Transformer Inrush tam sim no
Transformer inrush tam sim noyog ib ntus tam sim no surge uas yuav tshwm sim thaum lub transformer yog energized.
Lub transformer core yog ncaj qha koom nyob rau hauv no phenomenon.
Ntawm energization, cov sib nqus flux nyob ntawm qhov hloov pauv ntawm AC voltage waveform thiab cov seem flux seem hauv cov tub ntxhais.
Yog tias cov xwm txheej tsis zoo, qhov tshwm sim flux tuaj yeem ua ntau dua li nws qhov kev ua haujlwm ib txwm muaj. Cov tub ntxhais yuav ces nkag mus rau magnetic saturation, ua rau ib tug loj heev magnetizing tam sim no.
Ntau yam cuam tshuam rau transformer inrush tam sim no:
| Qhov xwm txheej | Kev npam |
| Hloov taw tes | Txiav txim siab qhov pib flux |
| Residual flux | Muaj peev xwm ntxiv rau qhov tshiab tsim flux |
| Cov khoom siv tseem ceeb | Muaj feem xyuam rau cov yam ntxwv saturation |
| Transformer tsim | Txiav txim siab ib txwm sib nqus ua haujlwm |
| Qhov system impedance | Influences qhov tshwm sim tam sim no |
| Winding configuration | Muaj peev xwm cuam tshuam tus cwj pwm tsis zoo |
Rau cov transformers loj, inrush tam sim no yuav tsum tau ua tib zoo txiav txim siab thaum teeb tsa kev tiv thaiv.
Piv txwv li, kev tiv thaiv transformer sib txawv yuav tsum paub qhov txawv ib ntus magnetizing inrush los ntawm qhov ua txhaum ntawm sab hauv. Txwv tsis pub, lwm yam kev noj qab haus huv transformer yuav tsis tsim nyog tripped thaum lub zog.
Transformer Noise
Transformer suab nrovyog lwm tus yam ntxwv tseem ceeb uas muaj kev sib raug zoo nrog lub hauv paus.
Lub suab humming paub los ntawm lub zog transformer feem ntau yog txuam nrogmagnetostrictionthiab electromagnetic rog nyob rau hauv lub hauv paus.
Txawm li cas los xij, lub hauv paus tsis yog tib lub peev xwm ntawm lub suab. Cov kiv cua txias, roj twj, lub tank vibration, winding vibration, thiab lwm yam khoom siv tshuab kuj tuaj yeem pab txhawb.
Ua rau Transformer Noise
Lub hauv paus ntsiab lus ntawm lub suab nrov yog magnetostriction.
Thaum cov hlau nplaum hloov pauv, cov hlau nplaum hlau tau hloov pauv me me. Cov kev hloov pauv no tshwm sim ntau zaus nrog cov sib nqus sib nqus thiab tsim cov tshuab kev co.
Cov kev vibration tuaj yeem raug xa mus rau cov tub ntxhais clamping qauv, tank, thiab lwm yam khoom.
Rau cov transformers loj, txo suab nrov yog li ntawd yuav tsum tau ntau tshaj qhov tsuas yog xaiv ib tug tsawg- suab nrov magnetic steel. Kev tsim cov hlau nplaum thiab mechanical yuav tsum tau txiav txim siab tag nrho.
Ob peb yam cuam tshuam rau Transformer Noise Level
Lub suab nrov ntawm Transformer cuam tshuam los ntawm ntau yam, suav nrog cov hlau nplaum hlau, core magnetic flux ntom, kev sib koom ua ke, clamping quab yuam, tank tsim, cov khoom cua txias, thiab kev ua haujlwm.
Kev sib raug zoo ntawm Transformer suab nrov thiab Sib Nqus Hlau Sheet Hom thiab Core Sib Nqus Flux Density
Cov khoom sib nqus hlau sib txawv muaj cov yam ntxwv sib txawv magnetostriction.
Txawm hais tias CRGO steel siv, lub suab nrov ntawm lub tshuab hluav taws xob tuaj yeem sib txawv nyob ntawm qib steel, sib nqus flux ceev, grain orientation, core joint design, thiab mechanical stress.
Raws li kev sib nqus flux ceev nce, magnetostriction thiab electromagnetic vibration feem ntau tuaj yeem pom ntau dua.
Qhov ntawd yog ib qho laj thawj transformer designers zam tsuas yog thawb cov tub ntxhais mus rau qhov siab heev flux ceev. Kev tsim cov hlau nplaum ntau dua tuaj yeem txuag tau qee yam khoom, tab sis nws tuaj yeem ua rau cov tub ntxhais poob thiab suab nrov.
Qhov kawg tsim yuav tsum nrhiav kom tau qhov sib npaug.
Kev sib raug zoo ntawm Transformer suab nrov thiab Core Clamping Force
Core clamping quab yuamkuj muaj qhov pom tseeb ntawm lub suab nrov ntawm transformer.
