Isishwankathelo seePropati zeInductance| PHILA

Kwisekethe, intsimi ye-electromagnetic yenziwa xa ikhoyo ngoku ihamba nge-conductor. ubukhulu bendawo ye-electromagnetic field eyahlulwe ngoku yi- inductance .

I-Inductance sisixa somzimba esilinganisa ukukwazi kwekhoyili ukuvelisa induction ye-electromagnetic. Ukuba umbane wombane usetyenziswe kwikhoyili, intsimi yamagnetic iya kuveliswa malunga nekhoyili, kwaye i-coil iya kuba ne-flux magnetic edlula kuyo. Okukhona unikezelo lwamandla ngakumbi kwikhoyili, kokukhona womelele umhlaba wemagnethi kwaye kokukhona umbane wemagnethi udlula kwikhoyili. Iimvavanyo zibonisa ukuba i-magnetic flux ngokusebenzisa ikhoyili ilingana nekhoyo ngoku engenayo, kwaye umlinganiselo wabo ubizwa ngokuba yi-self-inductance, eyaziwa ngokuba yi-inductance.

Ukuhlelwa kwe-inductance

Ihlelwe ngokohlobo lwe-inductor: i-inductor esisigxina, i-inductor eguquguqukayo.

Ihlelwe ngokweempawu zokuqhuba imagnethi: ikhoyili engenanto, ikhoyili yeferrite, icoil engundoqo yentsimbi, ikhoyili engundoqo yobhedu.

Ihlelwa ngokwendalo yokusebenza: ikhoyili ye-antenna, ikhoyili ye-oscillation, icoil yokuminxa, inotshi ikhoyili, ikhoyili ephambukayo.

Ihlelwe yintsimbi ejikelezayo: i-coil-single-coil coil, multi-layer coil, honeycomb coil.

Ihlelwa ngokusebenza rhoqo: ikhoyili ephezulu, icoil ephantsi.

Ihlelwe ngokweempawu zesakhiwo: i-coil yamagnetic core, i-coil inductance eguquguqukayo, ikhowudi yombala we-coil inductor coil, i-coil non-core kunye nokunye.

Ii-inductors eziHollow, ii-inductors ezingundoqo ezizibuthe kunye nee-copper core inductors zihlala ziphakathi okanye zi-inductors eziphakamileyo, ngelixa ii-iron core inductors zidla ngokuba zii-frequency inductors ezisezantsi.

Izinto eziphathekayo kunye neteknoloji ye-inductor

Ii-inductors ngokubanzi zenziwe ngamathambo, ukujikajika, ikhaka, imathiriyeli yokupakisha, undoqo wemagnethi njalo njalo.

1) I-Skeleton: ngokubanzi ibhekisa kwinkxaso yee-coil ezijikelezayo. Ngokuqhelekileyo yenziwe ngeplastiki, i-Bakelite kunye neekeramics, ezinokuthi zenziwe kwiimilo ezahlukeneyo ngokweemfuno zangempela. Ii-inductors ezincinci azisebenzisi i-skeleton, kodwa zivuthe i-enamelled wire ngqo kumbindi. I-inductor egobileyo ayisebenzisi i-core magnetic, skeleton kunye nekhuselo lokugubungela, kodwa inxeba lokuqala kwi-mold kwaye emva koko lisuse ukungunda, kwaye tsala umgama othile phakathi kweekhoyili.

2) Umoya: iqela leekhoyili ezinemisebenzi echaziweyo, enokuthi ihlulwe ibe yinqanaba elilodwa kunye ne-multi-layer. Umaleko omnye uneendlela ezimbini zokujija ngokusondeleyo kunye nokujika ngokuthe ngqo, kwaye uluhlu oluninzi luneentlobo ezininzi zeendlela, ezifana ne-layer flat winding, i-random winding, i-honeycomb winding njalo njalo.

3) I-Magnetic core: ngokubanzi sebenzisa i-nickel-zinc ferrite okanye i-manganese-zinc ferrite kunye nezinye izinto, inemilo ethi "I", imilo yekholomu, imilo ye-cap, "E" imilo, imilo yetanki njalo njalo.

I-Iron core: ubukhulu becala ishidi le-silicon, i-permalloy njalo njalo, imilo yayo ubukhulu becala luhlobo "E".

Isigqubuthelo esikhuselayo: sisetyenziselwa ukuthintela umhlaba wemagnethi oveliswe ngamanye ama-inductors ukuba angachaphazeli ukusebenza okuqhelekileyo kwezinye iisekethe kunye namalungu. I-inductor enekhava yokukhusela iya kwandisa ilahleko yekhoyili kunye nokunciphisa ixabiso le-Q.

Izinto zokupakisha: emva kokuba ezinye ii-inductors (ezifana ne-inductor yekhowudi yombala, i-inductor yombala we-ring, njl. njl.) zizilonda, i-coil kunye ne-core zitywinwe ngezinto zokupakisha. Izinto zokupakisha zenziwe ngeplastiki okanye i-epoxy resin.

Oku ngasentla kukujongwa kweepropati ze-inductors, ukuba ufuna ukwazi ngakumbi malunga ne-inductors, nceda uzive ukhululekile ukuqhagamshelana nathi.
