Iikhoyili zokutshaja ezingenazingcingozisetyenziswa ngokubanzi, kwaye iimilo kunye neendlela ezijikajikayo zeekhoyili ze-inductance ziyahluka. Izixhobo zokujija ezahlukeneyo ziya kusetyenziswa ukuvuthela iikhoyili ezahlukeneyo, ngenxa yeemfuno zokubunjwa kwezixhobo zokutshaja ezahlukeneyo.
Zininzi izimbo kunye neendidi zeemveliso zekhoyili eziveliswayo, kunye nezixhobo zokutshaja ezingenazingcingo ezisebenzayo nazo zibanzi kakhulu. Iikhoyili ezahlukeneyo zokutshaja ezingenazingcingo ziyilwe ngokweemfuno zomsebenzisi.
Namhlanje siza kwazisa indlela yokuqinisekisa iModeli yeKhoyili yokuTshaja okungenazingcingo?
1. Ngokweemfuno zesekethe , Khetha indlela yokujija
Xa ujija ikhoyili yokutshaja ngaphandle kwamacingo, kuyimfuneko ukuqwalasela iimfuno zesekethe yesixhobo sokutshaja ngaphandle kwamacingo, i-inductance, kunye nobukhulu bocingo. Qinisekisa indlela yokujija phambi kokwenza ukubumba.
Iikhoyili zokutshaja ezingenazingcingobangamanxeba ukusuka ngaphakathi ukuya ngaphandle, ngoko ke inyathelo lokuqala kukuqinisekisa idiameter yangaphakathi. Qinisekisa iileyile, ubude, ububanzi obungaphandle, njl njl. yekhoyili esekelwe kwizinto zombane ezifana ne-inductance kunye nokumelana.
Iikhoyili zokutshaja ezingenazintambo zifanelekile kumaza amafutshane kunye neesekethe zamaza aphakathi, kunye namaxabiso e-Q ukusuka kwi-150 ukuya kwi-250, ukuzinza okuphezulu.
Emva kweucingo lokutshaja ikhoyiliifakwe umbane, yenza imagnethi eyijikelezileyo, yenze imilo engqukuva. Okukhona kukho iikhoyili ezininzi, kokukhona umlinganiselo wemagnethi umkhulu. Okukhona umbane udlula ngexesha leyunithi nganye, kokukhona ukuqina kwemagnethi. Ngokusekwe kwisiphumo solusu lwangoku, iingcingo ezishinyeneyo zinokufumana indawo eyomeleleyo yamagnetic kuneengcingo ezincinci.
Ukuphucula ukusetyenziswa kwendawo, ucingo olusetyenziselwa ikhoyili luvamise ukuba lufakwe i-enameled ucingo. Xa ukhetha izixhobo ze-automation for winding, ukulungiswa kwecingo kubaluleke kakhulu, Ngocingo olulodwa, oko kufuneka kuqwalaselwe ukujika kunye neengqimba.
Indlela yokubeka ikhoyili inqunywe ngokusekelwe ekubeni ifuna ukugcina indawo okanye ukuphucula ukuchithwa kobushushu, kwaye ngokuqhelekileyo kukho ubudlelwane obungenakulinganiswa phakathi kweemfuno ezininzi.
Xa uvala iucingo lokutshaja ikhoyili, sifanele sinikele ingqalelo kwezi zinto zikhankanywe ngasentla.
2. Ngokwe-frequency yokusebenza, khetha i-core efanelekileyo.
Iikhoyili ezinamaza ahlukeneyo zineempawu ezahlukeneyo, kunye ne-magnetic cores yezixhobo ezahlukeneyo kufuneka zikhethwe ngokusekelwe kwiimpawu.
Ukutshaja okungenacingo ukufumana ikhoyiliisetyenziswa kwi-audio low frequency operation, ngokubanzi kusetyenziswa i-silicon steel sheet okanye i-permalloy njengento engundoqo yemagnethi. I-ferrite yefrikhwensi ephantsi isetyenziswa njengesixhobo esingundoqo samagnetic, esine-inductance enkulu, kunye ne-inductance yekhoyili yokutshaja engenazingcingo inokuba phezulu ukuya kumashumi ambalwa kaHenry.
Kwiikhoyili kwicandelo losasazo lwamaza aphakathi, ii-cores ze-ferrite zikhethwa ngokubanzi kwaye zilimaze ngeengcingo ezininzi ezigqunyiweyo. Kwi-frequency ephezulu, ikhoyili iya kusebenzisa i-ferrite ephezulu-frequency njengondoqo wamagnetic, kwaye iikhoyili ezingenanto zisetyenziswa ngokuqhelekileyo. Kule meko, akucetyiswa ukuba kusetyenziswe iingcingo ezininzi ezigqunyiweyo, kodwa endaweni yoko kusetyenziswe umcu omnye ongqindilili wesilivere ocwecwe ngocingo lokujija.
Ukuba amaza angaphezulu kwe-100MHz, ii-ferrite cores azisekho, kwayeukutshaja ngaphandle kwamacingo kunye nokufumana iikhoyiliunokusebenzisa kuphela iikhoyili ezingenanto; Ukuba ufuna ukwenza uhlengahlengiso oluncinci, ungasebenzisa intsimbi yentsimbi.
Ukongeza kokuhlangabezana neemfuno zesekethe ye-inductance kunye nokulinganiswa kwangoku, kubalulekile ukuba uqaphele ukuba i-capacitance esasazwayo ye-coil yokutshaja engenazintambo esetyenziswe kwiisekethe eziphezulu ze-frequency akufanele ibe nkulu kakhulu.
