PT thiab CT hauv Transformers: Cov Neeg Ua Siab Zoo Tsis Tau Txais Kev Pab ntawm Voltage thiab Current

PT thiab CT hauv Transformers: Cov Neeg Ua Siab Zoo Tsis Tau Txais Kev Pab ntawm Voltage thiab Current

Thaum nws los txog rau transformers,PT(Muaj peev xwm hloov pauv tau) thiabCT(Current Transformer) zoo li ob tug neeg ua haujlwm sib txawv ntawm lub ntiaj teb hluav taws xob - Batman thiab Robin. Lawv yuav tsis ua haujlwm zoo li lub transformer nws tus kheej, tab sis ob tug no ua haujlwm tom qab qhov xwm txheej kom ntseeg tau tias txhua yam khiav tau zoo thiab muaj kev nyab xeeb. Cia peb kawm txog lawv ua haujlwm li cas hauv kev teeb tsa transformer sib txawv.

PT: Tus Neeg Hais Lus Txog Qhov Voltage

LubLub Transformer Muaj Peev Xwm (PT)yog koj tus neeg uas koj xaiv los pab txo qhov hluav taws xob siab mus rau qib uas koj tswj tau. Xav txog seb koj tab tom cuam tshuam nrog qhov hluav taws xob loj heev 33 kV (lossis siab dua) hauv koj lub zog fais fab—qhov no txaus ntshai thiab yeej tsis yog ib yam dab tsi uas koj xav ntsuas ncaj qha. Qhov ntawd yog qhov uas PT los pab. Nws hloov cov hluav taws xob uas ua rau koj lub meters thiab relays ua haujlwm tau yam tsis tas yuav ua kom koj lub zog poob qis, feem ntau yog txo nws mus rau 110 V lossis 120 V.

Yog li, koj nrhiav tau PTs qhov twg hauv kev nqis tes ua?

• Cov transformers kis tau hluav taws xob siabCov no yog cov phom loj ntawm lub zog fais fab, tswj cov voltages txhua qhov chaw ntawm 110 kV txog 765 kV. Cov PTs ntawm no ua kom koj tuaj yeem saib xyuas thiab ntsuas voltage kom muaj kev nyab xeeb los ntawm deb.
• Cov hloov pauv hauv chaw nres tshebCov PTs ua haujlwm hauv cov chaw hloov hluav taws xob los saib xyuas thiab tswj cov theem hluav taws xob ua ntej nws faib rau cov neeg siv khoom hauv kev lag luam lossis cov neeg nyob hauv tsev.
• Kev tiv thaiv thiab kev ntsuas transformersHauv cov kab ke uas kev saib xyuas hluav taws xob tseem ceeb rau kev nyab xeeb thiab kev them nqi, PTs nqis tes los muab cov ntawv nyeem hluav taws xob raug rau cov chav tswj hwm, relays, thiab cov khoom siv tiv thaiv.

PT zoo li tus neeg txhais lus uas nyob twj ywm, sau ua ke ntawm kev hais kwv txhiaj hluav taws xob nrov nrov, coj cov ntawv suab 110 kV uas ua rau pob ntseg tawg thiab hloov lawv mus ua lub suab nrov mos mos uas koj cov khoom siv tuaj yeem ua tau.

CT: Tus Tam Sim No Tam Sim No

Tam sim no, cia peb tham txog qhovTam sim no Transformer (CT), tus kws qhia tus kheej ntawm lub zog fais fab. Thaum cov tam sim no pib ua rau nws cov leeg nqaij nrog ntau txhiab amps ntws los ntawm koj lub transformer, CT nqis tes los tswj nws kom qis mus rau qib nyab xeeb - feem ntau yog nyob rau hauv ntau ntawm 5 A lossis 1 A.

