Teb ceev: CT vs CVT Qhov txawv
Qhov sib txawv tseem ceeb ntawm CT thiab CVT yog qhov lawv ntsuas:
CT (Tam sim no Transformer)ntsuas hluav taws xobtam sim nothiab converts high tam sim no mus rau ib tug standardized low tam sim no (1A los yog 5A).
CVT (Capacitive Voltage Transformer)ntsuas siabhluav taws xobthiab converts nws mus rau hauv ib tug standardized low voltage (100V lossis 110V).
Hauv cov ntsiab lus yooj yim:CT ntsuas tam sim no. CVT ntsuas qhov voltage.
CT yog dab tsi? (Tam sim no Transformer)
A CTsawv rauTam sim no Transformer. Nws yog ib qho cuab yeej uas ntsuas cov hluav taws xob loj loj los ntawm kev nce mus rau qhov me me, tus nqi tsim nyog. Xav txog nws zoo li "tam sim no shrinker"- nws yuav siv cov tam sim no loj heev uas ntws los ntawm txoj kab hluav taws xob thiab hloov nws mus rau hauv qhov chaw nyab xeeb, tswj tau qhov teeb meem uasmetersthiabtiv thaiv relaystau nyeem.
Nws ua haujlwm li cas
Lub CT ua haujlwm ntawm lub hauv paus ntsiab lus ntawm electromagnetic induction-ib yam li lub tshuab hloov pauv tsis tu ncua. Nws muaj thawj winding nrog ob peb lem (tej zaum tsuas yog ib tug ncaj bar) thiab ib tug thib ob winding nrog ntau lem raug mob nyob ib ncig ntawm ib tug kaw hlau core.
Thaum cov tam sim no loj ntws los ntawm lub hauv paus, nws tsim ib magnetic teb nyob rau hauv cov tub ntxhais, uas induces ib proportional me me tam sim no nyob rau hauv lub thib ob winding. CovSecondary tam sim no yog ncaj qha proportional rau thawj tam sim noraws li CT ratio.
Cov qauv tseem ceeb:
CT Ratio=Thawj Tam Sim No / Secondary Tam Sim No
Piv txwv:
1000/5 CT TSItxhais tau tias:
Qhov tseem ceeb tam sim no:1000A

CVT yog dab tsi? (Capacitive Voltage Transformer)
A CVTsawv rauCapacitive Voltage Transformer Cov. Nws yog ib qho cuab yeej uas ntsuas cov hluav taws xob siab los ntawm kev nce mus rau qhov muaj kev nyab xeeb, tus qauv qis qis. Nws yog dav siv nyob rau hauvsiab -voltage kis systems, tshwj xeeb hauv110kV, 220kV, thiab 500kV substations.
Nws ua haujlwm li cas
Tsis zoo li CT (lossis ib txwm siv hluav taws xob PT), CVT tsis tso siab rau electromagnetic induction. Hloov chaw, nws siv acapacitive voltage dividerua raws li ib tug me me electromagnetic transformer.
Cov txheej txheem yooj yim:
Ib tug series ntawm capacitors faib lub siab input voltage (piv txwv li, 110 kV) mus rau ib tug nruab nrab voltage.
Lub tshuab hluav taws xob electromagnetic ces nqis mus ntxiv mus rau tus qauv qis voltage (100V lossis 110V).
Cov ntawv thov siv
Voltage ntsuas rau metering thiab tswj
Relay tiv thaiv (kev taw qhia overcurrent, kev tiv thaiv nyob deb)
Fais Fab Kab Kev Sib Txuas Lus (PLCC)-ib qho kev ua haujlwm ntxiv uas CVTs ob peb lub siab - zaus sib txuas lus xa mus rau cov kab xa mus rau telemetry thiab kev tiv thaiv tej thaj chaw deb teeb liab.

Cov lus nug nquag nug (FAQ)
Q1: CT thiab CVT puas tuaj yeem siv ua ke?
Yog lawm. CTs thiab CVTs feem ntau tau teeb tsa ua ke hauv substations. CTs ntsuas tam sim no thaum CVTs ntsuas qhov hluav taws xob. Ob lub teeb liab raug pub rau hauv kev tiv thaiv relays thiab ntsuas ntsuas hluav taws xob (kW) thiab impedance.
Q2: Qhov txawv ntawm CT thiab PT yog dab tsi?
CT ntsuas tam sim no. PT (Potential Transformer) ntsuas qhov hluav taws xob. Ib txwm PTs siv electromagnetic induction, thaumCVT(ib hom subtype ntawm PT) siv cov kev faib hluav taws xob muaj peev xwm-tshwj xeeb yog tsim los rau ntxiv- siab- cov ntawv siv hluav taws xob uas ib txwm siv PTs hnyav dhau thiab kim.
Q3: Vim li cas CVTs siv hloov PTs rau qhov hluav taws xob siab?
CVTs ntau duakev lag luam thiab siv taurau cov ntawv thov ntxiv -siab-voltage (EHV). Lawv sib zog, muaj kev ua tau zoo ntawm rwb thaiv tsev, thiab muab kev ua haujlwm ntxiv ntawm cov cab kuj sib txuas, uas cov PTs ib txwm tsis tuaj yeem muab tau.
Q4: Yuav ua li cas yog tias CT thib ob qhib?
Ib qho qhib CT theem nrab tuaj yeem tsim tautxaus ntshai heev voltage(txog li ob peb kilovolts) vim yog core saturation. Qhov no ua rau muaj kev nyab xeeb txaus ntshai rau cov neeg ua haujlwm thiab tuaj yeem ua rau cov rwb thaiv tsev puas.Tsis txhob qhib CT thib ob Circuit Court thaum lub hauv paus tseem muaj zog.
