Isolator hloov yog ib qho hluav taws xob high-voltage switchgear, feem ntau yog siv nyob rau hauv high-voltage circuits.Nws yog lub switchgear yam tsis muaj arc extinguishing ntaus ntawv, feem ntau yog siv los disconnect lub Circuit Court yam tsis muaj load tam sim no, cais lub hwj chim mov, thiab muaj ib tug pom tseeb disconnection point nyob rau hauv qhib lub xeev los xyuas kom meej kev nyab xeeb kev soj ntsuam thiab kho lwm yam khoom siv hluav taws xob.Nws tuaj yeem ntseeg tau dhau qhov qub thauj khoom tam sim no thiab luv luv-circuit tam sim no hauv lub xeev kaw.Vim tias nws tsis muaj qhov tshwj xeeb arc extinguishing ntaus ntawv, nws tsis tuaj yeem txiav tawm qhov tam sim no thiab luv-circuit tam sim no.Yog li ntawd, qhov kev rho tawm tuaj yeem ua haujlwm tsuas yog thaum lub tshuab hluav taws xob tau raug txiav tawm los ntawm lub tshuab hluav taws xob.Nws yog nruj me ntsis txwv tsis pub khiav lag luam nrog kev thauj khoom kom tsis txhob muaj cov khoom siv loj thiab cov xwm txheej ntawm tus kheej.Tsuas yog voltage transformers, xob laim ntes, tsis muaj load transformers nrog excitation tam sim no tsawg dua 2A, thiab tsis muaj-load circuits nrog tam sim no tsis ntau tshaj 5A tuaj yeem ua haujlwm ncaj qha nrog kev rho tawm keyboards.Hauv kev siv hluav taws xob hluav taws xob, cov hluav taws xob hluav taws xob thiab cov hluav taws xob sib cais feem ntau yog siv ua ke, thiab covCircuit Court breakersyog siv los hloov thiab txiav load (fault) tam sim no, thiab lub isolator hloov ua ib qho pom tseeb disconnection point.
CovHnub ci vaj huam sib luag dc isolator hloovyog ib qho khoom siv hluav taws xob kev nyab xeeb uas tuaj yeem cuam tshuam nws tus kheej los ntawm cov modules hauv lub hnub ci photovoltaic system.Hauv daim ntawv thov photovoltaic, PV DC isolators yog siv los txiav tawm lub hnub ci vaj huam sib luag rau kev saib xyuas, teeb tsa lossis kho.Hauv kev teeb tsa, kev saib xyuas niaj hnub thiab xwm txheej xwm txheej ceev, lub vaj huam sib luag yuav tsum tau muab cais tawm ntawm AC sab, yog li kev hloov pauv ntawm tus kheej tau muab tso rau ntawm lub vaj huam sib luag thiab cov khoom siv inverter.Hom kev hloov no yog hu ua PV DC rho tawm hloov vim nws muab DC kev rho tawm ntawm lub vaj huam sib luag photovoltaic thiab lwm qhov system.Qhov no yog qhov hloov pauv tsis muaj kev nyab xeeb, uas yuav tsum tau ua hauv txhua qhov kev tsim hluav taws xob photovoltaic raws li IEC 60364-7-712.Hnub ci vaj huam sib luag dc isolator hloov yog ib qho tseem ceeb tshaj plaws ntawm photovoltaic system kev nyab xeeb.Nws txoj kev ntseeg siab thiab kev ruaj ntseg yog cuam tshuam nrog lub zog ruaj khov thiab muaj txiaj ntsig ntawm photovoltaic system, nrog rau kev nyab xeeb thiab txhim khu kev qha ntawm photovoltaic system.Nrog rau kev nce hauv kev teeb tsa photovoltaic, lub zog tsim hluav taws xob tau nyiam ntau yam.Txawm li cas los xij, cov tub lag luam hluav taws xob tau txhawj xeeb ntau ntxiv txog cov teeb meem kev nyab xeeb, uas tau tshwm sim ntau zaus hauv photovoltaic fais fab nroj tsuag hauv xyoo tas los no.
Cov teb chaws Europe xws li lub teb chaws Yelemees thiab Netherlands xav kom cov tuam txhab lag luam inverter teeb tsa cov hloov hluav taws xob hauv PV DC cais tawm, thaum lub teb chaws xws li United Kingdom, Is Nrias teb, thiab Australia xav kom cov tshuab hluav taws xob photovoltaic yuav tsum nruab sab nraud PV DC rho tawm keyboards.Nrog rau kev qhia meej ntawm Tuam Tshoj txoj cai photovoltaic, tus naj npawb ntawm kev teeb tsa photovoltaic tau nce xyoo los ntawm lub xyoo, tshwj xeeb tshaj yog rau cov tshuab photovoltaic, thiab cov tshuab ru tsev tau nrov dua.
