Okwangempela: Ukukhanya Kwamadivayisi
Ekubalweni kwethiyori, sicabanga ukuthi inani le-AL le-magnetic core efanayo lizinzile futhi asicabangi ngethonya lezinye izici enanini le-AL. Kodwa-ke, ekusebenzeni okungokoqobo, inani le-AL lithonywa izici ezahlukahlukene. Lesi sihloko sizosichaza ngezibonelo ezivela kumalungu eqembu.
Nginomgogodla odonsayo onamakhoyili angu-8Ts, futhi inani lokungenisa elivivinyiwe licishe libe ngu-5.3uH; Kodwa lapho ngihlola ngekhoyili engu-80Ts, inani lokungenisa lalingu-610uH. Iyini imbangela yalokhu?
Ngokwethiyori, ama-80T kufanele abe cishe ku-530uH. Ukuhlolwa kwekhoyili eyodwa kusebenzisa ama-cores afanayo kamagnetic kanye nalolu hlobo lwekhoyili eyisicaba.
Thatha isithombe somkhiqizo wonke, kufaka phakathi ukuma kwe-magnetic core kanye ne-coil, nokuthi ngabe kukhona yini isikhala somoya? Ifektri ye-magnetic core iphinde ichaze inani le-AL njengama-turns ayi-10, futhi iphutha elijwayelekile alilikhulu kangako.
Uma inani lokujika lincane, isilinganiso sokuvuza kokuvuza kuya kokujika sizoba sikhulu, ngakho-ke iphutha lokujika lizoba likhulu uma inani lokujika lincane; Ngaphezu kwalokho, ama-flat coil azokwandisa lo mphumela, futhi uma kuyi-coil evamile, umphumela ungaba mncane.
Enye inkinga ukuphambuka kokuhlola. Uma inani lokujika lincane, ukuzwela kuphansi, futhi umphumela we-hysteresis unomthelela omkhulu ekuphambukisweni kokuzwela kokuhlola; Vele, kukhona futhi ithuba lokuthi umongo wamagnetic ugcwale lapho inani lokujika lincane, ngakho-ke inani lokuzwela kokuhlola alilona iqiniso.
Kukhona isikhala somoya, futhi isithombe somkhiqizo simi kanje:
Amanani e-AL wonke angamanani okuhlola angenasikhala somoya, ngakho-ke kuyinto evamile ukuthi ube nesikhala somoya.
Kudingeka sicabangele ithonya legebe lomoya lapha. Hlobo luni kanye nezinto ezisetshenziswayo ze-magnetic core? Igebe lomoya lijule kangakanani?
Kulokhu, ngaqala ukucabanga ukuthi kwakungenxa yesikhala somoya. Ngokusekelwe kumafomula namaphuzu abalulekile esihlokweni esithi “Ukubalwa kanye Nencazelo Yesibonelo Yesikhala Somoya Kuma-Transformers”, kwenziwa izibalo ezifanele.
Ukuqhathanisa kwembula ukuthi umthelela wezikhala zomoya awubalulekile kangako. (Akuphindwa lapha. Amaqembu anentshisekelo angabala futhi aqhathanise umehluko ekuzweleni ngokuhlanganisa amafomula kanye nemingcele eyisisekelo yama-cores magnetic.)
Ikakhulukazi ku-core efanayo yamagnetic, igebe lomoya lizinzile. I-80TS ingeyesimo esinokushintshana okukhulu. Uma kuhambisana nesakhiwo, ngicabange nangefomula L=(0.01 * D * N * N)/(L/D+0.44) yama-hollow coils. Njengoba inani lokujika likhula, ukuguquguquka kokujika ngakunye kuyanda.
Uma kunezindilinga eziningi, lesi sici sizodlala indima evelele, okwenza incazelo ibe nengqondo.
Kukhona futhi idatha ekhombisa ukuthi njengoba inani lokujika likhuphuka, i-inductance coefficient iyanda ngoba ukujika ngakunye kukhoyili kufana nokukhiqiza i-magnetic flux, eyanda ngenani lokujika.
Ngokusekelwe ezifundweni zamacala, ngiqinisekisile amacala amaningana, futhi kulokhu, i-inductance inkulu kakhulu. Ngeshwa, okwamanje ayikho ifomula enembile yokufingqa lesi simo.
Kubonakala sengathi ekukhiqizweni okukhulu, ama-transformer adinga ukusebenzisa ikhoyili efanayo ukugaya igebe lomoya, futhi kukhona nezinto okufanele zicatshangelwe kulokhu.
