Ntawm Wuxi GRT Technology Co., Ltd., peb tau saib xyuas kev teeb tsa ntawm ntau tshaj 200 PV tej yaam num-los ntawm cov tsev nyob ru tsev hauv Nyab Laj mus rau kev siv hluav taws xob- nplai arrays hauv Middle East. Thaum cov neeg siv nug txog "kev teeb tsa ua yuam kev," peb tsis hais ib daim ntawv teev npe dav dav. Peb qhia qhov peb tau pom tiag tiag mus tsis ncaj ncees lawm hauv daim teb, thiab qhov kev hloov kho yooj yim li cas tiv thaiv kev ua haujlwm tsis raug nqi. Nov yog qhov yuam kev rov tshwm sim uas peb ntsib, thiab yuav ua li cas kom zam tau lawv.
1. Hla qhov chaw pov thawj ua ntej kev teeb tsa
Qhov yuam kev kim tshaj plaws tshwm sim ua ntej thawj lub bolts yog nruj. Ntawm 1.5 MW kev lag luam retrofit nyob rau hauv Jiangsu xyoo tas los, pawg neeg teeb tsa tuaj txog nrog ua ntej -kitted aluminium rails- tsuas yog nrhiav pom lub ru tsev tau npaj txhij txog HVAC nkag mus thiab cov qauv tsis muaj zog nyob ze ntawm lub teeb pom kev zoo. Peb nres, rov- soj ntsuam nrog laser scanning, thiab kho cov tsheb ciav hlau sib nrug li ob teev. Zaj Lus Qhia: ib txwm ua qhov kev taw qhia zaum kawg nrog cov duab kos hauv tes. Tsis txhob xav tias qhov zoo li - ua tau zoo li tus qauv tsim. Kev txheeb xyuas 30-feeb tuaj yeem txuag tau peb hnub ntawm kev rov ua haujlwm dua.
2. Tsis yog Torque ntawm Fasteners
Hauv qab - torqued bolts loosen nyob rau hauv thermal cycling; dhau - cov torques strip threads lossis crush rail profiles. Ob leeg ua rau ntev - tsis ua haujlwm. Hauv xyoo 2024 kev tshuaj xyuas ntawm tus neeg sib tw 4 MW qhov project, peb pom 18% ntawm cov fasteners yog sab nraud spec-qee qhov ntawm 40% hauv qab no xav tau torque. Ntawm GRT, peb yuav tsum tau ntsuas lub zog torque wrenches thiab qhov chaw random - xyuas ntawm 10% ntawm cov ntsiab lus txuas ua ntej kos npe - tawm. Pro cov lus qhia: kos torqued bolts nrog xim cwj mem rau kev pom QC thaum ua haujlwm.
3. Tsis quav ntsej Thermal Expansion hauv Long Rail Runs
Txhuas nthuav dav ~ 2.4mm ib 'meter' tshaj 50℃kub viav vias. Tsis muaj cov pob qij txha txuas los yog plam- haum cov khoom sib txuas, ntsia hlau buckle, clamps loosen, thiab modules tawg. Nyob rau hauv av -mount project nyob rau hauv Northwest Tuam Tshoj, peb pom qhov no ua ntej: ib tug 30- meter rail khiav uas tsis muaj expansion pub warped thaum lub caij ntuj sov tshav kub. Peb tam sim no suav nrog cov ntawv hlais- haum cov khoom sib txuas hauv txhua qhov kev tsim ua haujlwm ntev thiab qhia txog qhov ntev tshaj plaws uas tsis muaj kev cuam tshuam los ntawm qhov ntsuas kub hauv cheeb tsam.
4. Sib tov cov hlau tsis sib xws tsis muaj kev sib cais
Kev sib cuag ncaj qha ntawm aluminium rails thiab untreated steel fasteners ua rau galvanic corrosion-tshwj xeeb tshaj yog nyob rau hauv ntug hiav txwv dej los yog ib puag ncig ntub. Peb tau pom cov phiaj xwm ua tsis tiav hauv ob xyoos vim qhov kev saib xyuas no. Peb kho: ib txwm suav nrog EPDM lossis nylon cais cov ntxhua khaub ncaws hauv cov khoom sib xyaw- cov khoom sib dhos, thiab qhia meej A2 / A4 stainless hlau fasteners rau kev sib txuas tseem ceeb. Nws yog $0.10 tivthaiv uas tiv thaiv $10,000 hauv kev hloov ua haujlwm.
5. Kev tswj tsis zoo ntawm Cable Thaum Mounting
Routing DC cov xov hlau xoob los yog hla cov kab txuas txuas zoo li lub sijhawm -txuag- txog thaum cua- txav txav ua rau rwb thaiv tsev hnav, ua txhaum hauv av, los yog hluav taws kub. Ntawm ib qhov project, ib pab neeg hla kev tswj xyuas cable kom tau raws li hnub kawg. Rau lub hlis tom qab, ob qhov txhaum hauv av tau taug qab mus rau abraded hlau rwb thaiv tsev. Tam sim no peb muab cov kab txuas ncaj qha rau hauv cov kab tsheb ciav hlau thiab yuav tsum tau xaim kev ruaj ntseg txhua 60cm. Nws ntxiv feeb thaum nruab tab sis tiv thaiv lub hlis ntawm O&M mob taub hau.
6. Saib xyuas cov dej ntws ntawm cov ru tsev tiaj tus
Cov dej sib xyaw ua kom cov txheej txheej degradation thiab tsim cov dej khov hauv cov huab cua txias. Peb tsim me ntsis kev tsheb nqaj hlau qaij (1-2 degree) thiab qhia txog cov dej ntws thaum lub sijhawm teeb tsa-txawm tias nyob rau ntawm lub ru tsev "pas". Ntawm lub tsev khaws khoom logistics hauv Fujian, ntxiv txoj kab nqes me me rau txoj kab tsheb ciav hlau tiv thaiv dej sawv thiab txuas lub neej ntev.
Ib qho yooj yim ua ntej- Daim Ntawv Teev Npe Ua Haujlwm Peb Siv
Ua ntej energizing ib qho system, xyuas:
- Rail alignment nyob rau hauv ± 2mm kam rau ua;
- Fastener torque logged thiab visually cim;
- Grounding continuity tested end-to-end;
- Modules ruaj ntseg nrog txawm clamp siab;
- Cables routed, clipped, thiab tiv thaiv los ntawm UV / puas.
