Zithini iilahleko zeTransformer?

Ukulahleka kwe-power transformer kubandakanya ikakhulu ukulahleka kobhedu kunye nokulahleka kwentsimbi. Oku kungenxa yokuba naziphi na izixhobo zombane ziya kuvelisa ilahleko ngexesha elide lokusebenza, kwaye ii-power transformers azikho ngaphandle.

Yintoni umonakalo wesinyithi?

Ngokungafaniyo nokulahleka kobhedu, ukulahleka kwesinyithi kwetransformer akuxhomekekanga kwizinto ezifana nokujika kunye nobukhulu bangoku. Ngokwembono yegama, ukonakala kwesinyithi kunxulumene kakhulu nesinyithi, kuveliswa yintsimbi engundoqo. Ukulahleka kwesinyithi kwetransformer kwaziwa ngokuba "kukulahleka komthwalo", oku kungenxa yokuba ukulahleka kwesinyithi kuhlala kukho kwitransformer, nokuba ngumthwalo opheleleyo okanye umthwalo ongekhoyo, kwaye kuxhomekeke ekulahlekelweni okusisigxina kwetransformer. Nangona kunjalo, ngexesha lenkqubo yomthwalo, ukulahleka kwamandla kuya kuncipha ngokuncipha kwamandla ombane.

Uhlu lokulahleka kwesinyithi se-transformer

Ukulahleka kwesinyithi kwe-transformer kwahlulwe ngokulahleka kwe-hysteresis kunye nokulahleka komsinga we-eddy.

Ukulahleka kweHysteresis

Umgaqo osebenzayo we-transformer usekelwe kumgaqo wokungeniswa kwe-electromagnetic ukuze kufikelelwe ekunyukeni nasekuweni kwe-voltage kunye notshintsho lwangoku. I-magnetic flux kwi-transformer ihamba kwi-iron core. I-iron core inokumelana ne-magnetic flux, kanye njengokuba umqhubi enokumelana nombane. Ngokufanayo, ubushushu buya kuvela, kwaye olu lahleko lubizwa ngokuba yi-"hysteresis loss".

Ukulahleka kwangoku kuka-Eddy

Xa umsinga usetyenziswa kwi-primary winding ye-transformer, i-magnetic flux eveliswa yi-coil ingena kwi-iron core. Ngenxa yokuba i-core ngokwayo iyi-conductor, i-electrical potential ibangelwa kwi-plane ethe nkqo kumgca we-magnetic field. Le potential idala i-closed loop kwicandelo elinqamlezileyo le-core, nto leyo evelisa umsinga wombane. Lo msinga usebenza njenge-rotary vortex, yiyo loo nto igama elithi "vortex". Ukulahleka okubangelwa yi-eddy current kubizwa ngokuba yi-"eddy current loss". Kungenxa yokuba i-core idala i-eddy currents ukuze yenziwe ibe yi-thin sheet. Ngenxa yokuba i-core incinci, kokukhona i-resistance iphezulu, kokukhona i-current iphantsi.

Izinto ezibangela ukulahleka kwesinyithi se-transformer

• I-voltage yokusebenza kunye ne-frequency: Ukulahleka kwe-iron kunxulumene ne-voltage yokusebenza kunye ne-frequency ye-transformer kuba ezi zinto zichaphazela amandla e-magnetic field kunye ne-hysteresis embindini.
• Izinto ezingundoqo: Iimpawu ze-hysteresis zezinto ezingundoqo ziya kuchaphazela ubukhulu bokulahleka kwesinyithi. Ukuba izinto ezingundoqo azikhethwanga kakuhle, ukulahleka kwe-hysteresis kuya kwanda.
• Inkqubo yokuvelisa: Inkqubo yokuvelisa ye-transformer ikwanefuthe elithile ekulahlekeni kwesinyithi. Umzekelo, indlela ye-core lamination, unyango lwe-insulation, njl.njl. ziya kuchaphazela ubungakanani bokulahleka kwesinyithi.

