Dab tsi yog AL tus nqi ntawm cov tub ntxhais sib nqus xa mus rau

Sib Nqus Core yog ib qho khoom siv hluav taws xob siv los khaws thiab ua cov cim digital lossis analog teeb liab. Nws yog tsim los ntawm cov khoom sib nqus nrog cov hlau nplaum siab permeability thiab qis hysteresis poob, thiab yog siv dav hauv kev lag luam xws li khoos phis tawj thiab kev sib txuas lus. Hauv kev txhim kho cov cuab yeej siv hluav taws xob, cov hlau nplaum hlau nplaum yog ib qho ntawm cov khoom siv loj tshaj plaws thiab ceev tshaj plaws.

Dab tsi yog tus nqi ntawm cov tub ntxhais sib nqus xa mus rau

Tus nqi AL ntawm cov tub ntxhais sib nqus yog hais txog qhov sib txuam ntawm txoj kab nqes ntawm cov khoom siv hlau nplaum, uas yog lub zog hlau nplaum uas xav tau rau kev hloov pauv hauv magnetic flux ntom ntawm ib chav tsev ntev. Nws yog ib qho tseem ceeb ntawm cov ntaub ntawv qhia txog kev ua haujlwm ntawm cov hlau nplaum sib nqus, uas tuaj yeem cuam tshuam qhov sib nqus permeability thiab saturation yam ntxwv ntawm cov khoom siv hlau nplaum.

Qhov loj dua tus nqi AL, qhov sib nqus flux ntau dua qhov sib nqus core tuaj yeem tiv taus tib lub sijhawm ntev, ua rau muaj qhov sib nqus permeability ntau dua thiab cov yam ntxwv zoo sib nqus saturation. Yog li ntawd, thaum xaiv cov hlau nplaum sib nqus, nws yuav tsum xaiv qhov tsim nyog AL tus nqi raws li cov ntawv thov tshwj xeeb los xyuas kom meej tias cov tub ntxhais sib nqus tuaj yeem ua haujlwm ib txwm thiab ua haujlwm ruaj khov.

2. Kev sib raug zoo ntawm tus nqi ntawm magnetic cores thiab magnetic permeability

Muaj qee qhov kev sib raug zoo ntawm AL tus nqi thiab sib nqus permeability ntawm cov tub ntxhais hlau nplaum, thiab ob qho tib si yog cov cim qhia zoo sib xws. Sib nqus permeability yog lub peev xwm ntawm cov khoom siv los teb rau hauv magnetic teb, sawv cev rau qhov kev faib ua feem ntawm cov kev hloov pauv hauv cov hlau nplaum sib nqus nrog cov kev hloov hauv lub zog magnetic.

Qhov AL tus nqi ntawm cov tub ntxhais sib nqus tuaj yeem cuam tshuam nws qhov sib nqus permeability, uas yog, qhov siab dua AL tus nqi, qhov siab dua qhov sib nqus permeability ntawm cov tub ntxhais, uas yog, qhov loj dua qhov sib nqus flux uas tuaj yeem haum rau ib chav tsev ntev. Yog li, feem ntau hais lus, thaum xaiv cov tub ntxhais sib nqus, nws yog ib qho tsim nyog yuav tsum xaiv qhov tsim nyog AL tus nqi thiab sib nqus permeability raws li cov ntawv thov tshwj xeeb los xyuas kom meej tias cov tub ntxhais sib nqus tuaj yeem ua haujlwm ib txwm thiab ua haujlwm ruaj khov.

Tsis tas li ntawd, hauv kev siv cov tswv yim, AL tus nqi ntawm cov tub ntxhais hlau nplaum kuj tseem cuam tshuam los ntawm cov yam ntxwv xws li qhov kub thiab txias AC magnetic teb, thiab yuav tsum tau kho thiab siv qhov tsim nyog raws li qhov xwm txheej tiag tiag. Lub caij no, vim muaj qhov sib nqus zoo permeability thiab saturation yam ntxwv ntawm cov tub ntxhais hlau nplaum, yuav tsum tau them nyiaj kom tsis txhob overheating lossis overload thaum lub sij hawm thov kom tsis txhob muaj kev puas tsuaj los yog kev ua haujlwm ntawm cov hlau nplaum.

Zuag qhia tag nrho, AL tus nqi ntawm cov tub ntxhais sib nqus yog ib qho tseem ceeb ntawm cov cim qhia rau nws qhov kev ua tau zoo, uas tuaj yeem cuam tshuam nws qhov sib nqus permeability thiab cov yam ntxwv sib nqus saturation. Thaum xaiv cov hlau nplaum sib nqus, nws yuav tsum xaiv qhov tsim nyog AL tus nqi thiab sib nqus permeability raws li cov ntawv thov tshwj xeeb, thiab ua tib zoo saib xyuas kom tsis txhob overheating lossis overload, thiaj li ua kom muaj kev ua haujlwm zoo thiab ruaj khov ntawm cov hlau nplaum.
