Fais fab Transformer Losses
Fais fab transformers yog cov khoom tseem ceeb hauv kev lag luam hluav taws xob hluav taws xob. Lawv yog lub luag haujlwm rau kev nce qib lossis nce qib voltage, ua kom muaj hluav taws xob xa mus rau ntau qhov deb. Txawm li cas los xij, lub zog transformers tau poob thaum lub sijhawm ua haujlwm vim muaj ntau yam laj thawj. Cov kev poob no tuaj yeem ua rau muaj kev cuam tshuam loj rau kev ua tau zoo thiab kev ntseeg siab ntawm lub tshuab hluav taws xob.
Kev poob hauv lub hwj chim transformers tuaj yeem muab faib ua ob hom loj: tooj liab poob thiab hlau poob. Kev poob tooj liab kuj tseem hu ua ohmic poob thiab tshwm sim vim qhov tsis kam ntawm transformer windings. Cov kev poob no yog ncaj qha proportional rau lub square ntawm transformer tam sim no thiab yuav txo tau los ntawm kev nce tus ntoo khaub lig-section ntawm conductors siv. Hlau poob, ntawm qhov tod tes, yog vim magnetization thiab demagnetization ntawm transformer core. Cov kev poob no tseem hu ua hysteresis thiab eddy tam sim no poob thiab tuaj yeem txo los ntawm kev siv cov ntaub ntawv zoo thiab laminations.
Tag nrho cov kev poob hauv lub hwj chim transformer tuaj yeem txiav txim siab los ntawm kev ua qhov tsis muaj kev thauj khoom thiab kev kuaj xyuas. Thaum lub sij hawm ib tug tsis muaj-load xeem, lub transformer yog disconnected los ntawm cov hluav taws xob system thiab yog muab nrog rated voltage ntawm rated zaus. Kev ntsuas qhov poob thaum qhov kev sim no suav nrog cov hlau poob thiab qhov me me ntawm cov tub ntxhais poob vim yog cov hlau nplaum tam sim no. Kev kuaj load yog ua nyob rau hauv ob qho xwm txheej: ib nrab load thiab puv load. Thaum lub sij hawm kuaj load, lub transformer yog txuas nrog cov hluav taws xob system thiab yog loaded nrog tam sim no uas tsim ib nrab thiab tag nrho-rated tso zis. Tom qab ntawd lub zog nkag mus rau lub transformer yog ntsuas, thiab cov tooj liab poob yog xam raws li qhov tsis kam ntawm windings.
Tag nrho efficiency ntawm lub hwj chim transformer yog cuam tshuam los ntawm qhov poob nws incurs. Raws li qhov poob nce, qhov ua tau zoo ntawm transformer txo. Qhov no tuaj yeem ua rau cov nqi hluav taws xob ntau dua thiab cov pa roj carbon ntau dua. Nyob rau hauv tas li ntawd, qhov poob ua kom sov nyob rau hauv lub transformer, ua rau ib tug nce nyob rau hauv kub. Qhov no tuaj yeem ua rau muaj kev puas tsuaj rau lub rwb thaiv tsev thiab txo lub neej ntawm lub transformer.
Hauv kev xaus, lub zog transformer poob yog ib qho tseem ceeb uas yuav tsum tau xav txog hauv kev tsim hluav taws xob thiab kev saib xyuas. Los ntawm kev nkag siab txog hom kev poob thiab lawv cov laj thawj, cov kev ntsuas tsim nyog yuav raug coj los ua kom cov transformer efficiency thiab kev ntseeg tau. Qhov no suav nrog kev xaiv cov khoom zoo, kev tsim kho kom zoo, thiab ua haujlwm tsis tu ncua los soj ntsuam qhov xwm txheej ntawm lub tshuab hloov pauv. Los ntawm kev ua li ntawd, nws muaj peev xwm ua kom ntseeg tau tias lub zog hloov hluav taws xob txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev lag luam hluav taws xob.
