Thawj Bingsen Kev Tswj Xyuas Kev Lag Luam
Inductance yog ib qho yam ntxwv ntawm lub cev hauv ib lub voj voog uas piav qhia txog seb cov khoom ntawm lub voj voog tiv thaiv kev hloov pauv ntawm tam sim no thiab tsim hluav taws xob li cas. Txhawm rau piav qhia txog lub tswv yim no kom meej thiab hauv cov lus yooj yim, cia peb tshawb nrhiav nws hauv ntau ntu:
1. Tam sim no thiab lub zog sib nqus
Ua ntej, nws yog ib qho tseem ceeb kom nkag siab tias thaum tam sim no hla dhau ib txoj hlua, nws tsim ib lub zog sib nqus. Qhov no yog lub hauv paus ntsiab lus ntawm electromagnetism. Lub zog ntawm lub zog sib nqus nyob ntawm qhov loj ntawm tam sim no: qhov loj dua tam sim no, qhov muaj zog dua lub zog sib nqus tsim.
2. Kev siv hluav taws xob los ua kom muaj zog
Tom ntej no, peb yuav qhia txog kev siv hluav taws xob los ua kom muaj hluav taws xob. Txoj cai lij choj ntawm Faraday ntawm kev siv hluav taws xob los ua kom muaj hluav taws xob qhia rau peb tias lub zog sib nqus uas hloov pauv tuaj yeem tsim hluav taws xob hauv cov xov hlau nyob ib puag ncig. Qhov no txhais tau tias yog tias koj muaj lub zog sib nqus thiab nws qhov kev hloov pauv, nws tuaj yeem "ua kom muaj hluav taws xob" lossis "ua rau muaj hluav taws xob" hauv cov xov hlau nyob ze.
3. Lub luag haujlwm ntawm inductance
Yog li, qhov inductance ua haujlwm li cas? Thaum koj muaj ib txoj hlua (xws li lub kauj) thiab siv hluav taws xob sab hauv, lub zog sib nqus yuav tsim tawm. Yog tias qhov tam sim no pib hloov (nce lossis txo), lub zog sib nqus nyob ib puag ncig nws kuj yuav hloov pauv. Raws li Faraday txoj cai, qhov kev hloov pauv ntawm lub zog sib nqus no yuav tsim lub zog hluav taws xob ntawm txoj hlua, uas sim ua kom cov tam sim no qub tsis hloov pauv. Qhov xwm txheej no yog qhov tshwm sim ntawm inductance.
Yog tias tam sim no nce ntxiv, tus inductor yuav tsim hluav taws xob rov qab, sim txo qhov tam sim no. Yog tias tam sim no txo qis, tus inductor yuav tsim hluav taws xob pem hauv ntej, sim ua kom tam sim no nce ntxiv. Yog vim li cas cov inductors qee zaum piav qhia tias yog "inertia" ntawm tam sim no, tiv thaiv kev hloov pauv ntawm tam sim no.
4. Coil thiab Inductance
Hauv kev siv ua haujlwm, txhawm rau kom ua rau muaj qhov cuam tshuam ntawm inductance, cov xov hlau feem ntau raug qhwv rau hauv cov duab ntawm cov kauj. Txhua txoj hlau hauv lub kauj yuav cuam tshuam rau ib leeg vim yog lub zog sib nqus uas tsim los ntawm cov kauj sib ze, uas yuav ua rau qhov inductance ntawm tag nrho cov kauj loj dua li ntawm tus neeg coj ncaj.
5. Daim Ntawv Thov
Cov inductors muaj ntau yam kev siv. Piv txwv li, hauv cov khoom siv fais fab, cov inductors tuaj yeem siv los ua kom cov hluav taws xob hloov pauv du; Hauv cov khoom siv sib txuas lus wireless, nws siv ua ke nrog cov capacitors los tsim cov voj voog oscillation uas tuaj yeem lim tawm cov teeb liab ntawm cov zaus tshwj xeeb.
