Zida zosiyanasiyana zapakhomo, mafakitalepafupipafupi thiransifoma, kaya adzipangira okha mapiringidzo, kapena kukonzanso thiransifoma yowotchedwa, akuphatikizidwa mu gawo la mawerengedwe osavuta, mabuku owerengera pa chilinganizo, ngakhale kuti ndi okhwima, koma ntchito zothandiza za zovuta, osati zosavuta kwambiri.Nkhaniyi ikuwonetsa kuwerengera kwa thiransifoma wa epirical formula.
1. Kusankha chitsulo pakati
Malinga ndi mphamvu zawo zofunika kusankha pachimake choyenera ndi sitepe yoyamba yokhotakhota thiransifoma. Ngati chitsulo pachimake (silicon zitsulo pepala) kusankha ndi lalikulu kwambiri, zidzachititsa kuwonjezeka kukula kwa thiransifoma, mtengo wapamwamba, koma pachimake chitsulo ndi laling'ono kwambiri, adzawonjezera imfa ya thiransifoma, pamene luso. kunyamula katundu amakhala osauka.
Kuti mudziwe kukula kwa chitsulo pakati, chinthu choyamba kuwerengera mphamvu yeniyeni ya thiransifoma yachiwiri, yomwe ili yofanana ndi thiransifoma yachiwiri yothamanga voteji, kuchuluka kwa katundu wa katundu panopa. Ngati ndi thiransifoma yowonjezereka, iyenera kuwerengedwa ngati 1/2 yamagetsi achiwiri. Sekondale mapiringidzo mphamvu kujowina thiransifoma palokha kutaya mphamvu, ndiye thiransifoma choyambirira zikuoneka mphamvu.
General yachiwiri yokhotakhota mphamvu mu 10w pansi pa thiransifoma, kutayika kwake kwa mphamvu yachiwiri kungakhale mpaka 30 ~ 50% ya mphamvu yeniyeni yogwiritsira ntchito mphamvu, mphamvu yake ndi 50 ~ 70% yokha. Mphamvu yachiwiri yokhotakhota mu 30 w pansi kutayika pafupifupi 20 ~ 30%, 50 w kutsika kutayika pafupifupi 15 ~ 20%, 100 w kutsika kutayika pafupifupi 10 ~ 15%, 100 w pamwamba pakutayika pafupifupi 10% pansipa, pamwambapa kutayika kwa parameter ndi za thiransifoma wamba wamba. Ngati dongosolo la mtundu wa R-transformer, c-type transformer ndi toroidal transformer likutsatiridwa, chizindikiro chotayika chimachepetsanso.
Malingana ndi mphamvu zonse zoyambirira za transformer yowerengedwa pamwamba pa pachimake ikhoza kusankhidwa. Chigawo chachitsulo S = axb (cm2). Monga momwe tawonetsera pachithunzichi. Mphamvu yowonekera ya Transformer ndi ubale pakati pa s ndi chilinganizo chotsatirachi: s = K √ P1
P1 ya thiransifoma yowoneka bwino yamphamvu, unit: VA (volt-ampere), s iyenera kusankhidwa pachimake chopingasa, K ndi coefficient, ndi kukula kwa chosinthira Pl kusankha kosiyanasiyana kwamitundu yosiyanasiyana. Pa nthawi yomweyi, poganizira pepala lachitsulo cha silicon pakati pa utoto wotetezera, zotsatira za kusiyana, K ndi P1 ubale ndi:
Mtengo wa P1K
10VA 2 - 2.2
50VA pansipa 2 ~ 1.5
lOOVA pansi pa 1.5 ~ 1.4
2. Kuwerengera matembenuzidwe pa volt
Pambuyo posankha pachimake s. Ndiye kudziwa chiwerengero cha mokhota pa volt, kuti mphepo thiransifoma ali wololera chisangalalo panopa. Zomwe zimagwiritsidwa ntchito kawirikawiri: N = (40 ~ 55)/S, N ndi chiwerengero cha kutembenuka pa volt.