Txawm li cas los xij, lub npe hu ua photovoltaic DC isolator hloov ntawm lub khw yog ib qhoAC isolator hloovlos yog hloov kho cov kab hluav taws xob, tsis yog DC rho tawm hloov nrog cov hluav taws xob hluav taws xob tiag tiag thiab lub zog hluav taws xob txiav tawm.Cov AC isolator keyboards no dhau lawm tsis muaj arc extinguishing thiab fais fab kev rho tawm ntawm lub load, uas tuaj yeem yooj yim ua rau overheating, to thiab sparks, thiab txawm hlawv tag nrho photovoltaic fais fab chaw nres tsheb.
Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tau xaiv ib tug tsim nyog lub hnub ci vaj huam sib luag dc isolator hloov.TS EN 60947-3 EN 60947-3 BS 7671 qhia txog kev sib cais yuav tsum tau muab rau ntawm DC sab ntawm kev teeb tsa photovoltaic.
Yog li, yuav ua li cas xaiv qhov tsim nyog PV DC rho tawm hloov rau lub tshuab photovoltaic?
Qhov ntsuas hluav taws xob ua haujlwm ntawm DC rho tawm hloov pauv yuav tsum sib npaug lossis ntau dua li qhov yuav tsum tau ua ntawm lub kaw lus.Feem ntau ntsib UL508i 600V, IEC60947-3 1000V thiab 1500V.Feem ntau qhov system voltage txuas nrog ib-theem inverter yog siab li 600V, thiab peb-theem hlua inverter lossis centralized inverter yog siab li 1000V lossis 1500V.
2 Ncej - Ib txoj hlua, 4 Ncej - Ob txoj hlua.
Rau lub built-in DC isolator hloov, tus naj npawb ntawm MPPT ntawm lub inverter txiav txim tus ncej ntawm DC cais.Cov hlua inverters muaj ib qho MPPT, dual MPPT, thiab me me ntawm triple MPPT.Feem ntau hais lus, inverters nrog lub zog ntsuas ntawm 1kW ~ 3kW txais yuav ib tus qauv MPPT;cov inverters nrog lub zog ntsuas ntawm 3kW ~ 30kW txais ob MPPT lossis me me ntawm peb MPPT.
Rau kev hloov pauv DC sab nraud, koj tuaj yeem xaiv 4 tus ncej, 6 tus ncej, 8 ncej rau ntau lub hnub ci vaj huam sib luag lossis 2 tus ncej rau cov txheej txheem hnub ci raws li kev tsim qauv sib txawv.
PV DC isolator hloov yuav tsum raug xaiv raws li qhov siab tshaj plaws voltage thiab tam sim no ntawm txoj hlua vaj huam sib luag.Yog tias tus neeg siv paub qhov tsis zoo ntawm photovoltaic inverters, tshwj xeeb tshaj yog cov tuam txhab inverter, thiaj li yuav txuag tau cov nqi, lawv tuaj yeem xaiv raws li cov tswv yim DC voltage thiab nkhaus tam sim no kom ntseeg tau tias lawv tuaj yeem siv tau rau txhua qhov huab cua thiab qhov kub thiab txias.
TS EN 60947-3 - Ntu 3: BS 7671 qhia tias kev hloov pauv hloov pauv raws li EN 60947-3 yog tsim rau cov tshuab photovoltaic.Tus nqi ntsuas ntawm qhov hloov hluav taws xob cais yuav tsum xav txog qhov siab tshaj plaws voltage thiab tam sim no ntawm cov hlua photovoltaic kom cais tawm, thiab tom qab ntawd kho cov kev txwv no raws li qhov kev nyab xeeb tau teev tseg los ntawm tus qauv tam sim no.Qhov no yuav tsum yog qhov ntsuas qhov tsawg kawg nkaus uas yuav tsum tau muaj rau qhov hloov pauv hloov pauv.
Qhov chaw ua haujlwm kub, qib kev tiv thaiv thiab qib tiv thaiv hluav taws yuav tsum tau txiav txim siab raws li ib puag ncig.Feem ntau qhov zoo PV DC rho tawm hloov pauv tuaj yeem siv tau zoo ntawm qhov ntsuas kub ntawm -40 ° C txog 60 ° C.Feem ntau, qib kev tiv thaiv ntawm sab nraud DC rho tawm hloov yuav tsum ncav cuag IP65;Lub built-in DC rho tawm hloov yuav tsum xyuas kom meej tias cov cuab yeej ncav cuag IP65.Qhov ntsuas hluav taws kub ntawm lub thawv tsev lossis lub cev tseem ceeb yuav tsum ua raws li UL 94V-0, thiab tus kov yuav tsum ua raws li UL 94V-2.
Cov neeg siv tuaj yeem xaiv hom tsim nyog raws li qhov xav tau tiag tiag.Feem ntau, muaj vaj huam sib luag installation, hauv paus installation thiab ib lub qhov installation.
