Qhov sib txawv tseem ceeb ntawm Hysteresis thiab Eddy tam sim no poob yog tias hysteresis tam sim no poob tshwm sim vim qhov thim rov qab ntawm cov hlau nplaum, qhov eddy tam sim no poob tshwm sim vim kev txheeb ze ntawm tus neeg xyuas pib thiab cov hlau nplaum.
Nyob rau hauv lub transformer, muaj peev xwm muaj plaub yam kev poob tam sim no hu ua resistive poob, eddy tam sim no poob, flux poob, thiab hysteresis tam sim no poob. Cov hluav taws xob poob no tuaj yeem xaus rau thaum tshav kub uas yuav tsum tau muab tshem tawm ntawm lub transformer.
Hysteresis Tam sim no poob yog dab tsi?
Hysteresis tam sim no poob tshwm sim hauv cov khoom siv hluav taws xob vim yog cov hlau nplaum saturation hauv lawv cov tub ntxhais. Nyob rau hauv cov txheej txheem no, cov khoom sib nqus nyob rau hauv cov tub ntxhais nws thiaj li ua magnetically saturated thaum cov ntaub ntawv muab tso rau hauv ib tug muaj zog magnetic teb, xws li ib tug sib nqus teb uas yog generated los ntawm ib tug AC tam sim no.
Peb tuaj yeem piav qhia txog hysteresis tam sim no poob raws li hom hluav taws xob hauv cov tshuab hluav taws xob uas tshwm sim vim rov ua cov hlau nplaum thiab demagnetization ntawm cov tub ntxhais hlau. Qhov ntws ntawm qhov hloov pauv tam sim no ua rau cov tub ntxhais hlau tau hlau nplaum thiab demagnetized hauv txhua lub voj voog. Thaum txhua lub voj voog ntawm magnetization, qee lub zog poob.
Txhawm rau txo qhov poob ntawm lub zog no, peb tuaj yeem siv cov ntaub ntawv uas muaj tsawg dua rau lub voj hysteresis. Yog li ntawd, silica steel lossis CRGO steel yog qhov tseem ceeb hauv kev tsim cov tub ntxhais hauv lub tshuab hloov pauv vim nws muaj thaj tsam me me ntawm lub voj voog hysteresis.
Eddy Tam sim no poob yog dab tsi?
Eddy tam sim no poob tuaj yeem piav qhia raws li cov voj voog tam sim no tsim los ntawm tus neeg xyuas pib qhov chaw vim qhov hloov pauv sib nqus. Hom kev poob tam sim no tseem ceeb hauv induction cua sov, levitating, electromagnetic damping, thiab electromagnetic braking. Peb tuaj yeem txo qhov kev poob tam sim no los ntawm kev ntxiv cov slots rau tus neeg xyuas pib nto thiab laminating.
Daim duab 01: Laminated Core Eddy Current
Ib qho eddy tam sim no poob tshwm sim thaum qhov hloov pauv txuas nrog lub hauv paus nws tus kheej. Qhov induced emf no yog lub hauv paus uas tuaj yeem teeb tsa lub voj voog tam sim no hu ua Eddy tam sim no. Qhov tam sim no tuaj yeem tsim qhov poob hu ua eddy tam sim no poob lossis I2R poob. Ntawm no, nws yog tus nqi ntawm qhov tam sim no thiab R (tsis kam) ntawm txoj kev tam sim no.
Ntxiv mus, qhov loj ntawm eddy tam sim no tuaj yeem muab tau thaum lub eddy tam sim no "Kuv" ntws los ntawm txoj hauv kev tseem ceeb ntawm kev tiv thaiv "r," qhov twg nws tuaj yeem tawg lub zog hauv daim ntawv kub, uas tuaj yeem muab rau hauv lub zog sib npaug, lub zog=I2R. Qhov no sawv cev rau lub zog uas tau siv rau tsis muaj lub hom phiaj tseem ceeb, qhov uas nws suav tias yog qhov poob tam sim no lossis poob hlau.
Dab tsi yog qhov txawv ntawm Hysteresis thiab Eddy Tam Sim No Loss?
Qhov sib txawv tseem ceeb ntawm Hysteresis thiab Eddy tam sim no poob yog tias hysteresis tam sim no poob tshwm sim vim qhov thim rov qab ntawm cov hlau nplaum, qhov eddy tam sim no poob tshwm sim vim qhov txheeb ze ntawm tus neeg xyuas pib thiab cov hlau nplaum. Ntxiv mus, Hysteresis tam sim no poob tshwm sim vim molecular kev sib txhuam nyob rau hauv ib tug ferromagnetic khoom nyob rau hauv ib tug alternating magnetic teb thaum eddy tam sim no poob tshwm sim vim induction ntawm eddy tam sim no nyob rau hauv cov tub ntxhais thiab conductors tuav nyob rau hauv lub magnetic teb.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm Hysteresis thiab Eddy tam sim no poob hauv daim ntawv teev npe rau kev sib piv ntawm ib sab.
Summary – Hysteresis vs Eddy Tam Sim No Loss
Hysteresis tam sim no poob yog lub zog poob uas tshwm sim hauv lub tshuab hluav taws xob vim yog qhov sib nqus ntawm qhov sib nqus hauv cov tub ntxhais ntawm lub transformer, thaum eddy tam sim no poob yog tam sim no loops tsim los ntawm tus neeg xyuas pib qhov chaw vim yog hloov magnetic flux. Qhov sib txawv tseem ceeb ntawm Hysteresis thiab Eddy tam sim no poob yog tias hysteresis tam sim no poob tshwm sim vim qhov thim rov qab ntawm cov hlau nplaum, qhov eddy tam sim no poob tshwm sim vim qhov txheeb ze ntawm tus neeg xyuas pib thiab cov hlau nplaum.