Malinga ndi khalidwe losiyana la pakachitsulo zitsulo pepala kusankha koyefiyanti 40 ~ 55. apamwamba apamwamba pakachitsulo zitsulo, ndi diso kuona pamwamba pa mamba crystallization. Ndipo brittle kwambiri, nthawi 1 mpaka 2 yokha yomwe imasweka, yosweka mosagwirizana, coefficient imatengedwa ngati 40. Ngati pepala lachitsulo la silicon lili loyera, kupindika 4 mpaka 5 sikuli kosavuta kuthyoka, gawo lokonzekera bwino. mzere wowongoka, coefficient imatengedwa ngati yopitilira 50.
Dziwani kuchuluka kwa ma volt pa volt kuchulukitsidwa ndi 220V ndiko kutembenuka koyambirira, kuchulukitsidwa ndi kuchuluka kwa zofunikira zamagetsi achiwiri omwe ndi makhothi achiwiri. Chifukwa waya ali ndi kukana, kuthamanga kwaposachedwa kudzera pakutsika kwamagetsi, kutembenuka kwachiwiri kuyenera kukulitsidwa ndi 5 ~ lO% (malinga ndi kusankhidwa kwapakali pano, komweko kumatha kuonjezeredwa ndi gawo lalikulu).
3. Kusankhidwa kwa waya awiri
Malinga ndi kukula kwa mapindikidwe katundu panopa, kusankha diameters osiyana waya enameled. Njira yotsatilayi ingagwiritsidwe ntchito kuti mudziwe:
d=O.8√ine.
Chigawo: l – A. d (waya awiri) – mm.
4. Njira Zotsekera ndi Kusamala
Chifukwa chake, masiku ano, kulimba kwa waya wa enameled kwasintha kwambiri. Zazosinthira mphamvu zazing'onokuzungulira 50W, nthawi zambiri timapita ndi mafupa apulasitiki osayaka moto ndikuyika makhomawo. Ingoonetsetsani kuti mukugwiritsa ntchito waya wamphamvu kwambiri, ndipo mukamamaliza, sungani chilichonse chosanjikiza ndi chosanjikiza - palibe ma diagonal akulu omwe amaloledwa! Izi zimathandiza kupewa kukulitsa kusiyana kwa magetsi pakati pa mawaya. Kwa ma thiransifoma opitilira 50W, popeza pali matembenuzidwe ochepa pa volt, kusiyana kwa mawaya pakati pa mawaya kumakwera. Ndi bwino kuyika pepala lotsekera (monga pepala lochindikala la 0.05mm kapena pepala la kraft) pagawo lililonse pamene mukulipiringiza.
Mukufuna kuletsa zigawo zilizonse zapamwamba kuti zisagwere m'munsi! Kutsekera pakati pa windings kuyenera kudalira kuchuluka kwa magetsi omwe mukuchita nawo. Pakati pa magawo oyambirira, yesetsani kukhala ndi zigawo zinayi za pepala la chingwe cha 0.1mm-lumphani kugwiritsa ntchito tepi yodzimatira pano! Ngati thiransifoma yanu yaying'ono ili ndi magulu opitilira awiri a ma windings achiwiri olumikizidwa palimodzi, onetsetsani kuti mwawonjezeranso zigawo ziwiri zazitsulo zamapepala pakati pa gulu lililonse. Ndipo ngati thiransifoma iyi ikupita ku zida zomvera kapena zomvera? Musaiwale kuphatikizira zotchingira zotchingira ma electrostatic muzokhazikitsira zosanjikiza zambiri. Mukachita zinthu zonse zokhotakhota, tcherani khutu mukayika mapepala achitsulo a silicon - amayenera kukwanira bwino kuti musamve phokoso lamagetsi losokoneza zinthu.
Kaya ndi mapepala opangidwa ndi E-owirikiza kapena amtundu wa EI, ayenera kulumikizidwa molimba popanda mipata; kuwawoloka nawonso kungathandize! Mukayika zidutswa zingapo zomaliza (pafupifupi zinayi kapena zisanu), chitani kuchokera pakati kuti musawononge mitolo yama waya panjira. Ndiye tiyeni tiwumitse ndikuwuviika mu utoto pambuyo pake! Kwa thiransifoma pansi pa 50W, mutha kugwiritsa ntchito njira yoyanika ya endothermic: chepetsani ma windings onse achiwiri poyamba ndikulumikiza babu (60 ~ 100W / 220V) motsatizana ndi mphamvu ya mains kuti itenthe yokha. kutentha kwapamwamba, koma kutsekedwa, kotero kuti kutentha kuli pansi pa madigiri 80 ndikotetezeka.
