Ua ntej tshaj plaws, peb yuav tsum tshawb xyuas qhov hluav taws xob hluav taws xob ntawm qhov chaw siv hluav taws xob, lub zog tiag tiag ntawm cov neeg siv thiab cov xwm txheej ntawm qhov chaw nws nyob, thiab tom qab ntawd xaiv ib qho los ntawm ib qho raws li cov ntaub ntawv qhia. nyob rau hauv lub transformer nameplate. Feem ntau, lub peev xwm, qhov hluav taws xob, tam sim no thiab ib puag ncig ntawm lub transformer yuav tsum raug txiav txim siab. Ntawm lawv, kev xaiv lub peev xwm Lub peev xwm yuav tsum tau txiav txim siab raws li lub peev xwm, qhov xwm txheej thiab kev siv lub sijhawm ntawm tus neeg siv khoom siv hluav taws xob, thiaj li xaiv lub peev xwm ntawm lub tshuab hluav taws xob.
Thaum lub sijhawm ua haujlwm ib txwm muaj, qhov hluav taws xob thauj khoom ntawm lub tshuab hluav taws xob yuav tsum dais yog li 75 txog 90% ntawm lub peev xwm ntsuas ntawm lub transformer. Thaum qhov tseeb load ntawm lub transformer yog ntsuas kom tsawg tshaj li 50% thaum lub sij hawm ua hauj lwm, lub me-capacity transformer yuav tsum tau hloov. Yog hais tias lub load yog ntau tshaj li qhov muaj peev xwm ntawm lub transformer, lub peev xwm loj transformer yuav tsum tau hloov tam sim ntawd.
Tib lub sijhawm, thaum xaiv atransformer, txiav txim siab tus nqi voltage ntawm thawj kauj ntawm lub transformer raws li cov kab fais fab mov, thiab xaiv qhov voltage tus nqi ntawm cov kauj kauj ruam thib ob raws li cov khoom siv hluav taws xob. Nws yog qhov zoo tshaj plaws los xaiv qhov tsawg-voltage peb-theem plaub-hlau fais fab mov. Qhov no tuaj yeem muab ob lub zog thiab teeb pom kev zoo tib lub sijhawm.
Thaum xaiv qhov tam sim no, kev saib xyuas yuav tsum tau them rau seb qhov kev thauj khoom tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm lub cev muaj zog thaum nws pib (vim tias qhov pib tam sim no ntawm lub cev muaj zog yog 4 txog 7 npaug ntau dua li ntawm kev ua haujlwm sinking).
Vim li cas transformers tsis tuaj yeem overloaded?
Kev ua haujlwm dhau los txhais tau hais tias tus nqi tam sim no tau teev tseg ntawm daim ntawv teev npe yog tshaj thaum lub tshuab hloov pauv tau ua haujlwm.
Nyob rau hauv cov xwm txheej tshwj xeeb, kev ua haujlwm dhau ntawm lub tshuab hloov pauv hauv lub sijhawm luv luv tsis tuaj yeem tshaj 30% ntawm cov ntsuas ntsuas (lub caij ntuj no), thiab nws yuav tsum tsis pub tshaj 15% hauv lub caij ntuj sov.