(1) Lub lim dej fais fab
Cov inductors siv rau hauv cov hluav taws xob circuits, tshwj xeeb tshaj yog nyob rau hauv switching fais fab mov, kom du thiab voltage, txo suab nrov thiab spikes. Lawv yog siv los tswj cov suab nrov zaus siab thiab muab DC fais fab ruaj khov rau cov circuits.
(2) Kev Xaiv Lub Voj Voog Resonant thiab Zaus
Cov inductors thiab capacitors siv ua ke los tsim cov resonant circuits uas tuaj yeem xaiv lossis ua kom cov teeb liab nrov ntawm cov zaus tshwj xeeb. Qhov no tseem ceeb heev hauv cov khoom siv sib txuas lus wireless xws li xov tooj cua thiab xov tooj ntawm tes, vim nws tuaj yeem siv rau kev lim thiab kho zaus.
(3) Kev khaws cia thiab xa hluav taws xob
Cov inductors ua haujlwm ua cov khoom siv khaws cia lub zog hauv cov voj voog, tshwj xeeb tshaj yog hauv cov khoom siv fais fab pulse thiab cov ntawv thov khaws cia lub zog ib ntus. Hauv cov transformers, cov inductors yog siv los hloov lub zog ntawm ntau lub voj voog sib txawv los ntawm kev sib txuas sib nqus thiab tso cai rau kev hloov pauv ntawm cov voltage thiab tam sim no.
(4) Txwv kev tiv thaiv tam sim no thiab overcurrent
Hauv cov voj voog pib thiab muab hluav taws xob ntawm cov tshuab hluav taws xob, cov inductors tuaj yeem txwv qhov nrawm ntawm qhov nce tam sim no thiab qhov siab tshaj plaws tam sim no, yog li muab kev tiv thaiv overcurrent thiab tiv thaiv kev puas tsuaj ntawm lub voj voog.
(5) Kev ua cov teeb liab
Hauv kev ua cov teeb liab analog, cov inductors siv los lim cov teeb liab zaus siab, phim impedance, thiab cov teeb liab qeeb. Lawv yog cov uas siv ntau hauv ntau hom kev tsim lim.
(6) Kev cuam tshuam hluav taws xob (EMI)
Inductance siv los tswj thiab lim cov electromagnetic interference (EMI), uas tuaj yeem tiv thaiv suab nrov los ntawm kev nkag mus rau hauv lub voj voog thiab tseem tiv thaiv suab nrov los ntawm kev tawm ntawm lub voj voog, yog li zam kev cuam tshuam nrog lwm cov khoom siv
(7) Cov Sensors
Hauv qee cov thev naus laus zis sensor, inductors siv los ntes cov kev hloov pauv hauv cov teb sib nqus, uas tej zaum yuav muaj feem cuam tshuam nrog qhov chaw, qhov ceev, lossis lwm yam khoom siv.
(8) Kev kho qhov fais fab
Hauv cov tshuab hluav taws xob AC, cov inductors thiab cov capacitors siv ua ke los txhim kho qhov muaj zog, txo cov kev siv hluav taws xob reactive, thiab yog li txhim kho kev siv hluav taws xob zoo.
6. Chav ntsuas
Lub chav ntsuas ntawm inductance yog Henry (H), uas muab lub npe rau tus kws tshawb fawb Asmeskas Joseph Henry. Yog tias qhov inductance ntawm lub kauj yog 1 Henry, ces txhua zaus qhov tam sim no hloov pauv ntawm tus nqi ntawm 1 ampere ib ob, nws yuav tsim lub zog hluav taws xob ntawm 1 volt ntawm lub kauj.
kev xaus lus
Yog li, feem ntau, inductance yog ib yam ntxwv ntawm ib qho khoom uas tiv taus kev hloov pauv ntawm tam sim no los ntawm kev tsim kom muaj lub zog rov qab hauv cov khoom kom tiv thaiv kev hloov pauv sai ntawm tam sim no. Lub hauv paus ntsiab lus yooj yim no muaj ntau yam kev siv hauv kev siv tshuab hluav taws xob thiab kev tsim hluav taws xob, los ntawm kev lim dej fais fab yooj yim tshaj plaws mus rau kev kho zaus xov tooj cua nyuaj.
