Passive tivthaiv yog ib yam khoom siv hluav taws xob.Vim tias tsis muaj hluav taws xob nyob hauv nws, cov lus teb rau cov teeb liab hluav taws xob yog passive thiab mloog lus.Lub teeb liab hluav taws xob tsuas tuaj yeem dhau los ntawm cov khoom siv hluav taws xob raws li cov yam ntxwv tseem ceeb, yog li nws tseem hu ua passive tivthaiv.
Muaj peb yam tseem ceeb ntawm cov khoom siv passive: capacitor, inductor thiab resistor, uas yog cov khoom siv hluav taws xob yooj yim tshaj plaws.
Capacitor
Capacitors yog cov khoom siv hluav taws xob ntau tshaj plaws.Lawv khaws thiab tso tawm hluav taws xob hauv daim ntawv ntawm hluav taws xob zoo li qub.Lawv raug cais tawm ntawm cov khoom siv hluav taws xob ntawm ob tus ncej los ntawm kev tshaj tawm thiab khaws cov hluav taws xob hluav taws xob ntawm lawv.
Inductor
Inductor yog ib qho khoom siv uas tuaj yeem hloov hluav taws xob rau hauv lub zog sib nqus thiab khaws cia.Nws txoj hauv kev ua haujlwm yog tias thaum hloov pauv tam sim no dhau los ntawm cov hlau, alternating magnetic flux yog generated sab hauv thiab ib ncig ntawm cov hlau.Nws lub luag haujlwm tseem ceeb yog cais thiab lim cov teeb liab AC lossis tsim kev sib haum xeeb nrog cov capacitors thiab resistors.Inductors kuj tuaj yeem muab faib uatus kheej inductorthiab kev sib nrig sib inductor.
Tus kheej inductor
Thaum tam sim no hla lub kauj, ib qho chaw sib nqus yuav raug tsim nyob ib ncig ntawm lub kauj.Thaum qhov hloov pauv tam sim no, cov hlau nplaum nyob ib puag ncig nws kuj hloov raws li.Hloov magnetic teb tuaj yeem ua rau lub kauj nws tus kheej tsim induced electromotive force (induced electromotive force), uas yog nws tus kheej induction.
Cov khoom siv hluav taws xob uas muaj qee qhov kev hloov pauv thiab tuaj yeem tsim ib qho ntawm tus kheej inductance lossis kev sib nrig sib inductance feem ntau hu ua inductance coils.In thiaj li ua kom tus nqi inductance, txhim kho qhov zoo tshaj plaws thiab txo qhov ntim, cov tub ntxhais hlau lossis hlau nplaum yog Feem ntau ntxiv.Qhov tseem ceeb ntawm inductor muaj xws li inductance, zoo tshaj plaws, qhov muaj peev xwm, kev ruaj ntseg, tam sim no thiab ua haujlwm zaus.Cov inductor muaj li ntawm ib kauj yog hu ua tus kheej inductance, thiab nws tus kheej inductance tseem hu ua tus kheej inductance coefficient.
Kev sib nrig sib Inductor
Thaum ob lub inductive coils nyob ze rau ib leeg, qhov sib nqus teb hloov pauv ntawm ib qho inductive kauj yuav cuam tshuam rau lwm qhov inductive coil, uas yog kev sib nrig sib inductance.Qhov loj ntawm kev sib nrig sib inductance nyob ntawm seb qhov sib txuas ntawm tus kheej induction ntawm inductance coil thiab ob lub inductance coils.Cov khoom tsim los ntawm kev siv txoj cai no hu ua kev sib nrig sib inductor.
Resistor
Ib tug resistor yog ob lub davhlau ya nyob twg hluav taws xob ua los ntawm cov khoom siv hluav taws xob, uas muaj qee yam qauv thiab txwv tam sim no hauv Circuit Court.
Yog li, tus resistor tuaj yeem siv los ua cov khoom siv hluav taws xob los hloov hluav taws xob rau hauv lub zog sab hauv los ntawm kev tawm tsam ntawm electrons ntawm atoms.
Cov resistors feem ntau yog muab faib ua cov resistor ruaj khov, qhov sib txawv ntawm cov resistor thiab cov resistor tshwj xeeb (tsuas yog suav nrog cov resistor rhiab), ntawm cov khoom ruaj khov yog siv dav hauv cov khoom siv hluav taws xob.
Huizhou Mingda muaj 16 xyoo kev paub los ua txhua yam ntawm inductors.
Peb yog ib qho ntawm cov kws tshaj lij thiab cov chaw tsim khoom ntawm inductor hauv Suav teb.
