Taw qhia
Tam sim no transformer (CT) yog ib qho khoom siv hluav taws xob tseem ceeb siv los ntsuas thiab saib xyuas tam sim no hauv cov tshuab hluav taws xob. Nws tso cai rau cov hluav taws xob hluav taws xob siab kom ntsuas kev nyab xeeb los ntawm kev hloov lawv mus rau hauv ib qho me me, sib npaug tam sim no uas tuaj yeem siv los ntawm meters, cov cuab yeej saib xyuas, thiab kev tiv thaiv relays. Tam sim no transformers yog dav siv nyob rau hauv lub hwj chim tis systems, industrial khoom, switchgear, hluav taws xob metering, thiab tiv thaiv daim ntaub ntawv.
Hauv ntau qhov kev teeb tsa hluav taws xob, qhov tam sim no ntws los ntawm tus neeg xyuas pib tuaj yeem siab dhau rau tus qauv ntsuas ntsuas los txuas ncaj qha. Lub tshuab hluav taws xob tam sim no muab cov kev daws teeb meem los ntawm hluav taws xob cais cov ntsuas hluav taws xob los ntawm qhov siab -tam sim no thawj Circuit Court thaum tsim hluav taws xob ntsuas theem nrab.
Kev nkag siab txog qhov tam sim no transformer ua haujlwm yog qhov tseem ceeb thaum xaiv, txhim kho, thiab siv CTs hauv qhov hluav taws xob.
Tam sim no Transformer yog dab tsi?
Lub transformer tam sim no yog ib hom twj tso kua mis transformer tsim los txo qhov siab thawj tam sim no mus rau qis dua theem nrab tam sim no uas tsim nyog rau kev ntsuas lossis cov cuab yeej tiv thaiv.
Ib qho CT ib txwm muaj lub hauv paus hauv Circuit Court, ib tug sib nqus core, thiab ib tug thib ob winding. Thawj sab yog ntsuas qhov ntsuas tam sim no, thaum sab nraud txuas nrog lub ntsuas ntsuas, ntsuas lub zog, ntsuas ntsuas, lossis tiv thaiv relay.
Piv txwv li, CT nrog qhov sib piv ntawm 500 / 5A yog tsim los kom cov thawj tam sim no ntawm 500A sib haum mus rau qhov thib ob tam sim no ntawm 5A nyob rau hauv cov xwm txheej ntsuas. Qhov no tso cai rau cov cuab yeej tsim los rau qhov tam sim no me me los saib xyuas cov hluav taws xob loj dua.
CT piv, qhov tseeb, lub nra, qib rwb thaiv tsev, thiab daim ntawv thov yuav tsum yog qhov tseem ceeb thaum xaiv lub tshuab hloov tam sim no.
Tam sim no Transformer ua haujlwm li cas?
Lub transformer tam sim no ua haujlwm raws li lub hauv paus ntsiab lus ntawm electromagnetic induction.
Thaum alternating tam sim no ntws los ntawm thawj tus neeg xyuas pib, nws tsim ib qho chaw sib nqus nyob ib ncig ntawm tus neeg xyuas pib. Qhov no magnetic teb dhau los ntawm CT's magnetic core thiab induces ib tug tam sim no nyob rau hauv lub thib ob winding.
Qhov thib ob tam sim no yog proportional rau thawj tam sim no raws li tus transformer tus nqi piv. Yog tias thawj qhov tam sim no nce, qhov thib ob tam sim no kuj nce proportionally nyob rau hauv ib txwm ua haujlwm ntawm CT.
Piv txwv li, nrog 1000 / 5A tam sim no transformer, thawj qhov tam sim no ntawm 1000A sib raug rau kwv yees li 5A ntawm ob sab. Ntawm 500A thawj tam sim no, qhov thib ob tam sim no yuav yog kwv yees li 2.5A raws li qhov zoo tagnrho.
Qhov kev hloov pauv no ua rau nws tuaj yeem saib xyuas cov dej ntws loj yam tsis muaj kev sib txuas ncaj qha rau siab -tam sim no tus neeg xyuas pib rau cov cuab yeej ntsuas ntsuas.
Cov Cheebtsam tseem ceeb ntawm Transformer tam sim no
Txawm hais tias CT designs txawv nyob ntawm daim ntawv thov, feem ntau tam sim no transformers muaj ob peb yam tseem ceeb.