Yog hais tias cov tub ntxhais tsis tau clamped nruj txaus, laminations yuav txav los yog co tawm tsam ib leeg. Qhov no tuaj yeem ua rau lub suab nrov nrov.
Tab sis ntau dhau clamping tsis tas yuav zoo dua. Kev ntxhov siab ntau dhau tuaj yeem qhia txog kev ntxhov siab rau hauv cov hlau nplaum, uas tuaj yeem ua rau poob qis thiab hloov tus cwj pwm magnetostriction.
Lub hom phiaj yog tswj thiab uniform clamping. Txaus kom cov tub ntxhais ruaj khov, tab sis tsis ntau npaum li cov khoom siv hlau nplaum tsis tsim nyog.
Vim li cas Transformer Core Quality Matters
Nws yog ib qho yooj yim los saib xyuas cov tub ntxhais vim hais tias cov windings feem ntau tau txais kev saib xyuas ntau dua thaum tib neeg tham txog kev tsim transformer.
Tab sis lub hauv paus tseem ceeb muaj feem cuam tshuam rau ntev - lub sij hawm transformer kev ua tau zoo.
Cov tub ntxhais tsim thiab tsim tau zoo tuaj yeem pab txo qistransformer tsis muaj -load poob, qis dua magnetizing tam sim no, txhim kho magnetic flux faib, txo kev co, tswj transformer suab nrov, thiab txhawb kev lag luam txhim khu kev qha.
| Core Design lossis Manufacturing Factor | Muaj peev xwm pab tau |
| High - zoo magnetic steel | Tsawg cov tub ntxhais kawm poob |
| Qhov tseeb lamination txiav | Txo cov neeg kho tshuab kev nyuaj siab |
| Tsim kom muaj kev sib koom ua ke | Zoo dua sib nqus flux faib |
| Zoo lamination rwb thaiv tsev | Tsawg circulating tam sim no |
| Tswj clamping quab yuam | Zoo dua mechanical stability |
| Qhov tseeb core grounding | Txo txoj kev pheej hmoo ntawm cov dej ntws |
| Optimized magnetic flux ceev | Sib npaug poob thiab suab nrov |
| Kev tsim khoom zoo ib yam | Xav paub ntau ntxiv txog kev ua haujlwm ntawm transformer |
Qhov tseem ceeb yog qhov tseem ceeb no ua haujlwm ua ke.
Daim ntawv siab - qib CRGO steel tsis tuaj yeem them nyiaj rau kev txiav tsis zoo. Lub qhov dej-tsim sib koom ua ke tsis tuaj yeem them nyiaj rau kev puas tsuaj lamination. Thiab cov tub ntxhais muaj zog mechanically tseem tuaj yeem ua haujlwm tsis zoo yog tias nws ua haujlwm ntawm qhov sib nqus flux ntom ntom tsis haum.
Lub transformer core yuav tsum tau kho raws li ib tug ua tiav system.

Covtransformer tub ntxhaisyog lub hauv paus sib nqus ntawm lub tshuab hloov pauv, thiab nws qhov zoo muaj qhov cuam tshuam ncaj qha rau kev ua haujlwm, kev ntseeg siab, suab nrov, thiab cov nqi khiav lag luam.
Cov txheej txheem pib nrog kev xaiv cov khoom tsim nyog, seb qhov ntawd txhais tau tias txias -rolled grain- taw qhia hluav taws xob hlau, amorphous alloy, lossis lwm yam khoom siv hlau nplaum tsim nyog. Los ntawm qhov ntawd, cov tub ntxhais geometry, lamination thickness, kev sib koom ua ke, kev txiav raug, stacking, clamping, rwb thaiv tsev, hauv av, thiab kev tswj xyuas txhua qhov tseem ceeb.
Rautransformer tsis muaj -load poob, kev tsim cov ntsiab lus tuaj yeem yog qhov tseem ceeb raws li cov khoom siv nws tus kheej. Mechanical stress, burrs, rwb thaiv tsev puas, cov pob qij txha tsis zoo, thiab tsis raug stacking tuaj yeem txo qhov kev ua tau zoo ntawm lwm yam siab - cov tub ntxhais zoo.
Tib yam siv rautransformer suab nrov. Sib nqus flux ceev, magnetostriction, cov khoom tseem ceeb, kev sib koom tsim, thiab clamping quab yuam cuam tshuam nrog ib leeg. Kev tswj lub suab nrov yog yog li kev sib txuam ntawm kev sib nqus tsim thiab kev tsim kho tshuab.
NtawmYog Transformer, transformer core tsim yog suav tias yog ib feem ntawm kev ua tiav transformer engineering txheej txheem. Los ntawm kev sib piv cov ntaub ntawv tseem ceeb, sib nqus tsim, kev tsim khoom, kev tsim kho tshuab, kev xav tau cua txias, thiab daim ntawv thov tiag tiag, lub tshuab hloov pauv tuaj yeem ua tiav qhov poob qis, tswj lub suab nrov, kev ua haujlwm ruaj khov, thiab lub neej ua haujlwm ntev.
