Ikhoyili ye-electromagnetic yeloli i-ABS elawula ivalvu 4721950520

Ikhoyili evamile

1. Ikhoyili yongqimba olulodwa

Ikhoyili yongqimba olulodwa iboshwe eduze kweshubhu lephepha noma uhlaka lwamathambo e-bakelite ngezintambo ezivalekile ngayinye ngayinye.Okufana nekhoyili ye-antenna emsakazweni we-transistor.

2. Ikhoyili yekhekheba lezinyosi

Uma indiza yekhoyili yesilonda ingahambelani nendawo ezungezayo, kodwa inqamula i-engeli ethile, lolu hlobo lwekhoyili lubizwa ngokuthi ikhoyili yekhekheba lezinyosi.Futhi inani lezikhathi ucingo olugoba ngalo emuva naphambili lapho luzungeza kanye, okuvame ukubizwa ngokuthi inani lezindawo ezigoqayo.Indlela ye-honeycomb winding inezinzuzo zevolumu encane, i-capacitance encane esabalalisiwe kanye ne-inductance enkulu.Amakhoyili ekhekheba lezinyosi wonke alinyazwa umshini wokusonteka wekhekheba lezinyosi.Amaphoyinti okugoqa amaningi, aba mancane amandla asabalalisiwe.

3. Ikhoyili ye-ferrite core kanye ne-iron powder core

I-inductance yekhoyili ihlobene nokuthi kukhona yini ingqikithi kazibuthe noma cha.Ukufaka i-ferrite core ku-air-core coil kungakhuphula i-inductance futhi kuthuthukise ikhwalithi yekhoyili.

4, ikhoyili yethusi core

Ikhoyili ye-Copper core isetshenziswa kabanzi ku-ultrashort wave range.Kuyinto elula futhi ihlala isikhathi eside ukushintsha inductance ngokuzungezisa indawo yethusi core kukhoyili.

5, umbala ikhodi inductor

I-inductor enekhodi enombala iyi-inductor ene-inductance engaguquki, futhi inductance yayo imakwa ringtone yombala efana ne-resistor.

6, ukuminyanisa ikhoyili (minyanisa)

Ikhoyili evimbela ukudlula kwe-alternating current ibizwa ngokuthi i-choke coil, yona ingahlukaniswa ibe ikhoyili yokuklinya enefrikhwensi ephezulu kanye nekhoyili yokuminyanisa enefrikhwensi encane.

7. Ikhoyili ephambukayo

Ikhoyili ephambukayo umthwalo wesigaba sokuphumayo sesekethe ye-TV scanning.Ikhoyili ephambukayo idinga ukuzwela okukhulu kokuchezuka, indawo efanayo kazibuthe, inani eliphakeme le-Q, usayizi omncane kanye nenani eliphansi.

umsebenzi

Khipha isenzo

I-self-indused electromotive force kukhoyili ye-inductance njalo iphikisana noshintsho lwamanje lwekhoyili.Ikhoyili ye-inductance inomphumela wokuvimba ku-AC yamanje, futhi usayizi womphumela wokuvimba ubizwa ngokuthi i-inductance xl, futhi iyunithi ithi ohm.Ubudlelwano bayo ne-inductance L kanye ne-AC frequency F yi-xl=2πfl.Ama-inductors angahlukaniswa kakhulu abe amakhoyili okuklinywa anemvamisa ephezulu kanye namakhoyili okuminyanisa anemvamisa ephansi.

Ukushuna nokukhetha imvamisa

I-lc tuning circuit ingakhiwa ngokuxhuma ikhoyili ye-inductance kanye ne-capacitor ngokuhambisana.Okusho ukuthi, imvamisa yemvelo ye-oscillation f0 yesekethe ilingana nemvamisa f yesiginali engashintshisani, ngakho-ke ukusabela kwe-inductive kanye nokusabela kwe-capacitive kwesekethe nakho kuyalingana, ngakho-ke amandla kazibuthe kagesi azulazula aye emuva naphambili ku-inductance futhi i-capacitance, okuyi-resonance phenomenon yesekethe ye-lc.Ku-resonance, ukusabela kwe-inductive kanye ne-capacitive reactance yesekethe kuyalingana futhi kuphambene, futhi ukusabela kwe-inductive kwesamba se-loop yamanje kuncane kakhulu futhi okwamanje kukhulu (kubhekiselwa kusignali ye-AC eno-f = "F0").I-lc resonant circuit inomsebenzi wokukhetha imvamisa, engakhetha isignali ye-AC ngokuthile
