Yuav ua li cas photovoltaic zog tsim system yuav tsum tau nrog xob laim?

ଲେଖକ: ଆଇଫ୍ଲୋପାୱାର - Dobavljač prijenosnih elektrana

Qhov tsawg kawg nkaus qhov hluav taws xob ntawm lub tshuab hluav taws xob photovoltaic yog 1.0kV. Thaum xob laim inductive voltage, tam sim no ntau dua li cov khoom siv siab ntev, cov khoom siv yuav ua rau cov khoom puas.

Los ntawm decomposition, thawj qhov zoo polarity xob laim tawm tsam, thawj lub teeb pom kev tsis zoo, thawj lub teeb pom kev tsis zoo, qhov kev nyab xeeb ntawm kev sib raug zoo nrog cov xwm txheej xob laim yog 5.1, 25.2, 50.

4,8m 9. Raws li cov saum toj no decomposition, lub hnub ci photovoltaic lub zog tsim hluav taws xob yuav tsum tau teeb tsa kev tiv thaiv ncaj nraim mine li raws li hom thib ob ntawm xob laim tiv thaiv lub tsev, tab sis kuj tau txais kev tiv thaiv flash surge invasion thiab xob laim tiv thaiv electromagnetic pulse ntsuas kom xob laim tawm tsam induced voltage, induction tam sim no tswj nyob rau hauv nws kam rau ua.

Kev tiv thaiv ncaj nraim thiab grounding hnub ci photovoltaic roj teeb board protruding lub dav hlau 0.45m tsim los ntawm cov thawj teeb pom kev zoo sawb, kom lub flash tiv thaiv lub zog tsim system. Lub flash tuaj yeem tiv thaiv los ntawm lub teeb nyem, kab, thiab lub network.

Txij li thaum lub roj teeb lub rooj tsavxwm yog loj, lub flash kab yog siv, lub flash network muaj lub hom phiaj tiv thaiv, tab sis cov hlau thiab mesh yog teem rau ntawm lub roj teeb lub rooj tsavxwm. Cov duab ntxoov ntxoo raug thaiv rau lub sijhawm ntev Lub Rooj Tswjhwm Saib Xyuas Lub Zog, cuam tshuam rau lub zog tsim hluav taws xob. Qhov tsim nyog rau ntau qhov kev ywj pheej flasher yog teem rau hauv lub eaves ntawm lub tsev, lub ces kaum thiab cov zoo li yog yooj yim mus rau lub xob laim ntaus, tus pas nrig ntawm lub flale pas nrig yog 0.

5m, thiab eaves tau teem txhua 5m, thiab lub hauv paus kaum sab xis yog encrypted. Qhov tsim ob tug ncej thiab ntau tus ncej tiv thaiv yuav txo tau qhov siab thiab qhov ntau ntawm cov pas nrig flash. Lub flash pas nrig thiab lub rooj cob qhia muaj kev sib txuas ruaj khov, nruab nrab ntawm aluminium alloy ciam teb ntawm lub hnub ci vaj huam sib luag, thiab cov hlau bracket, thiab cov roj teeb uas nyob ib sab tsis pub tsawg dua 10 hli 2 ntau txoj hlua tooj liab, tsim M-type grid qauv.

Txoj kev hluav taws xob yog tsim los, thiab xob laim tau dhau mus zoo thiab xa mus rau lub ntiaj teb. Hnub ci fais fab grounding systems muaj xws li xob laim tiv thaiv hauv av, muaj kev nyab xeeb thiab tiv thaiv, ncaj qha-flowing functional grounding. Txhua lub hauv paus hauv av yog qhov nyuaj rau kev ywj pheej, txhawm rau tiv thaiv cov av muaj peev xwm tawm tsam ntawm cov hauv av, cov khoom siv, cov khoom siv hlau, cov pob zeb hauv av, thiab lwm yam.

