Lub quarter kawg ntawm kev xa khoom ntawm 48 hnub ci inverter skids tawm ntawm peb lub khw hauv Qingdao, mus rau 90 MW kev siv hluav taws xob- nplai PV cog hauv cheeb tsam New South Wales. Thawj cov qauv tuaj txog rau lub lis piam tom qab - tsis pom kev puas tsuaj, tsis muaj txheej txheej tsis ua hauj lwm, txhua qhov skid squared mus rau hauv 2 hli ntawm daim duab. Cov khoom xa tuaj dhau los ntawm tus neeg yuav khoom ua ntej yog txawv. Kaum ob ntawm plaub caug- yim units tau twisted thav duab, tawg bolt pob qij txha, ib lub ces kaum tawg los ntawm. Kaum ob skids. Rau lub lis piam. Ib tug txheem hiav txwv voyage.
Kev kho tsis yog kab txawv - cov khoom sib pauv: aluminium extrusion los ua kub -dip galvanizedsheet hlau fabrication- Q355B welded ncej, AS/NZS 5131 SP2 tolerances, AS/NZS 4680 HDG txheej - ntxiv rau ib qho kev hloov pauv. Cov neeg muag khoom sib txawv ntawm cov neeg yuav khoom hu rau tib qhovsheet hlau fabricationlos yogstructural steel fabrication. Peb hu nws los ntawm dab tsi ciaj sia lub nkoj. Hnyav ntawm daim ntawv, pheej yig dua ntawm cov khoom kab, deb dua pheej yig dua thaum nws mus txog lub ncoo.
Tus neeg yuav khoom thiab siv Case
Tus neeg yuav khoom yog Australian EPC tus neeg cog lus tsim khoom siv hluav taws xob- nplai PV nroj tsuag. Txhua qhov skid mounts 2.5 MW central inverter ntxiv rau DC combiner txee - txog 1.6 tonnes ntawm cov khoom tuag. Rau kev siv hluav taws xob- nplai PV skids rau rau - lub lim tiam dej hiav txwv, txoj kev hla yuav tsum ua plaub yam ib zaug:
● Nqa inverter tuag load thiab cua loads ntawm lub ncoo
● Tiv thaiv rau -lub lim tiam dej hiav txwv- voyage vibration los ntawm chaw nres nkoj tauj
●Tuav IP65 sealing ntawm cable caj pas nkag tom qab kev mus ncig
● Zaum ca ntawm lub pob zeb uas muaj shim kam rau siab tshaj 3 hli
Qhov kawg taw tes yog qhov twg aluminium ntsiag to ua tsis tiav.
Yog vim li cas Aluminium Ncej ua tsis tiav ntawm Hiav Txwv
Aluminium extrusion yog ib qho kev xaiv raug cai rau hauv tsev lossis luv luv- daim ntawv thov thauj khoom - lub teeb, xeb- pub dawb, zam txim rau tus nqi tsev. Hom kev ua tsis tiav ntawm no yog qhov tshwj xeeb rau rau -lub lim tiam dej hiav txwv thauj khoom nrog rov qab qis dua - zaus vibration.
Kev vibration-loosing.Bolt- ua ke aluminium thav duab muaj pua pua ntawm cov hlua khi. Rau lub lim tiam ntawm qis- zaus vibration (lub cav sib haum xeeb, sloshing, chaw nres nkoj tuav) taug kev bolts rov qab. Ncej dhau lub thawv kos, ces twist thaum kawg ceg.
Thermal mismatch.Inverters khiav sov. Cov pa roj carbon hlau nthuav dav tsawg (~ 11.7 µm / m· degree); 6061-T6 txhuas txav roughly ob zaug ntau npaum li ib℃(~ 23.6 µm / m·℃). Tom qab ib xyoos ntawm Queensland ncoo, qhov sib koom ua ke ntawm lub caj pas cable.
Tsis muaj qhov sib npaug HDG.Aluminium tsis teb rau tib txheej txheej. Dissimilar-hloov sib cuag ntawm bolt interfaces corroded nyob rau hauv ob peb lub voj voog monsoon.
DFM Kauj Ruam Feem Ntau Cov Neeg Muag Khoom Hla
Qhov laj thawj loj tshaj plaws uas peb cov thawj pawg tau tawm mus yam tsis muaj kev rov ua haujlwm yog ib qho -hnub thuam- txog tus neeg xa khoom ua ntej tsis tau khiav.
Ua ntej tooling, peb taug kev tus neeg yuav khoom los ntawm a1: 5 scale mock-txog ntawm txhua txoj kab hluav taws xob nkag mus- gland spacing colliding with the inverter fan cowling, gland orientation pointing into the rain hood, one bolt vajvoog 4 mm too close to a structural rib. Tus nqi: ib hnub ntawm peb sab, xoom ntawm tus neeg yuav khoom. Hauv kev khiav ua ntej, peb qhov yuam kev tshwm sim li14 ntawm 48 skids xav tau resealing ntawm qhov chaw- rau lub lim tiam ntawm cov neeg ua haujlwm teev nyob rau ntawm Queensland ncoo thaum lub caij ntuj sov. Peb qhov kev khiav haujlwm tsis muaj qhov tshwm sim rov ua dua tshiab. Yog tias koj tus neeg muag khoom tam sim no muab koj daim duab kos thiab hnub xa khoom yam tsis muaj kev thuam -up, nug yog vim li cas.
