Inxalenye ephambili yetransformer nganye yi-core yayo, esebenza njengendlela yokuhambisa i-magnetic flux. Izinto eziphambili ezisetyenziswa kwiitransformer zichaphazela ngokuthe ngqo ukusebenza kwazo, ukuthembeka, kunye nokusebenza kakuhle. Kweli nqaku, siza kujonga iimpawu zezinto eziphambili kwiitransformer, sixoxe ngeempawu zazo, iingenelo, iingxaki, kunye nokusetyenziswa kwazo ezahlukeneyo.

Ukubaluleka Kwezinto Eziphambili KwiTransformers

Izinto eziphambili ezisetyenziswa kwiitransformer zinoxanduva lokukhokela intsimi yemagnethi, eyenza kube lula ukudluliselwa kwamandla ombane. Zisebenza njengendlela yokuhamba kwemagnethi, zinciphisa ukulahleka kwamandla ngelixa ziqinisekisa ukuguqulwa kwamandla ngokufanelekileyo. Ukukhethwa kwezinto eziphambili kunefuthe elikhulu ekusebenzeni ngokubanzi kunye neempawu zetransformer.

Intsimbi kunye neNsimbi

Intsimbi kunye nentsimbi bezisoloko zizinto eziphambili zemveli kwiitransformer. Ezi zinto zine-magnetic permeability ephezulu, nto leyo evumela i-magnetic flux esebenzayo kwaye inciphisa ukulahleka kwamandla. Ukongeza, ii-iron kunye neentsimbi zinika amandla abalaseleyo oomatshini, okuvumela ukudluliselwa kwamandla amaninzi ngempumelelo. Zisetyenziswa kakhulu kwiitransformer zamandla, iitransformer ze-voltage ephezulu, kunye neetransformer zokusasaza.

Nangona kunjalo, ingxaki enkulu yeentsimbi zentsimbi kunye neentsimbi kukuba ziyakwazi ukulahleka ngenxa ye-eddy currents kunye ne-hysteresis. Ii-eddy currents zibangela ubushushu kwizinto eziphambili, nto leyo ebangela ukuchithwa kwamandla. Ukulahleka kwe-hysteresis kwenzeka ngenxa yokubambezeleka kwi-magnetization kunye ne-demagnetization yezinto xa zichatshazelwa yi-magnetic fields etshintshanayo. Ezi lahleko zinokunciphisa kakhulu ukusebenza kakuhle kwee-transformers.

IiFerrite Cores

Ii-ferrite cores zenziwe ngezinto ze-ceramic magnetic, ikakhulu ii-ferrites, eziluhlobo lwe-iron oxide. Zinokumelana okuphezulu kwi-eddy currents kwaye zibonelela ngeempawu ezintle ze-magnetic kwi-frequency ephezulu, nto leyo ezenza ukuba zilungele ukusetyenziswa njengee-inductors kunye nee-transformers ezisetyenziswa kwi-electronics yamandla. Ii-ferrite cores zihlala zisetyenziswa kwi-switch-mode power supplies, ii-audio transformers, kunye nee-radio frequency transformers.

Enye yeenzuzo eziphawulekayo zee-ferrite cores kukuba zibiza kancinci xa kuthelekiswa nezinye izinto eziphambili. Zikwabonisa iimpawu ezibalaseleyo ze-high-frequency, zibonelela ngokusebenza okuphezulu kwizicelo ezifuna ukutshintsha ngesantya esiphezulu. Nangona kunjalo, ii-ferrite cores zinoxinano oluphantsi lwe-saturation flux kunye ne-magnetic permeability xa kuthelekiswa nee-iron kunye ne-steel cores. Ke ngoko, azifanelekanga kwii-transformers ezinamandla aphezulu ezisebenza kwii-frequency eziphantsi.

