Peb-theem tshuab tau dav siv hauv kev tsim hluav taws xob, kev xa tawm, kev faib tawm, thiab kev siv hauv kev lag luam. CT xaiv rau peb -theem systems yuav tsum xav txog theem sib npaug, metering txoj kev, kev tiv thaiv txoj kev, thiab kev teeb tsa thaiv. Lub hom phiaj yog kom tau txais cov ntaub ntawv raug tam sim no rau txhua theem thiab, qhov twg yuav tsum tau, rau lub ntiaj teb - nrhiav qhov tsis raug.
Nyob rau hauv tag nrho cov cuab yeej peb -theem system, peb CTs feem ntau yog ntsia, ib qho ntawm txhua theem. Qhov no muab cov ntaub ntawv tiav rau kev ntsuas, kev tiv thaiv, thiab kev saib xyuas. Txhua CT yuav tsum muaj qhov sib piv, cov chav kawm raug, thiab lub nra. Cov yam ntxwv sib txuam yog qhov tseem ceeb rau kev tiv thaiv kev sib txawv thiab kev ntsuas lub zog kom raug. Yog tias ib qho CT txawv ntawm lwm tus, lub kaw lus yuav tsim cov ntawv nyeem tsis raug lossis kev mus ncig tsis raug.
Hauv qee qhov kev siv, tsuas yog siv ob lub CTs xwb. Qhov no tshwm sim hauv cov tshuab sib npaug lossis qhov twg tus nqi thiab qhov chaw txwv. Ob txoj -CT txoj kev tseem tuaj yeem muab cov ntaub ntawv tseem ceeb rau kev ntsuas ntsuas thiab kev tiv thaiv overcurrent, tab sis nws yuav tsis pom txhua yam tsis sib xws. Rau lub ntiaj teb- kev tiv thaiv txhaum cai, yuav tsum muaj kev sib txuas seem lossis ib qho xoom cais- ntu CT.
Qhov piv yuav tsum tau xaiv raws li theem tam sim no. Qhov kev thauj khoom ib txwm yuav tsum poob hauv qhov kev pom zoo ntawm CT thawj qhov ntsuas. Qhov thib ob cov zis yuav tsum sib phim cov meters thiab relays. Burden yuav tsum raug xam rau txhua theem, tshwj xeeb tshaj yog tias cov cable khiav ntev. Qhov tseeb polarity yog qhov tseem ceeb. Rov qab polarity ntawm ib theem tuaj yeem ua rau kev nyeem ntawv tsis raug thiab kev tiv thaiv tsis raug.
Rau kev tiv thaiv, CTs yuav tsum koom tes nrog cov relays. Kev tiv thaiv sib txawv yuav tsum tau sib tw CTs nrog cov yam ntxwv zoo sib xws. Kev tiv thaiv overcurrent yuav tsum muaj qhov txwv qhov tseeb txaus. Lub ntiaj teb- kev tiv thaiv txhaum cai yuav siv lub hauv paus- sib npaug CT lossis qhov seem txuas ntawm peb theem CTs. Txoj kev tiv thaiv yuav tsum tau ua tib zoo kawm.
Kev teeb tsa yuav tsum ua raws li theem kev txheeb xyuas thiab cov kev cai hauv av. Cov CTs yuav tsum tau mounted ruaj ntseg thiab meej meej. Kev ntsuam xyuas yuav tsum txheeb xyuas qhov sib piv, polarity, theem ua ntu zus, thiab lub nra. Tom qab kev teeb tsa, lub kaw lus yuav tsum tau kuaj xyuas kom muaj kev nyeem ntawv sib npaug thiab ntsuas lub zog kom raug.
Hauv kev xaus, xaiv peb -theem CTs los ntawm kev xaiv peb qhov sib luag rau kev ntsuas thiab kev tiv thaiv, lossis ob chav rau cov ntawv thov txwv. Qhov sib piv, qhov tseeb, lub nra, thiab polarity. Xav txog lub ntiaj teb -kev kuaj xyuas qhov yuam kev thiab kev sib koom ua ke. Ib tug tsim raug tsim peb -theem CT system yuav muab cov ntaub ntawv raug thiab kev tiv thaiv txhim khu kev qha.
