Thaum teeb tsa lub hnub ci zog system, xaiv hom xaim xaim yog qhov tseem ceeb. Ntau DIY Lub Hnub Ci Zoo Siab xav tsis thoob:Koj puas tuaj yeem siv UF - b hlau rau DC hnub ci?Siv cov hlau tsis ncaj ncees tuaj yeem ua rauZog Lawm, Kev Nyab Xeeb Kev Nyab Xeeb, thiab txawmNEC (National Electrical Code)kev ua txhaum.
Hauv tsab xov xwm no, peb yuav tawg ua dab tsi UF - b hlau yog, vim li cas DC hnub ci hlau muaj tshwj xeeb cov lus nug no. Peb yuav tau piv rau UF {{2} b hlau nrog PV hlau, muab cov lus qhia tswv yim rau kev xaiv cov khoom siv hluav taws xob txoj cai, thiab qhia qhov zoo ntawm kev ua haujlwm nrogDongguan Ntau Ntau Hlau & Cable Co., Ltd., ib tug neeg muab kev ntseeg siab ntawm UL thiab CUL cov khoom muaj ntawv pov thawj.
Dab tsi yog UF - b hlau?
Ua ntej teb rov qab sebUF - b hlauYuav siv tau rau hauv lub hnub ci DC system, nws yog ib qho tseem ceeb kom nkag siab dab tsi UF - b Khwv tau yog.
Zaj piav
UF - b sawv rau"Cov khoom noj nyob hauv av, hom b"Cov. Nws yog hom ntawm- bak cuam hluav taws xob cableTsim los rau sab nraum zoov thiab hauv av cov ntawv thov. Uf - b hlau yog feem ntau siv rauthaj chaw lossis kev faib khoom ua liaj ua teb, tshwj xeeb tshaj yog rau kev siv hluav taws xob sab nraum zoov teeb pom kev zoo, ua haujlwm, chaw ua haujlwm, thiab twj tso kua dej.
Cov ntawv thov uas muaj UF - b hlau

Cov hauv paus ntawm DC Hnub Ci Hluav Taws Xob
Txhawm rau txiav txim siab seb puas yog UF {{0} b hlau yog tsim nyog rau lub hnub ci, nws yog qhov tseem ceeb kom nkag siab qhov kev tsim kho ntawmDC Hnub Ci Hluav Taws Xob.
DC Cov yam ntxwv tam sim no
Hnub ci Panels Tsimncaj qha tam sim no (DC), uas coj tus cwj pwm txawv ntawm tsev neegHloov pauv tam sim no (AC)Cov. Cov yam ntxwv tseem ceeb muaj:
- Nruam Ntws:DC tam sim no tsis tu ncua thiab tuaj yeem tsim cov cua sov ntau dua sijhawm.
- Yuav tsum muaj cov kev xav tau siab:Puas los yog rwb thaiv tsev tsis txaus ntseeg tau yooj yimlub cev, muaj peev xwm ua rau hluav taws.
- Kev txhawj xeeb voltage:Kev ncua ntev dua nce ntxiv thiab lub zog poob, xav tau ceev ceev cov hlau loj xaiv.
Piv txwv li:
Yog hais tias xaim hlau tsis ncaj ncees hom hlau lossis ntsuas yog siv, kev ua haujlwm poob qis, thiab cov khoom siv rhiab xws li inverters lossis maub los puas.
NEC YUAV TSUM RAU HNUB CI ZOG
TusNational Electrical Code (NEC)Teeb tsa cov cai ntshiab rau hnub ci nruab:
- Cov xov hlau yuav tsum yog"Hnub ci tiv taus", high - kub rated, thiabOb Chav Insulatedrau kev nyab xeeb.
- Cov qauv muaj kev pom zoo Solar hlau muaj xws li:
- PV Hlau:Tsim tshwj xeeb rau cov tog hnub ci, nrog kev ntsuas zoo dua thiab kev ntsuas kub siab (90℃lossis 105 degree).
- Siv-2 xaim:Feem ntau siv nruab nrab ntawm hnub ci modules thiab thawv sib tshuam.
- Thhn / thwn-2 xaim:Siv sab hauv lossis ua kev hloov pauv ntawm sab hauv tsev thiab sab nraum zoov.
