Kev xaiv thiab kuaj ntawm inductors

Kev xaiv ntawm inductors yuav tsum xav txog yam xws li lawv cov kev siv tshwj xeeb, kev ua haujlwm, kev xav tau ntawm Circuit Court, ib puag ncig, thiab tus nqi. Nyob rau hauv high-frequency circuits, nyiaj coated xov hlau yuav tsum tau siv los ua hollow coils los daws qhov "skin effect" ntawm high-frequency tam sim no; Txhawm rau ua kom cov inductance, cov khoom siv tuaj yeem xaiv tau raws li cov hlau nplaum sib nqus raws li kev ua haujlwm ntawm inductor, xws li siv cov khoom siv nickel zinc ferrite ntawm cov khoom siv siab.

Kev ntsuas qhov DC tsis kam ntawm ib qho inductor siv qhov "ohm" ntau yam ntawm multimeter tuaj yeem kuaj pom nws qhov zoo. Yog tias qhov ntsuas qhov ntsuas tsis zoo yog tsawg dua tus qauv ntsuas tus nqi ntawm tib lub inductance, nws qhia tau hais tias qhov tshwm sim luv luv hauv lub kauj. Qhov me me qhov ntsuas tsis kam, qhov loj dua qhov luv luv phenomenon. Yog hais tias qhov ntsuas tsis kam yog qhov loj thiab qhia tau tias tsis muaj kev tiv thaiv, nws qhia tau hais tias cov hlau sab hauv ntawm lub kauj tau tawg lawm.

Rau coils nrog ntau lub windings, ib tug multimeter yuav tsum tau siv los xyuas cov luv luv circuits thiab qhib circuits ntawm txhua winding. Rau cov coils nrog cov hlau nplaum sib nqus lossis cov hlau thaiv hlau, xyuas kom luv luv ntawm lawv cov coils thiab cov tub ntxhais hlau lossis hlau thaiv.

Tsis tas li ntawd, thaum siv inductors, cov teeb meem hauv qab no yuav tsum raug sau tseg.

Rau adjustable inductance coils nrog sib nqus cores, nws yuav tsum tau hais tias cov xov ntawm lub magnetic core fits zoo. Nws yuav tsum tig tau yooj yim yam tsis tau swb.

Kev puas tsuaj ntawm inductors feem ntau yog tshwm sim los ntawm kev quab yuam sab nraud ntau dhau los yog siv tsis zoo ib puag ncig, dampness, pwm, thiab corrosion. Thaum nws pom tias lub kauj tawg los yog muaj ntau yam luv luv, cov ntsiab lus vuam los yog cov chaw sib tw nquag ntawm lub qhov hluav taws xob coil yuav tsum tau kuaj xyuas ua ntej. Thaum siv cov coil inductive, nws yog ib qho tseem ceeb kom tsis txhob arbitrarily hloov nws cov duab thiab qhov kev ncua deb ntawm lub coils, vim hais tias qhov no yuav cuam tshuam rau inductance thiab zoo yam tseem ceeb ntawm lub kauj, ua rau nws tseem ceeb tshwj xeeb tshaj yog rau high-frequency inductive coils.

Thaum lub sij hawm kev teeb tsa ntawm ntau lub coils, qhov kev tso kawm ntawm txhua lub kauj yuav tsum ua tau raws li qhov yuav tsum tau ua kom txo qis kev cuam tshuam ntawm lawv. Piv txwv li, nyob rau hauv lub xov tooj cua receiver, lub kav hlau txais xov coil yuav tsum tau khaws cia ntawm ib tug deb ntawm qhov chaw ntawm lub intermediate zaus transformer, thiab ob hom sib nqus cores yuav tsum tau ntsia perpendicular rau ib leeg.
