qhov cuam tshuam ntawm qhov kub thiab txias rau kev sim siab

Qhov kev hloov pauv ntawm qhov kub thiab txias yuav cuam tshuam tag nrho rau qhov kev tiv thaiv rwb thaiv tsev, yog li thaum qhov kub thiab txias sab nraud txuas ntxiv nce, kev txav mus los ntawm cov molecules thiab ions hauv cov khoom siv rwb thaiv tsev yuav txuas ntxiv ua kom nrawm dua qhov kev txav mus los nrog qhov nce ntawm qhov kub thiab txias, uas yuav ua rau lub polarity ntawm kev tiv thaiv rwb thaiv tsev tuaj yeem txhim kho, thiab qhov kev tiv thaiv rwb thaiv tsev raug txo qis. Tib lub sijhawm, thaum lub sijhawm nce qhov kub thiab txias, qhov kev txav mus los ntawm cov dej molecules hauv qhov kev tiv thaiv rwb thaiv tsev yuav txuas ntxiv ua kom nrawm dua, yog li cov khoom tsis huv ntawm qhov chaw ntawm kev tiv thaiv rwb thaiv tsev tuaj yeem yaj sai, yog li qhov kev tiv thaiv tuaj yeem txo qis sai. Tsis tas li ntawd, qhov kev txo qis ntawm kev tiv thaiv rwb thaiv tsev yog ncaj qha cuam tshuam nrog cov av ntawm qhov chaw. Tib lub sijhawm, kev tshuaj xyuas ntawm qee cov ntaub ntawv tshawb fawb qhia tau hais tias qhov kev hloov pauv ntawm qhov kub thiab txias kuj tseem yuav ua rau qhov kev hloov pauv ntawm qhov piv ntawm kev nqus rwb thaiv tsev ntawm transformer. Hauv qhov no, nws tuaj yeem faib ua ob qho xwm txheej. Rau qhov qhuav hloov pauv siab Lu, qhov piv ntawm kev nqus yuav nce nrog qhov nce ntawm qhov kub thiab txias. Txawm li cas los xij, thaum qhov kub thiab txias nce mus txog ntau dua 40 ℃, qhov piv ntawm kev nqus yuav txo qis. Hauv lwm qhov xwm txheej, nrog rau qhov nce ntawm qhov kub thiab txias, qhov piv ntawm kev nqus yuav txo qis.

qhov cuam tshuam ntawm qhov ceev ntawm kev nce siab

Hauv qhov kev sim siab-voltage, qhov ceev ntawm kev txhawb nqa yuav cuam tshuam rau qhov xau tam sim no, yog li hauv qhov kev sim, nws yog qhov tsim nyog los tuav kom yooj yim raws li lub peev xwm ntawm lub transformer kom tswj tau qhov tshwm sim ntawm qhov yuam kev ntau li ntau tau, kom ntseeg tau qhov tseeb ntawm cov txiaj ntsig ntawm kev sim siab-voltage.

piv txwv ntawm kev sim hluav taws xob transformer

Piv txwv li, siv qhov kev sim DC tsis kam ntawm winding thiab bushing, cov teeb meem uas yuav tsum tau saib xyuas hauv qhov kev sim no tau piav qhia luv luv. Vim tias lub transformer winding muaj inductance loj thiab mutual inductance, tab sis muaj qhov tsis kam me me, raws li lub sijhawm tas mus li yog L / R, nws yuav pom tias lub sijhawm tas mus li loj heev. Hauv qhov no, yog tias tam sim no yuav ruaj khov, lub sijhawm them yuav ntev heev. Yog li ntawd, rau qee lub transformers loj, lub sijhawm sim yuav tsum luv li sai tau. Yog tias nws yog los ntsuas qhov tsis kam hauv lub winding qis-voltage ntawm lub transformer loj, vim tias muaj ob peb qhov tig zoo siab ntawm qhov kawg qis-voltage, txoj kev ntawm series winding magnetization tuaj yeem siv tau thiab hom kev sib txuas kom raug yuav tsum tau xaiv.
