PV array DC isolator, tseem hu ua DC disconnect hloov lossis DC rho tawm hloov, yog ib qho cuab yeej siv nyob rau hauv photovoltaic (PV) systems los muab ib txoj kev ntawm disconnecting lub direct tam sim no (DC) lub hwj chim generated los ntawm lub hnub ci vaj huam sib luag los ntawm tus so ntawm lub system.Nws yog ib qho tseem ceeb ntawm kev ruaj ntseg tivthaiv uas tso cai rau cov neeg ua haujlwm saib xyuas lossis cov neeg ua haujlwm thaum muaj xwm txheej ceev kom cais cov PV array los ntawm inverter thiab lwm yam khoom siv rau kev saib xyuas lossis kev daws teeb meem.
Nov yog qee cov ntsiab lus tseem ceeb txog PV array DC isolators:
Lub Hom Phiaj: Lub hom phiaj tseem ceeb ntawm PV array DC isolator yog muab txoj hauv kev nyab xeeb los txiav tawm DC fais fab uas tsim los ntawm cov hnub ci vaj huam sib luag los ntawm cov khoom seem.Nws xyuas kom meej tias tsis muaj lub zog DC nyob rau ntawm lub kaw lus thaum lub sijhawm tu lossis thaum muaj xwm txheej ceev.
Qhov chaw: PV array DC isolators feem ntau yog ntsia ze ntawm lub hnub ci vaj huam sib luag lossis ntawm qhov chaw uas DC xaim los ntawm cov vaj huam sib luag nkag mus rau hauv lub tsev lossis chav tsev khoom.Nws tso cai rau kev nkag tau yooj yim thiab nrawm nrawm ntawm PV array.
Kev ntsuas hluav taws xob: PV array DC isolators raug ntsuas los tswj qhov voltage thiab tam sim no theem ntawm PV system.Cov kev ntsuam xyuas yuav tsum sib phim lossis tshaj qhov siab tshaj plaws voltage thiab tam sim no ntawm PV array kom muaj kev nyab xeeb thiab txhim khu kev qha.
Kev khiav hauj lwm phau ntawv: PV array DC isolators feem ntau manually ua keyboards.Lawv tuaj yeem qhib lossis kaw los ntawm kev hloov pauv lossis tig tus kov.Thaum lub tshuab cais tawm nyob rau hauv qhov chaw tawm, nws tawg DC Circuit Court thiab cais cov PV array los ntawm qhov seem ntawm qhov system.
Kev xav txog kev nyab xeeb: PV array DC cais tawm yog tsim los nrog kev nyab xeeb hauv siab.Lawv feem ntau muaj cov yam ntxwv xws li lub qhov rooj xauv qhov rooj lossis cov ntaub thaiv npog los tiv thaiv kev nkag mus tsis tau lossis cuam tshuam.Qee qhov kev rho tawm kuj tseem muaj cov cim qhia pom los qhia cov xwm txheej ntawm qhov hloov pauv, qhia seb puas yog PV array txuas lossis txiav.
Ua raws li cov qauv: PV array DC cais tawm yuav tsum ua raws li cov qauv thiab cov kev cai, xws li National Electrical Code (NEC) lossis International Electrotechnical Commission (IEC) cov qauv, nyob ntawm qhov chaw txiav txim.Kev ua raws cai kom paub meej tias lub tshuab cais tawm ua tau raws li qhov yuav tsum tau muaj kev nyab xeeb.
Nws yog ib qho tseem ceeb uas yuav tau sab laj nrog tus kws tshaj lij hluav taws xob lossis lub hnub ci teeb tsa thaum xaiv thiab txhim kho PV array DC cais kom paub meej qhov loj me, qhov chaw, thiab ua raws li cov cai thiab cov cai hauv zos,Zoo siab txais tos los tham rau peb rau koj qhov kev thov tshwj xeeb: https://www.cncele.com/