, ua ib qho kev sib koom grounding network, kev npaj hauv av network thiab qhov loj yog nruj dua li qhov tshwj xeeb hauv av tiv thaiv tus nqi, lub hauv paus network yuav tsum tau siv nyob rau hauv lub hauv paus los yog nplhaib phau ntawv grounding network. Qhov av tiv thaiv tus nqi yuav tsum tsawg dua 1 <000000>, qhov chaw ntsuas qhov nruab nrab thaj av network yog 0.8 <000000>, raws li qhov yuav tsum tau ua.

Anti-flashing tam sim no yog ua raws li cov qauv ntawm lub hnub ci photovoltaic system thiab thunder yoj invasive txoj kev, uas tuaj yeem tawm hauv cov kab hauv kab, uas tuaj yeem tso tawm cov cua ntsawj ntshab, txwv overvoltage, thiaj li tiv thaiv cov khoom tiv thaiv. Ua siab ntev. Ntawm lub thawv ntws tau qhia nyob rau hauv qhov hluav taws xob nthwv dej, LPZ0 cheeb tsam tau teeb tsa rau SPD ntawm hom I kev faib tawm ntawm qhov sib txuas ntawm LPZ1 cheeb tsam, uas tiv thaiv qib 1.

Txhim kho SPD ntawm hom II kev faib tawm kev xeem ntawm tus maub los raws li kev tiv thaiv qib thib ob, txhim kho Qib 3 SPD ntawm lub inverter. Nruab qib 4 SPD nyob rau pem hauv ntej kawg ntawm DC load thiab AC load, raws li qhov kawg precision tiv thaiv. SPDs rau kev txhim kho Class I xeem nyob rau sab siab siab ntawm transformer, lub defensive daim phiaj sab xob laim nthwv dej qhia txog xob laim hluav taws xob tsis zoo.

Cov khoom siv sib txuas lus thiab lub thawv tsheb, xws li, teeb liab kab ntawm inverters Nruab adaptation teeb liab surge tiv thaiv ntaus ntawv. Kev tiv thaiv hluav taws xob hluav taws xob hluav taws xob kom txo tau cov hluav taws xob hluav taws xob hluav taws xob hluav taws xob los tsim cov tshuab hluav taws xob photovoltaic, ua ntej siv cov khoom siv ntuj tsim thiab kev tiv thaiv hluav taws xob, cov cuab yeej tiv thaiv hluav taws xob, cov cuab yeej tiv thaiv hluav taws xob, thiab lwm yam. Cov cuab yeej siv hluav taws xob photovoltaic, txee, thiab hlau casing ntawm cov hlau casing ntawm lub hwj huam mov txee kuj yog ze rau cov cuab yeej tiv thaiv; thib ob, lub hwj chim cable ntawm photovoltaic system, lub teeb liab kev sib txuas lus cable yog nteg los yog hloov nrog ib tug shield cable, hlau Lub raj los yog ntaub thaiv npog yuav tsum tau grounded nyob rau hauv ob qho tib si kawg thiab yog txuas nrog nyob rau hauv sib npaug zos peev xwm los ntawm lub lightningirening cheeb tsam.

Lub zog hluav taws xob nruab nrab ntawm thaj tsam LPZ0, cov khoom siv hluav taws xob, cov khoom siv sib txuas lus, ob qhov kawg ntawm lub raj hlau uas hnav cov teeb liab kab yuav tsum tau txuas nrog cov khoom siv hlau casing, lub thawv xa khoom thiab txuas nrog cov khoom siv tiv thaiv hluav taws xob ze. Thaum txhua txoj hlua hluav taws xob yuav tsum tiv thaiv ib cheeb tsam loj ntawm electromagnetic induction voj, nteg cov kab hluav taws xob sib txawv ntawm cov voj voog sib txawv thiab kev khiav hauj lwm voltages, thiab cov kab teeb liab tau muab tso rau hauv cov kab sib txawv, thiab cov ntaub ntawv kaw lus cable thiab xob laim tiv thaiv qhov tsawg kawg nkaus ntawm 1000mm qib. Qhov sib txawv thiab 300mm interleaving net.
