Tawm tsam keeb kwm yav dhau los ntawm kev hloov pauv tsis tu ncua ntawm lub zog tshiab lub zog tsim hluav taws xob rau kev siv hluav taws xob ntau dua thiab muaj kev ntseeg siab dua, photovoltaic inverters, raws li cov cuab yeej tseem ceeb rau DC - rau - AC hloov dua siab tshiab, tab tom hloov kho tshiab hauv lawv cov kev tswj thiab kev tiv thaiv mechanisms. Ntawm cov kev hloov kho tshiab no, photoelectric relays, raws li kev hloov pauv tsis sib cuag raws li cov qauv kev hloov pauv photoelectric, tau maj mam hloov cov khoom siv hluav taws xob ib txwm muaj, dhau los ua cov khoom tseem ceeb rau kev txhim kho kev ua haujlwm thiab kev ruaj ntseg. Nyob rau hauv cov txheej txheem no, cov khoom siv hluav taws xob sib txuas rau PV relays kuj tau ua kom zoo dua rau kev ua tau zoo dua thiab arc tsis kam ua kom tau raws li qhov ntev - cov kev xav tau ntawm kev ua haujlwm nyob rau hauv cov xwm txheej nyuaj.
Los ntawm kev pom kev, cov qauv tseem ceeb ntawm photoelectric relay muaj lub teeb -emitting unit thiab ib chav txais photosensitive. Nws txoj haujlwm tso siab rau cov nyhuv photoelectric kom ua tiav cov teeb liab cais thiab kis tau tus mob. Thaum lub teeb liab nkag mus rau lub davhlau ya nyob twg tswj, lub LED emits lub teeb liab teeb liab, uas tau txais los ntawm lub photosensitive ntaus ntawv, yog li tsav lub internal switching xeev hloov. Hom kev ua haujlwm tsis yog -txheej txheem kev sib cuag no ua rau muaj qhov hnav tsis tshua muaj qis thiab ruaj khov heev hauv siab - zaus hloov qhov xwm txheej. Lub caij no, ntawm qhov kawg tso tawm tam sim no, cov hluav taws xob sib txuas rau photovoltaic relays tseem ua haujlwm tseem ceeb hauv kev ua haujlwm, thiab lawv cov khoom siv thiab cov qauv tsim ncaj qha txiav txim siab tag nrho cov conductivity efficiency thiab thermal stability.
Nyob rau hauv photovoltaic inverter systems, hluav taws xob cais kev ua tau zoo yog qhov tseem ceeb. Vim yog qhov siab -voltage DC- AC hloov dua siab tshiab cov txheej txheem nyob rau hauv lub system, txawm tias ib tug me me rwb thaiv tsev tsis ua hauj lwm yuav muaj txim loj. Photorelays ua tiav kev sib cais ntawm kev tswj thiab kev ua tiav xaus ntawm cov teeb liab kho qhov muag, txhim kho kev nyab xeeb. Tsis tas li ntawd, kev siv siab -kev ua haujlwm hluav taws xob tiv tauj rau Hnub Ci Vaj Huam Sib Luag Relays zoo txo qis kev tiv thaiv kev tiv thaiv thiab lub zog poob raws li kev coj ua, yog li txhim kho kev ua haujlwm tag nrho.
Photorelays kuj tseem muaj txiaj ntsig zoo ntawm kev cuam tshuam kev tiv thaiv. Ib txwm siv tshuab relays raug cuam tshuam los ntawm electromagnetic cuam tshuam, thaum photorelays, nrog rau lawv cov teeb liab kis tau tus mob, tsis cuam tshuam los ntawm cov suab nrov sab nraud electromagnetic. Cov yam ntxwv no tseem ceeb tshwj xeeb tshaj yog nyob rau hauv siab - zaus hloov pauv thiab ib puag ncig electromagnetic complex. Ib txhij, optimizing cov ntaub ntawv muaj pes tsawg leeg ntawm Fixed Silver Contacts rau hnub ci zog Relays ntxiv txhim khu kev tiv thaiv kev ruaj ntseg thiab txo cov teeb meem kev sib cuag los ntawm micro- vibrations lossis kub nce.
