Qhov Chaw Thawj: Lub Teeb ntawm Cov Khoom Siv
Hauv tsab xov xwm txog kev txo nqi ntawm cov transformers, peb tau tham txog kev hloov cov khoom siv, kev ua kom zoo dua qub, thiab lwm yam uas tuaj yeem ua rau muaj kev hloov pauv hauv kev ua haujlwm ntawm transformer.
Yog li ntawd, thaum lub sijhawm txo tus nqi, kev sim lwm txoj hauv kev tseem ceeb heev. Tsab xov xwm no yuav tham txog cov ntsiab lus tseem ceeb ntawm kev sim hloov pauv transformer los ntawm ob qho: cov chaw tsim khoom transformer thiab cov chaw tsim khoom siv hluav taws xob.
Yog xav hloov cov khoom siv, cov chaw tsim khoom transformer yuav tsum soj ntsuam nws qhov cuam tshuam rau transformer nws tus kheej. Yog tias lub hlau nplaum raug hloov, thawj qhov yuav tsum xav txog yog qhov kev hloov pauv ntawm nws qhov loj me uas yuav cuam tshuam rau transformer.
Txawm tias rau tib qho kev qhia tshwj xeeb thiab qauv, cov cuab yeej sib tsoo siv los ntawm txhua tus neeg tsim khoom siv hlau nplaum feem ntau txawv, ua rau muaj ntau qhov loj me; Qhov sib txawv ntawm cov txheej txheem sintering kuj tseem tuaj yeem ua rau muaj kev kam rau siab sib txawv ntawm cov hlau nplaum, ob qho tib si tuaj yeem ua rau muaj kev hloov pauv hauv kev sib phim ntawm cov hlau nplaum thiab pob txha. Yog tias muaj kev hloov pauv tseem ceeb uas ua rau tsis muaj peev xwm sib sau ua ke lossis qis kev sib dhos ua haujlwm, nws tsis tsim nyog poob.
Qhov thib ob, cov yam ntxwv tseem ceeb ntawm cov khoom siv hlau nplaum yuav tsum ze. Rau cov yam ntxwv tshwj xeeb xws li thawj qhov permeability magnetic (μi), saturation magnetic induction intensity (Bs), kev siv hluav taws xob (Pv), Curie kub (Tc), qhov ceev, tensile kev ua tau zoo, kev co kev ua tau zoo, thiab lwm yam, thov saib tsab xov xwm "Cov yam ntxwv ntawm Magnetic Cores". Muaj ib daim ntawv sib piv cov khoom siv hauv kev lag luam ua ib qho kev siv, thiab koj tuaj yeem nrhiav cov chaw tsim khoom hlau nplaum los muab nws.
Rau cov hlau, cov yam xws li cov xim pleev xim tuab, cov txheej rwb thaiv tsev tuab, qhov loj ntawm lub cheeb sab nraud, hluav taws xob tiv taus, qib kub tiv taus, thiab lub peev xwm rwb thaiv tsev yuav tsum tau xav txog. Rau cov hlau rwb thaiv tsev peb txheej, daim ntawv pov thawj ntawm lub kaw lus rwb thaiv tsev yuav tsum tau xav txog. Feem ntau, cov hlau rwb thaiv tsev sib txawv muaj cov txheej txheem rwb thaiv tsev sib txawv. Tshwj tsis yog tias tus neeg siv khoom tsis xav tau lub kaw lus rwb thaiv tsev, qhov ntawd yog lwm yam teeb meem.
Thaum hloov lub pob txha, yuav tsum xav txog cov yam xws li cov khoom siv, phab ntsa tuab, ntxig thiab tshem tawm PIN, thiab lub zog ntawm lub pob txha. Qhov tseem ceeb tshaj plaws yog qhov dav thiab qhov tob ntawm qhov, uas yuav tsum tau khaws cia kom sib xws, txwv tsis pub nws yuav ua rau muaj kev hloov pauv ntawm cov txheej winding thiab kev faib tawm tig, thiab kev ua tau zoo kuj yuav hloov pauv raws li.
Kev hloov pauv transformer, cov khoom sim niaj hnub rau kev muab hluav taws xob suav nrog qhov kub nce, kev ua haujlwm zoo, tus nqi PF, THD (tag nrho harmonic distortion), qhov nrawm hloov kho, ripple, EMC, thiab lwm yam, nrog rau kev sim kev ntxhov siab ntawm cov khoom tseem ceeb xws li thawj MOS thiab thib ob Schottky diode. Cov khoom sim kev ntseeg tau suav nrog kev pib kub siab thiab qis, kev laus kub siab thiab qis, thiab kev sim kev ntseeg tau ob npaug 85.
Kev ua haujlwm tsis siv neeg yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm cov transformers. Thaum tsim nyog, yuav tsum tau muab cov txheej txheem rhuav tshem kom ntseeg tau tias cov khoom sib xws thaum lub sijhawm tsim khoom tsis siv neeg thiab tshem tawm cov kev pheej hmoo zoo.
Hais txog kev hloov cov khoom siv thiab kev ua kom zoo dua qub, cov chaw tsim khoom siv hluav taws xob tsis yog tsuas yog yuav tsum ua kom tau raws li cov qauv yooj yim xwb, tab sis kuj yuav tsum ua kom tau raws li cov kev cai ntawm kev ntseeg tau. Yog xav paub ntxiv, thov saib tsab xov xwm dhau los "Kev ntseeg tau ntawm lub transformer suav nrog dab tsi."
Rau cov chaw tsim khoom siv fais fab, kev hloov cov khoom siv, kev ua kom zoo dua qub, thiab kev qhia cov neeg muag khoom tshiab yog cov kev hloov pauv tseem ceeb. Ntxiv nrog rau kev lees paub cov yam ntxwv yooj yim thiab kev ntseeg siab ntawm lub tshuab hloov pauv, nws tseem yog qhov tsim nyog los lees paub qhov ua tau zoo ntawm lub tshuab hloov pauv ntawm lub zog fais fab. Xyuas kom tseeb tias qhov hloov pauv yog qhov tsim nyog thiab txhim khu kev qha, thiab tuaj yeem ua tau raws li qhov xav tau ntawm tag nrho lub tshuab hauv ntau.
