1, Kev npaj ua haujlwm
Ua ntej txhim kho lub photovoltaic inverter, nws yog ib qho tsim nyog yuav tsum tau soj ntsuam cov khoom siv hluav taws xob kom ntseeg tau tias nws ua tau raws li qhov kev teeb tsa. Rau kev teeb tsa lub hnub ci cable rau photovoltaic inverters, cov cuab yeej hauv qab no yuav tsum tau npaj:
(1) Cov cuab yeej hluav taws xob: pliers, wrenches, hlau strippers, rwb thaiv tsev riam, thiab lwm yam.
(2) Photovoltaic inverters thiab lawv cov khoom siv hnub ci vaj huam sib luag.
(3) Cov ntaub ntawv kev teeb tsa: hlws ris lub thawv, cable tiv thaiv tube, lub davhlau ya nyob twg thaiv, hnub ci vaj huam sib luag xaim, roj teeb cable, thiab lwm yam.
2, Solar Earth Cable
(1) Rau kev xaiv lub hnub ci lub ntiaj teb cable, nws yog ib qho tsim nyog yuav tsum tau ua cov khoom muag ntawm cov av hauv av muab rau ntawm qhov chaw. Feem ntau, lub peev xwm hauv av ntawm lub inverter yog tsim los ua 0V, thiab qhov zoo tshaj plaws grounding kuj yog tsawg dua 4 Ω.
(2) Txuas lub hnub ci lub ntiaj teb cable mus rau hauv av ntsia hlau rau hauv qab txee ntawm lub inverter thaum tuav lub inverter hloov disconnected, thiab coj nws tawm los ntawm lub cable tiv thaiv tube.
(3) Ua cov xaim hauv av mus rau qhov chaw muaj peev xwm hauv av, txuas lub davhlau ya nyob twg rau hauv av, thiab kho cov xaim hauv av.
3, DC sab
(1) Siv ib rab riam insulating los tev tawm lub raj tiv thaiv ntawm lub hnub ci cable, thiab rub tawm cov txheej rwb thaiv tsev ntawm lub hnub ci hluav taws xob los ntawm 5-10 cm.
(2) Siv cov hlau stripping pliers los tev tawm txheej rwb thaiv tsev ntawm lub hnub ci cable, xaiv lub davhlau ya nyob twg raws li qhov loj ntawm photovoltaic cable, thiab crimp nws. Qhov ntau thiab tsawg ntawm hnub ci DC cables feem ntau siv hauv inverter yog: 4 hli hnub ci cable, 6 hli hnub ci cable, thiab 10mm2 hnub ci cable
(3) Txuas lub hnub ci vaj huam sib luag rau cable tiv thaiv tube, txuas cov txiv neej thiab poj niam kawg ntawm lub hnub ci cable cais, thiab tom qab ntawd kho cov kab hluav taws xob.
(4) Nruab lub DC breaker ntawm qhov tso zis davhlau ya nyob twg ntawm inverter's DC input thiab ceev nws.
4, Kev sib txuas lus sab
(1) Ua ntej txhim kho lub hnub ci xaim xaim, xyuas qhov hluav taws xob thiab lub zog ntawm AC sab, thiab tom qab ntawd xaiv lub hnub ci zog cables thiab cov khoom sib txuas raws li qhov ntsuas hluav taws xob thiab zaus ntawm cov khoom siv.
(2) Siv rab riam insulating los tev tawm cov hlua tiv thaiv kab, thiab rub tawm cov txheej rwb thaiv tsev ntawm lub hnub ci cable DC los ntawm 5-10 cm.
(3) Siv cov hlau stripping pliers los tev tawm lub rwb thaiv tsev txheej ntawm lub hnub ci tooj liab hlau, txuas cov conductors ntawm lub hnub ci MC cable mus rau cov hlau terminals ntawm AC sab interface, thiab kho lawv nrog screws.
(4) Tom qab kev teeb tsa ntawm lub hnub ci cable tiav, siv hluav taws xob rwb thaiv tsev daim kab xev los qhwv cov PV xaim, thiab tom qab ntawd kho nws kom ruaj ntseg.
5, Cov ntsiab lus
Lub installation ntawm lub hnub ci cable inverter yog ib qho txheej txheem nyuaj, thiab ua ntej kev teeb tsa, nws yuav tsum ua tib zoo nyeem cov khoom siv thiab xaiv kom raug thiab siv cov cuab yeej thiab cov khoom siv sib txuas. Los ntawm kev qhia txog kev teeb tsa thiab kev thaiv cov kauj ruam, kuv ntseeg tias txhua tus tau nkag siab txog kev xaim thiab kev ceev faj ntawm photovoltaic inverters, thiab kuv vam tias nws tuaj yeem pab tau rau koj cov kev siv tswv yim hauv kev ua haujlwm.
