Transformer winding deformation - kusintha komweko

Kusintha kwa m'deralo kumatanthauza kuti kutalika kwa koyilo sikunasinthe, kapena kukula kofanana ndi makulidwe a koyilo sikunasinthe m'dera lalikulu;kukula kokha kagawidwe kofanana kwa makoyilo ena kwasintha, kapena kukula kofanana kwa makeke ena a koyilo kwasintha pang'ono.Chiwerengero chonsecho sichinasinthidwe, kotero ma curve a sipekitiramu a gawo lolakwika ndi gawo labwinobwino adzalumikizana pa nsonga iliyonse ya resonance mu band yotsika.Ndi kukula kwa gawo lopindika pang'ono, nsonga zofananira za resonance zidzachotsedwa.

Kuponderezana kwanuko ndi kutulutsa kotulutsa: Mtundu woterewu nthawi zambiri umadziwika kuti umayamba chifukwa cha mphamvu yamagetsi.Chifukwa cha mphamvu yothamangitsa yomwe imapangidwa ndi njira yomweyi mbali imodzi, pomwe malekezero awiri a koyiloyo akakanikizidwa, mphamvu yothamangitsa iyi imafinya mapepala amtundu uliwonse, zomwe zimapangitsa kuti Magawo amafinyidwa ndipo magawo amakokedwa.Kupindika kwamtunduwu nthawi zambiri sikukhudza waya wotsogolera ngati misomali yoponderezedwa mbali zonse ziwiri isasunthike: mawonekedwe amtunduwu nthawi zambiri amangosintha mtunda (axial) pakati pa mikateyo, ndipo mphamvu (pakati pa makeke) imawonekera. mu inductance yofanana mu gawo lofanana la capacitance) kusintha.Ndi zotsogola zomwe sizikukokedwa, gawo lafupipafupi la sipekitiramu lidzasintha pang'ono.Koyilo yonseyo sipanikizidwa, gawo limodzi lokha la mtunda pakati pa mikateyo limachotsedwa, ndipo mtunda wina pakati pa mikateyo umakanizidwa.Zitha kuwoneka kuchokera ku spectrogram kuti nsonga zina zowonongeka zimasunthira kumalo othamanga kwambiri ndi kuchepa kwa mtengo wapamwamba;pamene nsonga zina zomveka zimasunthira kumalo otsika pafupipafupi ndipo zimatsagana ndi kuwonjezeka kwa mtengo wapamwamba.Deformation deformation ndi mlingo wa deformation akhoza kuyesedwa ndi kufufuzidwa poyerekezera malo omwe nsonga ya resonance imasunthidwa mwachiwonekere, (chiwerengero cha nsonga) ndi kuchuluka kwa kusintha kwa resonance.Gawo lapamwamba la spectrogram lidzasintha pamene kuponderezana kwapafupi ndi kutulutsa kutuluka kumakhudza kutsogolera.Pamene mlingo wa psinjika m`deralo ndi kukoka-kunja mapindikidwe ndi lalikulu, ena resonance nsonga mu otsika pafupipafupi ndi pakati pafupipafupi magulu ali palimodzi, munthu nsonga kutha, ndi matalikidwe ena resonance nsonga ukuwonjezeka.
Kutembenuza kutembenuka kwafupikitsa: Ngati chitsulo cha inter-turn short circuit chichitika mu koyilo, kutsekemera konse kwa koyilo kumachepetsedwa kwambiri, ndipo kutsekedwa kwa koyilo ku chizindikiro kudzachepetsedwa kwambiri.Mogwirizana ndi spectrogram, nsonga yowoneka bwino ya band yotsika mwachiwonekere imasunthira kumayendedwe apamwamba kwambiri, ndipo nthawi yomweyo, chifukwa cha kuchepa kwa chopingacho, mayendedwe oyankha pafupipafupi amasunthira mbali yakuchepetsa kuchepa mu otsika pafupipafupi gulu, ndiye kuti, pamapindikira adzasunthira mmwamba ndi kuposa 2ddB;Kuonjezera apo, kusiyana pakati pa nsonga za resonance ndi zigwa pamphepete mwazitsulo zidzachepetsedwa chifukwa cha kuchepa kwa mtengo wa Q.Ma curve owoneka bwino apakati ndi ma frequency apamwamba amalumikizana ndi ma coil wamba.
