Imodi yoxhumano lwe-Thermosetting ikhoyili ye-electromagnetic SB1034/AB310-B

Izinkomba zokusebenza eziyinhloko zekhoyili ye-inductance

1.ukusabela okuguquguqukayo

Ubukhulu bokumelana kwekhoyili ye-inductance ku-AC yamanje kubizwa ngokuthi i-inductance XL, ne-ohm njengeyunithi kanye no-ω njengophawu. Ubudlelwano bayo ne-inductance L kanye ne-AC frequency F yi-XL=2πfL.

2.isici sekhwalithi

Isici sekhwalithi u-Q inani elibonakalayo elimelela ikhwalithi yekhoyili, futhi i-Q iyinani le-XL ye-inductance ekumelaneni kwayo okulinganako, okungukuthi, Q = XL/R. i-inductor isebenza ngaphansi kwe-voltage ethile ye-AC. Ukuphakama kwevelu ye-Q ye-inductor, kuncane ukulahlekelwa kanye nokusebenza kahle okuphezulu. Inani elingu-q lekhoyili lihlobene nokumelana kwe-DC komqhubi, ukulahleka kwe-dielectric kwamathambo, ukulahlekelwa okubangelwa isihlangu noma insimbi core, ithonya lomphumela we-high frequency wesikhumba nezinye izici. Inani lika-q lekhoyili livamise ukuba ngamashumi kuya kumakhulu. Ikhwalithi yekhwalithi ye-inductor ihlobene nokumelana kwe-DC kwentambo yekhoyili, ukulahlekelwa kwe-dielectric kohlaka lwekhoyili kanye nokulahlekelwa okubangelwa umgogodla nesihlangu.

3.amandla asabalalisiwe

Noma iyiphi ikhoyili ye-inductance inamandla athile phakathi kokujika, phakathi kwezendlalelo, phakathi kwekhoyili nendawo eyinkomba, phakathi kwekhoyili nesihlangu sikazibuthe, njll. Lawa mandla abizwa ngokuthi amandla okusabalalisa ekhoyili ye-inductance. Uma lawa ma-capacitor asabalalisiwe ehlanganiswa ndawonye, ​​iba i-capacitor c efanayo exhunywe ngokuhambisana nekhoyili ye-inductance. Ukuba khona kwe-capacitance esabalalisiwe kunciphisa inani le-Q lekhoyili futhi kulimaze ukuzinza kwayo, ngakho-ke ikhono elisabalalisiwe lekhoyili, liba ngcono.

4.ikalwe okwamanje

Isilinganiso samanje sisho inani lamanje i-inductor engavunyelwe ukulidlula lapho lisebenza ngokujwayelekile. Uma ukusebenza kwamanje kudlula okwamanje okulinganiselwe, imingcele yokusebenza ye-inductor izoshintsha ngenxa yokushisa, futhi ngisho izoshiswa ngenxa ye-overcurrent.

5.ukwehluka okuvumelekile

Ukuchezuka okuvunyelwe kubhekisela ephutheni elivumelekile phakathi kwe-inductance yegama kanye nendlela yangempela yokufaka i-inductor.

Ama-inductors avame ukusetshenziswa kumasekhethi e-oscillation noma okuhlunga adinga ukunemba okuphezulu, futhi ukuchezuka okuvumelekile ngu-0.2 [%] ~ 0.5 [%]; Kodwa-ke, ukunemba kwamakhoyili asetshenziselwa ukuhlanganisa, ukuminyanisa kwe-high-frequency nokunye akuphakeme; Ukuchezuka okuvumelekile ngu-10 [%] ~ 15 [%].
