Nyob rau hauv lub hnub ci project, feem ntau cov xim mus rau modules, inverters, mounting lug, thiab tag nrho cov nqi ntsia. Qhov ntawd yog qhov nkag siab: lawv yog qhov pom tshaj plaws thiab siab tshaj plaws - tus nqi ntawm qhov system.
Tab sis los ntawm engineering thiab O&M foundations, qee qhov teeb meem cuam tshuam feem ntau pib nrog cov khoom tsawg tshaj plaws.
Cov Cheebtsam me, Ntev -Lub Sijhawm Risk
PV cables thiab connectors ua haujlwm sab nraum zoov tau ntau xyoo. Lawv ntsib UV raug, qhov kub thiab txias hloov pauv, noo noo, plua plav, kev co, thiab kev ntxhov siab txhua yam.
Ib qho kev sib txuas yuav zoo li qub thaum lub sijhawm ua haujlwm, tab sis tsis zoo crimping, tsis tiav kev ntxig, cable txav, lossis cov khoom sib txuas tsis sib xws tuaj yeem ua rau muaj kev sib cuag. Kev ua haujlwm siab dua ua rau cov cua sov, thiab cov cua sov tuaj yeem ua kom muaj kev laus ntawm cov khoom sib txuas thiab cov rwb thaiv tsev cable.
Nyob rau tib lub sijhawm, qhov no tuaj yeem ua rau lub zog poob, overheating, connector deformation, txoj hlua tsis ua haujlwm, lossis txawm tias hluav taws xob arcing hauv qhov xwm txheej hnyav.
Ib Qhov Teeb Meem Ntawm Qhov Chaw
Ib qho xwm txheej yog sib xyaw lossis tsis raug sib txuam sib txuas.
Thaum lub sij hawm tsim kho, zoo sib xws - saib cov khoom sib txuas los ntawm cov khoom sib txawv lossis cov neeg muag khoom siv ua ke. Lub kaw lus yuav dhau qhov kev sim thawj zaug thiab ua haujlwm li qub thaum xub thawj.
Tom qab ntawd, pab pawg O&M tuaj yeem pom ib txoj hlua tsis zoo. Kev tshuaj xyuas cov cua kub tuaj yeem nthuav tawm qhov sib txuas kub, qee zaum nrog cov xim tsis zoo, cov vaj tsev muag muag, lossis pom kev deformation.
Qhov ua rau feem ntau tsis yog ib qho teeb meem. Nws tuaj yeem suav nrog:
Mixed connector hom uas tsis tau txheeb xyuas tias tau tshaj
Cov cuab yeej crimping tsis raug lossis crimping qhov ntev
Tsis tiav connector locking
Kev them nyiaj yug tsis zoo ua rau lub sijhawm ntev - rub lub zog
Moisture ingress tom qab rov raug huab cua
Cov khoom sib txuas tau nruab rau hauv qhov nro lossis so ntawm cov npoo ntse
Kev kho yog tsis tshua muaj txwv rau kev hloov ib qho txuas. Tus tswv yuav xav tau qhov chaw tsis raug, kaw kev sib koom ua haujlwm, hloov chaw ua haujlwm, rov kuaj dua, thiab ntau lawm- kev ntsuas poob.
Vim li cas EPC Teams Yuav Tsum Tau Saib Xyuas
NREL cov kev tshawb fawb tau txheeb xyuas cov kev sib txuas tsis ua haujlwm raws li qhov muaj txiaj ntsig kev ntseeg siab hauv PV systems. Field-ntsuas cov khoom txuas tuaj yeem ua rau muaj kev cuam tshuam ntau dua li lub Hoobkas- ntsia module connectors, tshwj xeeb tshaj yog thaum kev teeb tsa zoo thiab kev sib raug zoo tsis raug tswj xyuas kom raug.
Qhov teeb meem tseem ceeb yog qhov yooj yim:
Zoo sib xws - saib connectors tsis yog ib txwm sib xws.
