Tam sim no transformers, feem ntau hu uaCTs, yog cov khoom tseem ceeb hauv lub tshuab fais fab.Nws ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv thiab ntsuas kev siv, tsis zoo li cov transformers zoo tib yam.Hauv tsab xov xwm no, peb yuav tshawb txog qhov sib txawv ntawm CTs thiab cov transformers zoo tib yam thiab kawm seb CTs siv li cas rau kev tiv thaiv.
Ua ntej, cia peb delve rau hauv qhov sib txawv ntawm CT thiab cov pa transformers.Traditional transformers feem ntau yog tsim los hloov hluav taws xob hluav taws xob ntawm circuits los ntawm kev nce lossis txo qhov voltage.Feem ntau siv nyob rau hauv kev sib faib tes hauj lwm, voltage yog nce mus rau kis tau tus mob nyob ntev thiab voltage yog nqis los rau cov neeg siv.
Piv txwv li,tam sim no transformerstshwj xeeb yog tsim los ntsuas lossis saib xyuas cov dej ntws tam sim no hauv hluav taws xob hluav taws xob.Nws ua hauj lwm ntawm lub hauv paus ntsiab lus ntawm electromagnetic induction, zoo ib yam li ib tug zoo tib yam transformer.Txawm li cas los xij, thawj winding ntawm CT muaj ib zaug tig los yog ob peb lem, tso cai rau nws txuas nrog cov khoom siv tam sim no.Qhov no tsim enables lubCTntsuas cov dej ntws siab uas tsis muaj hluav taws xob tseem ceeb.Qhov thib ob winding ntawm CT feem ntau yog ntsuas rau qhov qis dua, uas ua rau lub ntsuas hluav taws xob lossis cov cuab yeej tiv thaiv zoo dua.
Tam sim no, cia peb mus rau qhov tseem ceeb ntawm CT hauv kev tiv thaiv daim ntawv thov.CT yog siv dav hauv cov tshuab hluav taws xob los xyuas kom muaj kev nyab xeeb ntawm cov khoom siv, circuits thiab cov neeg ua haujlwm.Lawv ua lub luag haujlwm tseem ceeb hauv kev txheeb xyuas qhov tsis raug, overcurrents thiab kev ua haujlwm tsis zoo.Los ntawm kev ntsuas tam sim no kom raug, CT ua rau cov cuab yeej tiv thaiv uas cais qhov tsis raug ntawm qhov seem ntawm qhov system, tiv thaiv kev puas tsuaj ntxiv.
Ib qho khoom siv tiv thaiv uas siv ua ke nrog CTs yog arelay.Lub relay yog lub luag haujlwm rau kev saib xyuas tus nqi tam sim no thiab pib qhib lossis kaw ntawm Circuit Court breaker raws li tau teev tseg thiab cov xwm txheej.Piv txwv li, yog hais tias ib tug luv luv Circuit Court los yog ntau tshaj tam sim no tshwm sim, ib tug relay ntes no anomaly thiab xa ib tug mus txawv tebchaws teeb liab mus rau lub Circuit Court breaker.CTxyuas kom meej tias covrelaytau txais qhov tseeb sawv cev ntawm qhov tam sim no ntws los ntawm Circuit Court, uas ua rau muaj kev tiv thaiv txhim khu kev qha.
CTskuj tseem siv los ntsuas thiab saib xyuas cov ntsuas hluav taws xob.Hauv cov tshuab fais fab, nws yog ib qho tseem ceeb kom paub qhov tseeb npaum li cas ntawm tam sim no ntws los ntawm ntau yam circuits.CT tso cai rau kev ntsuas qhov tseeb, ua kom muaj kev tswj hwm lub zog thiab sib npaug.Cov kev ntsuas no tuaj yeem siv rau kev them nqi, kev tswj xyuas hluav taws xob thiab kev tiv thaiv kev saib xyuas.
Tsis tas li ntawd, CTs tau siv dav hauv kev siv tshuab thiab tshuab nrog cov khoom siv hluav taws xob loj.Lawv muab ib txoj hauv kev los saib xyuas cov qib tam sim no thiab txheeb xyuas cov kev tsis sib xws, xws li lub cev muaj zog overloading lossis voltage poob.Los ntawm kev txheeb xyuas cov teeb meem no sai, kev tiv thaiv tuaj yeem raug coj los ua kom tsis txhob muaj cov khoom siv kim heev lossis kev poob qis.
Hauv cov ntsiab lus, txawm hais tias ob qho tib si CT thiab niaj zaus transformers ua haujlwm ntawm lub hauv paus ntsiab lus ntawm electromagnetic induction, lawv ua haujlwm sib txawv.CTs yog tsim los rau kev ntsuas tam sim no thiab kev tiv thaiv daim ntawv thov.Nws cov qauv tsim tshwj xeeb tso cai rau nws ntsuas qhov ntsuas tam sim no kom raug thaum muab kev nyab xeeb, cais tawm rau kev ntsuas thiab cov cuab yeej tiv thaiv.Txawm hais tias kuaj xyuas qhov tsis raug, ua kom muaj kev nyab xeeb hluav taws xob lossis saib xyuas kev siv hluav taws xob, CT ua lub luag haujlwm tseem ceeb hauv cov tshuab hluav taws xob niaj hnub no.Nws muaj peev xwm nyeem tau tam sim no thiab txhim khu kev qha ua rau nws yog ib qho tseem ceeb hauv kev lag luam thiab kev siv ntau yam.
