Umgomo wokusebenza wento ye-inductor | ULULAME

Isebenza kanjani i- inductor ? Ngizokunikeza impendulo enemininingwane namuhla.

I-inductor iyisici esiguqula amandla kagesi abe amandla kazibuthe, futhi inani le- inductance libonisa ikhono lamanje lokukhiqiza inkambu kazibuthe. Ngaphansi komshini ofanayo wamanje, ukusonta ucingo lube ikhoyili enamajika amaningi kungakhuphula insimu kazibuthe, futhi ukwengeza izinto ezisebenza kazibuthe ezifana ne-iron core ngaphakathi kwekhoyili kungakhuphula kakhulu amandla kazibuthe. Ngakho-ke, inductance evamile ikhoyili enensimbi eyakhelwe ngaphakathi.

Inductance

Lapho ikhoyili idlula ku-current, induction ye-magnetic field induction yakheka kukhoyili, futhi insimu yamagnetic eyenziwe ikhiqiza yamanje eyenzelwe ukumelana nokudlula kwamanje kukhoyili. Lokhu kusebenzisana sikubiza ngokuthi i-current kanye nekhoyili i-inductance, noma i-inductance, kokuthi "Henry" (H). Lesi sici singasetshenziswa futhi ukwenza ama- elementi e-inductor.

I-inductance isilinganiso sokuguquguquka kazibuthe kocingo kuya kweyamanje ekhiqiza ukugeleza okushintshanayo ngaphakathi kwentambo lapho ijika elishintshanayo lidlula ocingweni. Lapho i-inductor idlula i-DC yamanje, kukhona umugqa wamandla kazibuthe omisiwe owuzungezile, ongashintshi ngokuhamba kwesikhathi.

Kodwa-ke, lapho i-AC current idlula kukhoyili, kuzoba khona umugqa wamandla kazibuthe oyizungezile oshintshayo ngokuhamba kwesikhathi. Ngokomthetho kaFaraday we-electromagnetic induction-magnetoelectricity, umugqa wamandla kazibuthe oguqukayo uzokhiqiza amandla atholwe kuzo zombili iziphetho zekhoyili, elilingana "nokunikezwa kwamandla okusha".

Uma kwakhiwa iluphu evaliwe, leli khono elenziwe likhiqiza i-current induced. Kuyaziwa ngokomthetho kaLenz ukuthi inani eliphelele lemigqa yamandla kazibuthe ekhiqizwa amandla amanje kufanele azame ukuvimbela ukuguqulwa kwemigqa yamandla kazibuthe. Ushintsho lolayini wamandla kazibuthe luvela ekushintsheni kokuphakelwa kwamandla ashintshana kwangaphandle, ngakho-ke kusukela kumphumela wenjongo, ikhoyili ye-inductor inesici sokuvimbela ushintsho lwamanje kumjikelezo we-AC.

Ikhoyili ye-inductance inezici ezifana ne-inertia kumakhenikha, ngogesi ebizwa ngokuthi "self-induction". Izinhlansi zivame ukwenzeka ngesikhathi sokudonsa isishicileli sommese noma sokuvula iswishi yommese, okubangelwa amandla aphezulu adangelwe okubangelwa isenzakalo sokuzithokozisa.

Ngamafuphi, uma ikhoyili ye-inductor ixhunywe kugesi we-AC, ulayini wamandla kazibuthe ongaphakathi kwekhoyili uzoshintsha namandla ashintshayo, okuholela ekungeneni kozibuthe wekhoyili. Lolu hlobo lwamandla e-electromotive olubangelwa ukushintsha kwamandla ekhoyili ngokwayo lubizwa ngokuthi "i-self-inductive electromotive force". Ngakho-ke kungabonakala ukuthi i-inductance kuphela ipharamitha ehlobene nenombolo, usayizi, ukuma kanye nendawo yekhoyili, futhi iyisilinganiso se-inertia yekhoyili ye-inductor futhi ayihlangene namanje osetshenzisiwe.

Umgomo wokushintsha:

1. Ikhoyili ye-inductor kufanele ithathelwe indawo ivelu yokuqala (inani lokujika liyalingana futhi nosayizi uyafana).

2. I-patch inductor idinga kuphela usayizi ofanayo, futhi ingashintshwa ngo-0 ohm ukumelana noma ucingo.

Okungenhla ukwethulwa kwesimiso sokusebenza sama-inductors. Uma ufuna ukwazi okwengeziwe ngama-inductors, sicela ukhululeke ukuxhumana nathi.
