Silicon hlau hauv Transformers

Lub ntsiab ntawm lub transformer yog cov hlau core thiab windings. Cov tub ntxhais feem ntau yog ua los ntawm laminated silicon steel los xij. Nrog rau cov ntsiab lus silicon li ntawm 0.8% mus rau 4.8%, lawv muaj zog sib nqus permeability.

Ua ntej- txiav cov ntawv silicon steel

Thaum lub transformer ua haujlwm, nws ua rau lub zog xa hluav taws xob poob. Muaj ob hom kev poob loj: ib qho yog tooj liab poob, uas tshwm sim vim qhov tsis kam ntawm windings; thiab lwm yam hlau poob, uas originates nyob rau hauv lub silicon steel los xij. Hlau poob nws tus kheej yog tshwm sim los ntawm ob lub ntsiab tshwm sim: hysteresis poob thiab eddy tam sim no poob.

 

transformer hysteresis nkhaus

Hysteresis poob yog cov hlau poob uas tshwm sim vim qhov tshwm sim hysteresis thaum lub sij hawm magnetization txheej txheem ntawm cov tub ntxhais hlau. Qhov loj ntawm qhov kev poob no yog ncaj qha proportional rau thaj tsam ntawm cov khoom siv lub voj hysteresis. Silicon steel muaj lub vojvoog hysteresis, yog li siv nws rau lub transformer core ua rau me me hysteresis poob.

 

Transformer eddy-tam sim no poob

Eddy tam sim no poob yog tshwm sim los ntawm circulating currents induced nyob rau hauv cov khoom tseem ceeb los ntawm alternating magnetic flux. Cov dej ntws no ntws hauv cov dav hlau perpendicular mus rau magnetic flux thiab kuj ua rau cov cua sov tsim. Txhawm rau txo qhov kev poob no, cov tub ntxhais hlau yog tsim los ntawm laminated silicon steel los xij, uas ua rau kom muaj kev tiv thaiv nyob rau hauv txoj kev ntawm eddy tam sim no.

 

 

Silicon steel los xij txiav txim siab lub zog poob ntawm lub transformer. Raws li tau hais los saum no, lawv qhov loj thiab cov duab yog qhov tseem ceeb uas cuam tshuam rau lub zog poob. Raws li txoj cai, lub thinner cov ntaub ntawv silicon steel thiab qhov nqaim ntawm laminated strips, qhov zoo dua cov nyhuv. Txawm li cas los xij, qhov ua tau zoo ntawm lamination thiab qhov ua tau zoo hla -section kuj yuav tsum tau txiav txim siab. Feem ntau, transformer cores siv txias- dov silicon steel los xij, feem ntau nyob rau hauv "E" lossis "I" zoo, nrog cov qauv tuab ntawm 0.35mm.

Core rau Roj Immersed Transformers

Transformers ua haujlwm ntawm lub hauv paus ntsiab lus ntawm electromagnetic induction. Ob lub windings, ib qho tseem ceeb thiab theem nrab, raug mob nyob ib puag ncig ntawm lub hauv paus hlau kaw. Thaum ib qho hluav taws xob hloov pauv tau siv rau lub hauv paus winding, alternating tam sim no ntws los ntawm nws, tsim kom muaj zog magnetomotive (MMF). Qhov MMF no tsav qhov sib nqus sib nqus sib nqus los ntawm cov tub ntxhais silicon steel.

Raws li Lenz txoj cai, qhov sib nqus flux uas tsim los ntawm qhov induced tam sim no yuav tawm tsam qhov kev hloov pauv ntawm qhov qub sib nqus flux. Thaum thawj qhov sib nqus flux nce, qhov sib nqus flux uas tsim los ntawm qhov cuam tshuam tam sim no tawm tsam nws, thiab qis dua - qib hloov hluav taws xob tshwm sim hauv qhov thib ob winding.

A. Tsawg hlau poob.Qhov no yog qhov taw qhia tseem ceeb tshaj plaws ntawm kev ua tau zoo. Cov txheej txheem thoob ntiaj teb faib cov qhab nia feem ntau raws li cov txiaj ntsig ntawm kev poob hlau. Qhov qis hlau poob, qib siab dua thiab qhov zoo dua.

B. Siab sib nqus induction.Silicon steel los xij uas tuaj yeem ua tiav qhov sib nqus sib nqus ntau dua nyob rau hauv tib qhov chaw sib nqus yuav ua rau cov cores me thiab sib dua. Qhov no, nyob rau hauv lem, txuag silicon steel, tooj liab hlau, thiab insulating cov ntaub ntawv.

C. High stacking factor.Smooth, tiaj tus thiab cov tuab tuab hauv cov ntaub ntawv silicon steel txhim kho cov ntim ntom ntom ntawm cov tub ntxhais. Qhov no ua rau muaj kev nce hauv qhov chaw ua haujlwm thiab kev ua haujlwm sib nqus.

D. Kev ua haujlwm zoo punching.Cov cuab yeej no yog qhov tseem ceeb tshwj xeeb rau kev tsim cov cores siv hauv cov tshuab me me thiab micro.

E. Zoo adhesion thiab weldability ntawm qhov chaw rwb thaiv tsev txheej.Cov txheej txheem insulating ruaj khov uas ua tau zoo thiab tso cai rau kev txhim kho vuam yog qhov tseem ceeb rau kev sib dhos thiab kev ua haujlwm.

F. Sib nqus aging kuj.Cov khoom siv yuav tsum muaj cov khoom sib nqus ruaj khov nyob rau lub sijhawm thiab nyob rau hauv kev ua haujlwm nyuaj.

G. Yuav tsum tau xa tuaj.Silicon steel los xij yuav tsum tau muab tom qab annealing thiab pickling txheej txheem los xyuas kom meej cov hlau nplaum zoo thiab txhua yam khoom.