Teb ceev yog qhov taw qhia tseem ceeb ntawm kev ua haujlwm relay. Photorelays feem ntau ua tiav cov kev hloov pauv hauv milliseconds lossis tsawg dua, zoo dua rau cov qauv siv hluav taws xob. Lawv qhov zoo yog tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej yuav tsum tau teb sai, xws li inverter tiv thaiv circuits. Nyob rau hauv cov txheej txheem no, sib piv siab -kev ua tau zoo hluav taws xob tiv tauj rau hnub ci DC Relay ua kom muaj kev ruaj khov thaum lub sij hawm siab - hloov ceev, tiv thaiv kev puas tsuaj los ntawm kev sib hloov arcing.
Hauv cov ntawv thov tshwj xeeb ntawm photovoltaic inverters, photorelays feem ntau tswj cov tswv yim / tso zis, kev tiv thaiv kab ke, thiab kev tswj hwm xwm txheej. Piv txwv li, thaum pib, lub kaw lus yuav tsum tsim kom muaj kev sib txuas hauv Circuit Court sai; photorelays tuaj yeem teb sai sai rau kev tswj cov teeb liab, ua kom muaj txiaj ntsig zoo. Nyob rau tib lub sijhawm, siv Cov Neeg Siv Nyiaj Tsaus Ntuj rau Lub Zog Tshiab PV Zog Cia HVDC Relay tuav ruaj khov kev sib cuag hauv siab -voltage DC ib puag ncig, tiv thaiv kev ua haujlwm tsis zoo vim muaj kev hloov pauv hauv kev sib cuag.
Hauv cov xwm txheej tiv thaiv overload, photorelays tuaj yeem txiav tawm sai sai thaum pom qhov txawv txav tam sim no, tiv thaiv cov khoom puas. Thaum lub sij hawm tus txheej txheem no, lub kaw lus tiv tauj yuav tsum tiv taus tam sim no siab - tam sim no surges, yog li muab siab dua xav tau ntawm arc tsis kam ntawm cov ntaub ntawv. Los ntawm kev qhia txog kev sib cuag Brazing rau PV Energy Storage DC Contactor thev naus laus zis, kev sib cuag lub zog thiab kev ua haujlwm ruaj khov tuaj yeem txhim kho tau zoo, yog li txhim kho kev tiv thaiv tag nrho.
Tsis tas li ntawd, hauv cov tshuab ntse, photorelays kuj ua lub luag haujlwm tseem ceeb hauv kev sib cais txhaum thiab kev tswj chaw taws teeb. Thaum ib feem ntawm lub kaw lus ua haujlwm tsis zoo, lub relay tuaj yeem cuam tshuam txoj kev txhaum sai, tiv thaiv kev cuam tshuam rau kev ua haujlwm tag nrho. Nyob rau hauv cov txheej txheem no, kev txhim khu kev qha Tsiv Sib cuag rau Tshiab Zog Relay tus qauv tsim pab txhim kho cov lus teb muaj peev xwm thiab kev ruaj ntseg ntawm kev ua rov ua dua.
Los ntawm txoj kev xav, daim ntawv thov ntawm photoresistors tsis tsuas yog txhim kho kev ua tau zoo thiab kev nyab xeeb ntawm photovoltaic inverters tab sis kuj tseem txo cov nqi kho. Vim lawv tsis muaj kev siv tshuab, cov cuab yeej siv tau ntev heev, txo qhov hloov zaus. Tsis tas li ntawd, kev sib koom ua ke nrog Oxidized Hluav Taws Xob Cov Hluav Taws Xob rau Hnub Ci Relay ntxiv txhim kho tag nrho cov kev ntseeg tau, ua tau raws li qhov ntev - lub sijhawm ua haujlwm.
Saib tom ntej, raws li cov tshuab hluav taws xob tshiab hloov zuj zus mus rau qib siab dua thiab cov kev tswj xyuas nyuaj dua, kev ua kom zoo dua qub ntawm photoresistors thiab hluav taws xob tiv tauj rau hnub ci hloov yuav dhau los ua cov lus qhia tseem ceeb. Los ntawm cov khoom siv tshiab, kev ua kom zoo dua qub, thiab kev txhim kho cov txheej txheem tsim khoom, cov khoom siv no yuav ua lub luag haujlwm tseem ceeb hauv siab -voltage DC, lub zog cia, thiab cov phiajcim ntse.