Mechanical haum tsis lav qhov ruaj khov hluav taws xob tiv tauj, sealing kev ua tau zoo, los yog ntev - kev cia siab rau lub sij hawm. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv kev lag luam loj thiab kev siv hluav taws xob - cov phiaj xwm nplai, qhov twg ib qho kev sib txuas tsis muaj zog tuaj yeem nyuaj los txheeb xyuas ua ntej nws cuam tshuam rau txoj hlua kev ua haujlwm.
Common Engineering Pain Points
Connector Compatibility
Cov hom khoom sib txawv lossis cov qauv sib txawv yuav zoo ib yam tab sis siv cov qauv sib txuas sib txawv, cov qauv xauv, lossis qhov sib khi. Kev sib xyaw lawv yam tsis muaj kev pov thawj tuaj yeem tsim qhov kev pheej hmoo ntawm kev ntseeg siab zais cia.
Crimping Zoo
Cov crimping tsis zoo yog qhov nyuaj los kuaj xyuas tom qab kev teeb tsa. Qhov ntev ntawm strip ntev, puas strands, tsis raug tuag poob lawm, los yog tsis txaus crimp siab tuaj yeem ua rau tsis kam mus rau lub sijhawm.
Kev them nyiaj yug Cable thiab Routing
Connectors yuav tsum tsis txhob nqa hnyav cable. Hanging connectors, ntse khoov, tsis zoo routing, thiab cua zog tuaj yeem ua rau muaj kev ntxhov siab tsis tu ncua ntawm kev sib txuas.
Kev xaiv Cable Tshaj Loj
Tus neeg xyuas pib qhov loj me yog qhov tseem ceeb, tab sis nws tsis yog qhov tseem ceeb xwb. Lub cable yuav tsum sib phim qhov system voltage, kub tej yam kev mob, UV raug, installation txoj kev, thiab project qauv.
Cov kauj ruam tswv yim rau EPC cov neeg cog lus
Ua ntej kev yuav khoom:
Paub meej qhov tseeb connector tsev neeg thiab pom zoo mating configuration.
Xav tau daim ntawv pov thawj, cov ntaub ntawv technical, thiab batch traceability.
Tsis pom zoo hloov pauv yam tsis muaj kev tshuaj xyuas engineering.
Thaum lub sij hawm installation:
Siv cov cuab yeej crimping tshwj xeeb thiab tuag.
Xyuas strip ntev, crimp zoo, thiab xauv txoj hauj lwm.
Ua cov qauv rub tawm thiab kuaj pom.
Txhawb nqa cables kom zoo thiab tsis txhob raug tshem tawm cov khoom sib txuas.
Ua ntej xa khoom:
Ua kom tiav txoj hlua - qib ntsuas hluav taws xob.
Siv thermal tshuaj xyuas qhov ua tau zoo.
Cov ntaub ntawv cable thiab connector batch ntaub ntawv rau yav tom ntej tu.
suav nrog DC- kev txheeb xyuas sab hauv O&M txoj kev npaj.
Kev ntseeg tau ua rau hauv cov ntsiab lus
Lub siab -kev ua tau zoo module thiab lub inverter txhim khu kev qha tsis tuaj yeem them nyiaj rau DC tsis zoo - sab kev sib txuas.
Rau EPC cov neeg cog lus, cables thiab connectors yuav tsum tsis txhob raug kho raws li qis - cov khoom tseem ceeb. Lawv yog ib qho tseem ceeb ntawm txoj kev fais fab thiab yuav tsum tau txais tib yam li cov khoom siv loj.
Ntawm SINELINK, peb muab PV DC cables, PV connectors, thiab lwm yam sib npaug - ntawm -cov khoom siv rau cov ntawv thov. Peb tsom mus rau cov kev qhia tshwj xeeb, kev ua tau zoo, thiab kev txhawb nqa kev teeb tsa los pab txhim kho lub sijhawm ntev - PV system kev ntseeg tau.
