Zithini iilahleko zeTransformer?

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 kwentsimbi kunxulumene nevolthi yokusebenza kunye nokuphindaphinda kwetransformer kuba ezi zinto zichaphazela amandla emagnethi kunye ne-hysteresis embindini.
• Izinto eziphambili:Iimpawu ze-hysteresis zezinto eziphambili ziya kuchaphazela ubukhulu bokulahleka kwesinyithi. Ukuba izinto eziphambili azikhethwanga kakuhle, ukulahleka kwe-hysteresis kuya kwanda.
• Inkqubo yokuvelisa:Inkqubo yokwenziwa kwe-transformer nayo inempembelelo ethile 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 zentsimbi:Ukukhetha izinto ezingundoqo zesinyithi ezinokulahleka okuncinci kwe-hysteresis kunokunciphisa ukulahleka kwesinyithi kwe-transformer.
• Lungiselela inkqubo yokuvelisa:Nciphisa ukulahleka kwesinyithi ngokuphucula indlela yokugquma okuphambili, unyango lokufakelwa kwe-insulation kunye nezinye iinkqubo zokuvelisa.
• Uyilo olufanelekileyo:Kwinqanaba loyilo lwe-transformer, ukulahleka kwentsimbi 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 sombane, ngoko ke ubukhulu bombane yeyona nto iphambili echaphazela ukulahleka kombane.
• Ukumelana nokujika:Ukumelana nokujija kuchaphazela ngokuthe ngqo ukulahleka kobhedu. Okukhona uxhathiso lukhulu, kokukhona ukulahleka kobhedu kuphezulu.
• Inani leeleya zekhoyili:Okukhona kukho iileya zekhoyili ezininzi, kokukhona indlela yomsinga iqhubeka ixesha elide xa ujikeleza, kwaye ukumelana kuya kwanda ngokufanelekileyo, nto leyo ekhokelela ekulahlekelweni kobhedu okwandileyo.
• Ukutshintsha rhoqo:Isiphumo sokujika rhoqo kombane kwilahleko yobhedu lwetransformer sinxulumene ngokuthe ngqo neeparamitha zokusasazwa kunye neempawu zomthwalo wetransformer. Xa iimpawu zomthwalo kunye neeparamitha zokusasazwa zivuselela, ilahleko yobhedu iyancipha njengoko ifrequency yokutshintsha inyuka; xa zinamandla, ilahleko yobhedu iyanda njengoko ifrequency yokutshintsha inyuka.
• Impembelelo yobushushu:Ukulahleka komthwalo nako kuyachaphazeleka 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 ye-transformer:ukunciphisa ukumelana nomqhubi, ngaloo ndlela kunciphisa ngempumelelo ukulahleka kobhedu kwetransformer.
• Sebenzisa izixhobo zomqhubi ezikumgangatho ophezulu:njenge-copper foil okanye i-aluminium foil ukunciphisa ukumelana nokujika.
• Nciphisa ixesha lokusebenza komthwalo olula we-transformer:Ukunciphisa ixesha lokusebenza komthwalo olula we-transformer kuya kunceda ukunciphisa ukulahleka kobhedu kwe-transformer.
