Kev faib tawm ntawm cov khoom me me tam sim no transformers rau kev tiv thaiv

Tej yam me me tam sim no hloov pauv rau kev tiv thaiv tuaj yeem faib ua ntau hom. Nyob rau tam sim no, lawv feem ntau muaj peb hom, xws li tiv thaiv kev tiv thaiv tam sim no transformer, txawv kev tiv thaiv tam sim no transformer thiab grounding kev tiv thaiv tam sim no transformer (xoom sib lawv liag tam sim no transformer). Nyob rau hauv ib txwm muaj xwm txheej, kev tiv thaiv tej yam me me tam sim no transformer feem ntau yog sib phim nrog cov relay. Thaum lub sijhawm luv Circuit Court overload thiab lwm qhov yuam kev ntawm txoj kab, nws muab lub teeb liab rau cov khoom xa hluav taws xob kom txiav tawm qhov txhaum Circuit Court, tiv thaiv kev nyab xeeb ntawm lub zog hluav taws xob.

Yog li, dab tsi yog cov haujlwm ua haujlwm thiab kev xav tau siv ntawm kev tiv thaiv me me tam sim no transformer? Hauv kev siv tswv yim, kev tiv thaiv hloov pauv tsuas pib ua haujlwm tau zoo thaum lub sijhawm tam sim no yog ntau kaum zaus ntawm qhov loj dua li qhov tam sim no. Yog li ntawd, ib qho ntawm qhov tseem ceeb rau nws yog kev ntseeg tau kev ua tau zoo thiab kev rwb thaiv tsev, thiab lwm qhov yog kom muaj qhov loj txaus qhov muaj peev txheej qhov tsis txaus thiab muaj peev xwm txaus thermal thiab dynamic kev ruaj ntseg.

Feem ntau, nyob rau ntawm cov rated load lub xeev, kev tiv thaiv tej yam me me tam sim no hloov pauv tuaj yeem ua tau raws li theem pib ntawm qhov tseeb qib yog qhov siab tshaj plaws thawj qhov tam sim no, uas yog, qhov tseeb uas tsis pub dhau qhov tseem ceeb. Tus lej tsis raug raws siab yog qhov sib piv ntawm qhov ntsuas cov kub qes tshaj qhov tseem ceeb rau lub ntsuas cov lej tam sim no. Thaum cov thawj coj tam sim no loj txaus, cov tub ntxhais hlau yuav saturate thiab tsis ua raws li cov thawj coj tam sim no, thiab qhov txwv tsis pub cov coefficient sawv cev rau tus yam ntxwv no.

Ib qho ntxiv, rau qhov sib txawv ntawm cov ntawv thov, nws tseem yog qhov yuav tsum tau txiav txim siab qhov tseeb ntawm qib me me tam sim no transformer siv. Qeb qhov tseeb ntawm kev tiv thaiv hloov pauv yog 5P thiab 10P, uas txhais tau tias kev tso cai yuam kev tam sim no yog 1% thiab 3% thaum thawj qhov tam sim no tau ntsuas kom raug. Tus nqi ua ke yuam kev yog 5% thiab 10% feem. Qhov tsis sib haum tam sim no thaum cov kab tsis ua kom muaj cua sov thiab Electromagnetic quab yuam, qhov hloov hluav taws xob tam sim no rau kev tiv thaiv yuav tsum tiv taus.

Tshawb xyuas qhov tseeb kev ua haujlwm. Thaum siv qhov ntsuas me me tam sim no hloov pauv, thaum lub tshuab hluav taws xob theem ob yog luv luv, ua kom cov txiaj ntsig ntawm cov thawj tam sim no uas tam sim no cov hloov hluav taws xob tuaj yeem tiv taus nyob hauv ib ob yam tsis muaj kev puas tsuaj hu ua rated luv luv thermal tam sim no. Thaum cov theem ob txoj hlua hluav taws xob luv luv, lub siab tus nqi ntawm cov hluav taws xob tam sim no uas hloov hluav taws xob tam sim no tuaj yeem tiv taus yam tsis muaj kev puas tsuaj yog hu ua rated dynamic ruaj khov tam sim no.
