01 Kev ceev faj rau kev teeb tsa

Kev teeb tsa hluav taws xob ntawm photovoltaic modules yuav tsum xa mus rau cov kev cai sib xws, nrog rau cov cai tswj hluav taws xob thiab cov kev xav tau ntawm kev sib txuas hluav taws xob. Rau cov ntsiab lus tshwj xeeb, thov hu rau lub tuam tsev fais fab hauv zos.

Thov tsis txhob nruab photovoltaic modules ntawm lub ru tsev yam tsis muaj kev tiv thaiv kev nyab xeeb, suav nrog kev tiv thaiv lub caij nplooj zeeg, ntaiv thiab ntaiv, thiab cov khoom siv tiv thaiv tus kheej. Nyob rau tib lub sijhawm, tsis txhob nruab lossis ua haujlwm faib cov tshuab hluav taws xob photovoltaic hauv qhov chaw tsis zoo, xws li cua daj cua dub thiab cua daj cua dub, ntub dej thiab frosted ru tsev, thiab lwm yam.

Thaum muaj teeb pom kev zoo, lub tshuab hluav taws xob photovoltaic yuav tsim cov hluav taws xob ncaj qha, thiab qhov tam sim no yuav nce ntxiv nrog rau qhov siv ntawm lub teeb. Yog tias koj kov cov hluav taws xob hluav taws xob ntawm cov khoom siv, yuav muaj kev pheej hmoo ntawm hluav taws xob poob lossis kub hnyiab, thiab qhov hluav taws xob ncaj qha ntawm 30 volts lossis siab dua tuaj yeem ua rau tuag taus. Yog li ntawd, nyob rau hauv tus txheej txheem ntawm installation thiab txij nkawm, lub hwj chim mov ntawm lub photovoltaic lub hwj chim tsim system yuav tsum raug txiav tawm, los yog lawv yuav tsum tau tsiv mus nyob rau hauv ib tug tsaus nti ib puag ncig, los yog lub nto ntawm lub Cheebtsam yuav tsum tau them nrog opaque cov ntaub ntawv. Yog tias ua haujlwm hauv lub hnub ci, siv cov cuab yeej insulated thiab tsis txhob hnav cov hniav nyiaj hniav kub.

Txhawm rau kom tsis txhob muaj kev cuam tshuam ntawm arcing thiab hluav taws xob poob siab, tsis txhob cuam tshuam cov kev sib txuas hluav taws xob thaum ua haujlwm hauv kev thauj khoom. Connector plugs yuav tsum tau khaws cia kom qhuav thiab huv si kom ntseeg tau tias lawv ua haujlwm zoo. Tsis txhob ntxig lwm yam khoom siv hlau rau hauv lub ntsaws lossis ua kom muaj hluav taws xob sib txuas hauv lwm txoj kev. Tsis txhob kov lossis kov PV modules nrog cov iav tawg, tshem tawm bezels, thiab cov ntaub ntawv puas, tshwj tsis yog tias lub module tsis txuas hluav taws xob thiab koj hnav cov khoom tiv thaiv tus kheej. Tsis txhob kov cov khoom ntub dej.

02 Design Notes

Photovoltaic modules yuav tsum tau nruab rau hauv cov tsev tsim nyog lossis lwm qhov chaw tsim nyog rau kev teeb tsa module (xws li hauv av, ru tsev, sab facades ntawm tsev, thiab lwm yam); Nws feem ntau pom zoo tias cov qauv photovoltaic yuav tsum tau nruab nrog lub kaum sab xis ntawm ntau dua 10 degrees thiaj li ua si lub luag haujlwm tu tus kheej thaum nws los nag; ib thooj Los yog thaum ntau lub photovoltaic modules yog ib nrab lossis tag nrho ntxoov ntxoo, qhov kev ua tau zoo ntawm lub cev yuav raug txo kom tsawg.

Feem ntau faib, nws raug nquahu kom nruab cov modules nyob rau hauv ib qho chaw tsis muaj qhov ntxoov ntxoo thoob plaws hauv lub xyoo kom nce lub zog tsim hluav taws xob ntawm photovoltaic system. Nyob rau hauv qhov chaw uas xob laim yog nquag, kev tiv thaiv xob laim yuav tsum tau nruab rau cov tshuab photovoltaic.

03 Kev ceev faj rau kev sib txuas hluav taws xob

■ Kev tshuaj xyuas hluav taws xob

Nyob rau hauv cov xwm txheej ib txwm muaj, photovoltaic module tuaj yeem tsim hluav taws xob ntau dua tam sim no thiab qhov hluav taws xob ntau dua li cov qauv ntsuas. Thaum lub photovoltaic modules txuas nrog nyob rau hauv series, lub voltage yog ntxiv; thaum lub photovoltaic modules txuas nrog nyob rau hauv parallel, tam sim no ntxiv; photovoltaic modules nrog cov yam ntxwv ntawm cov hluav taws xob sib txawv tsis tuaj yeem txuas nrog hauv cov koob, thiab kev sib txuas ntawm cov khoom siv hluav taws xob sib txawv ntawm cov khoom siv hluav taws xob photovoltaic tuaj yeem ua rau qhov tsis sib xws ntawm cov hluav taws xob sib txuas. Nruab raws li phau ntawv installation.

