Nrog txoj kev loj hlob sai ntawm kev lag luam hluav taws xob tshiab, kev tsim hluav taws xob photovoltaic tau siv ntau thiab ntau dua. Raws li ib feem tseem ceeb ntawm photovoltaic lub zog tsim hluav taws xob, photovoltaic inverters yog ua nyob rau hauv ib puag ncig sab nraum zoov, thiab lawv raug rau qhov hnyav hnyav thiab hnyav hnyav.
Rau sab nraum zoov PV inverters, tus qauv tsim yuav tsum ua raws li tus qauv IP65. Tsuas yog los ntawm kev ua tiav tus qauv no tuaj yeem ua rau peb cov inverters ua haujlwm nyab xeeb thiab ua haujlwm tau zoo. Qhov ntsuas IP yog rau qib kev tiv thaiv ntawm cov khoom txawv teb chaws hauv cov khoom siv hluav taws xob. Lub hauv paus yog lub International Electrotechnical Commission tus qauv IEC 60529. Cov qauv no kuj tau txais raws li US lub teb chaws tus qauv nyob rau hauv 2004. Peb feem ntau hais tias IP65 qib, IP yog cov ntawv luv rau Ingress Protection, ntawm 6 yog qib plua plav, (6 : tag nrho tiv thaiv plua plav los ntawm kev nkag); 5 yog qib dej tsis muaj dej, (5: dej da dej cov khoom tsis muaj kev puas tsuaj).
Yuav kom ua tiav cov kev tsim qauv saum toj no, cov qauv tsim qauv ntawm photovoltaic inverters yog nruj heev thiab ceev faj. Qhov no kuj yog ib qho teeb meem uas yooj yim heev los ua teeb meem hauv daim ntawv thov teb. Yog li cas peb tsim cov khoom tsim nyog inverter?
Tam sim no, muaj ob hom kev tiv thaiv feem ntau siv hauv kev tiv thaiv ntawm lub hau sab sauv thiab lub thawv ntawm lub inverter hauv kev lag luam. Ib qho yog siv lub nplhaib silicone waterproof. Hom silicone waterproof nplhaib no feem ntau 2 hli tuab thiab dhau los ntawm lub hau thiab lub thawv. Nias kom ua tiav cov nyhuv dej tsis zoo thiab plua plav. Hom kev tiv thaiv no yog txwv los ntawm tus nqi ntawm deformation thiab hardness ntawm silicone roj hmab waterproof nplhaib, thiab tsuas yog haum rau me me inverter thawv ntawm 1-2 KW. Cov txee loj muaj ntau qhov kev phom sij zais hauv lawv cov txiaj ntsig tiv thaiv.
Daim duab hauv qab no qhia tau hais tias:
Lwm qhov yog kev tiv thaiv los ntawm German Lanpu (RAMPF) polyurethane styrofoam, uas tau txais cov lej tswj kev ua npuas ncauj molding thiab ncaj qha rau cov khoom siv xws li lub hau npog, thiab nws cov deformation tuaj yeem ncav cuag 50%. Saum toj no, nws yog tshwj xeeb tshaj yog haum rau kev tiv thaiv tsim ntawm peb nruab nrab thiab loj inverters.
Daim duab hauv qab no qhia tau hais tias:
Nyob rau tib lub sijhawm, qhov tseem ceeb tshaj plaws, hauv kev tsim cov qauv, txhawm rau ua kom lub zog muaj zog tsis muaj zog, lub qhov dej tsis sib haum yuav tsum tau tsim los ntawm sab saum toj npog ntawm photovoltaic inverter chassis thiab lub thawv kom ntseeg tau tias txawm tias dej pos huab. hla dhau lub hau npog thiab lub thawv. Nyob rau hauv lub inverter nruab nrab ntawm lub cev, tseem yuav coj los ntawm lub tank dej sab nraum cov dej tee dej, thiab tsis txhob nkag mus rau hauv lub thawv.
Nyob rau hauv xyoo tas los no, muaj kev sib tw hnyav hauv kev lag luam photovoltaic. Qee lub tuam txhab inverter tau ua qee qhov yooj yim thiab hloov pauv los ntawm kev tiv thaiv tsim thiab siv cov khoom siv txhawm rau tswj cov nqi. Piv txwv li, daim duab hauv qab no qhia tau hais tias:
Sab laug yog tsim kom txo nqi. Lub thawv lub cev yog khoov, thiab tus nqi yog tswj los ntawm cov ntaub ntawv hlau thiab cov txheej txheem. Piv nrog rau lub thawv peb-folding ntawm sab xis, muaj qhov pom tseeb tsawg dua qhov sib txawv ntawm lub thawv. Lub zog ntawm lub cev kuj tseem qis dua, thiab cov qauv tsim no coj lub peev xwm zoo rau kev siv hauv cov dej tsis zoo ntawm lub inverter.
Tsis tas li ntawd, vim tias lub thawv inverter tsim ua tiav qib kev tiv thaiv IP65, thiab qhov kub thiab txias ntawm lub inverter yuav nce ntxiv thaum lub sijhawm ua haujlwm, qhov sib txawv ntawm qhov kub siab los ntawm qhov kub thiab txias thiab lwm yam kev hloov pauv ib puag ncig yuav ua rau cov dej nkag mus thiab ua rau muaj kev puas tsuaj rau hluav taws xob. cov khoom. Txhawm rau zam qhov teeb meem no, peb feem ntau nruab ib lub tshuab nqus dej tsis muaj pa rau ntawm lub thawv inverter. Lub valve tsis muaj dej thiab ua pa tuaj yeem ua kom sib npaug ntawm lub siab thiab txo qhov tshwm sim ntawm condensation hauv cov khoom kaw, thaum thaiv kev nkag ntawm cov plua plav thiab kua. Txhawm rau txhim kho kev nyab xeeb, kev ntseeg siab thiab kev pabcuam lub neej ntawm cov khoom siv inverter.
Yog li ntawd, peb tuaj yeem pom tias qhov tsim nyog photovoltaic inverter qauv tsim yuav tsum tau ua tib zoo thiab nruj tsim thiab xaiv tsis hais tus qauv tsim ntawm lub chassis lossis cov khoom siv. Txwv tsis pub, nws yog blindly txo los tswj cov nqi. Cov kev tsim qauv tsuas tuaj yeem nqa cov kev phom sij zoo rau kev ua haujlwm ruaj khov mus ntev ntawm photovoltaic inverters.
