Ntawm Wuxi GRT Technology Co., Ltd., peb tau kawm tias cua thiab daus loads tsis yog kab ntawm cov qauv qhia ntawv xwb -lawv dictate bracket thickness, rail spacing, foundation tob, thiab tej zaum tag nrho cov mounting lub tswv yim. Thaum EPC cov neeg cog lus nug seb cov tub rog no zoo li cas hnub ci racking tsim, peb tsis hais cov qauv hauv phau ntawv. Peb qhia qhov peb tau ntsuas, kho, thiab siv tau rau ntawm qhov chaw tiag tiag.
Cua Load: Nws tsis yog qhov siab xwb -Nws yog Uplift
Feem ntau cov neeg xav tias cua thawb lub panels cia. Hauv kev muaj tiag, cua uplift yog thawj hom tsis ua haujlwm rau qis- qaij thiab tiaj tus-ru tsev arrays. Raws li huab cua ntws hla thiab hauv qab modules, nws tsim tsis zoo siab uas sim tev lub kaw lus tawm ntawm lub ru tsev lossis hauv av.
Ntawm 3.2 MW ntug hiav txwv dej hauv Fujian, peb qhov kev teeb tsa thawj zaug siv tus qauv nruab nrab -clamps ntawm 1.2m ib ntus. Cua simulation (raws li ASCE 7-22 thiab cov ntaub ntawv typhoon hauv zos) tau nthuav tawm vortex los ntawm qhov chaw ib puag ncig, nce kev nce siab ze li 30% ntawm ntug kab. Es tsis txhob dhau- engineering tag nrho cov kab ke, peb tau ntxiv dag zog rau ib puag ncig nrog hnyav- lub luag haujlwm kawg brackets, txo ntug clamp qhov sib nrug mus rau 0.9m, thiab ntxiv qis -profile aerodynamic deflectors. Tus nqi kho vajtse tau nce los ntawm ~ 6%, tab sis lub kaw lus tuav xoom tsis ua tiav los ntawm ob lub caij typhoon. Cua tsim tsis yog hais txog kev ntxiv cov hlau-nws yog hais txog kev tso nws qhov chaw physics xav tau nws.
Snow Load: Nyhav, Drift, thiab zawv zawg qhov tseem ceeb
Kev suav cov daus daus mus dhau qhov hnyav li qub. Hauv cov huab cua txias, cov qauv sib txuam hloov vim cua drifts, ru tsev thaiv, thiab vaj huam sib luag qaij. Tsawg- qaij arrays (<15°) trap snow; steeper arrays encourage sliding, which can overload lower rows or damage cables.
Rau 2 MW hauv av-mount nyob rau hauv Hebei, lub hauv paus tsim tau suav tias yog cov daus sib faib. Thaum thawj lub caij ntuj no, cov kev ntsuas infrared tau pom qhov tsis sib xws: cov khoom sib tsoo tau tsim tom qab cov khoom siv, thiab ib nrab melting / refreezing tsim cov dej khov nab kuab raws cov ntug kev tsheb nqaj hlau. Peb tau teb los ntawm kev kho dua tshiab purlin ntsuas, ntxiv polyethylene snow guards los tswj swb tshaj tawm, thiab nce lub hauv paus embedment qhov tob los ua ke ntsug thiab sab shear. Tom qab- kev hloov kho saib xyuas pom qhov ruaj khov deflection nyob rau hauv ± 3mm-zoo nyob rau hauv module warranty txwv.
Yuav ua li cas peb ua tau validate Load Capacity
Software qauv yog qhov pib, tsis yog qhov kawg. Ntawm GRT, peb cov haujlwm ua haujlwm engineering suav nrog:
- Site-cov ntaub ntawv huab cua tshwj xeeb: 50-xyoo cua / daus cov ntaub ntawv rov tshwm sim, tsis yog qhov nruab nrab hauv cheeb tsam;
- FEA kev ntsuam xyuas kev ntxhov siab: Cov ntsiab lus ntawm cov khoom lag luam bracket, rail deflection nyob rau hauv kev sib xyaw ua ke, thiab cov hlua khi;
- Kev lees paub lub cev: Kev ntsuas qhov ntsuas qhov ntsuas tom qab thermal cycling, thiab rub- tawm/uplift pov thawj ntawm cov qauv hauv paus;
- Kev sib raug zoo Code: GB 50009, ASCE 7, lossis EN 1991-1-4, nyob ntawm qhov project qhov chaw.
Peb tau pom ntau txoj haujlwm ua tsis tiav vim cov neeg tsim qauv tso siab rau cov khoom siv "tus qauv" tshwj xeeb. Lub mounting system ntsuas rau 45 m / s hauv av yuav zoo li ua tsis tau zoo ntawm 55 m / s ntawm ntug dej hiav txwv tsis muaj qhov txuas ntxiv thiab kev tiv thaiv corrosion.
Kev Qhia Ncaj Ncees ntawm Kev Lag Luam -Offs
Yog tias koj lub xaib ntsib cov khoom sib xyaw ua ke (siab cua + daus hnyav), peb tuaj yeem pom zoo cov hauv paus hybrid, kho lub kaum sab xis, lossis cov ntaub ntawv txuas ntxiv. Peb yuav qhia rau koj ua ntej yog tias tus nqi -txuag shortcut cuam tshuam rau lub sijhawm ntev - kev ntseeg siab. Peb lub hom phiaj tsis yog muag qhov hnyav tshaj plaws - nws yog los tsim kom muaj lub teeb pom kev zoo tshaj plaws uas tseem ua tau raws li koj lub hom phiaj kev nyab xeeb thiab tawm los.
Cia peb sib xyaw Engineering nrog koj qhov chaw muaj tiag
Yog tias koj tab tom ua tiav PV layout thiab xav tau cov qauv siv tau rau cua lossis daus, qhia koj qhov chaw sib koom ua ke, lub ru tsev / av specs, thiab lub hom phiaj qaij lub kaum ntse ntse nrog peb pab pawg engineering. Ntawm Wuxi GRT Technology, peb muab cov kev suav load, cov ntaub ntawv qhia txog kev ntxhov siab, thiab kev teeb tsa torque specs - yog li koj qhov kev teeb tsa ua haujlwm tau zoo li tsim, tsis yog raws li tau hais tseg. Xa koj cov ntaub ntawv qhov project, thiab cia peb sib koom ua ke- txhim kho racking kev daws teeb meem uas tiv taus huab cua tiag tiag, tsis yog cov kev xav ntawm daim ntawv teev lus xwb.