Koj yuav pom cov CT dai hauv:

• Kev Hloov Pauv Hloov ChawsCov txiv neej no ua haujlwm rau thaj chaw nyob lossis chaw ua lag luam, feem ntau khiav ntawm qhov hluav taws xob xws li 11 kV txog 33 kV. Cov CTs ntawm no ua kom muaj kev saib xyuas thiab kev tiv thaiv tam sim no, khaws cov ntaub ntawv ntawm seb cov kua txiv ntws ntau npaum li cas los ntawm cov kab.
• Cov Hloov Fais Fab hauv cov chaw hloov pauvCov CTs saib xyuas qhov tam sim no ntawm cov chaw hloov pauv hluav taws xob siab uas cov transformers txo qis qhov hluav taws xob los ntawm cov theem kis (piv txwv li, 132 kV lossis siab dua) mus rau cov theem faib khoom. Lawv tseem ceeb heev rau kev kuaj pom qhov tsis zoo thiab ua rau cov khoom siv tiv thaiv ua ntej muaj qee yam tsis raug.
• Cov tshuab hloov pauv kev lag luamHauv cov chaw tsim khoom lossis thaj chaw muaj kev lag luam hnyav, cov transformers feem ntau tuav cov khoom hnyav, thiab CTs nyob ntawd los saib xyuas cov dej ntws loj heev. Yog tias muaj qee yam tsis raug, CT xa cov ntaub ntawv mus rau cov kab ke tiv thaiv uas kaw cov khoom ua ntej cov khoom siv raug kib.

Xav txog CT ua tus neeg saib xyuas ntawm lub club - nws ua rau tam sim no nyob rau hauv kev kuaj xyuas kom nws tsis txhob overwhelm koj cov kab ke tiv thaiv, thiab yog tias tej yam tau dhau los ua rowdy, CT ua kom ntseeg tau tias ib tug neeg ntaus qhov chaw nres tsheb thaum muaj xwm txheej ceev.

Vim li cas PT thiab CT thiaj tseem ceeb

Ua ke, PT thiab CT tsim cov phooj ywg zoo tshaj plaws rau lub ntiaj teb transformer. Lawv yog qhov laj thawj uas cov neeg ua haujlwm tuaj yeem saib xyuas thiab tswj kev ua haujlwm ntawm transformer yam tsis tas yuav mus cuag tus tsiaj nyaum (ntseeg kuv, koj tsis xav mus ze rau hom voltage thiab tam sim no yam tsis muaj kev tiv thaiv loj). Txawm hais tias nws yog ib qholub tshuab hluav taws xob faib khoomhauv koj lub zej zog hauv zos lossis ib qholub tshuab hluav taws xob siabpub fais fab thoob plaws hauv nroog, PTs thiab CTs yeej ib txwm nyob ntawd, ua kom lub zog thiab tam sim no nyob hauv kab.

Qhov Tseeb Lom Zem: Khaws Qhov Muag Ntawm Ob Sab

Puas tau xav tsis thoob tias vim li cas koj daim nqi hluav taws xob thiaj raug heev? Koj tuaj yeem ua tsaug rau CTs thiab PTs hauvcov hloov pauv ntsuasLawv xyuas kom meej tias ob lub tuam txhab hluav taws xob thiab cov neeg siv khoom paub tseeb tias muaj pes tsawg lub zog siv los ntawm kev ntsuas qhov hluav taws xob thiab tam sim no kom raug. Yog li, yog, PT thiab CT ua kom tej yam ncaj ncees thiab sib npaug ntawm ob sab ntawm lub zog hluav taws xob.

Xaus lus

Yog li ntawd, txawm tias nws yog lub transformer kis tau zoo heev lossis lub transformer faib khoom siv zog ua haujlwm,PT thiab CTyog cov phab ej uas tsis muaj npe nrov uas ua kom txhua yam khiav tau zoo. Lawv tswj cov hluav taws xob siab thiab cov hluav taws xob loj heev kom cov neeg ua haujlwm, cov relays, thiab cov meters tuaj yeem tswj hwm lawv yam tsis muaj khaub ncaws superhero. Lub sijhawm tom ntej koj qhib lub qhov hloov teeb, nco ntsoov - muaj ib pab pawg neeg saib xyuas hluav taws xob ua kom paub tseeb tias tam sim no thiab hluav taws xob ua haujlwm zoo.
