Kab lus no yuav ua tib zoo teb cov lus nug no, txheeb xyuas cov ntsiab lus tseem ceeb uas xav tau kev saib xyuas thaum siv inductors, muab kev cob qhia thiab cov tswv yim, thiab pab koj siv inductors muaj kev nyab xeeb thiab ua tau zoo, ua kom ruaj khov ntawm koj cov khoom siv hluav taws xob.

1. Txheeb xyuas qhov tseem ceeb ua ntej siv kom tsis txhob muaj qhov tsis sib xws

Ua ntej txhim kho thiab siv lub inductor, thawj kauj ruam thiab tseem ceeb tshaj plaws yog los xyuas seb nws qhov tseem ceeb tsis haum rau cov kev cai hauv Circuit Court. Kev siv cov inductor nrog qhov tsis sib xws yog qhov ua rau muaj kev puas tsuaj ntau tshaj plaws thiab kev ua haujlwm tsis zoo. Cov yam ntxwv tseem ceeb uas yuav tsum tau tsom rau suav nrog tus nqi inductance, ntsuas tam sim no, DC tsis kam (DCR), ua haujlwm zaus, thiab ntsuas kub.

Ua ntej, tus nqi inductance ncaj qha txiav txim siab qhov inductor kev ua haujlwm hauv lub zog cia, txwv tam sim no, thiab lim. Yog tias tus nqi inductance raug xaiv siab dhau lossis qis dhau, nws yuav ua tsis tau raws li qhov yuav tsum tau ua hauv Circuit Court -piv txwv li, inductor nrog tus nqi inductance qis heev hauv lub zog hluav taws xob tsis tuaj yeem lim tawm tam sim no ripple, ua rau cov zis tsis ruaj khov; thaum tus nqi inductance ntau dhau yuav ua rau lub cev muaj zog impedance, cuam tshuam rau qhov tam sim no ntws, thiab txawm ua rau lub voj voog tsis pib. Nws raug nquahu kom siv tus kws tshaj lij inductance tester txhawm rau txheeb xyuas tus nqi inductance ua ntej siv, xyuas kom meej tias nws nyob hauv qhov kam rau ua tau teev tseg los ntawm tus tsim (feem ntau ± 5% lossis ± 10%).

Qhov thib ob, qhov ntsuas tam sim no yog qhov tseem ceeb tsis tuaj yeem tsis quav ntsej. Txhua inductor muaj qhov siab tshaj plaws tam sim no nws tuaj yeem tiv taus ntev; Tshaj qhov tam sim no yuav ua rau lub inductor qhov kub thiab txias nce siab, ua rau cov rwb thaiv tsev laus, winding burnout, los yog luv luv circuits. Hauv kev siv tswv yim, nws yog ib qho tsim nyog los xyuas kom meej tias qhov ua haujlwm tam sim no ntawm inductor tsis tshaj nws qhov ntsuas tam sim no, thiab nws yog qhov zoo tshaj plaws kom khaws cia 10% -20% kev nyab xeeb, tshwj xeeb tshaj yog nyob rau hauv high-power circuits lossis circuits nrog kev hloov pauv tam sim no. Piv txwv li, nyob rau hauv automotive electronic circuits, qhov chaw ua hauj lwm ib puag ncig yog complex thiab tam sim no hloov drastic, xaiv ib tug inductor nrog ib tug siab rated tam sim no tshaj qhov tiag tiag ua hauj lwm tam sim no yuav ua tau kom tsis txhob muaj kev puas tsuaj los ntawm tam sim no surges.

Tsis tas li ntawd, DC tsis kam (DCR) thiab kev ua haujlwm zaus kuj yuav tsum tau kuaj xyuas. DCR ntawm inductor cuam tshuam rau kev siv hluav taws xob ntawm lub voj voog; DCR siab dua yuav ua rau kom tsis muaj zog thiab ua rau tsis muaj cua sov. Kev ua haujlwm zaus ntawm cov inductor yuav tsum sib haum rau kev khiav hauj lwm zaus ntawm lub Circuit Court - siab - zaus inductors yog tsim los ua hauj lwm nyob rau hauv high- zaus circuits (sab saum toj 1MHz), thaum qis - zaus inductors yog haum rau qis -frequency scenarios 1 MHz (berequency scenarios). Kev siv qhov tsawg- zaus inductor nyob rau hauv siab - zaus Circuit Court yuav ua rau lub zog loj poob, overheating, thiab tsis ua hauj lwm sai.

