Yoqobo: Ukukhanya kwezixhobo
Kwizibalo zethiyori, sicinga ukuba ixabiso le-AL le-magnetic core efanayo lizinzile kwaye asicingi ngempembelelo yezinye izinto kwixabiso le-AL. Nangona kunjalo, ekusebenzeni okusebenzayo, ixabiso le-AL liphenjelelwa zizinto ezahlukeneyo. Eli nqaku liza kulichaza ngemizekelo evela kumalungu eqela.
Ndine-magnetic core ene-8Ts coils, kwaye ixabiso le-inductance elivavanyiweyo limalunga ne-5.3uH; Kodwa xa ndandivavanya nge-80Ts coil, ixabiso le-inductance laliyi-610uH. Yintoni isizathu soku?
Ngokwethiyori, ii-80Ts mazibe malunga ne-530uH. Uvavanyo lwe-single coil lusebenzisa isibini esifanayo see-magnetic cores kunye nolu hlobo lwe-flat coil.
Thatha umfanekiso wemveliso yonke, kuquka imilo ye-magnetic core kunye ne-coil, kwaye ingaba kukho na umsantsa womoya? Ifektri ye-magnetic core ikwachaza ixabiso le-AL njengee-turns ezili-10, kwaye impazamo eqhelekileyo ayinkulu kangako.
Xa inani leenguqu lincinci, umlinganiselo we-inductance yokuvuza ukuya kwi-inductance uya kuba mkhulu, ngoko ke impazamo ye-inductance iya kuba nkulu xa inani leenguqu lincinci; Ukongeza, ii-flat coils ziya kwandisa esi siphumo, kwaye ukuba yi-coil eqhelekileyo, isiphumo sinokuba ncinci.
Enye ingxaki kukujika kovavanyo. Xa inani lokujika lincinci, uvakalelo luphantsi, kwaye isiphumo se-hysteresis sinempembelelo enkulu ekujikeni kovavanyo lovakalelo; Kakade ke, kukwakho nokwenzeka ukuba i-magnetic core igcwale xa inani lokujika lincinci, ngoko ke ixabiso lovakalelo lovavanyo alikho ngqiqweni.
Kukho umsantsa womoya, kwaye umfanekiso wemveliso ngolu hlobo lulandelayo:
Amaxabiso e-AL onke ngamaxabiso ovavanyo angenamsantsa womoya, ngoko ke kuqhelekile ukuba ube nomsantsa womoya.
Kufuneka siqwalasele impembelelo yomsantsa womoya apha. Luhlobo luni kunye nezinto ezisetyenziswa yi-magnetic core? Unzulu kangakanani umsantsa womoya?
Kule meko, ndaqala ukuqwalasela ukuba kungenxa yesithuba somoya. Ngokusekelwe kwiifomyula kunye namanqaku aphambili kwinqaku elithi “Ukubala kunye neNkcazelo yoMzekelo weSithuba soMoya kwiiTransformers”, kwenziwa izibalo ezifanelekileyo.
Uthelekiso lubonisa ukuba impembelelo yezikhewu zomoya ayibalulekanga kangako. (Ayiphindaphindwa apha. Amaqela anomdla angabala aze athelekise umahluko kubuntununtunu ngokudibanisa iifomyula kunye neeparameter ezisisiseko zee-magnetic cores.)
Ingakumbi kwi-magnetic core efanayo, umsantsa womoya awuguquki. I-80TS ikwimeko enenani elikhulu lokujika. Xa idibene nesakhiwo, ndicinge nangefomula L=(0.01 * D * N * N)/(L/D+0.44) yeekhoyili ezingenanto. Njengoko inani lokujika lisanda, i-inductance yejika ngalinye iyanda.
Kwimeko yezangqa ezininzi, le nto iya kudlala indima ephambili, nto leyo eyenza ingcaciso ibe nengqiqo.
Kukwakho nedatha ebonisa ukuba njengoko inani leenguqu lisanda, i-inductance coefficient iyanda kuba ukujika ngakunye kwikhoyili kufana nokuvelisa i-magnetic flux, eyandayo ngenani leenguqu.
Ngokusekelwe kwizifundo zetyala, ndiqinisekisile ezinye iimeko ezininzi, kwaye kweli tyala, i-inductance inkulu kakhulu. Ngelishwa, okwangoku akukho fomula ichanekileyo yokushwankathela le meko.
Kubonakala ngathi kwimveliso enkulu, ii-transformers kufuneka zisebenzise ikhoyili efanayo ukucola umsantsa womoya, kwaye kukho nezinto ekufuneka ziqwalaselwe kule nkalo.
