zamagnetic kwi-frequencies ephezulu kwaye banokusingatha iimeko zokusebenza ezigqithisileyo. I-nickel cores isetyenziswa ngokuqhelekileyo kumandla ombane kunye neenkqubo zamandla ahlaziyekayo apho imilinganiselo yangoku ephezulu iyimfuneko.

I-Ferrite cores ithandwa kakhulu kwi-low-frequency kunye ne-low-power applications. Banikezela ukuchasana okuphezulu kwi-demagnetization kwaye balungele usetyenziso apho ubungakanani kunye nobunzima zizinto ezibalulekileyo. Iicores zeFerrite ziqhele ukusetyenziswa kwiisekethe zombane, unxibelelwano, kunye nezicelo zokulinganisa amandla aphantsi ngenxa yeempawu zazo ezibalaseleyo zemagneti kunye nokusebenza kakuhle kweendleko.

Iimpawu zeCores

Ii-cores zangoku ze-transformer zibonisa iimpawu ezahlukeneyo ezimisela ukusebenza kwazo kunye nokufaneleka kwezicelo ezahlukeneyo. Ezinye zeempawu eziphambili zibandakanya ukufikeleleka kwamagnetic, ukuxinana kwe-saturation flux, kunye nokulahleka okungundoqo.

Ukungena kwemagneti ngumlinganiselo wesakhono semathiriyeli ukuxhasa ukuyilwa kwemagnethi ngaphakathi kwayo. Izixhobo ezinobuchwephesha obuphezulu obunamandla ziyakwazi ukugxila ngokufanelekileyo kwi-flux yamagnetic, ekhokelela ekusebenzeni okuphezulu kwe-transformer kunye nokuchaneka. Ngokomzekelo, ii-Toroidal cores zaziwa ngokungena kwazo kwimagnethi ephezulu, nto leyo ezenza zilungele imilinganiselo yangoku echanekileyo.

Uxinaniso lwesaturation flux lubhekiselele kubuninzi bomthamo wemagnethi enokuxhaswa yimathiriyeli phambi kokufikelela kwisatuation. IiCores ezinoxinzelelo oluphezulu lwe-saturation flux zinokuphatha imisinga emikhulu ngaphandle kokulahlekelwa kukuchaneka. Olu phawu lubalulekile kwizicelo zangoku eziphezulu apho imilinganiselo echanekileyo ibalulekile.

Ilahleko engundoqo, ekwabizwa ngokuba yilahleko yentsimbi, sisixa samandla esichithwe njengobushushu ngaphakathi kwezinto ezingundoqo ngenxa ye-hysteresis kunye nelahleko yangoku ye-eddy. Ilahleko ephantsi engundoqo ibalulekile ekugcineni ukuchaneka kunye nokusebenza kakuhle kweziguquli zangoku. Iintsimbi zensimbi ze-silicon, umzekelo, zibonisa ilahleko ephantsi, ezenza zifaneleke kwizicelo ezichanekileyo.
