Yuav ua li cas photovoltaic inverters tiv taus kub kub tshaj 40 ° C?

Lub caij ntuj sov no, ntau thaj chaw thoob plaws Suav teb tau tshaj tawm liab ceeb toom rau huab cua sov, nrog rau nruab hnub kub hauv ntau lub nroog nce mus txog 40 ° C, tsim cov xwm txheej nco txog 'qhov cub hluav taws kub'. Nyob rau hauv cov xwm txheej zoo li no, txawm tias tib neeg tawm tsam tawm hauv qhov chaw cua txias, thaum cov khoom siv hluav taws xob photovoltaic ua haujlwm sab nraum zoov ntsib teeb meem loj. Tshwj xeeb tshaj yog hais txog yog 'core hlwb' ntawm photovoltaic systems - lub inverter. Yuav ua li cas cov cuab yeej no tiv taus cua sov?

Yuav ua li cas puas kub siab rau inverter Cheebtsam?

Photovoltaic inverters yog cov khoom siv sib xyaw ua ke nrog ntau cov khoom siv hluav taws xob siab, nrog rau cov khoom tseem ceeb xws li inductors, capacitors, thiab lub zog semiconductor modules. Kev kub siab tsis tsuas yog cuam tshuam kev ua haujlwm ntawm cov khoom siv no, tab sis kuj ua rau lawv cov laus, ua rau lawv lub neej luv, thiab tuaj yeem ua rau cov khoom siv tsis ua haujlwm.

Inductors: Nyob rau hauv ib puag ncig kub kub, inductors nkag saturate, txo lawv cov saturated inductance. Qhov no ua rau muaj qhov nce siab tam sim no, ua rau muaj kev pheej hmoo ntawm overcurrent thiab muaj peev xwm hlawv cov khoom siv hluav taws xob.

Capacitor: Aluminium electrolytic capacitor, tshwj xeeb, yog qhov kub-rhiab heev. Cov ntaub ntawv qhia tau hais tias rau txhua txhua 10 ° C nce hauv qhov kub thiab txias, lawv lub neej yog halved. Txawm hais tias zaj duab xis capacitors qhia tau hais tias muaj kev kub ntxhov zoo dua, cov nqi thiab qhov loj me txwv lawv txoj kev siv dav dav.

Lub zog Modules: Rau cov chips fais fab xws li IGBTs thiab MOSFETs, 'kev sib tshuam kub' ua haujlwm raws li qhov tseem ceeb ntawm kev ua haujlwm. Thaum lub nti kub tshaj nws qhov kev txwv, 'thermal breakdown' tshwm sim, ncaj qha ua rau inverter kaw.

Thermal Design: Inverter Chaw tsim tshuaj paus lub zais riam phom

Txhawm rau kom muaj kev ua haujlwm ruaj khov nyob rau hauv qhov chaw kub kub, photovoltaic inverters siv cov txheej txheem thermal tswj xyuas kom zoo. Lub hauv paus ntsiab lus tseem ceeb yog tswj hwm txhua yam khoom nyob rau hauv nws qhov ntsuas kub tau.

Cov txheej txheem kev tswj hwm thermal feem ntau suav nrog:

Cua txias systems: Nruab nrog cov kiv cua ntse hloov pauv ceev uas tau hloov pauv huab cua raws li qhov kub thiab txias hloov pauv, ntsuas qhov txias txias nrog lub zog ua haujlwm thiab txo suab nrov.

Optimization ntawm lub rhaub dej kub: Txhim khu kev sib pauv thermal efficiency los ntawm kev ua kom sov lub dab dej ntawm thaj chaw, kev kho kom zoo nkauj (xws li, serrated fin designs), thiab siv cov khoom siv thermal-conductivity.

Integrated chassis tsim: Ntau zuj zus, hwm inverters siv aluminium alloy tuag-casting rau fuse tshav kub dissipation qauv nrog lub chassis. Ua ke nrog cov thermal silicone gel thiab cov hluav taws kub sib kis, qhov no ua kom yooj yim tshem tawm cov cua sov sai.

Piv txwv li, qee lub npe 'siab kub siab ntev' inverters feature dual-insurance txias tshuab suav nrog thaj tsam loj hauv qab fins thiab cov kiv cua ntse. Qhov no tsis tsuas yog txhim kho adaptability nyob rau hauv huab ib puag ncig tab sis kuj ua kom lub cev ruaj khov mus ntev.

Inverter Thaum tshav kub kub tiv thaiv cov tswv yim: ua ntej installation thiab tu

Tshaj li qhov ua tau zoo ntawm qhov kub thiab txias, qhov zoo tshaj plaws kev teeb tsa ib puag ncig thiab kev saib xyuas txhua hnub yog qhov tseem ceeb sib npaug.

Qhov Chaw Xaiv Qhov Teeb Meem: Txhim kho inverters nyob rau hauv qhov chaw zoo-ventilated sheltered los ntawm lub hnub ncaj qha. Rau kev teeb tsa sab nraum zoov, xav txog kev ntxiv sunshades los txo qhov raug tshav ntuj thiab los nag. Thaum mounting ntau inverters ib sab-los-sab, xyuas kom meej qhov chaw txaus los pab kom cov cua sov dissipation zoo.

Kev ntxuav tu tsis tu ncua yog qhov tseem ceeb: Nyob rau hauv ib puag ncig kub, plua plav yooj yim accumulates ntawm cov dab dej kub thiab cov kiv cua, cuam tshuam kev ua kom txias. Nws raug nquahu kom kuaj xyuas qhov cua txias tsawg kawg ib hlis rau cov plua plav lossis cov khoom thaiv txawv teb chaws, ua haujlwm tu kom sai thaum tsim nyog.

Saib xyuas cov xwm txheej ua haujlwm: Tsis tu ncua xyuas lub inverter zaub, LED qhov taw qhia, thiab cov chaw taws teeb saib xyuas kev ceeb toom xws li 'kev ceeb toom kub dhau' lossis ' kiv cua malfunctions'. Yog tias muaj qhov tsis txaus ntseeg tshwm sim, tshawb xyuas tam sim ntawd thiab hu rau tus kws tshaj lij kev txhawb nqa tom qab muag yog tias xav tau.

Kev xav zaum kawg: Kev kub siab tsis yog ib qho kev ua ntawm Vajtswv, tab sis kev sim litmus rau kev tsim qauv

Raws li lub caij ntuj sov heatwaves intensified txhua xyoo nyob rau hauv Tuam Tshoj, ib tug inverter lub thermal resilience tau dhau los ua ib tug tseem ceeb benchmark rau cov khoom ntseeg tau. Rau PV cov tswv cog thiab O&M cov neeg ua haujlwm, xaiv cov khoom siv hluav taws xob zoo nrog kev tswj xyuas thermal zoo yog qhov tseem ceeb los ua kom muaj txiaj ntsig zoo thiab ruaj khov.

Cov kub kub tsis yog yeeb ncuab-tsis npaj txhij. Cia peb tiv thaiv peb cov PV inverters nrog 'heatwave shield' kom tiv taus lub caij ntuj sov lub scorching nthwv dej, kom ntseeg tau tias txhua kilowatt-teev ntawm lub zog ntsuab raug xa tuaj.
