Cov hloov hluav taws xob tam sim no hauv cov khoom hluav taws xob

Cov hloov pauv tam sim no lossis CTS yog qhov tseem ceeb ntawm qhov chaw loj yog ntsuas thiab ua tiav. Cov kev hloov pauv no txo ​​qis - voltage expents thiab saib xyuas qhov tseeb tam sim no los ntawm AC kis tau yooj yim, cia rau ntawm cov ammeters. CT ua txoj haujlwm no los ntawm kev tsim cov kev sib txuas tam sim no hauv kev txhaj tshuaj thib ob uas yog ib feem ntawm qhov tam sim no nyob rau hauv thawj winding.
Qhov tseeb, lub hom phiaj tseem ceeb ntawm kev hloov pauv tam sim no txawv ntawm cov qauv hluav taws xob hloov. Cov hloov pauv tam sim no tsuas muaj ib qho mus rau qee qhov kev sib tw ntawm ib lub tiaj tiaj, lossis ib qho chaw tsheb npav tau tso rau hauv lub qhov. Vim tias qhov kev npaj ua ke ntawm Circuit Court, nws tsis yog qhov tseem ceeb uas CT kuj yog hu ua ib lub transformer.
Piv nrog no ultra - cov winding thawj lub ntsej muag, qhov mob theem nrab ntawm CT muaj ntau lub qhov txhab ntawm cov lus laminated ntawm cov khoom sib nqus. Cov tub ntxhais tus laminated laminated muaj ib ntu loj - ntu, uas minimizes lub sib nqus flux ntom nti - The exact geometry depends on the amount of current that must be reduced when the wire tries to output a constant current…regardless of the connected load.
Thaum lub sijhawm ua haujlwm, qhov kev txhaj tshuaj thib ob xa tawm tam sim no mus rau Ammeter) yog txaus - tshwj tsis yog lub volfage orove Piv nrog lub voltage transformer, qhov pib tam sim no ntawm tus hloov pauv tam sim no tsis yog nyob ntawm lub load theem nrab tam sim no ... Nws yog tswj hwm los ntawm sab nraud thauj.
Tus asuxiliary tam sim no feem ntau yog ntsuas nrog tus qauv 1 A lossis 5 A kom tau txais qhov kev ntsuas siab dua. Cov hloov pauv tam sim no tuaj yeem txo cov qib tam sim no los ntawm ntau txhiab tus mob amperes lossis nqis rau tus qauv ntawm cov ntawv thov ib txwm muaj ... rau kev siv ib txwm, qis rau 5 ib lossis 1 ib zaug ntxiv. Cov hloov pauv tam sim no tuaj yeem pab cov khoom siv thiab cov khoom siv hluav taws xob siab thiab muaj peev xwm tswj tau zoo los ntawm cov cab ze uas tau nqa siab ntev nqa lub zog siab - voltage zog.
Cov ntawv thov metering thiab lwm yam kev siv ntawm kev hloov pauv tam sim no. Piv txwv li, hloov pauv tam sim no ua haujlwm hauv lub hwj chim meters me, watt meters, watt - teev meters, thiab kev tiv thaiv repays. Cov hloov pauv tam sim no tseem tuaj yeem siv ua kev ncig xyuas coils hauv cov sib nqus Circuit Court sib xyaws lossis MCBS.
Piv nrog lub voltage transformer, tus voltage kais tuaj yeem yooj yim thiab muaj kev sib txuas nrog rau cov hluav taws xob ntsuas qhov hluav taws xob uas twb muaj hluav taws xob. Nyob rau hauv ib qho kev txhim kho ntau dua, tus hloov hluav taws xob voltage kuj tseem siv raws li kev tswj hwm kauj, los ntawm cov engineers twg tuaj yeem tswj hwm tus voltage. Cov taps voltage kho qhov voltage los tswj cov nqi thib ob ntawm ib qho nominal tus nqi.
Ntau dua tshwj xeeb, coj mus rhaub Txuas kev hloov kho tuaj yeem hloov kho cov zis hluav taws xob ntawm tus hloov pauv kom ntseeg tau tias tag nrho cov hluav taws xob tawm. Thaum cov kab voltage yog qis dua los yog siab dua li cov ntsuas hluav taws xob ntawm thawj lub tshuab hloov pauv ntawm cov hluav taws xob thib ob uas yuav ua rau cov khoom siv tam sim no thiab cov hluav taws xob tam sim no kom tsis muaj tseeb. Siv tus kais voltage tuaj yeem hloov lub voltage piv ntawm tus hloov pauv kom nws cov kev ntsuas hluav taws xob theem siab ntawm nws lub hom phiaj voltage. Ntawm cov hloov loj loj, tus kais ntawm cov nyiaj them ua ntej rau cov kev tawm tswv yim uas yog siab dua lossis qis dua li ib txwm. Hom voltage voltage sib txuas yog ib txwm teeb los ntawm cov khoom siv tivthaiv los teeb tsa cov kab hluav taws xob voltage tseem ceeb. Nyob rau hauv cov ntaub ntawv ntawm lub chaw tshwj xeeb lossis lub vev xaib voltage, tus xa khoom tuaj yeem hloov tus kais hluav taws xob kom haum ua ntej xa.
Lub voltage Coj mus rhaub yog txuas ncaj qha rau lub transformer winding. Cov naj npawb ntawm cov lem tau yuav tsum tau ntawm lub voltage kais ua, txwv tsis pub nws yuav nyob ntawm sab tsis ncaj ncees ntawm tus hloov.
Qhov chaw ntsuas hluav taws xob hloov hluav taws xob feem ntau suav nrog hauv kev teeb tsa kom tso cai ua uas xav tau lub transformer kom raug kaw. Lub tshuab tus neeg teb xov tooj yuav tsum tau txiav tawm ntawm lub hloov pauv thiab xa tawm qhov chaw nyab xeeb rau ntawm kev hloov chaw. Tom qab ntawd nws yuav tsum txav tus kais hloov los ntawm txoj haujlwm tam sim no mus rau txoj haujlwm tsim nyog.
