Hauv peb lub chaw kuaj sim ntawm Wuxi Huipu Electronics Co., Ltd., kev ua haujlwm tsis yog ib tus lej ntawm cov ntaub ntawv xwb- nws yog qhov ua kom lub zog hluav taws xob ua haujlwm txias tom qab 10,000 teev ua haujlwm tas li. Tau ntau xyoo, peb tau kawm tias kev ua haujlwm ntawm transformer tsis yog txiav txim los ntawm ib qho "magic" spec. Nws yog qhov tshwm sim ntawm kev ntsuas peb qhov sib cuam tshuam: kev poob, cua txias, thiab yuav ua li cas lub transformer ua tau raws li qhov tseeb load.
Nkag siab txog qhov poob qhov teeb meem
Xyoo tas los, tus neeg siv khoom tsim kev lag luam UPS tau thov kom peb pab txhim kho kev hloov pauv ntawm 94% mus rau 97%. Nyob rau hauv daim ntawv, tus qauv tsim tau zoo li cov khoom zoo: cov tub ntxhais kawm qib zoo, kev ntsuas hlau txaus, qhov sib npaug ntawm qhov tseeb. Tab sis nyob rau hauv tag nrho cov load ntawm 50Hz, lub tsev khiav kub tshaj qhov xav tau, thiab efficiency poob.
Peb taug qab qhov teeb meem mus rau peb qhov chaw poob ua haujlwm ua ke:
- Cov tub ntxhais poob: Txawm tias muaj cov qib zoo silicon steel, hysteresis thiab eddy tam sim no poob nce nonlinearly nrog flux ceev. Los ntawm kev ua kom zoo tshaj qhov tseem ceeb stacking thiab kho qhov chaw khiav hauj lwm flux, peb txo tsis muaj -load poob los ntawm 12%.
- Copper poob: DC tsis kam yog nyob rau hauv spec, tab sis AC tsis kam ntawm kev khiav hauj lwm zaus yog siab dua vim hais tias qhov sib thooj nyhuv nyob rau hauv nruj packed windings. Hloov mus rau qhov hloov pauv winding qauv txiav AC poob los ntawm 18%.
- Kev poob qis: Cov dej ntws tawm tau ua rau cov dej ntws ntws tawm hauv qhov txuas txuas. Ntxiv ib qho yooj yim uas tsis yog -magnetic spacer tshem tawm qhov kev poob zais.
Qhov tshwm sim: 97.2% efficiency ntawm tag nrho cov load, nrog 15℃txo qhov kub ntawm hotspot.
Txias: Qhov Ua Tau Ua Tau Zoo Tshaj Plaws
Thaum tshav kub kub tsis yog qhia tias poob - nws ua rau nws nrawm dua. Copper kuj nce txog 0.4% ib degree; core permeability yuav drift nrog kub. Peb tau ntsuas qhov kev ua tau zoo ntawm 2-3% ntawm 25℃thiab 75℃cov ntsiab lus ua haujlwm hauv cov qauv tsim tsis zoo.
Ntawm Huipu Electronics, tam sim no peb kho thermal tswj raws li ib feem ntawm cov txheej txheem tsim hluav taws xob. Cov tswv yim txhim kho uas xa cov txiaj ntsig tiag:
- Xaiv cov khoom bobbin nrog thermal conductivity zoo dua
- Optimizing winding layout los tsim cov huab cua ntws raws
- Ntxiv cov khoom siv thermal interface ntawm cov tub ntxhais thiab chassis rau siab -cov qauv tsim
Ib txoj haujlwm tsis ntev los no rau lub xov tooj hluav taws xob hluav taws xob pom kev ua haujlwm tau zoo dua los ntawm 1.8% tsuas yog los ntawm kev hloov pauv hloov pauv kom haum rau qhov chaw nyob ntawm txoj kev airflow -tsis muaj qhov hloov pauv yuav tsum tau ua.
Load Conditions: Vim li cas "Nameplate Efficiency" tuaj yeem yuam kev
Transformers tsis tshua muaj kev khiav hauj lwm raws nraim 100% load. Qhov tseeb, ntau tus siv feem ntau ntawm lawv lub sijhawm ntawm 30-70% load. Yog vim li cas qhov kev ua tau zoo nkhaus tseem ceeb dua li ib qho - taw tes ntsuas.
Peb tsis ntev los no tau pab tus neeg siv khoom uas nws lub tshuab hloov pauv tau ntsib 96% kev ua haujlwm ntawm kev thauj khoom tag nrho tab sis poob mus rau 89% ntawm lub teeb thauj khoom - teeb meem rau lub cuab yeej siv 80% ntawm nws lub sijhawm nyob rau hauv standby. Qhov teeb meem yog ntau tshaj magnetizing tam sim no vim yog ib qho tseem ceeb. Los ntawm txoj cai- qhov loj me thiab kev ua kom zoo ntawm qhov sib txawv ntawm huab cua, peb flattened lub efficiency nkhaus: 94% ntawm 25% load, 96.5% ntawm 50-100% load.
Kev pom tseem ceeb: kev ua haujlwm zoo tshaj plaws tsis yog hais txog kev ua kom tau zoo tshaj plaws ntawm ib qho. Nws yog hais txog kev sib piv cov transformer qhov poob profile rau koj qhov tseeb load faib.
Peb cov txheej txheem ua kom zoo tshaj plaws
Thaum cov neeg thov kom peb txhim kho kev ua haujlwm ntawm transformer, peb tsis pib nrog kev xav. Peb thov:
- Qhov tseeb ua haujlwm waveforms thiab thauj cov profiles
- Cov duab tshav kub lossis ntsuas kub los ntawm thaj chaw
- Cov ntaub ntawv ua tau zoo thoob plaws kab / thauj khoom / qhov kub thiab txias
Tom qab ntawd peb:
1. Sib tsoo qhov kev poob los ntawm kev simulation thiab ntsuas qhov ntsuas
2. Txheeb xyuas seb puas yog cov tub ntxhais, tooj liab, lossis kev poob qis hauv koj daim ntawv thov
3. Tus qauv tsom kev txhim kho nrog nrawm - tig rov ua dua
4. Siv tau raws li qhov tiag -kev ntxhov siab hauv ntiaj teb- tsis yog lub hom phiaj ntawm kev sim
Kab hauv qab
Fais fab transformer efficiency tsis optimized los ntawm chasing ib spec. Nws yuav tsum muaj kev ntsuas hluav taws xob tsim hluav taws xob, kev coj tus cwj pwm thermal, thiab tiag - qauv kev ua haujlwm hauv ntiaj teb. Yog tias koj daim ntawv thov xav tau kev ua haujlwm siab thoob plaws qhov sib txawv ntawm qhov sib txawv lossis qhov nyuaj thermal ib puag ncig, qhia koj cov kev xav tau tshwj xeeb nrog peb.
Ntawm Wuxi Huipu Electronics Co., Ltd., peb tsis muab cov kev daws teeb meem generic transformer. Peb txhim kho kev ua tau zoo raws li ntsuas cov ntaub ntawv poob, thermal validation, thiab teb - pov thawj kev ntseeg tau. Vim hais tias hauv hluav taws xob hluav taws xob, txhua qhov feem pua ntawm cov ntsiab lus tsis yog tus lej xwb - nws muaj cua sov tsawg dua, kev pab lub neej ntev dua, thiab cov khoom lag luam muaj kev vam khom rau koj cov neeg siv khoom kawg.