Zingwe za koyilo zosweka: Zingwe za koyilo zikaduka, kukokera konse kwa koyilo kumawonjezeka pang'ono.Mogwirizana ndi spectrogram, nsonga ya resonant ya low-frequency band idzasuntha pang'ono kumalo otsika kwambiri, ndipo kutsika kwa matalikidwe kumakhalabe kosasintha;ma spectral curves apakati-ma frequency ndi apamwamba-frequency band amagwirizana ndi spectrogram ya coil wamba.
Chitsulo chachilendo chachilendo: Mu coil wamba, ngati pali chitsulo chakunja pakati pa mikateyo, ngakhale kuti sichimakhudza kwambiri kutsika kwafupipafupi kwafupipafupi, mphamvu pakati pa mikateyo idzawonjezeka.The resonance pachimake cha otsika pafupipafupi mbali ya sipekitiramu pamapindikira adzapita otsika pafupipafupi malangizo, ndi matalikidwe a pakati ndi mkulu pafupipafupi mbali ya pamapindikira adzawonjezeka.
Kusamuka kwa kutsogolera: Pamene chiwongolerocho chikuchotsedwa, sichimakhudza inductance, kotero kuti gulu lochepa lafupipafupi la spectrum curve liyenera kupitilizidwa kotheratu, ndipo chigawo chokhacho cha 2ookHz ~ 5ookHz chimasintha, makamaka ponena za matalikidwe ochepetsetsa.Waya wotsogolerawo akamalowera ku chipolopolo, mbali yotalikirapo ya nsonga ya sipekitiramu imayenda molowera komwe kumapangitsa kuti pakhale kutsika, ndipo mkhotolowo umatsika pansi;pamene waya wotsogolera akuyandikira pafupi ndi koyilo, mbali yafupipafupi ya spectrum curve imayenda motsatira njira yochepetsera kutsika, ndipo mpiringidzo umasunthira mmwamba.
Axial buckle: Axial kupindika ndikuti pansi pa mphamvu yamagetsi, koyiloyo imakankhidwira mbali zonse ziwiri.Ikakanikizidwa ndi malekezero onse awiri, imakakamizika kuti ipunduke kuchokera pakati.Ngati kusiyana kwa msonkhano wa thiransifoma wapachiyambi ndi kwakukulu kapena zomangira zimakakamizika kusuntha , koyiloyo imapotozedwa mu mawonekedwe a S mu njira ya axial;kupindika uku kumangosintha gawo la capacitance pakati pa mikate ndi gawo la capacitance pansi chifukwa malekezero awiriwo sasintha.The inter-screen capacitance ndi capacitance pansi zidzachepa, kotero resonant nsonga kusuntha kwa ma frequency apamwamba pa sipekitiramu pamapindikira, resonant pachimake pafupi otsika pafupipafupi adzatsika pang'ono, ndi resonant nsonga pafupipafupi pafupi mafupipafupi wapakatikati adzawuka. pang'ono, ndipo mafupipafupi a 3ookHz ~ 5ookHz adzawonjezeka pang'ono.Mizere yowoneka bwino imasunga chikhalidwe choyambirira.
Kupindika (diameter) kwa koyilo: Pansi pa mphamvu ya electrodynamic, coil yamkati nthawi zambiri imalumikizidwa mkati.Chifukwa cha kuchepa kwa kukhala kwamkati, koyiloyo ikhoza kukhala yopunduka mumayendedwe amplitude, ndipo m'mphepete mwake mumakhala zigzag.Kupindika kumeneku kudzapangitsa kuti inductance ichepetse pang'ono, mphamvu yapansi imasinthanso pang'ono, kotero nsonga ya resonance mumtundu wonse wafupipafupi imasuntha pang'ono kupita kumayendedwe apamwamba.The matalikidwe mapindikidwe a koyilo akunja makamaka kukula kwakunja, ndipo inductance okwana wa koyilo mapindikidwe adzawonjezeka, koma mtunda pakati pa koyilo wamkati ndi akunja adzawonjezeka, ndi capacitance wa waya keke pansi adzachepa.Choncho, nsonga yoyamba ya resonance ndi chigwa pamphepete mwazitsulo zidzasunthira kumalo otsika pafupipafupi, ndipo nsonga zotsatirazi ndi zigwa zidzasuntha pang'ono kupita kumayendedwe apamwamba.
