Lub qhov rais hom tam sim no transformer yog ib tug tam sim no transformer uas muaj ib tug thib ob winding rwb thaiv tsev los ntawm thiab mus tas li sib sau ua ke ntawm cov hlau nplaum, tab sis tsis muaj thawj winding raws li ib tug tseem ceeb ib feem ntawm nws cov qauv. Hloov chaw, Tus Cwj Pwm Lub Hwj Chim-Txawm yog Cable, Busbar, lossis Lwm Tus Coj Tus Cwj Pwm-Passes Los Ntawm Qhov Chaw Qhib Nruab Nrab, lossis Qhov rai, ntawm Transformer Core, ua haujlwm zoo li ib zaug xwb-Tig thawj qhov cua. Qhov yooj yim thiab elegant tsim no ua rau lub qhov rais CT ib qho ntawm feem ntau siv hom ntawm tam sim no transformer nyob rau hauv hluav taws xob installation thoob ntiaj teb.
Lub hauv paus ntsiab lus ntawm kev khiav hauj lwm ntawm lub qhov rais CT yog nyob ntawm tib lub hauv paus ntsiab lus ntawm electromagnetic induction raws li tag nrho cov tam sim no transformers. Thaum alternating tam sim no ntws los ntawm thawj tus neeg xyuas pib hla lub qhov rais, nws tsim ib qho kev sib nqus sib nqus hauv cov tub ntxhais. Qhov no flux induces ib tug tam sim no nyob rau hauv lub thib ob winding uas yog proportional rau cov thawj tam sim no, scaled los ntawm cov lem ratio. Vim tias thawj tus neeg xyuas pib dhau los ntawm lub qhov rais ib zaug, qhov kev hloov pauv tau zoo yog ib qho, thiab qhov thib ob tam sim no txiav txim siab los ntawm tus lej thib ob.
Qhov rai CTs muaj nuj nqis rau lawv qhov yooj yim, compact loj, thiab tus nqi qis. Lawv feem ntau ntsia tau rau hauv cov chaw tswj lub cev muaj zog, cov keyboards, hluav taws xob faib hluav taws xob, thiab lwm yam khoom siv hluav taws xob tsawg-voltage thiab nruab nrab-voltage. Qhov tsis muaj ib qho tseem ceeb winding txhais tau hais tias tib CT tuaj yeem ua kom haum cov thawj coj sib txawv raws li ntev raws li lawv haum rau hauv lub qhov rais qhib, muab qhov yooj yim hauv kev tsim qauv. Qhov rai CTs kuj muaj nyob rau hauv ntau qhov ntau thiab tsawg ntawm qhov rais, los ntawm cov chav me me nrog qhib ntawm ob peb millimeters mus rau cov chav loj loj nrog qhov rais tshaj 100 millimeters inch.
Ib qho kev xav nrog lub qhov rais CTs yog tias thawj tus neeg xyuas pib yuav tsum tau txiav thiab threaded los ntawm lub qhov rais thaum lub sij hawm installation. Qhov no yuav tsum tau de- ua kom lub zog ntawm lub voj voog thiab tuaj yeem cuam tshuam hauv kev rov ua dua lossis txuas ntxiv - cov ntawv thov txheej txheem. Rau cov xwm txheej no, kev sib cais -core CT- uas tso cai rau cov tub ntxhais kom qhib thiab muab tso rau ib puag ncig tus neeg xyuas pib yam tsis muaj kev cuam tshuam - feem ntau yog qhov kev xaiv zoo dua. Txawm li cas los xij, rau kev txhim kho tshiab uas lub voj voog twb dhau los ua kom muaj zog, qhov rais CTs muaj kev sib xyaw ua ke zoo heev, kev yooj yim, thiab tus nqi- ua tau zoo.
Qhov rai CTs muaj nyob rau hauv ob chav ntsuas ntsuas thiab tiv thaiv qhov tseeb. Kev ntsuas -qib qhov rais CTs feem ntau ua tau raws li cov chav kawm raug ntawm 0.5 lossis 1, ua rau lawv tsim nyog rau kev saib xyuas lub zog thiab kev ntsuas dav dav. Kev tiv thaiv-qib qhov rais CTs tau teev tseg nrog cov chav kawm xws li 5P10 lossis 5P20 kom ntseeg tau tias kev ua haujlwm tau zoo thaum lub sijhawm ua txhaum. Kev tsim kho txuas ntxiv ntawm qhov rais CTs muab cov hlau nplaum sib txuas zoo thiab kev ua haujlwm ruaj khov thoob plaws qhov kev ua haujlwm tam sim no.
Hauv cov ntsiab lus, lub qhov rais hom tam sim no transformer yog ib qho tseem ceeb ntawm lub tsev thaiv kev ntsuas hluav taws xob niaj hnub thiab kev tiv thaiv. Nws txoj kev tsim kho yooj yim, muaj dav, thiab tus nqi qis ua rau nws xaiv qhov kev xaiv rau ntau daim ntawv thov. Cov kws tsim qauv xaiv qhov rais CTs yuav tsum xyuas kom meej tias lub qhov rais qhib qhov loj txaus rau thawj tus neeg xyuas pib, tias cov chav kawm raug thiab lub nra hnyav sib haum rau cov ntawv thov, thiab qhov kev teeb tsa tuaj yeem ua tau nrog lub Circuit Court de-energized.
