Surge Protective Devices yog cov cuab yeej tiv thaiv tseem ceeb rau lub hnub ci hluav taws xob, daws qhov teeb meem tshwj xeeb thiab qhov hluav taws xob overvoltage ntawm photovoltaic (PV) hluav taws xob tsim teeb meem thiab ua kom lub sij hawm ntev - kev nyab xeeb thiab ruaj khov ntawm cov chaw nres tsheb hnub ci. Qhov tsim nyog ntawm SPD daim ntawv thov hauv lub hnub ci hluav taws xob tau cuam tshuam rau ntau yam.
Ua ntej, lub hnub ci fais fab chaw nres tsheb muaj kev pheej hmoo hluav taws xob ntau heev. Feem ntau cov tshuab hluav taws xob photovoltaic tau tsim nyob rau hauv qhov chaw qhib sab nraum zoov xws li thaj chaw roob, cov suab puam, thiab thaj chaw qhib nyob deb nroog uas tsis muaj chaw nyob siab. Hnub ci vaj huam sib luag arrays, sab nraum zoov combiner lub thawv, thiab tej thaj chaw deb fais fab kis kab mob yog heev yooj yim mus rau direct thiab indirect hluav taws xob ntaus, uas tsim loj heev transient overvoltages. Yog tsis muaj kev tiv thaiv SPD, xob laim surges yuav ua rau puas lub hnub ci vaj huam sib luag, inverters, thiab cov khoom siv hluav taws xob.
Thib ob, lub hnub ci hluav taws xob hluav taws xob raug kev txom nyem los ntawm kev hloov pauv sab hauv ntau zaus. PV systems muaj cov cuab yeej tseem ceeb xws li photovoltaic inverters, DC cov thawv sib txuas, thiab kab hluav taws xob- cov khoom siv hluav taws xob sib txuas. Ntau zaus DC-AC hloov dua siab tshiab, kab sib txuas thiab kev sib txuas, thiab lub zog thauj khoom hloov pauv yuav ua rau lub sijhawm hloov pauv hloov pauv thiab qhov hluav taws xob sib txawv, uas maj mam ua rau cov khoom siv rwb thaiv tsev thiab ua kom cov khoom siv aging tsis muaj kev cuam tshuam zoo.
Thib peb, PV cov cuab yeej muaj qhov ua siab ntev overvoltage thiab cov nqi kho mob siab. Hnub ci inverters, tus nqi tswj, thiab daim phiaj ntse- cov khoom siv sib txuas yog cov khoom siv hluav taws xob muaj zog nrog cov chips rhiab thiab circuits. Txawm tias microsecond-theem overvoltage surges tuaj yeem ua rau Circuit Court tawg, cov khoom siv hluav taws xob, thiab kev sib txuas hauv kab sib chaws. Qhov loj - teeb tsa ntawm lub hnub ci vaj huam sib luag thiab kev faib chaw nres tsheb hauv chaw nres tsheb ua rau cov nqi kho mob siab thiab lub sijhawm poob qis thaum cov khoom puas lawm.
Plaub, ntev -kab kis tau tus mob ua kom muaj kev phom sij txaus ntshai. Lub hnub ci fais fab chaw nres tsheb feem ntau siv ntev -kab kis tau tus mob kom xa hluav taws xob mus rau daim phiaj. Cov kab hluav taws xob sab nraum zoov ntev tau ua rau muaj kev cuam tshuam ntau dhau nyob rau hauv huab cua thunderstorm thiab electromagnetic cuam tshuam, thiab surge zog accumulates raws kab, ua rau muaj kev hem thawj rau cov khoom siv hluav taws xob. SPDs tuaj yeem clamp overvoltages thiab hloov pauv lub zog ntawm cov pob tseem ceeb los thaiv kev sib kis.
Thib tsib, SPDs txhim kho lub zog tsim hluav taws xob thiab kev ruaj ntseg system. Surge-vim voltage hloov pauv yuav ua rau nquag pib thiab kaw ntawm inverters thiab tsis muaj zog tso zis, txo cov hnub ci tsim hluav taws xob efficiency. Txhim kho SPDs stabilizes system voltage, txo cov cuab yeej tsis ua hauj lwm tus nqi, xyuas kom tsis tu ncua daim phiaj- txuas hluav taws xob, thiab txhim kho cov txiaj ntsig kev lag luam ntawm cov chaw nres tsheb hnub ci.
