Kwihlabathi lobunjineli bombane, ii-transformers zidlala indima ebalulekileyo ekuqinisekiseni ukusasazwa kwamandla ngokufanelekileyo nangokukhuselekileyo. Ezi zixhobo zibalulekileyo zinoxanduva lokunyusa okanye ukunciphisa amanqanaba e-voltage, zivumela umbane ukuba udluliselwe kumgama omde kwaye usetyenziswe kwizicelo ezahlukeneyo. Umbindi we-transformer yinxalenye ebalulekileyo echaza ukusebenza kwayo kunye nokusebenza kwayo ngokubanzi. Kweli nqaku, siza kujonga kwiintlobo ezahlukeneyo zee-transformer cores kwaye sihlolisise impembelelo yazo ekusebenzeni kwezi matshini zibalulekileyo.

Iitransformer zineendlela ezimbini ezahlukeneyo zokujikajika, ezaziwa ngokuba zii-primary windings kunye nee-secondary windings, ezahlulwe nge-elektroniki yi-core. I-core isebenza njengendlela yemagnethi yokujika okubangelwa yi-primary winding, nto leyo ebangela i-voltage efunekayo kwi-secondary winding. Ukukhethwa kwezinto eziphambili kuchaphazela kakhulu ukusebenza kakuhle, ubungakanani, kunye neendleko ze-transformer. Makhe sihlolisise iintlobo ezahlukeneyo zee-transformer cores size siqonde iimpawu zazo ezahlukeneyo:

IiCores zeMagnetic

Ii-magnetic cores zisetyenziswa kakhulu kwii-transformers ngenxa yeempawu zazo ezintle ze-magnetic. Ezi cores zihlala zenziwe ngezinto ze-ferromagnetic ezifana nentsimbi okanye intsimbi, ezinendawo ephezulu yokungena kwe-magnetic. Ii-magnetic cores zibonelela ngendlela ye-magnetic evaliweyo, eqinisekisa unxibelelwano oluphezulu lwe-flux phakathi kwee-windings eziphambili nezesibini. Olu nxibelelwano oluphuculweyo lwe-flux luguqulela ekuphuculeni ukusebenza kakuhle kokudluliselwa kwamandla. Ii-magnetic cores zikwanciphisa imiphumo ye-snacks magnetic fields, zonyusa ukusebenza ngokubanzi kwe-transformer.

Ii-iron cores zisetyenziswa kakhulu kwii-power transformers, apho ukusebenza kakuhle okuphezulu kunye nokulahleka kwamandla aphantsi kubaluleke kakhulu. Ukusetyenziswa kwee-iron cores ezifakwe i-laminated kunciphisa ngakumbi ukulahleka kwamandla ngokunciphisa i-eddy currents ngaphakathi kwezinto eziphambili. Ii-iron cores, kwelinye icala, zikhethwa kwiindawo apho kufuneka khona ukusebenza kwamaza aphezulu, njengakwii-audio transformers.

IiFerrite Cores

Ii-ferrite cores zisetyenziswa kakhulu kwii-high-frequency transformers ngenxa yeempawu zazo ezizodwa zemagnethi. Ezi cores zenziwe ngomxube wesinyithi kunye nee-metal oxides ezahlukeneyo, nto leyo ebangela ukuba izinto zibe nokumelana okuphezulu kombane kunye nokulahleka kombane okuphantsi. Ii-ferrite cores zibonelela ngokusebenza okuphezulu kwii-frequency eziphezulu, nto leyo ezenza zifaneleke kwizicelo ezifana nezixhobo zombane ze-switch-mode, unxibelelwano, kunye nee-radio frequency transformers (RF).

Ngenxa yokumelana kwazo okuphezulu, ii-ferrite cores zibonisa ukulahleka okuphantsi kwe-hysteresis xa kuthelekiswa nee-magnetic counterparts zazo. Ukongeza, ii-ferrite cores zinokubunjwa zibe ziimo ezintsonkothileyo, okuvumela uyilo lwe-transformer oluncinci nolukhaphukhaphu. Nangona kunjalo, ii-ferrite cores azilungele ukusetyenziswa kwee-frequency eziphantsi, njengoko ukungena kwazo kuncipha kakhulu kwii-frequency eziphantsi.

IiCores eziLaminated

Ii-laminated cores zisetyenziswa kakhulu kwii-transformers ezisebenza kwii-voltage eziphezulu kunye nee-frequency. Ezi cores zakhiwe ngokubeka iileya ezincinci zezinto ze-ferromagnetic, ngokuqhelekileyo i-silicon steel okanye i-nickel-iron alloys. Iileya nganye nganye zigqunywe ngombane, nto leyo enciphisa imiphumo ye-eddy currents enokwenzeka kwizinto eziqinileyo.

Inkqubo yokulamina inciphisa kakhulu ilahleko yamandla e-eddy kunye ne-magnetic hysteresis, nto leyo ekhokelela ekuphuculweni kokusebenza kakuhle kunye nokunciphisa ubushushu. Ii-laminated cores zisetyenziswa kakhulu kwiitransformer zokuhambisa umbane kunye nokusasazwa kwamandla, kunye nakwiindlela ezahlukeneyo zokusebenza kwemizi-mveliso.

IiToroidal Cores

Ii-cores zeToroidal zibonelela ngeenzuzo ezikhethekileyo kuyilo lwe-transformer, ngokuyintloko ngenxa yejometri yazo efana nedonathi. Ezi cores, ezenziwe nge-strip ye-silicon steel wound zibe yi-closed loop, zinezinga eliphezulu lokulingana kwemagnethi kunye nokuvuza okuncitshisiweyo kwemagnethi. Ukungabikho kwezithuba zomoya kwii-cores ze-toroidal kubangela ukuxhathisa okuphantsi kwemagnethi kunye nokusebenza ngcono kokudluliselwa kwamandla.

Imilo emincinci yee-toroidal cores ivumela ubungakanani obuphantsi kunye nobunzima kwiindlela zokuguqula ii-transformer ngelixa zibonelela ngokhuseleko oluhle kakhulu lwemagnethi. Ii-Toroidal transformers zifumaneka rhoqo kwizixhobo ze-elektroniki ezifana nee-amplifiers zesandi, izixhobo zamandla, kunye nezixhobo zombane apho ubukhulu kunye nobunzima zizinto ezibalulekileyo ekufuneka ziqwalaselwe.

IiCores zoMoya

Ngokungafaniyo nee-magnetic cores, ii-air cores azisebenzisi naziphi na izinto ze-ferromagnetic ekwakheni kwazo. Endaweni yoko, ezi cores zixhomekeke emoyeni ojikelezileyo njengesixhobo esiphambili se-magnetic. Ii-air cores zibonelela ngenzuzo yokulahleka kwamandla phantse akukho kunye nemiphumo ye-hysteresis engaphantsi. Nangona kunjalo, ii-air cores zine-inductance ephantsi kakhulu xa kuthelekiswa nee-magnetic cores zazo.

Ii-air-core transformers zifumana ukusetyenziswa kwiisekethe zerediyo (RF), apho kufuneka khona ukusebenza kwe-high-frequency, kwaye nayiphi na into ye-ferromagnetic ingazisa ilahleko engafunekiyo. Ukungena kwazo okuphantsi kuzenza zingafaneleki ukusetyenziswa kokusasazwa kwamandla apho kubandakanyeka khona ii-voltages eziphezulu kunye nemisinga.

Isishwankathelo