2. Ua tib zoo saib xyuas kev tiv thaiv ib puag ncig los tiv thaiv kev puas tsuaj los ntawm cov xwm txheej sab nraud

Qhov chaw ua haujlwm ntawm inductors muaj qhov cuam tshuam loj rau lawv lub neej kev ua haujlwm thiab kev ua haujlwm. Ntau tus inductors ua tsis tau vim lawv tus kheej cov teeb meem zoo, tab sis vim yog kev tiv thaiv tsis raug rau ib puag ncig. Cov yam tseem ceeb ntawm ib puag ncig uas yuav tsum tau them nyiaj rau suav nrog kub, av noo, plua plav, thiab hluav taws xob cuam tshuam (EMI).

Kub yog qhov tseem ceeb tshaj plaws ntawm ib puag ncig cuam tshuam rau kev ua haujlwm inductor. Inductors rhiab heev rau qhov kub thiab txias; ntev - lub sijhawm ua haujlwm nyob rau hauv qhov chaw siab - qhov kub thiab txias yuav ua rau kev laus ntawm cov txheej txheem rwb thaiv tsev winding, txo qhov sib nqus permeability ntawm cov tub ntxhais hlau nplaum, thiab tseem ua rau cov tub ntxhais sib nqus kom deform lossis winding kom yaj. Ntau hom inductors muaj qhov ntsuas kub sib txawv-piv txwv li, chip inductors feem ntau muaj qhov ntsuas kub ntawm -40℃txog 125 degree, thaum lub zog inductors tuaj yeem tiv taus qhov kub siab dua (txog 150℃hauv qee kis). Hauv kev siv, nws yog ib qho tsim nyog los xyuas kom meej tias qhov ntsuas kub nyob ib puag ncig ntawm lub inductor tsis tshaj nws qhov ntsuas kub, thiab zam kev txhim kho cov inductor nyob ze ntawm qhov siab -cov khoom siv hluav taws xob (xws li cov resistors, diodes, lossis cov chips fais fab). Nyob rau tib lub sijhawm, cov cua kub zoo yuav tsum tau ua kom ntseeg tau- rau cov tshuab hluav taws xob siab, cov dab dej kub tuaj yeem ntsia tau lossis cov qhov cua tuaj yeem khaws cia kom txo tau cov cua sov.

Cov av noo yog lwm qhov tseem ceeb uas tsis tuaj yeem tsis quav ntsej. Cov dej noo nkag mus rau hauv inductor yuav ua rau corrosion ntawm winding (tshwj xeeb tshaj yog tooj liab windings), txo cov rwb thaiv tsev kev ua tau zoo, thiab tseem ua rau luv luv circuits ntawm windings. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv qhov chaw ntub dej xws li thaj chaw ntug dej hiav txwv, cov nroj tsuag tshuaj, lossis cov khoom siv sab nraum zoov. Txhawm rau tiv thaiv kom tsis txhob ya raws, nws raug nquahu kom xaiv cov inductors nrog cov dej tsis muaj dej lossis cov dej noo- cov ntaub ntawv pov thawj (xws li epoxy- kaw inductors) hauv qhov chaw ntub dej. Tsis tas li ntawd, thaum khaws cia thiab siv, tsis txhob muab cov inductor tso rau hauv qhov chaw ntub dej, thiab ua kom qhov chaw ua haujlwm qhuav. Yog hais tias tus inductor yog damp, nws yuav tsum tau qhuav kom huv si ua ntej siv kom tsis txhob muaj corrosion.

Plua plav thiab impurities tuaj yeem cuam tshuam rau kev ua haujlwm ntawm inductors. Ib tug loj npaum li cas ntawm cov plua plav tsub kom nyob rau saum npoo ntawm inductor yuav thaiv tshav kub dissipation, ua rau overheating; yog tias cov plua plav nkag mus rau qhov sib txawv ntawm cov winding thiab cov hlau nplaum, nws yuav ua rau muaj kev sib cuag tsis zoo lossis luv luv. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tsis tu ncua ntxuav qhov chaw ntawm inductor, ua kom qhov chaw ua haujlwm huv si, thiab tsis txhob muaj plua plav. Rau inductors siv nyob rau hauv ib puag ncig hnyav (xws li kev cob qhia kev lag luam nrog cov plua plav ntau), cov ntaub thaiv npog tuaj yeem ntsia tau los tiv thaiv cov plua plav nkag.