IiCores eziLaminated

Ii-laminated cores, ezaziwa ngokuba zii-stacked cores, zakhiwa ngokubeka amaphepha amancinci okanye ii-lamination zesinyithi se-silicon. Ii-lamination zihlala zigqunywe ngobushushu ukuze kuthintelwe ukwenziwa kwee-eddy currents. Olu lungiselelo lunciphisa kakhulu ilahleko ze-eddy current, nto leyo eyenza ii-laminated cores zisebenze ngcono kunee-solid cores ezakhiwe ngentsimbi enye okanye ngentsimbi.

Ukufakwa kobushushu phakathi kwe-laminations kwenziwa ngeendlela ezahlukeneyo, kuquka i-varnish, ii-oxide layers, okanye iindawo ezigqunywe nge-coated surfaces. Ii-laminated cores zisetyenziswa kakhulu kwi-distribution transformers kunye ne-power transformers ezincinci ukuya kweziphakathi. Zibonelela ngelahleko ephantsi kwaye zisebenza kakhulu ekunciphiseni inkcitho yamandla.

Iintsimbi ze-Amorphous Metal Cores

Ii-Amorphous metal cores, ezaziwa ngokuba zii-metallic glass cores, zongezwa kutshanje kuluhlu lwezinto eziphambili. Zenziwe nge-alloy enesakhiwo esingesi-crystalline, nto leyo ebangela iipropati zemagnethi ezikhethekileyo. Ii-Amorphous metal cores zibonisa ilahleko ephantsi kakhulu kwi-core, nto leyo eyenza ukuba zisebenze kakuhle ekuguquleni amandla.

Ukulahleka okuphantsi kwe-core ye-amorphous metal cores kunokubangelwa kukungabikho kwe-magnetic domains kwisakhiwo sayo. Oku kususa i-hysteresis kwaye kunciphisa ukulahleka kwe-eddy current. Ukusetyenziswa kwe-amorphous metal cores kwi-transformers kunokukhokelela ekongeni amandla okukhulu kunye nokusebenza kakuhle okuphuculweyo.

Ii-cores zesinyithi ezi-Amorphous zifumana ukusetyenziswa kwii-transformers ezahlukeneyo, kuquka ii-power transformers, ii-distribution transformers, kunye nee-current transformers. Nangona kunjalo, ukusetyenziswa kwazo ngokubanzi kuthintelwa yindleko zazo eziphezulu xa kuthelekiswa nezinye izinto eziphambili. Nangona kunjalo, uphando oluqhubekayo kunye nophuhliso lujolise ekwenzeni ii-cores zesinyithi ezi-amorphous zisebenze ngakumbi ngokwezoqoqosho, nto leyo enokuguqula ishishini le-transformer.

Isishwankathelo

Ukuqukumbela, ukukhethwa kwezinto eziphambili kudlala indima ebalulekileyo ekumiseleni ukusebenza kunye nokusebenza kakuhle kweetransformer. Iintsimbi zentsimbi kunye neentsimbi zisetyenziswa kakhulu kwizicelo ezininzi zetransformer, zibonelela ngokukhanya okuphezulu kunye namandla oomatshini. Iintsimbi zeFerrite zibonelela ngokusebenza okugqwesileyo kwiifrequensi eziphezulu kwaye zingabizi kakhulu, ngelixa iintsimbi ezilaminethiweyo kunye neentsimbi zesinyithi ezingabonakaliyo zibonelela ngokulahleka okuncitshisiweyo kombane we-eddy kunye nokusebenza ngcono.

Njengoko imfuno yokusebenzisa amandla kakuhle iqhubeka isanda, kulindeleke ukuba kubekho uphuhliso oluthe kratya kwizixhobo eziphambili. Uphando oluqhubekayo nophuhliso lujolise ekuphuculeni iimpawu zemagnethi kunye nokunciphisa iindleko zeentsimbi ezingenasimo, nto leyo ezenze zibe lukhetho olusebenzisekayo kwiitransformers. Ekugqibeleni, ukuqonda iimpawu zezinto eziphambili kunika abavelisi amandla okuyila nokuphuhlisa iitransformers ezihlangabezana neemfuno ezihlala zitshintsha zeshishini lombane.
