PT thiab CT hauv Transformers: Unsung Heroes ntawm Voltage thiab Tam sim no

Thaum nws los txog rau transformers,PT(Potential Transformer) thiabCT(Tam sim no Transformer) zoo li lub zog duo ntawm lub ntiaj teb hluav taws xob-Batman thiab Robin. Lawv yuav tsis hog lub tsom teeb zoo li lub transformer nws tus kheej, tab sis ob qho no ua hauj lwm tom qab scenes los xyuas kom meej txhua yam khiav zoo thiab zoo. Cia peb dhia mus rau hauv yuav ua li cas lawv ua haujlwm lawv cov khawv koob hauv kev sib txawv transformer teeb.

PT: Qhov Voltage Whisperer

CovMuaj peev xwm Transformer (PT)yog koj mus-rau tus txiv leej tub rau kev nce qib high voltage mus rau theem tswj tau. Xav txog tias koj tab tom cuam tshuam nrog 33 kV monstrous (lossis siab dua) hauv koj lub zog hluav taws xob - txaus ntshai thiab tsis yog ib yam uas koj xav ntsuas ncaj qha. Qhov ntawd yog qhov uas PT tuaj rau hauv. Nws hloov cov plaub hau-tso qhov hluav taws xob mus rau hauv ib yam dab tsi koj cov meters thiab cov relays tuaj yeem ua haujlwm yam tsis muaj hws, feem ntau nws nqis mus rau qee yam xws li 110 V lossis 120 V.

Yog li, koj pom PTs nyob qhov twg?

• High-voltage kis tau tus mob transformers: Cov no yog cov phom loj ntawm daim phiaj hluav taws xob, tuav cov hluav taws xob nyob qhov twg los ntawm 110 kV txog 765 kV. PTs ntawm no kom paub tseeb tias koj tuaj yeem saib xyuas thiab ntsuas qhov ntsuas hluav taws xob zoo nyob deb.
• Substation transformers: PTs ua haujlwm hauv substations los saib xyuas thiab tswj cov qib voltage ua ntej nws muab faib rau cov neeg siv khoom lag luam lossis thaj chaw.
• Kev tiv thaiv thiab metering transformers: Hauv cov kab ke uas qhov ntsuas hluav taws xob yog qhov tseem ceeb rau kev nyab xeeb thiab kev them nqi, PTs nqis los muab cov kev nyeem hluav taws xob muaj tseeb rau chav tswj, relays, thiab cov cuab yeej tiv thaiv.

PT zoo li tus neeg txhais lus nyob twj ywm, sau rau ntawm lub suab nrov hluav taws xob, coj cov pob ntseg sib cais 110 kV sau ntawv thiab tig lawv mus rau hauv lub suab nrov uas koj cov cuab yeej siv tau.

CT: Tamer Tamer

Tam sim no, cia peb tham txog lubTam sim no Transformer (CT), lub hwj chim system tus kws qhia tus kheej. Thaum tam sim no pib flexing nws cov leeg nrog ntau txhiab lub amps ntws los ntawm koj lub tshuab hloov pauv, CT cov kauj ruam hauv kev tswj nws mus rau qib kev nyab xeeb - feem ntau nyob rau hauv thaj tsam ntawm 5 A lossis 1 A.

Koj yuav pom CTs dai tawm hauv:

• Fais fab transformers: Cov txiv neej no ua haujlwm rau thaj chaw nyob lossis chaw lag luam, feem ntau khiav ntawm qhov hluav taws xob xws li 11 kV txog 33 kV. CTs ntawm no ua kom muaj kev saib xyuas tam sim no thiab kev tiv thaiv, khaws tabs ntawm cov kua txiv hmab txiv ntoo ntau npaum li cas los ntawm cov kab.
• Fais fab transformers hauv substations: CTs saib xyuas qhov tam sim no ntawm high voltage substations qhov twg transformers nqis voltage los ntawm theem kis tau tus mob (xws li, 132 kV los yog siab dua) mus rau theem tis. Lawv yog qhov tseem ceeb rau kev kuaj xyuas qhov tsis raug thiab ua rau cov khoom siv tiv thaiv ua ntej muaj qee yam tsis raug.
• Industrial transformers: Hauv cov chaw tsim khoom lossis thaj chaw muaj kev lag luam hnyav, cov khoom siv hluav taws xob feem ntau tswj cov khoom hnyav, thiab CTs nyob ntawd los saib xyuas cov dej ntws loj. Yog tias muaj qee yam tsis raug, CT relays cov ntaub ntawv rau kev tiv thaiv cov khoom uas kaw ua ntej cov khoom yuav kib.

Xav txog CT ua tus bouncer ntawm ib lub club - nws khaws cov ntaub ntawv tam sim no kom tsis txhob cuam tshuam koj cov txheej txheem tiv thaiv, thiab yog tias muaj ntau yam tsis txaus ntseeg, CT ua kom ib tug neeg tsoo qhov xwm txheej ceev.

Vim li cas PT thiab CT teeb meem

Ua ke, PT thiab CT tsim qhov kawg buddy cop duo rau lub ntiaj teb transformer. Lawv yog vim li cas cov tswv lag luam tuaj yeem saib xyuas thiab tswj hwm kev ua haujlwm ntawm lub tshuab hluav taws xob yam tsis tas yuav mus rau lub cev mus rau cov tsiaj nyaum (tso ntseeg kuv, koj tsis xav kom ze li qhov voltage thiab tam sim no yam tsis muaj kev tiv thaiv loj). Seb nws yog ibfaib transformernyob rau hauv koj lub zos zej zog los yog ibhigh-voltage fais fab mov transformerpub fais fab thoob plaws tag nrho lub nroog, PTs thiab CTs yeej ib txwm muaj, ua kom lub zog thiab tam sim no nyob rau hauv kab.

Qhov tseeb lom zem: Khaws Qhov Muag ntawm Ob Qhov Kawg

Puas tau xav tias yog vim li cas koj daim nqi hluav taws xob thiaj li raug? Koj tuaj yeem ua tsaug rau CTs thiab PTs hauvmetering transformers. Lawv ua kom paub tseeb tias ob lub tuam txhab hluav taws xob thiab cov neeg siv khoom paub meej npaum li cas hluav taws xob tau siv los ntawm kev nqis tes ua kom raug thiab ntsuas qhov voltage thiab tam sim no. Yog li, yog, PT thiab CT tab tom khaws cov khoom ncaj ncees thiab square ntawm ob qhov kawg ntawm daim phiaj hluav taws xob.

Xaus

Yog li, txawm hais tias nws yog ib qho kev sib kis loj tshaj plaws los yog lub zog ua haujlwm sib faib transformer,PT thiab CTyog cov neeg tsis paub zoo uas ua kom txhua yam khiav zoo. Lawv tswj cov hluav taws xob siab thiab cov hluav taws xob loj heev kom cov tswv lag luam, cov khoom siv hluav taws xob, thiab cov ntsuas tuaj yeem tswj tau lawv yam tsis muaj superhero nplua. Lwm zaus koj tig ntawm lub teeb hloov, nco ntsoov - muaj tag nrho pab pawg neeg saib xyuas hluav taws xob kom paub tseeb tias tam sim no thiab voltage coj lawv tus kheej.