Cov tub ntxhais hlau nplaum muab txoj hauv kev rau cov hlau nplaum sib nqus tsim los ntawm thawj qhov tam sim no. Cov qauv tsim muaj qhov cuam tshuam loj rau qhov raug thiab ua haujlwm ntawm CT.
Thawj tus neeg xyuas pib lossis winding nqa cov tam sim no uas yuav tsum tau ntsuas. Nyob ntawm hom CT, lub hauv paus yuav ua tau - nyob rau hauv winding, bar, los yog tus neeg xyuas pib dhau los ntawm CT qhib.
Qhov thib ob winding ua rau qis tam sim no txuas nrog cov ntsuas, cov cuab yeej saib xyuas, lossis cov cuab yeej tiv thaiv.
Cov txheej txheem rwb thaiv tsev cais cov hluav taws xob hluav taws xob thiab pab lub tshuab hluav taws xob tiv thaiv qhov yuav tsum tau ua haujlwm voltage thiab hluav taws xob kev ntxhov siab.
Qhov twg tam sim no Transformers siv?
Tam sim no transformers yog siv nyob rau hauv ntau yam kev siv hluav taws xob. Hauv kev faib hluav taws xob, CTs tuaj yeem siv rau kev ntsuas tam sim no, kev saib xyuas lub zog, thiab kev tiv thaiv kab ke.
Hauv switchgear, tam sim no transformers tuaj yeem muab cov teeb liab tam sim no rau kev tiv thaiv relays kom kuaj tau cov hluav taws xob txawv txav.
Hauv cov chaw tsim khoom, CTs feem ntau yog siv los saib xyuas lub cev muaj zog, hluav taws xob vaj huam sib luag, cov khoom siv tsim khoom, thiab lwm yam siab - tam sim no loads.
Lawv kuj tau siv dav hauv cov tshuab ntsuas hluav taws xob. Los ntawm kev muab ib qho kev faib ua feem thib ob tam sim no, CT tso cai rau lub ntsuas hluav taws xob ntsuas hluav taws xob hauv cov tshuab uas cov khoom siv tam sim no siab dhau rau kev sib txuas ncaj qha.
Vim li cas tam sim no Transformers tseem ceeb?
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm lub tshuab hloov tam sim no yog tias nws ua rau siab - ntsuas tam sim no ua tau zoo dua thiab muaj kev nyab xeeb dua. Hloov chaw txuas lub ntsuas ntsuas ncaj qha mus rau qhov siab - tam sim no Circuit Court, lub ntsuas hluav taws xob tuaj yeem tau txais qhov txo qis tam sim no los ntawm CT thib ob Circuit Court.
CTs kuj tseem tuaj yeem muab hluav taws xob cais tawm ntawm qhov siab -tam sim no thawj Circuit Court thiab ntsuas lossis tiv thaiv Circuit Court. Qhov no tseem ceeb tshwj xeeb hauv kev lag luam thiab kev siv hluav taws xob faib hluav taws xob.
Txawm li cas los xij, kev xaiv CT thiab kev teeb tsa kom zoo yog qhov tseem ceeb. CT piv yuav tsum phim daim ntawv thov, thiab cov chav kawm raug thiab lub nra yuav tsum tsim nyog rau cov khoom sib txuas.
Xaus
Lub transformer tam sim no yog ib qho tseem ceeb rau kev ntsuas tam sim no, kev saib xyuas, thiab kev tiv thaiv hauv cov tshuab hluav taws xob. Nws ua haujlwm los ntawm electromagnetic induction los hloov lub siab tseem ceeb tam sim no rau hauv ib qho me me proportional secondary tam sim no.
Los ntawm kev xaiv qhov tseeb CT piv, cov chav kawm raug, lub nra, qib rwb thaiv tsev, thiab hom kev tsim kho, cov neeg siv tuaj yeem ua tiav kev ntsuas tam sim no thiab kev tiv thaiv hluav taws xob zoo.
Rau kev faib hluav taws xob, cov cuab yeej siv hluav taws xob, cov khoom siv hluav taws xob, thiab kev siv lub zog ntsuas hluav taws xob, xaiv lub tshuab hluav taws xob tam sim no raws li qhov xav tau hluav taws xob tiag tiag yog qhov tseem ceeb rau kev ua haujlwm ntev - thiab ntsuas qhov tseeb.