Qhov siab tshaj plaws ntawm cov khoom uas tuaj yeem txuas rau hauv cov kab rau txhua kab yuav tsum tau suav raws li cov kev cai cuam tshuam, thiab nws qhov qhib qhov hluav taws xob hluav taws xob tsis tuaj yeem tshaj qhov siab tshaj qhov system voltage tus nqi teev los ntawm cov khoom thiab cov khoom siv hluav taws xob tiv thaiv ntawm lwm cov khoom hluav taws xob DC hauv qab. lub zos xav tau yam tsawg kawg nkaus kub.

Yog tias qhov rov qab tam sim no tshaj qhov siab tshaj plaws fuse tam sim no ntawm cov khoom hla dhau los ntawm cov khoom siv, ib qho khoom siv tiv thaiv overcurrent nrog tib qhov tshwj xeeb yuav tsum tau siv los tiv thaiv cov khoom. Yog hais tias tus naj npawb ntawm kev sib txuas sib txuas ntau dua lossis sib npaug rau 2 txoj hlua, ib qho khoom siv tiv thaiv overcurrent yuav tsum tau nruab rau ntawm txhua txoj hlua ntawm cov khoom.

■ Kev teeb tsa cable thiab thaiv

Photovoltaic modules muaj ob lub teeb hluav taws xob tso zis hluav taws xob, cov terminals uas yog cov khoom txuas, thiab cov plugs no tuaj yeem ua tau raws li qhov yuav tsum tau ua feem ntau.

Qhov zoo cable davhlau ya nyob twg yog ib tug poj niam plug, thiab qhov tsis zoo cable davhlau ya nyob twg yog ib tug txiv neej plug. Kev sib txuas ntawm cov khoom siv tsis yog tsuas yog tsim los rau kev sib txuas ntawm cov module, tab sis kuj tuaj yeem txuas nrog cov khoom siv thib peb nruab nrog cov khoom siv hluav taws xob, thiab kev sib txuas yuav tsum ua raws li phau ntawv qhia ntawm cov khoom tsim khoom.

Thaum cov cables raug kho ntawm lub bracket, nws yog ib qho tsim nyog kom tsis txhob muaj kev puas tsuaj rau cov khoom siv hluav taws xob lossis cov khoom siv. Txhawm rau txhim kho cov cables, koj yuav tsum siv UV-tiv thaiv cov xov hlau thiab cov hlua khi los kho lawv ntawm lub bracket. Nyob rau tib lub sijhawm, sim kom tsis txhob raug tshav ntuj ncaj qha thiab cov dej ntub dej.

■Connector installation

Ua ntej txuas lub connector, kom nws qhuav thiab huv si, thiab xyuas kom meej tias lub connector cover yog ruaj. Nyob rau tib lub sijhawm, tsis txhob tshav ntuj ncaj qha, soaking hauv dej thiab muab lub ntsaws rau hauv av lossis lub ru tsev saum npoo.

Kev sib txuas tsis raug tuaj yeem ua rau muaj kev cuam tshuam arcing thiab hluav taws xob poob siab. Tom qab kev teeb tsa, tag nrho cov kev sib txuas hluav taws xob yuav tsum tau kuaj xyuas kom ruaj khov, thiab tib lub sijhawm, xyuas kom meej tias txhua qhov txuas txuas tau muab tso rau tag nrho.

■ Mechanical kev twb kev txuas thiab installation

General Cheebtsam tau ntawv pov thawj rau txhua yam loads. Static mechanical load uas tuaj yeem tiv taus: qhov siab tshaj plaws tom qab yog 2400Pa (cua siab); Qhov siab tshaj plaws nyob rau pem hauv ntej yog 5400Pa (dawb siab).

Thaum lub sij hawm los yog tom qab kev teeb tsa ntawm photovoltaic modules, thov tsis txhob nqis los yog tso cov khoom hnyav rau ntawm qhov chaw ntawm cov modules, thiaj li tsis ua rau tawg ntawm lub hlwb.

Thaum tsim cov kev txhawb nqa thiab lwm yam khoom siv tshuab, nws yuav tsum muaj peev xwm tiv taus qhov siab tshaj plaws cua siab thiab daus siab.

Thaum xaiv ib txoj kev hauv av, nws yuav tsum tsis txhob ua rau kev sib cuag ncaj qha ntawm tus ncej ntawm photovoltaic module thiab lwm yam hlau, yog li kom tsis txhob muaj qhov tshwm sim ntawm hluav taws xob corrosion.

Yuav kom tswj tau qhov hluav taws kub ntsuas, qhov kev ncua deb ntawm lub iav nto ntawm lub photovoltaic module thiab lub ru tsev saum npoo yuav tsum yog tsawg kawg yog 10cm. Qhov kev ncua deb ntawm cov uas nyob ib sab photovoltaic modules yuav tsum yog tsawg kawg yog 2cm.