Indlela yokunciphisa ukulahleka kwesinyithi se-transformer？

• Khetha izinto ezisemgangathweni ophezulu zentsimbi: Ukukhetha izinto ezisemgangathweni zentsimbi ezinokulahleka okuncinci kwe-hysteresis kunokunciphisa ukulahleka kwentsimbi ye-transformer.
• Lungiselela inkqubo yokuvelisa: Nciphisa ukulahleka kwesinyithi ngokuphucula indlela ye-core lamination, unyango lwe-insulation kunye nezinye iinkqubo zokuvelisa.
• Uyilo olufanelekileyo: Kwinqanaba loyilo lwe-transformer, ukulahleka kwesinyithi kuyancitshiswa ngokuphucula uyilo lwesakhiwo kunye nokukhethwa kweeparameter.

Ukulahleka kobhedu

I-Copper idlala indima ebalulekileyo kwii-transformers. Iintambo ze-Copper zihlala zisetyenziswa kwii-windings zee-transformers. "Ukulahleka kwe-copper" kwi-transformer kukulahleka okubangelwa ziintambo ze-copper. "Ukulahleka kwe-copper" ye-transformer kukwabizwa ngokuba kukulahlekelwa ngumthwalo. Oko kubizwa ngokuba kukulahlekelwa ngumthwalo kukulahlekelwa okuguquguqukayo kunye notshintsho.

Iyatshintsha ngotshintsho lwamandla ombane, ukulahleka kobhedu (ukulahlekelwa ngumthwalo) kukulahlekelwa okuguqukayo, kwaye kukwayilahleko ephambili ekusebenzeni kwe-transformer.

Izinto ezibangela ukulahleka kobhedu lwe-transformer

• Ubungakanani bangoku: Njengoko kukhankanyiwe apha ngasentla, ukulahleka kobhedu kuhambelana nesikwere sangoku, ngoko ke ubukhulu bangoku yeyona nto iphambili echaphazela ukulahleka kobhedu.
• Ukumelana nokujika: Ukumelana nokujika kuchaphazela ngokuthe ngqo ukulahleka kobhedu. Okukhona ukumelana kukhulu, kokukhona ukulahleka kobhedu kuphezulu.
• Inani leeleya zekhoyili: Okukhona iileya zekhoyili zininzi, kokukhona indlela yamandla ombane iqhubeka ixesha elide xa ejikeleza, kwaye ukumelana kuya kwanda ngokufanelekileyo, nto leyo ekhokelela ekulahlekelweni kobhedu okwandileyo.
• Ukutshintsha rhoqo: Isiphumo sokutshintsha rhoqo xa utshintsha ubhedu kwilahleko yobhedu yetransformer sinxulumene ngokuthe ngqo neeparamitha zokusasazwa kunye neempawu zomthwalo wetransformer. Xa iimpawu zomthwalo kunye neeparamitha zokusasazwa zivuselela, ukulahleka kobhedu kuyehla njengoko ukuguquguquka rhoqo kusanda; xa zinamandla, ukulahleka kobhedu kuyenyuka njengoko ukuguquguquka rhoqo kuyanda.
• Impembelelo yobushushu: Ukulahleka komthwalo kukwachaphazeleka bubushushu betransformer. Kwangaxeshanye, ukuvuza okubangelwa ngumsinga womthwalo kuya kubangela ilahleko yomsinga we-eddy kwi-winding kunye nelahleko ezilahlekileyo kwiindawo zesinyithi ezingaphandle kwe-winding.

Ungayinciphisa njani ilahleko yobhedu lwe-transformer?

• Yandisa indawo ejikelezayo yetransformer: nciphisa ukumelana nomqhubi, ngaloo ndlela unciphise ngempumelelo ukulahleka kobhedu kwetransformer.
• Sebenzisa izixhobo zomqhubi ezikumgangatho ophezulu: ezifana nefoyile yobhedu okanye ifoyile ye-aluminium ukunciphisa ukumelana nokujika.
• Nciphisa ixesha lokusebenza komthwalo olula wetransformer: Ukunciphisa umlinganiselo wexesha lokusebenza komthwalo olula wetransformer kuya kunceda ukunciphisa ukulahleka kobhedu kwetransformer.
