Nrog rau kev txhim kho sai ntawm kev lag luam hluav taws xob tshiab, photovoltaic lub zog yog ntau thiab ntau dav siv. Raws li ib qho tseem ceeb ntawm photovoltaic lub zog inverters tau ua haujlwm nyob rau hauv ib puag ncig sab nraud, thiab lawv yog kev ntsuam xyuas hnyav heev.
Rau sab nraum zoov PV inverters, cov qauv tsim yuav tsum ua kom tau raws li tus qauv IP65. Tsuas yog los ntawm kev ncav cuag tus qauv no tuaj yeem ua rau peb lub inverers ua haujlwm kom nyab xeeb thiab muaj txiaj ntsig. Tus IP ntsuas yog rau qib kev tiv thaiv ntawm cov ntaub ntawv txawv teb chaws hauv cov khoom siv hluav taws xob. Qhov chaw yog International Electrotechnical Commission tus qauv IEC 60529. Cov lus luv no, IP yog theem hauv xyoo 2004 yog qhov 6 yog cov hmoov av 5 yog theem waterproof, (5: dej da dej yam khoom uas tsis muaj kev puas tsuaj).
Txhawm rau kom ua tiav cov qauv tsim qauv saum toj no, cov qauv tsim qauv yuav tsum tau ua cov photovoltaic inverters yog nruj heev thiab muaj kev ruaj ntseg. Qhov no tseem yog qhov teeb meem uas yooj yim heev rau kev tsim teeb meem hauv daim teb daim ntawv thov. Yog li peb yuav tsim cov khoom lag luam inverter tsim nyog li cas?
Tam sim no, muaj ob hom kev tiv thaiv feem ntau siv nyob rau hauv kev tiv thaiv nruab nrab ntawm sab saud thiab lub thawv inverter hauv kev lag luam. Ib qho yog kev siv ntawm lub nplhaib dej silicone dej. Hom ntawm lub nplhaib hluav taws xob Silicone Silicone Silicone Nias kom ua tiav cov nyhuv waterproof thiab hmoov av. Qhov kev tiv thaiv kev tiv thaiv no tsuas yog txwv ntawm kev deformation thiab hardness ntawm silicone roj hmab waterproof nplhaib, thiab tsuas yog tsim nyog rau cov thawv me me ntawm 1-2 kW. Cov khoom loj muaj ntau cov kev phom sij hauv lawv cov nyhuv tiv thaiv.
Daim duab hauv qab no qhia tias:
Lwm tus yog kev tiv thaiv los ntawm German Lanpu (Rampf) Polyurethane Styfoam, uas yog ncaj qha rau cov txheej txheem xws li cov npog sab saud, thiab nws deformation tuaj yeem ncav 50%. Saum toj no, nws yog qhov tshwj xeeb tshaj yog tsim nyog rau kev tiv thaiv kev tsim qauv ntawm peb cov inverers loj.
Daim duab hauv qab no qhia tias:
Nyob rau tib lub sijhawm, qhov tseem ceeb tshaj plaws, hauv kev tsim qauv ntawm tus qauv, txhawm rau txhim kho lub ntsej muag lim dej hauv lub ntsej muag thiab cov dej npau suav dhau los ntawm cov hau sab saum toj thiab lub thawv. Mus rau hauv inverter ntawm lub cev, kuj tseem yuav tau coj los ntawm cov dej tank sab nraum cov tee dej dej sab nraud, thiab tsis txhob nkag mus rau lub thawv.
Nyob rau hauv xyoo tsis ntev los no, tau muaj kev sib tw hnyav hauv kev ua lag luam photovoltaic. Qee cov tuam txhab inverter tau ua qee qhov yooj yim thiab hloov kho los ntawm kev tiv thaiv tsim thiab siv txhawm rau txhawm rau tswj cov nqi. Piv txwv li, daim duab hauv qab no qhia tau tias:
Sab laug sab yog tus nqi txo tus qauv. Lub thawv lub cev yog khoov duav, thiab tus nqi tswj tau los ntawm cov ntawv hlau khoom thiab cov txheej txheem. Piv nrog rau lub thawv peb-folding ntawm sab xis, muaj obviously tsis muaj qhov sib txawv ntawm lub thawv. Lub zog ntawm lub cev kuj yog ntau qis dua, thiab cov qauv tsim no coj muaj peev xwm zoo rau kev siv hauv dej tsis muaj dej ntawm lub inverter.
Tsis tas li ntawd, vim hais tias lub thawv inverter lub thawv tsim qauv ntawm qib, thiab qhov sib txawv ntawm kev ua haujlwm ntawm kev ua haujlwm, kev hloov pauv sab hauv thiab kev puas tsuaj hluav taws xob sib txawv. Txhawm rau kom zam dhau qhov teeb meem no, peb feem ntau nruab cov dej tsis muaj pa hluav taws xob valve ntawm lub thawv inverter. Lub waterproof thiab breathable valve tuaj yeem ua tau zoo sib npaug thiab txo cov hws hws zoo hauv cov cuab yeej sib khi, thaum thaiv cov khoom nkag ntawm hmoov av thiab kua. Txhawm rau txhim kho kev nyab xeeb, kev cia siab thiab kev pabcuam lub neej ntawm inverter cov khoom.
Yog li ntawd, peb tuaj yeem pom tias cov photovoltaic tsim nyog yuav tsum ceev faj thiab xaiv tsis raug ntawm cov qauv ntawm cov qauv chassis lossis cov ntaub ntawv siv. Txwv tsis pub, nws yog qhov muag tsis pom kev los tswj cov nqi. Cov qauv tsim nyog yuav tsum tau coj cov kev phom sij zais rau lub sijhawm ntev ruaj khov ntawm photovoltaic inverters.
