Ukutholwa kwekhoyili ye-inductance

(1) Lapho ukhetha futhi usebenzisa ikhoyili ye-inductance,kufanele siqale sicabange ngokuhlola kanye nokukalwa kwekhoyili, bese sahlulela izinga lekhoyili. Ukuze uthole ngokunembile i-inductance kanye nekhwalithi ye-factor Q yekhoyili ye-inductance, amathuluzi akhethekile ngokuvamile ayadingeka, futhi indlela yokuhlola iyinkimbinkimbi kakhulu. Emsebenzini ongokoqobo, lolu hlobo lokutholwa ngokuvamile alwenziwa, kodwa kuphela ukuhlolwa kokucisha kwekhoyili kanye nokwahlulela kwenani le-Q. Okokuqala, ukumelana kwe-DC kwekhoyili kungalinganiswa kusetshenziswa ifayela lokumelana ne-multimeter, bese kuqhathaniswa nenani langempela elinqunyiwe lokumelana noma inani lokumelana okulinganiselwe. Uma inani lokumelana elilinganisiwe liphakeme kakhulu kunevelu yokumelana enqunyiwe yasekuqaleni noma inani lokumelana okulinganiselwe, ngisho noma isikhombisi singanyakazi (inani lokumelana livame uku-infinity X), kunganqunywa ukuthi ikhoyili iphukile. Uma ukumelana okukaliwe kukuncane kakhulu, kunzima ukuqhathanisa ukuthi isifunda esifushane esibucayi noma isifunda esifushane sendawo. Uma lezi zimo ezimbili zenzeka, kungabhekwa ukuthi ikhoyili yimbi futhi ayikwazi ukusetshenziswa. Uma ukumelana nokubonwa kungahluka kakhulu kulokho okunqunyiwe kwasekuqaleni noma ukumelana negama nje, kungabhekwa ukuthi ikhoyili yinhle. Kulokhu, singahlulela ikhwalithi yekhoyili, okungukuthi, ubukhulu benani le-Q, ngokuvumelana nezimo ezilandelayo. Uma inductance yekhoyili ifana, uma kuncane ukumelana ne-DC, inani le-Q liphezulu. Uma bukhulu ububanzi bocingo olusetshenzisiwe, likhulu inani layo elingu-Q; Uma kusetshenziswa i-multi-strand winding, lapho izintambo eziningi zocingo, ziphakama inani le-Q; Ukulahlekelwa okuncane kwento esetshenziswa kukhoyili bobbin (noma i-iron core), iba nkulu inani layo elingu-Q. Isibonelo, lapho ishidi lensimbi ye-silicon ephezulu lisetshenziswa njengensimbi, inani lalo le-Q liphakeme kunalelo lapho kusetshenziswa ishidi lensimbi ye-silicon evamile njengensimbi; Uma kuncane amandla asabalalisiwe kanye nokuvuza kazibuthe kwekhoyili, kuphakama inani layo elingu-Q. Isibonelo, inani elingu-q lekhoyili ejikajikayo yekhekheba lezinyosi liphezulu kunalelo lokujikajika eliyisicaba futhi liphakeme kunalelo lokuphenduka okungahleliwe; Lapho ikhoyili ingenasivikelo futhi zingekho izingxenye zensimbi ezizungeze indawo yokufaka, inani layo le-Q liphakeme, ngokuphambene nalokho, inani layo le-Q liphansi. Uma isihlangu noma ingxenye yensimbi isondela kukhoyili, inani le-Q liyancipha kakhulu. Isikhundla esinomgogodla kazibuthe kufanele sihlelwe kahle futhi sicabange; Ikhoyili ye-antenna kanye nekhoyili e-oscillating kufanele iqondane, egwema umthelela wokuhlanganisana.

(2) Ikhoyili kufanele ihlolwe ngokubonakalayo ngaphambi kokufakwa.

Ngaphambi kokusetshenziswa, hlola ukuthi ukwakheka kwekhoyili kuqinile yini, ukuthi amajika axega futhi awakhululekile yini, ukuthi izixhumi zomthofu zikhululekile yini, noma ingqikithi kazibuthe iyazungeza ngokuguquguqukayo, nokuthi akhona yini izinkinobho ezishelelayo. Lezi zici zifanelekile ngaphambi kokufakwa.
