Kodi mungamvetse bwanji kuti otembenuza abwino samasunga mphamvu, koma ma inductors amatha kusunga mphamvu yamagetsi?

Choyamba, ngati mphamvu ikhoza kusungidwa, tiyeni tiwone kusiyana pakati pa zosintha zabwino ndi zosinthira zenizeni:

1. Tanthauzo ndi makhalidwe a osintha abwino

Njira zojambulira zofananira za ma transformer abwino

Transformer yabwino ndi chinthu chozungulira. Imalingalira: palibe kutayikira kwa maginito, palibe kutayika kwa mkuwa ndi kutayika kwachitsulo, komanso kudziletsa kopanda malire ndi ma coefficients ogwirizana ndipo sizisintha ndi nthawi. Pansi pa malingaliro awa, thiransifoma yabwino imangozindikira kutembenuka kwa voteji ndi zamakono, popanda kuphatikizira kusungirako mphamvu kapena kuwononga mphamvu, koma kumangotengera mphamvu zamagetsi mpaka kumapeto.

Chifukwa palibe kutayikira kwa maginito, mphamvu ya maginito ya thiransifoma yabwino imangokhala pachimake, ndipo palibe mphamvu yamaginito yomwe imapangidwa m'malo ozungulira. Panthawi imodzimodziyo, kusowa kwa mkuwa ndi kutayika kwachitsulo kumatanthauza kuti thiransifoma sichidzasintha mphamvu zamagetsi kuti zikhale kutentha kapena mitundu ina ya kutaya mphamvu panthawi yogwira ntchito, komanso sichidzasunga mphamvu.

Malinga ndi zomwe zili mu "Mfundo Zam'dera": Pamene thiransifoma yokhala ndi chitsulo chachitsulo imagwira ntchito mu unsaturated core, mphamvu yake ya maginito imakhala yaikulu, kotero kuti inductance ndi yaikulu, ndipo kutayika kwapakati sikungatheke, kungathe kuonedwa ngati koyenera. thiransifoma.

Tiyeni tionenso mawu ake omaliza. "Mu thiransifoma yabwino, mphamvu yotengedwa ndi mafunde oyambira ndi u1i1, ndipo mphamvu yomwe imalowetsedwa ndi mafunde achiwiri ndi u2i2=-u1i1, ndiye kuti, mphamvu yolowera mbali yoyambira ya thiransifoma imachokera ku katundu kudzera mu mbali yachiwiri. Mphamvu yonse yomwe imatengedwa ndi thiransifoma ndi zero, kotero chosinthira choyenera ndi chigawo chomwe sichisunga mphamvu kapena kugwiritsa ntchito mphamvu.

” Inde, abwenzi ena adanenanso kuti mu flyback circuit, transformer imatha kusunga mphamvu. M'malo mwake, ndidayang'ana chidziwitsocho ndikuwona kuti chosinthira chake chotulutsa chimakhala ndi ntchito yosunga mphamvu kuwonjezera pakukwaniritsa kudzipatula kwamagetsi ndi kufananitsa voteji.Zakale ndi katundu wa transformer, ndipo chomaliza ndi katundu wa inductor.Choncho, anthu ena amachitcha kuti inductor transformer, zomwe zikutanthauza kuti malo osungirako mphamvu ndi katundu wa inductor.

2. Makhalidwe a ma transformer mu ntchito yeniyeni

Pali kuchuluka kwa mphamvu yosungiramo mphamvu mu ntchito yeniyeni. Mu ma transformer enieni, chifukwa cha zinthu monga kutayikira kwa maginito, kutaya mkuwa ndi kutayika kwachitsulo, thiransifomayo idzakhala ndi mphamvu yosungiramo mphamvu.

Pakatikati pachitsulo cha thiransifoma chidzatulutsa kutaya kwa hysteresis ndi kutayika kwa eddy panopa pansi pa mphamvu ya maginito. Zotayika izi zidzawononga gawo la mphamvuyo ngati mphamvu ya kutentha, komanso zidzachititsa kuti mphamvu ya maginito isungidwe muzitsulo zachitsulo. Choncho, pamene thiransifoma ikugwiritsidwa ntchito kapena kudulidwa, chifukwa cha kumasulidwa kapena kusungirako mphamvu ya maginito muzitsulo zachitsulo, kuwonjezereka kwa nthawi yochepa kapena kuphulika kumachitika, zomwe zimapangitsa kuti pakhale mphamvu pa zipangizo zina mu dongosolo.

3. Inductor mphamvu yosungirako makhalidwe

Pamene panopa mu dera akuyamba kuwonjezeka, ndiinductorzidzalepheretsa kusintha kwamakono. Malinga ndi lamulo la electromagnetic induction, mphamvu yamagetsi yodzipangira yokha imapangidwa kumapeto onse a inductor, ndipo mayendedwe ake amatsutsana ndi momwe kusintha kwasinthira. Panthawiyi, mphamvu yamagetsi iyenera kugonjetsa mphamvu yodzipangira yokha ya electromotive kuti igwire ntchito ndikusintha mphamvu yamagetsi kukhala mphamvu ya maginito mu inductor kuti isungidwe.

Zomwe zilipo panopa zikafika pamtunda wokhazikika, mphamvu ya maginito mu inductor sisinthanso, ndipo mphamvu yodzipangira yokha ya electromotive ndi zero. Panthawiyi, ngakhale kuti inductor sichitenganso mphamvu kuchokera kumagetsi, imasungabe mphamvu ya maginito yomwe imasungidwa kale.

Pamene panopa mu dera likuyamba kuchepa, mphamvu ya maginito mu inductor idzafowoka. Malingana ndi lamulo la electromagnetic induction, inductor idzapanga mphamvu yodzipangira yokha yamagetsi mofanana ndi kuchepa kwamakono, kuyesera kusunga kukula kwa panopa. Pochita izi, mphamvu ya maginito yomwe imasungidwa mu inductor imayamba kumasulidwa ndikusinthidwa kukhala mphamvu yamagetsi kuti idyetsenso dera.

Kupyolera mu njira yake yosungiramo mphamvu, tikhoza kumvetsetsa kuti poyerekeza ndi thiransifoma, imakhala ndi mphamvu zowonjezera komanso zopanda mphamvu, choncho mphamvu zimasungidwa.

Zomwe zili pamwambazi ndi maganizo anga. Ndikukhulupirira kuti zithandiza onse opanga ma bokosi athunthu kuti amvetsetse zosintha ndi ma inductors! Ndikufunanso kugawana nanu chidziwitso cha sayansi:thiransifoma yaying'ono, ma inductors, ndi ma capacitor omwe atulutsidwa kuchokera ku zida zapakhomo ayenera kutulutsidwa musanakhudzidwe kapena kukonzedwa ndi akatswiri pambuyo pozimitsa magetsi!
