Lub hwj chim npaum li cas tuaj yeem muaj peb-theem hluav taws xob ntsuas hluav taws xob tiv taus thiab yuav xaiv lub Transformer ntau npaum li cas
Lub zog hluav taws xob ntau npaum li cas tuaj yeem ntsuas peb-theem hluav taws xob tiv taus thiab yuav ua li cas xaiv lub tshuab hluav taws xob ntau
Lub hwj chim ntawm peb-theem 'meter' yog tsuas yog txiav txim los ntawm qhov tam sim no specification ntawm peb-theem meter thiab qhov hluav taws xob ntawm qhov chaw. Yog tias nws yog DC 'meter', lub hwj chim P=I tam sim no * U voltage * 3. Cia peb saib seb lub zog hluav taws xob peb-theem tuaj yeem tiv taus thiab yuav ua li cas xaiv lub transformer ntau yam.
1. Lub meter peb-theem tuaj yeem tiv taus ntau npaum li cas?
Yog hais tias qhov tam sim no specification ntawm peb-theem meter yog 40A thiab lub teb voltage yog 380V, ces lub hwj chim P=40A * 380V *3=45600W. Yog vim li cas muab faib los ntawm ib tug 3, vim hais tias qhov no yog ib tug peb-theem 'meter', 40A * 380V tsuas yog lub hwj chim ntawm ib theem kab, yog li ntawd peb-theem fais fab tuag yuav tsum muab multiplied los ntawm 3. Peb-theem direct-hom hluav taws xob meter yuav ncav cuag. mus txog 100A, yog li lub zog siab tshaj plaws ntawm lub ntsuas hluav taws xob ncaj qha tuaj yeem tiv taus 114, 000W ntawm lub zog. Yog hais tias lub hwj chim siab dua qhov no, qhov ncaj-hom peb-theem meter tsis tuaj yeem ua tau raws li qhov xav tau, peb yuav tsum siv cov ntsuas kev sib nrig sib inductance.
2. Yuav ua li cas xaiv lub transformer ntau yam
Kev sib nrig sib inductance meter tsis txwv lub hwj chim, tsuav yog qhov ntau ntawm qhov sib nrig sib inductor mus txog, txhua lub zog tuaj yeem siv tau. Piv txwv li, yuav ua li cas yog tias peb xav ntsuas lub hwj chim ntawm 20, 000 W, qhov tam sim no specification ntawm transformer hom yog 1.5 (6) A. Peb tuaj yeem xam qhov tam sim no ua ntej, I=P/U=20000W/380V=53A, tom qab ntawd peb siv lub tshuab hloov pauv hloov tam sim no mus rau qhov tam sim no nyob rau hauv qhov ntsuas ntawm qhov ntsuas. . Tam sim no ntau yam ntawm kev sib nrig sib inductance meter feem ntau yog 1.5 txog 6A. Yog tias tam sim no hloov mus rau 5A, 10 npaug ntawm lub tshuab hloov pauv yuav raug siv, yog li txhawm rau ntsuas lub zog ntawm 20, 000, tsuas yog 10 npaug ntawm lub tshuab hloov pauv yuav raug siv.
