Lub hauv paus ntsiab lus ntawm inductor khaws cia hluav taws xob

Lub luag haujlwm tseem ceeb ntawm inductance yog khaws cov hloov pauv tam sim no (suav lub zog hluav taws xob hauv daim ntawv sib nqus), tab sis nws tsis tuaj yeem khaws cov tam sim no ncaj qha (ncaj tam sim no tuaj yeem dhau los ntawm inductor coil yam tsis muaj kev cuam tshuam).

Lub luag haujlwm tseem ceeb ntawm capacitance yog khaws cov tam sim no ncaj qha ( khaws cia hluav taws xob ncaj qha rau ntawm daim phiaj capacitor), tab sis nws tsis tuaj yeem khaws cov hloov tam sim no (alternating tam sim no tuaj yeem dhau los ntawm lub capacitor yam tsis muaj kev cuam tshuam).

Qhov tseem ceeb tshaj plaws inductance tau pom los ntawm tus kws tshawb fawb Askiv Faraday hauv xyoo 1831.

Cov ntawv thov yog ntau yam transformers, motors, thiab lwm yam.

Schematic daim duab ntawm Faraday kauj (Faraday kauj yog ib qho kev sib nrig sib inductance coil)

Lwm hom inductance yog tus kheej-inductance kauj

Xyoo 1832, Henry, tus kws tshawb fawb Asmeskas, tau luam tawm ib daim ntawv ntawm tus kheej qhov tshwm sim. Vim Henry txoj kev koom tes tseem ceeb hauv kev ua haujlwm ntawm tus kheej induction tshwm sim, tib neeg hu ua chav tsev ntawm inductance Henry, abbreviated li Henry.

Qhov tshwm sim ntawm tus kheej-induction yog ib qho tshwm sim uas Henry nrhiav tau thaum nws tab tom ua ib qho kev sim electromagnet. Thaum lub Yim Hli 1829, thaum lub tsev kawm ntawv so haujlwm, Henry tau kawm txog electromagnets. Nws pom tias lub coil tsim cov paj tsis tau xav txog thaum lub zog raug txiav. Nyob rau lub caij ntuj sov so ntawm xyoo tom ntej, Henry txuas ntxiv mus kawm cov kev sim uas cuam tshuam txog tus kheej-induction.

Thaum kawg, nyob rau hauv 1832, ib daim ntawv tau luam tawm los xaus lus tias nyob rau hauv ib co coil nrog tam sim no, thaum lub tam sim no hloov, ib tug induced electromotive quab yuam (voltage) yuav raug generated los tuav lub qub tam sim no. Yog li thaum lub zog hluav taws xob ntawm lub kauj raug txiav, qhov tam sim no txo ​​qis, thiab lub kauj yuav ua kom muaj hluav taws xob siab heev, thiab tom qab ntawd cov hluav taws xob Henry pom yuav tshwm sim (qhov hluav taws xob siab tuaj yeem ionize huab cua thiab luv-circuit los tsim sparks).

Self-inductance kauj

Faraday nrhiav tau qhov tshwm sim ntawm electromagnetic induction, lub ntsiab tseem ceeb ntawm uas yog qhov hloov magnetic flux yuav tsim induced electromotive quab yuam.

Stable ncaj tam sim no ib txwm txav mus rau hauv ib qho kev taw qhia. Nyob rau hauv lub voj kaw, nws tam sim no tsis hloov, yog li tam sim no ntws los ntawm lub kauj tsis hloov, thiab nws cov sib nqus flux yuav tsis hloov. Yog tias qhov sib nqus flux tsis hloov, tsis muaj qhov cuam tshuam electromotive quab yuam, yog li cov tam sim no ncaj qha tau yooj yim dhau los ntawm inductor coil yam tsis muaj kev cuam tshuam.

Hauv AC Circuit Court, qhov kev taw qhia thiab qhov loj ntawm qhov tam sim no yuav hloov raws sijhawm. Thaum AC hla dhau lub inductor kauj, raws li qhov loj thiab kev taw qhia ntawm tam sim no hloov, cov hlau nplaum sib nqus nyob ib ncig ntawm lub inductor tseem yuav hloov tsis tu ncua. Qhov kev hloov pauv hauv cov hlau nplaum sib nqus yuav ua rau lub zog ntawm cov hluav taws xob hluav taws xob, thiab lub zog hluav taws xob no tsuas yog cuam tshuam txoj hauv kev ntawm AC!

Tau kawg, qhov teeb meem no tsis tiv thaiv AC kom dhau 100%, tab sis nws ua rau qhov nyuaj ntawm AC hla dhau (impedance nce). Nyob rau hauv tus txheej txheem ntawm thaiv AC dhau, ib feem ntawm lub zog hluav taws xob hloov mus rau hauv daim ntawv ntawm magnetic teb thiab khaws cia rau hauv inductor. Qhov no yog lub hauv paus ntsiab lus ntawm inductor khaws cia hluav taws xob

Lub hauv paus ntsiab lus ntawm inductor khaws cia thiab tso hluav taws xob hluav taws xob yog txheej txheem yooj yim:

Thaum lub coil tam sim no nce - ua rau cov hluav taws xob nyob ib puag ncig hloov pauv - sib nqus flux hloov pauv - tsim rov qab induced electromotive quab yuam ( khaws cia hluav taws xob ) - thaiv qhov tam sim no los ntawm kev nce

Thaum lub coil tam sim no txo ​​qis-ua rau cov hluav taws xob nyob ib puag ncig hloov pauv-sib nqus flux hloov pauv-tsim tib yam kev coj ua rau lub zog hluav taws xob (tso tawm hluav taws xob) - thaiv qhov tam sim no los ntawm kev txo qis.

Nyob rau hauv ib lo lus, tus inductor yog ib tug conservative, ib txwm tuav lub qub lub xeev! Nws ntxub kev hloov pauv thiab ua haujlwm los tiv thaiv kev hloov pauv tam sim no!

Lub inductor zoo li AC dej reservoir. Thaum tam sim no nyob rau hauv Circuit Court loj, nws khaws ib feem ntawm nws, thiab thaum tam sim no me me, nws tso nws mus ntxiv!