Electromagnetic cuam tshuam (EMI) kuj yog ib qho tseem ceeb uas xav tau kev saib xyuas. Inductors lawv tus kheej tsim ib qho chaw sib nqus thaum lub sijhawm ua haujlwm, thiab sab nraud muaj zog hlau nplaum yuav cuam tshuam nrog kev ua haujlwm ntawm inductors, ua rau muaj kev hloov pauv hauv inductance tus nqi thiab kev ua haujlwm tsis ruaj khov. Hauv kev siv, nws yog ib qho tsim nyog yuav tsum khaws cov inductors kom deb ntawm qhov chaw muaj zog sib nqus (xws li hlau nplaum, transformers, lossis motors). Nyob rau tib lub sijhawm, kev teeb tsa tsim nyog ntawm lub voj voog tuaj yeem txo qis kev cuam tshuam ntawm inductors thiab lwm yam khoom siv -piv txwv li, tsis txhob tso ntau lub inductors ze rau ib leeg, thiab npaj cov windings ntawm inductors nyob rau hauv tib txoj kev kom txo tau magnetic teb cuam tshuam.

3. Txhim kho kev txhim kho thiab kev ua haujlwm kom tsis txhob muaj kev puas tsuaj rau cov tshuab thiab hluav taws xob

Kev txhim kho thiab kev ua haujlwm tsis raug yog qhov tseem ceeb rau kev puas tsuaj rau inductor. Thaum lub sij hawm installation thiab siv, nws yog tsim nyog los ua raws li cov txheej txheem kev khiav hauj lwm cov txheej txheem kom tsis txhob muaj kev puas tsuaj thiab hluav taws xob puas inductor.

Nyob rau hauv cov nqe lus ntawm mechanical installation, nws yog ib qho tsim nyog kom tsis txhob muaj zog ntau dhau. Inductors (tshwj xeeb tshaj yog nti inductors thiab toroidal inductors) muaj cov qauv tsis yooj yim; Kev quab yuam ntau dhau thaum lub sijhawm teeb tsa tuaj yeem ua rau cov tub ntxhais hlau nplaum tawg, lub tshuab ua kom tawg, lossis cov pins kom khoov thiab tawg. Thaum txhim kho nti inductors ntawm PCBs, siv qhov tsim nyog soldering kub thiab lub sij hawm - kub soldering ntau heev (dhau 260 degree) los yog ntev soldering lub sij hawm (ntau tshaj 3 vib nas this) yuav ua puas lub inductor lub ntim thiab cov qauv sab hauv. Rau los ntawm - qhov inductors, thaum muab tso rau hauv PCB, tsis txhob khoov tus pins ntau dhau, thiab xyuas kom meej tias cov pins tau ruaj khov los tiv thaiv kev sib cuag tsis zoo vim xoob soldering.

Tsis tas li ntawd, nws yog ib qho tsim nyog kom tsis txhob muaj kev vibration thiab cuam tshuam. Inductors siv hauv cov khoom siv txawb (xws li cov khoom siv hluav taws xob hauv tsheb, cov khoom siv nqa tau) feem ntau raug kev co; ntev - lub sij hawm vibration yuav ua rau lub winding kom loosen, lub magnetic core hloov, los yog tus pins poob. Yog li ntawd, nws raug nquahu kom xaiv cov inductors nrog kev tiv thaiv- kev co tsim (xws li cov pins txhawb zog, poob siab- nqus ntim) hauv cov xwm txheej zoo li no, thiab xyuas kom meej tias cov inductor ruaj khov thaum lub sijhawm teeb tsa los txo qhov cuam tshuam ntawm kev co.

Hais txog kev ua haujlwm hluav taws xob, tus yuam sij yog kom tsis txhob overvoltage, overcurrent, thiab tam sim no hloov tam sim no. Kev hloov pauv tam sim no yuav ua rau muaj qhov loj loj -electromotive force (EMF) hauv inductor, uas tuaj yeem tshaj qhov hluav taws xob rwb thaiv tsev ntawm inductor thiab ua rau rwb thaiv tsev tawg. Piv txwv li, nyob rau hauv circuits uas nquag hloov (xws li hloov cov khoom siv hluav taws xob), nws yog ib qho tsim nyog yuav tsum tau ntxiv ib lub clamp diode los yog ib lub voj voog snubber kom nqus cov txee -electromotive force, tiv thaiv cov inductor thiab lwm yam khoom. Nyob rau tib lub sijhawm, tsis txhob nquag nyob ntawm - tawm ntawm lub voj voog hauv lub sijhawm luv luv, uas yuav ua rau muaj kev cuam tshuam ntau dua rau cov inductor thiab ua rau nws cov laus dua.

