Lub tshuab hluav taws xob photovoltaic hloov lub hnub ci zog rau hauv hluav taws xob hluav taws xob. Txawm li cas los xij, lub zog hluav taws xob no txawv ntawm cov hluav taws xob ib txwm siv hluav taws xob vim tias nws yog hluav taws xob ncaj qha (DC) lub zog. Yog li ntawd, yuav tsum muaj cov DC Circuit Court breakers, DC fuses, thiab DC surge protectors yog xav tau los tiv thaiv cov cuab yeej thiab cov kab ke ntawm lub tshuab hluav taws xob photovoltaic. Hauv tsab xov xwm no, peb yuav tham txog cov haujlwm thiab kev siv ntawm cov khoom siv hluav taws xob DC no kom ntxaws.
1. DC Circuit Breakers
DC Circuit Court breakers yog cov cuab yeej tiv thaiv siv los cuam tshuam DC circuits. Lawv lub luag haujlwm tseem ceeb yog kom txiav tawm lub voj voog nyob rau hauv qhov xwm txheej ntawm qhov ua txhaum lossis qhov xwm txheej txawv txav los tiv thaiv kev nyab xeeb ntawm cov khoom siv thiab cov neeg ua haujlwm. Lub luag haujlwm ntawm DC Circuit Court breakers hauv photovoltaic fais fab nroj tsuag zoo ib yam li cov cua hloov hauv AC fais fab nroj tsuag. Hauv kev tiv thaiv hluav taws xob, DC Circuit Court breakers yog cov khoom siv tseem ceeb. Lawv muaj nyob rau hauv ntau yam kev ntsuas tam sim no thiab voltages kom tau raws li qhov kev thov sib txawv.
2. DC Fuses
DC fuses yog cov cuab yeej siv los tiv thaiv DC circuits. Lawv lub luag haujlwm tseem ceeb yog kom txiav tawm lub Circuit Court thaum lub sijhawm dhau los lossis luv luv los tiv thaiv kev nyab xeeb ntawm cov khoom siv thiab cov neeg ua haujlwm. Tsis zoo li DC Circuit Court breakers, DC fuses yog ib qho kev tiv thaiv ib zaug uas yuav tsum tau hloov ib zaug. Hauv photovoltaic fais fab nroj tsuag, DC fuses feem ntau yog ntsia rau ntawm qhov kawg ntawm cov hnub ci vaj huam sib luag los tiv thaiv lub hnub ci vaj huam sib luag thiab lawv cov kab hluav taws xob.
3. DC Surge Protectors
DC surge protectors yog cov khoom siv los tiv thaiv DC circuits. Lawv lub luag haujlwm tseem ceeb yog txwv cov overvoltage mus rau qhov chaw nyab xeeb los tiv thaiv kev nyab xeeb ntawm cov khoom siv thiab cov neeg ua haujlwm thaum muaj overvoltage hauv Circuit Court. DC surge protectors feem ntau yog ntsia rau ntawm qhov kawg ntawm cov khoom siv hnub ci los tiv thaiv lub hnub ci vaj huam sib luag thiab lawv cov kab hluav taws xob. Hauv photovoltaic fais fab nroj tsuag, vim yog ib puag ncig thiab lwm yam laj thawj, cov xwm txheej overvoltage tuaj yeem tshwm sim. Yog li, DC surge protectors yog cov khoom siv tiv thaiv hluav taws xob tseem ceeb heev.
4. Kev Tiv Thaiv Hluav Taws Xob Hluav Taws Xob
Hauv photovoltaic fais fab nroj tsuag, txhua lub hnub ci vaj huam sib luag yuav tsum muaj kev tiv thaiv hluav taws xob ywj pheej. Qhov no txhais tau tias txhua lub hnub ci vaj huam sib luag yuav tsum muaj kev ywj pheej DC Circuit Court breaker, DC fuse, thiab DC surge protector. Cov cuab yeej tiv thaiv no tuaj yeem tiv thaiv kev ua txhaum xws li luv luv Circuit Court, overloads, thiab overvoltages nyob rau hauv lub hnub ci vaj huam sib luag, yog li tiv thaiv kev ruaj ntseg thiab kev ntseeg siab ntawm tag nrho cov system.
5. Kev tiv thaiv hluav taws xob Centralized
Ntxiv nrog rau kev tiv thaiv qib hluav taws xob tiv thaiv, muaj ntau qhov kev tiv thaiv hluav taws xob hauv nruab nrab. Lub hauv paus kev tiv thaiv hluav taws xob txuas tag nrho cov hnub ci vaj huam sib luag hauv cov koob, thiab tom qab ntawd siv lub hauv paus DC Circuit Court breaker, DC fuse, thiab DC surge protector los tiv thaiv tag nrho lub hnub ci vaj huam sib luag series Circuit Court. Qhov kev tiv thaiv hauv nruab nrab no tuaj yeem txo cov khoom siv thiab cov kab, yog li txo tus nqi thiab tsis ua haujlwm ntawm qhov system.
6. Cov qauv kev nyab xeeb hluav taws xob
Rau txhua yam khoom siv hluav taws xob thiab cov kab ke, cov qauv kev nyab xeeb tshwj xeeb yuav tsum tau ua. Hauv cov chaw tsim hluav taws xob photovoltaic, cov qauv no suav nrog IEC 61730 thiab IEC 62109. Cov qauv no qhia txog kev nyab xeeb thiab kev sim rau cov khoom siv hluav taws xob thiab cov tshuab kom ntseeg tau tias muaj kev ruaj ntseg thiab kev nyab xeeb ntawm lub cev.
7. Kev tiv thaiv xob laim rau cov chaw siv hluav taws xob photovoltaic
Txij li cov khoom siv thiab cov tshuab ntawm cov chaw nres tsheb photovoltaic feem ntau yog ntsia rau hauv qhov chaw sab nraum zoov, yuav tsum tau ua ntau yam kev tiv thaiv xob laim. Cov kev ntsuas no suav nrog kev siv av, cov hlua hluav taws xob, cov khoom tiv thaiv hluav taws xob, thiab cov cuab yeej tiv thaiv xob laim. Cov cuab yeej siv thiab thev naus laus zis no tuaj yeem tiv thaiv cov cuab yeej siv thiab cov tshuab ntawm cov chaw siv hluav taws xob photovoltaic los ntawm cov teebmeem ntawm kev puas tsuaj ntuj xws li xob laim.
Hauv cov ntsiab lus, kev tiv thaiv hluav taws xob ntawm cov chaw siv hluav taws xob photovoltaic suav nrog ntau yam khoom siv thiab thev naus laus zis xws li DC Circuit Court breakers, DC fuses, DC surge protectors, module-theem hluav taws xob tiv thaiv, thiab kev tiv thaiv hluav taws xob hauv nruab nrab. Cov cuab yeej siv thiab thev naus laus zis tuaj yeem tiv thaiv cov cuab yeej thiab cov tshuab ntawm cov chaw nres tsheb photovoltaic los ntawm kev ua txhaum thiab kev puas tsuaj ntuj tsim xws li luv luv Circuit Court, overloads, overvoltages, thiab xob laim, yog li txhim kho kev ntseeg siab thiab kev nyab xeeb ntawm lub system.
