Dab tsi yog photovoltaic faib txee?
Lub txee faib khoom yog lub txee rau hauv lub tshuab hluav taws xob uas yog lub luag haujlwm rau kev faib hluav taws xob hluav taws xob thiab cov kab hluav taws xob, saib xyuas cov khoom siv hluav taws xob, thiab sib xyaw cov khoom siv hluav taws xob rau kev tswj.
Lub thawv xa khoom feem ntau muaj lub thawv lub cev, cov hluav taws xob hluav taws xob, tus kheej rov pib dua hluav taws xob thiab cov hluav taws xob tiv thaiv hluav taws xob, cov tiv thaiv hluav taws xob, cov hluav taws xob tiv thaiv hluav taws xob rau cov hluav taws xob tiv thaiv hluav taws xob, thiab cov hluav taws xob sib cais.
Cov khoom siv hauv lub thawv feem ntau yog stainless hlau lub thawv thiab galvanized ntawv lub thawv. Qhov zoo ntawm stainless hlau lub thawv lub cev yog xeb thiab tiv thaiv corrosion, waterproof thiab plua plav, ruaj khov thiab ruaj khov, yooj yim installation, thiab lwm yam; Qhov zoo ntawm galvanized sheet hlau lub thawv yog xeb thiab tiv thaiv corrosion, zoo nkauj thiab ruaj khov tsos, thiab tus nqi qis.
Lub luag haujlwm tseem ceeb ntawm lub tshuab hluav taws xob yog txiav tawm lub voj voog tom qab luv luv los yog overload. Raws li qhov voltage, nws muab faib ua ib theem 220V thiab peb-theem 400V. Cov kev qhia tshwj xeeb xws li 16A, 25A, 32A, 40A, 50A, thiab 63A raug xaiv raws li qhov ntsuas tam sim no.
Lub npe tag nrho ntawm residual tam sim no tus tiv thaiv yog residual tam sim no tiv thaiv ntaus ntawv, uas feem ntau pom txawv txav tam sim no los ntawm residual tam sim no tiv thaiv ntaus ntawv los siv residual tiv thaiv tam sim no.
Kev ua haujlwm ntawm tus kheej rov pib dua overvoltage thiab undervoltage protector yog kom txiav tawm (nrog lub teeb liab ntawm kev tiv thaiv) thaum cov kab hluav taws xob ntau tshaj nws tus kheej tiv thaiv, yog li txiav tawm lub hwj chim; Thaum cov kab hluav taws xob raug kuaj pom kom rov qab mus rau qhov qub, nws tuaj yeem kaw.
Surge protector, tseem hu ua hluav taws xob ntes, hluav taws xob ntes, thiab lwm yam, yog cov khoom siv hluav taws xob uas muaj kev tiv thaiv kev nyab xeeb rau ntau yam khoom siv hluav taws xob, cov cuab yeej siv, thiab cov kab sib txuas lus. Lub hauv paus ntsiab lus ua haujlwm yog tias thaum muaj hluav taws xob tam sim no lossis qhov hluav taws xob tam sim ntawd tshwm sim hauv hluav taws xob lossis kab sib txuas lus vim muaj kev cuam tshuam sab nraud, tus tiv thaiv hluav taws xob tuaj yeem ua thiab hloov mus rau lub sijhawm luv luv, zam kev puas tsuaj rau lwm yam khoom siv hauv Circuit Court tshwm sim los ntawm kev tawg. .
Kev rho tawm cov hloov pauv thiab cov riam hloov tuaj yeem ua kom ntseeg tau tias muaj kev sib cais ntawm lub inverter thiab daim phiaj hluav taws xob nyob rau hauv qhov xwm txheej ntawm photovoltaic system tsis ua hauj lwm lossis txij nkawm.
Cov khoom siv hluav taws xob photovoltaic tau muab faib ua DC faib khoom thiab AC faib khoom raws li qhov hluav taws xob waveforms.
Lub DC faib txee feem ntau yog siv los hloov DC lub zog tawm tswv yim los ntawm cov khoom siv hluav taws xob photovoltaic thiab txuas lawv mus rau inverters lossis ncaj qha muab lwm yam DC loads (xws li roj teeb, them lub zog, thiab lwm yam). Cov kev soj ntsuam ntse tuaj yeem tsim kho raws li qhov xav tau los kuaj xyuas qhov hluav taws xob thiab tam sim no ntawm txhua qhov sib txuas sib txuas, ua kom yooj yim rau kev tswj hwm.
Lub luag haujlwm tseem ceeb ntawm cov khoom sib txuas lus hauv lub chaw nres tsheb fais fab photovoltaic yog hloov cov inverter thaub qab, xyuas kom lub zog ib txwm muaj ntawm lub tshuab hluav taws xob photovoltaic, thiab kuj ntsuas lub zog hluav taws xob ntawm kab.
Nyob rau tib lub sijhawm, photovoltaic AC faib txee yog nruab nrog kev tiv thaiv xob laim, tsim hluav taws xob, thiab ntsuas hluav taws xob raws li cov neeg siv khoom siv tiag tiag thiab cov khoom siv hluav taws xob ntawm photovoltaic system. Nws tseem tau nruab nrog cov ntsuas hluav taws xob ntse thiab sib txuas lus nrog kev saib xyuas los ntawm RS485.
Muaj ntau txoj kev teeb tsa rau lub thawv xa khoom:
Kev teeb tsa phab ntsa yog kho lub thawv xa khoom ntawm phab ntsa. Txoj kev teeb tsa no yuav tsum xav txog lub peev xwm thauj khoom ntawm phab ntsa thiab seb cov khoom siv thiab cov qauv ntawm phab ntsa puas tsim nyog rau kev teeb tsa. Feem ntau, tsev neeg photovoltaic lossis me me photovoltaic fais fab nroj tsuag yuav siv phab ntsa.
Bracket installation yog rau nruab lub thawv xa khoom ntawm lub bracket kom yooj yim xaim thiab tu. Feem ntau siv rau loj-scale photovoltaic fais fab nroj tsuag.
Kev teeb tsa hauv av yog hais txog kev tso lub txee rau hauv av, suav nrog kev tsim kho vaj tse, thiab tsim nyog rau cov chaw nres tsheb loj.
Lub thawv xa khoom xav tau qhov cua zoo kom tiv thaiv cov khoom siv los ntawm kev kub dhau. Thaum txhim kho lub thawv xa khoom, nws yuav tsum xav txog seb puas muaj qhov chaw txaus nyob ib puag ncig nws thiab seb puas muaj qhov qhib qhov cua txaus.
Txawm hais tias nws yog phab ntsa lossis bracket installation, nws yuav tsum tau ua kom ruaj khov thiab tiv thaiv kev co. Thaum txhim kho lub thawv xa khoom, nws yog ib qho tsim nyog los xyuas kom meej tias cov khoom siv thiab cov qauv ntawm lub bracket tuaj yeem tiv taus qhov hnyav ntawm lub thawv xa khoom thiab tiv thaiv kev cuam tshuam ntawm ib puag ncig sab nraud.
Thaum txhim kho lub thawv xa khoom, nws yuav tsum tau sau npe rau txhua lub cable thiab cov khoom siv, thiab qhia meej cov lus qhia ntawm lub thawv xa khoom. Qhov no tuaj yeem pab txhawb kev txij nkawm thiab kev ua haujlwm yav tom ntej, zam kev ua yuam kev los ntawm kev sau ntawv tsis meej.