Nws tseem yog ib qho tseem ceeb kom tsis txhob rov qab kev sib txuas ntawm inductor (rau inductors nrog polarity, xws li qee lub zog inductors thiab txuas inductors). Kev sib txuas rov qab yuav tsis tsuas yog ua tsis tau raws li qhov xav tau hauv Circuit Court tab sis kuj tseem tuaj yeem ua rau inductor overheat thiab puas, lossis tseem cuam tshuam rau kev ua haujlwm ntawm tag nrho cov circuit. Ua ntej kev teeb tsa, nws yuav tsum tau kuaj xyuas lub cim polarity ntawm lub inductor thiab xyuas kom meej tias nws txuas tau raug raws li kev tsim hluav taws xob.

4. Kev tshuaj xyuas tsis tu ncua thiab kev saib xyuas kom ntev rau kev pab cuam lub neej

Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua yog qhov tseem ceeb los xyuas kom meej tias kev ua haujlwm ruaj khov ntawm inductors thiab txuas ntxiv lawv lub neej kev pab cuam. Rau cov khoom siv hluav taws xob uas tau ua haujlwm ntev - lub sijhawm ua haujlwm, nws raug nquahu kom tsim cov phiaj xwm tshuaj xyuas tsis tu ncua txhawm rau txheeb xyuas cov inductor qhov xwm txheej raws sijhawm thiab daws cov teeb meem tshwm sim.

Cov ntsiab lus ntawm kev tshuaj xyuas tsis tu ncua suav nrog cov hauv qab no: Ua ntej, txheeb xyuas qhov zoo li ntawm inductor -Saib seb lub ntim puas zoo li qub, puas muaj kev puas tsuaj, deformation, los yog tsis muaj xim (discoloration feem ntau qhia tias overheating), seb cov pins yog xoob, corroded, los yog tawg. Yog tias pom ib qho ntawm cov xwm txheej no, lub inductor yuav tsum tau hloov lub sijhawm kom tsis txhob cuam tshuam rau lub voj voog.

Qhov thib ob, ntsuas qhov tseem ceeb ntawm cov inductor tsis tu ncua. Siv tus kws tshaj lij los kuaj xyuas tus nqi inductance, DC tsis kam, thiab kev ua haujlwm rwb thaiv tsev ntawm inductor, thiab muab piv nrog cov khoom qub. Yog tias muaj qhov sib txawv tseem ceeb (xws li tus nqi inductance hloov ntau dua 10%, lossis DC tsis kam nce ntxiv), nws qhia tau tias inductor puas lawm lossis laus thiab yuav tsum tau hloov.

Thib peb, ntxuav lub inductor tsis tu ncua. Raws li tau hais ua ntej, cov plua plav tsub zuj zuj yuav cuam tshuam rau cov cua sov dissipation thiab ua rau overheating. Siv cov txhuam mos los yog cov cua compressed los ntxuav qhov chaw ntawm inductor thiab cov cheeb tsam ib puag ncig, tshem tawm cov plua plav thiab impurities, thiab xyuas kom zoo cua sov dissipation. Rau inductors nrog cov av loj, koj tuaj yeem siv me me ntawm anhydrous ethanol los so, tab sis tsis txhob siv cov tshuaj ntxuav corrosive, uas yuav ua rau lub inductor lub ntim thiab rwb thaiv tsev txheej.

Tsis tas li ntawd, rau cov inductors siv nyob rau hauv ib puag ncig hnyav (xws li kub, high humidity, los yog siab plua plav), kev soj ntsuam zaus yuav tsum tau nce kom tsim nyog, thiab cov inductor yuav tsum tau hloov tsis tu ncua raws li kev pab cuam lub neej los xyuas kom meej stability ntawm lub Circuit Court. Feem ntau, kev pab cuam lub neej ntawm inductors yog 5-10 xyoo nyob rau hauv kev siv ib txwm siv, tab sis nyob rau hauv ib puag ncig hnyav, lub neej kev pab cuam yuav luv luv mus rau 2-3 xyoos, yog li yuav tsum tau hloov tsis tu ncua.

5. Kev nkag siab tsis meej thiab kev daws teeb meem thaum siv inductors
