Cov cuab yeej tiv thaiv hluav taws xob hnub ci uas siv tau rau kev tiv thaiv lub hnub ci lossis lub hnub ci vaj huam sib luag inverter
Cov Khoom Siv Tiv Thaiv Surge (SPDs) yog qhov tseem ceeb rau kev tiv thaiv cov inverters photovoltaic hnub ci (PV) los ntawm kev nce hluav taws xob thiab spikes, tshwj xeeb tshaj yog cov uas tshwm sim los ntawm xob laim. Hauv cov cheeb tsam uas muaj kev ua haujlwm xob laim ntau, cov kab ke PV tsis muaj kev tiv thaiv tuaj yeem ntsib kev puas tsuaj ntau zaus thiab hnyav, ua rau cov nqi kho loj heev, lub sijhawm tsis ua haujlwm ntev, thiab poob nyiaj tau los. SPDs ntsia kom raug yog qhov tseem ceeb rau kev txo qis qhov cuam tshuam ntawm xob laim thiab tiv thaiv cov khoom rhiab heev ntawm PV systems, suav nrog AC / DC inverters, cov khoom siv saib xyuas, thiab PV arrays. Los ntawm kev nqis peev rau kev tiv thaiv surge zoo, koj tuaj yeem ua kom ntseeg tau tias koj lub zog hnub ci muaj sia nyob ntev thiab ntseeg tau.
Yuav ua li cas xaiv cov cuab yeej tiv thaiv kev kub ntxhov kom raug rau koj daim ntawv thov tshwj xeeb?
Kev xaiv cov khoom siv tiv thaiv hluav taws xob (SPD) uas zoo rau koj daim ntawv thov yog qhov tseem ceeb heev. Pib los ntawm kev txheeb xyuas hom SPD uas koj xav tau. Cov khoom siv T1 ua haujlwm zoo tshaj plaws hauv cov chaw muaj kev pheej hmoo siab, xws li thaj chaw uas muaj hluav taws xob ncaj qha. Cov no feem ntau tshwm sim hauv cov tsev lag luam lossis cov tshuab photovoltaic. Cov khoom siv T2 siv sab hauv tsev los tswj cov hluav taws xob tsis ncaj qha, thaum cov khoom siv T3 muab kev tiv thaiv ntxiv rau cov khoom siv hluav taws xob rhiab heev.
Tshawb xyuas qhov ntsuas hluav taws xob kom paub tseeb tias nws phim koj lub cev. Rau cov tshuab DC xws li photovoltaic teeb tsa, kev xaiv lub cuab yeej nrog lub zog hluav taws xob raug yog qhov tseem ceeb. Koj kuj tseem yuav xav kom paub tseeb tias lub peev xwm tso tawm tuaj yeem tswj tau cov qib siab uas xav tau. Hauv thaj chaw muaj kev pheej hmoo siab, lub peev xwm siab dua yog qhov tseem ceeb. Thiab tsis txhob hnov qab txog lub sijhawm teb - kev teb sai yog qhov tseem ceeb rau kev tiv thaiv cov khoom siv rhiab heev los ntawm kev nce siab ntawm hluav taws xob.
Xav txog qhov chaw uas SPD yuav raug teeb tsa. Yog tias nws raug rau qhov xwm txheej hnyav, xaiv cov qauv uas tiv taus huab cua lossis hluav taws kub. Rau cov ntawv thov tseem ceeb, SPDs nrog kev saib xyuas deb muab cov kev hloov kho tshiab ntawm lub sijhawm tiag tiag, pab nrog kev saib xyuas thiab hloov pauv. Thaum kawg, xyuas kom tseeb tias SPD ua tau raws li cov qauv kev lag luam xws li IEC 61643 thiab nqa cov ntawv pov thawj xws li ISO lossis CE.
Peb lub Hoobkas cov SPDs ua tau raws li txhua yam tseem ceeb uas tsim nyog rau kev tiv thaiv txhim khu kev qha. Los ntawm kev xaiv peb cov khoom siv tiv thaiv kev kub ntxhov, koj yuav ua kom muaj kev tiv thaiv zoo tshaj plaws thiab kev ntseeg siab mus sij hawm ntev rau koj cov khoom siv.
Kev muaj peev xwm saib xyuas chaw deb yuav ua li cas thiaj txhim kho kev tiv thaiv hluav taws xob?
Qhov no tso cai rau cov teeb meem uas yuav tshwm sim tau thaum ntxov, ua rau muaj kev saib xyuas ua ntej ua ntej muaj kev puas tsuaj. Los ntawm kev txheeb xyuas cov teeb meem ua ntej, cov lag luam tuaj yeem teem sijhawm tshuaj xyuas lossis hloov pauv raws sijhawm, txo qhov kev pheej hmoo ntawm kev siv nyiaj ntau dhau lossis kev puas tsuaj rau cov khoom siv. Cov lus ceeb toom tam sim ntawd kuj txo qhov kev cuam tshuam ntawm lub kaw lus, tshwj xeeb tshaj yog nyob rau hauv cov khoom siv tseem ceeb xws li cov tshuab photovoltaic lossis cov chaw ua haujlwm, qhov twg kev cuam tshuam hluav taws xob tuaj yeem ua rau muaj kev poob nyiaj txiag loj.
Ntxiv mus, kev saib xyuas nyob deb txo cov nqi ua haujlwm thiab kev saib xyuas los ntawm kev tshem tawm cov kev kuaj xyuas tsis tsim nyog, thaum ua kom cov khoom siv tiv thaiv hluav taws xob ua haujlwm zoo tshaj plaws. Rau cov kev teeb tsa loj dua, kev tswj hwm ntau yam khoom siv thoob plaws ntau qhov chaw sib txawv ua rau cov txheej txheem yooj yim dua, ua kom ntseeg tau tias muaj kev ntseeg siab thiab teb sai rau cov teeb meem.
