Cov tshuab Switchgear xav tau CTs uas ua tau raws li cov khoom siv hluav taws xob, kev siv tshuab, thiab kev nyab xeeb. Switchgear yog siv los tswj, tiv thaiv, thiab cais cov khoom siv hluav taws xob, thiab CTs hauv nws yuav tsum muaj kev ntseeg siab nyob rau hauv ib txwm muaj thiab ua txhaum. Kev xaiv yuav tsum xav txog cov chav kawm voltage, rwb thaiv tsev, kev teeb tsa busbar, luv luv - kev ntsuas hluav taws xob, kev sib koom ua ke, thiab lub cev qhov ntev.
Thawj kauj ruam yog los txiav txim siab qhov system voltage thiab rwb thaiv tsev theem. Nruab nrab-voltage switchgear yuav ua haujlwm ntawm 11 kV, 33 kV, lossis siab dua, thaum qis -voltage switchgear ua haujlwm ntawm 400 V, 690 V, lossis zoo sib xws. CT yuav tsum muaj cov rwb thaiv tsev tsim nyog thiab dielectric zog rau qhov system voltage. Kev ua haujlwm tawm ib nrab yog qhov tseem ceeb hauv qhov nruab nrab - cov ntawv siv hluav taws xob, vim tias kev rwb thaiv tsev tsis zoo tuaj yeem ua rau tsis ua haujlwm.
Thawj qhov tam sim no thiab qhov sib piv yuav tsum raug xaiv raws li qhov kev thauj khoom thiab qhov txhaum tam sim no. CT yuav tsum ua haujlwm siab tshaj plaws tam sim no thiab luv luv -lub sijhawm thermal tam sim no. Qhov ntsuas tam sim no dynamic yuav tsum txaus rau qhov ua txhaum tam sim no. Rau kev tiv thaiv, qhov raug txwv qhov tseem ceeb thiab lub hauv caug taw tes voltage yuav tsum phim cov relay yuav tsum. Rau metering, cov chav kawm raug thiab lub nra yuav tsum tsim nyog.
Busbar thiab mounting qhov ntev yog qhov tseem ceeb. Switchgear compartments feem ntau compact, yog li CT yuav tsum haum rau qhov chaw muaj. Busbar- hom CTs muaj ntau vim tias lawv tso cai rau lub busbar hla lub hauv paus. Lub CT yuav tsum tau teeb tsa kom ruaj ntseg thiab raug qhov chaw kom tsis txhob flashover. Cable- hom CTs tuaj yeem siv rau cov khoom siv hluav taws xob.
Cov kab mob thiab kab mob yuav tsum tau txiav txim siab. CT yuav tsum muab cov relays, ntsuas, thiab saib xyuas cov cuab yeej tsis pub dhau nws lub nra hnyav. Cov kab txuas txuas txuas ntev ntev ua rau lub nra hnyav, yog li tus neeg xyuas pib qhov loj me thiab txoj kev yuav tsum tau kuaj xyuas. Qhov tseeb polarity thiab grounding yog qhov tseem ceeb. Secondary Circuit Court yuav tsum tsis txhob qhib nyob rau hauv load.
Cov qauv thiab kev xeem yog qhov tseem ceeb. CT yuav tsum ua raws li IEC, IEEE, lossis lwm yam qauv. Cov kev ntsuam xyuas ntawm lub Hoobkas thiab qhov chaw kuaj xyuas yuav tsum txheeb xyuas qhov sib piv, polarity, rwb thaiv tsev, thiab lub nra. Cov kev tshawb fawb txog kev sib koom tes sib txuas yuav tsum paub meej tias CT kev ua tau zoo txaus rau txoj kev tiv thaiv.
Hauv kev xaus, xaiv lub switchgear CT los ntawm kev txiav txim siab voltage, rwb thaiv tsev, tam sim no, piv, tiv thaiv chav kawm, ntsuas qhov tseeb, lub nra, qhov ntev, thiab cov qauv. Ib tug raug xaiv CT yuav ua kom muaj kev nyab xeeb thiab txhim khu kev qha ua haujlwm ntawm lub switchgear system.
