Kodi phokoso likuchokera pati pa thiransifoma?

Phokoso la thiransifoma limachokera mkati mwa thiransifoma. Transformer imachokera pa mfundo ya kulowetsedwa kwa electromagnetic, yokhala ndi koyilo yokhotakhota yam'mbali ndi yachiwiri yokhotakhota yomwe imayikidwa mkati, ndi pepala lachitsulo la silicon lomwe lili ndi maginito apamwamba kwambiri pakati. Zikhalidwe, ma coil windings a thiransifoma amawerengedwa molingana ndi gawo lapakati lapakati.

Popeza pali mapindikidwe a koyilo, ikalumikizidwa ndi magetsi a AC 50Hz, pamakhala phokoso losangalatsa.Mu AC koyilo pachimake, pali mbali ziwiri za kutayika, kutayika kosinthika ndikutayika kwafupipafupi, ndiko kuti, kutayika kwa mkuwa, kumagawidwanso magawo awiri, gawo lamphamvu yogwira ndi gawo lamphamvu.

"Eddy current" iyi imawonjezera kutayika kwa transformer ndikuwotcha pachimake cha transformer, kukweza kutentha kwa transformer.

Pali kutaya kwa mkuwa RI ² pa kukana kwa koyilo R ndi kutayika kwa chitsulo (kutayika kwa hysteresis ndi kutayika kwa eddy panopa) pakatikati pachitsulo.Kutayika kwachitsulo kumakhala pafupifupi molingana ndi Bm ².Pamene mafupipafupi a magetsi akhazikitsidwa, kutayika kwachitsulo kwa koyilo kumayenderana ndi mphamvu yogwira ntchito. Malinga ndi lingaliro la kusinthasintha kosalekeza U=4.44fNBmS, Bm pakatikati ndi molingana ndi mphamvu yamagetsi yomwe imagwiritsidwa ntchito.Mwa kuyankhula kwina, kutayika kwachitsulo kumakhala kofanana ndi lalikulu lamagetsi ogwiritsidwa ntchito.

Transformer ikhoza kuweruza ntchitoyo molingana ndi phokoso la ntchito.Njirayi ndiyo kugwiritsa ntchito mapeto amodzi a ndodo yomvetsera pa tanka ya mafuta ya transformer, ndipo mapeto ena pafupi ndi khutu kuti amvetsere mosamala phokosolo.Ngati ndi phokoso losalekeza la "yuyu", zikutanthauza kuti transformer ikuyenda bwino.Ngati phokoso la "yuyu" ndilolemera kuposa nthawi zonse, yang'anani kutentha kwa magetsi, kutentha kwamakono ndi mafuta a transformer kuti muwone ngati chifukwa cha magetsi ochulukirapo kapena kudzaza, ngati sichoncho, makamaka chifukwa cha chitsulo chosasunthika.Mukamva phokoso la "squeak, squeak", fufuzani ngati pali flashover pamwamba pa casing.Pamene phokoso la "kung'ung'udza" limveka, pali kuwonongeka kwa kutsekemera kwa mkati.

Makhalidwe a Volt-ampere a AC kuzungulira koyilo yachitsulo

Kutayika kwapang'onopang'ono kumagawidwa m'magawo awiri: kutayika kwa mphamvu yogwira ntchito komanso kutaya mphamvu.Transformer mu yachiwiri lotseguka dera boma, choyambirira akadali ndi ena panopa, ndiyeno kuchulukitsidwa ndi pulayimale oveteredwa voteji adzakhala ndi mowa wina mphamvu, panopa amatchedwa palibe katundu panopa.Kutayika kwamphamvu kwamphamvu kumatanthawuza kutayika kwa hysteresis ndi kutayika kwa eddy panopa muzitsulo zachitsulo, zomwe nthawi zambiri zimafotokozedwa mu ndondomeko ya fakitale kapena lipoti loyesa la thiransifoma.Gawo lowonongeka la mphamvu yowonongeka ndi kutayika komwe kumachitika chifukwa cha chisangalalo chamakono, chomwe chiri pafupifupi chofanana ndi mphamvu zopanda katundu wa transformer ndipo chikhoza kuwerengedwa ndi ndondomeko yotsatirayi molingana ndi momwe palibe katundu wamakono.

Q₀=I₀ (%)/100Se

The Q₀mu chilinganizo chimatanthawuza kutayika kwamphamvu kwamphamvu pakutayika kopanda katundu, m'mayunitsi a kvar.

I₀ (%) imatanthawuza kuchuluka kwa thiransifoma yopanda katundu pakali pano.

S₀mlingo umatanthawuza mphamvu yovotera ya thiransifoma mu KVA.

Ntchito mfundo ya single-gawo thiransifoma

The yogwira gawo ndi imfa chifukwa cha kukana kwa mapiringidzo oyambirira ndi yachiwiri mapiringidzo a thiransifoma pamene akudutsa panopa, amene ali molingana ndi lalikulu la panopa, kotero kukula kwake zimadalira katundu ndi mphamvu chinthu cha thiransifoma.Gawo lowonongeka la mphamvu ndilowonongeka kwambiri chifukwa cha kutuluka kwa mpweya, komwe kungathe kuwerengedwa ndi ndondomeko yotsatirayi.

Qd=Ud (%)/100Se

Qd mu fomula imatanthawuza kutayika kwamphamvu kwamphamvu kwa thiransifoma yaifupi-circuit kutayika, mu kvar mayunitsi.

Ud ndi kuchuluka kwa voteji yaifupi-circuit kuti ikhale voteji;

Se amatanthauza kuchuluka kwa thiransifoma mu kvA.
