Thermosetting plastic iphakeji ikhoyili electromagnetic QVT306

Yiziphi izici zepharamitha ye-inductance?

1. Ikhwalithi yesici sekhwalithi:

Isici sekhwalithi Q isici esisetshenziselwa ukukala ubudlelwano phakathi kwamandla agcinwe izinto zokugcina amandla (ama-inductors noma ama-capacitor) kanye nokusebenzisa kwawo amandla, achazwa ngokuthi: Q=2π umkhawulo wamandla agciniwe/ukulahlekelwa kwamandla kwamasonto onke. Ngokuvamile, inani elikhulu le-Q lekhoyili ye-inductance, lingcono, kodwa libe likhulu kakhulu lizokwenza ukuzinza kwesifunda esisebenzayo kubi nakakhulu.

2, I-Inductance:

Lapho i-current in ikhoyili ishintsha, ukuguquguquka kazibuthe okudlula ku-loop yekhoyili ngokwayo okubangelwa amandla ashintshile nakho kuyashintsha, okubangela ikhoyili ngokwayo ukuthi idonse amandla e-electromotive. I-self-inductance coefficient inani elibonakalayo elimele ikhono lokuzishintsha lekhoyili. Kubuye kubizwe nge-self-inductance noma inductance. Ivezwa uL. Ethatha uHenry (H) njengeyunithi, ingxenye eyinkulungwane yayo ibizwa ngokuthi millihenh (mH), ingxenye eyisigidi ibizwa ngokuthi millihenh (H), futhi ingxenye eyinkulungwane yayo ibizwa ngokuthi iNahen (NH).

3. I-DC Resistance(DCR):

Ekuhlelweni kwe-inductance, okuncane ukumelana kwe-DC, kungcono. Iyunithi yokulinganisa ithi ohm, ngokuvamile ephawulwa ngenani layo eliphezulu.

4, imvamisa ye-self-resonant:

I-Inductor ayiyona into e-inductive kuphela, kodwa futhi inesisindo somthamo osabalalisiwe. I-resonance kufrikhwensi ethile ebangelwa i-inductance engokwemvelo namandla asabalalisiwe e-inductor ngokwayo ibizwa ngokuthi i-self-harmonic frequency, eyaziwa nangokuthi i-resonance frequency. Ivezwe nge-SRF, iyunithi yi-megahertz (MHz).

5. Inani lokuphazamiseka:

Inani le-impedance le-inductor libhekisela enanini lakho konke ukuphazamiseka kwayo ngaphansi kwamanje (inombolo eyinkimbinkimbi), okuhlanganisa ukuxhumana nezingxenye ze-DC. Inani le-impedance lengxenye ye-DC liwukumelana kwe-DC kuphela kokusonga (ingxenye yangempela), futhi inani lokuvinjelwa kwengxenye yokuxhumana lihlanganisa ukusabela (ingxenye ecatshangelwayo) ye-inductor. Ngalo mqondo, i-inductor ingabuye ithathwe ngokuthi "i-resistor yokuxhumana". 6. Isilinganiso samanje: Ukuqina kwamanje kwe-DC okuqhubekayo okungadlula ku-inductor kuvunyelwe. Ukuqina kwamanje kwe-DC kusekelwe ekukhuphukeni okuphezulu kwezinga lokushisa kwe-inductor ezingeni lokushisa eliphakeme elingeziwe le-ambient. I-current eyengeziwe ihlobene nekhono le-inductor lokunciphisa ukulahleka kokusonta ngokumelana ne-DC okuphansi, futhi ihlobene nekhono le-inductor lokuhlakaza ukulahleka kwamandla asongayo. Ngakho-ke, i-current eyengeziwe ingathuthukiswa ngokunciphisa ukumelana ne-DC noma ukwandisa isikali se-inductance. Kumagagasi amanje anefrikhwensi ephansi, impande yawo isho inani lamanje eliyisikwele
