Vim li cas Transformer Cores siv Square Electrical Steel Phaj?

GNEE Hlau Hluav Taws Xob Hlau Phaj

Lub zog poob hauv cov tub ntxhais hlau muaj xws li "hysteresis poob" thiab "eddy tam sim no poob". Hysteresis poob yog lub zog siv los ntawm kev rov ua dua cov hlau nplaum hauv qhov chaw sib nqus sib nqus. Lub hysteresis poob ib chav tsev ntim yog proportional rau thaj tsam ntawm lub voj voog hysteresis thiab zaus f ntawm alternating magnetic teb (V yog qhov ntim ntawm cov hlau nplaum). Yog li ntawd, los ntawm kev xaiv cov khoom sib nqus nrog nqaim hysteresis loops, hysteresis poob ntawm cov tub ntxhais hlau tuaj yeem raug txo. Cov ntaub ntawv xws lihluav taws xob hlausiv nyob rau hauv transformers thiab motors muaj tsawg hysteresis poob.
Eddy tam sim no poob Lub alternating magnetic flux tsim ib tug induced electromotive quab yuam nyob rau hauv lub hlau core, ua circulating currents hu ua eddy currents, uas circulate nyob rau hauv ib tug dav hlau perpendicular mus rau magnetic flux. Lub zog poob los ntawm eddy tam sim no; Yog li ntawd, cov eddy tam sim no ntawm cov tub ntxhais hlau tuaj yeem raug txo los ntawm kev ua kom muaj zog ntawm cov tub ntxhais hlau. poob. Stacking nplooj ntawv ntawm hluav taws xob hlau insulated los ntawm ib tug hlau core tso cai rau eddy tam sim no mus los ntawm ib tug resistor raws ib tug luv luv eddy tam sim no txoj kev nyob rau hauv ib tug ntev, nqaim Circuit Court. Nyob rau tib lub sijhawm, silicon hauvsilicon hlautsub kom lub resistivity ntawm cov khoom thiab kuj plays lub luag hauj lwm nyob rau hauv txo eddy tam sim no.

Qhov laj thawj loj tshaj plaws rau kev xaiv cov tub ntxhais square hlau yog qhov yooj yim ntawm winding coils. Cov tub ntxhais hlau nrog cov duab no tuaj yeem raug mob cais ntawm lub tshuab thiab tom qab ntawd muab tso rau ntawm cov tub ntxhais hlau, uas tsim nyog rau kev tsim khoom loj hauv cov haujlwm tiag tiag. Tau kawg, cov tub ntxhais hlau nrog cov duab no Cov tub ntxhais tseem muaj qhov tsis zoo ntawm kev muaj cua sib txawv ntawm cov laminations, ua rau sib nqus flux to.
Qhov tseeb, kuj tseem muaj ib puag ncig hlau core. Hom hlau core no ncaj qha dov los ntawm hluav taws xob steel strips. Nws tsis muaj qhov sib txawv ntawm huab cua, qhov sib nqus me me thiab cov khoom sib nqus zoo dua li cov square. Txawm li cas los xij, vim nws cov teeb meem coil winding, nws tsis yooj yim rau kev siv tshuab thiab tsim khoom loj. Nws muaj tsawg daim ntawv thov thiab feem ntau yog siv rau precision tam sim no transformers (tsis zoo li lub hwj chim transformers, uas feem ntau yog siv rau kev ntsuas).
