Qhov tseem ceeb ntawm surge protector hauv photovoltaic zog tsim

Zoo li txhua yam khoom siv hluav taws xob, hnub ci arrays tuaj yeem tsim cov hluav taws xob hluav taws xob uas tuaj yeem ua rau cov khoom puas thiab ua rau lub cev tsis zoo.surge tiv thaiv ntaus ntawvpab kom lub kaw lus khiav.

Xav txog lub computer hauv tsev lossis chaw ua haujlwm.Ntxiv rau desktops lossis laptops, tej zaum yuav muaj cov saib sab nraud, hais lus lossis txawm tias cov tshuab luam ntawv.Ntau yam khoom tsis tuaj yeem ntsaws rau hauv lub qhov hluav taws xob ntawm phab ntsa, yog li cov neeg feem coob yuav ib lub keyboards.Txawm li cas los xij, lub vaj huam sib luag tsis yog ib txoj hauv kev yooj yim los lo ib pawg ntawm cov khoom rau hauv lub qhov (socket).Nws yeej pab tiv thaiv cov khoom siv hluav taws xob no los ntawm kev puas tsuaj ntawm cov surges.

Ib qho surge, tseem hu ua ib qho hluav taws xob hloov pauv, feem ntau yog hais txog qhov hloov pauv hloov pauv hauv qhov hluav taws xob uas siab dua li qub.Piv txwv li, tus qauv voltage rau lub tsev lossis chaw ua haujlwm yog 120V.Voltage tuaj yeem xav tias yog hluav taws xob siab.Yog li, ib yam li dej ntau dhau tuaj yeem ua rau lub vaj hose tawg, qhov hluav taws xob siab dhau tuaj yeem ua rau hluav taws xob puas tsuaj.Cov surges no tuaj yeem yog los ntawm tej yam ntuj tso, xws li xob laim, thiab los ntawm cov khoom siv sab hauv lossis cov khoom siv hluav taws xob sab hauv ntawm daim phiaj hluav taws xob.

Cov cuab yeej tiv thaiv hluav taws xob pab tiv thaiv kev puas tsuaj rau cov khoom siv hluav taws xob los ntawm kev xa cov hluav taws xob ntau dhau los ntawm "Kub" cov kab hluav taws xob mus rau hauv av.Nyob rau hauv feem ntau surge protectors, qhov no yog ua tiav los ntawm hlau oxide varistors (MOV), uas yog hlau oxides txuas nrog lub hwj chim thiab hauv av xaim los ntawm ob lub semiconductors.

Hnub ci zog xav tau Surge Protector

Lub hnub ci vaj huam sib luag kuj tseem yog cov khoom siv hluav taws xob, thiab yog li ntawd muaj kev pheej hmoo ntawm kev puas tsuaj loj.Lub hnub ci vaj huam sib luag yog qhov tshwj xeeb tshaj plaws rau xob laim hluav taws xob vim lawv qhov chaw loj thiab lawv qhov chaw nyob hauv qhov chaw raug, xws li ntawm lub ru tsev lossis hauv qhov chaw qhib hauv av.

Cov neeg cog lus hnub ci tsis tas yuav paub seb lawv puas tab tom tsim nyob rau hauv ib cheeb tsam uas muaj kev cuam tshuam rau xob laim.Muab cov ntaub ntawv los ntawm US Lightning Detection Network rau hauv cov cuab yeej pub dawb uas tso cai rau cov neeg cog lus hnub ci los ntsuas qhov teeb meem ntawm lawv txoj haujlwm.

xob laim yog li 50,000 ° F (tsib zaug siab dua lub hnub), yog li nws tsis xav tsis thoob tias nws yuav ua rau muaj teeb meem rau cov khoom siv hnub ci.Yog tias koj ntaus lub hnub ci vaj huam sib luag ncaj qha, xob laim yuav hlawv qhov hauv lub cuab yeej lossis txawm tias ua rau tawg, thiab tag nrho lub cev yuav raug puas tsuaj.

Txawm li cas los xij, qhov cuam tshuam ntawm teeb pom kev zoo thiab lwm yam overvoltages tsis yog ib txwm tseem ceeb.Qhov cuam tshuam thib ob ntawm cov xwm txheej no yuav cuam tshuam tsis yog tsuas yog cov khoom tseem ceeb xws li modules thiab inverters, tab sis kuj tseem muaj cov kab ke soj ntsuam, cov chaw tswj xyuas thiab chaw huab cua, Sirava tau hais.

xob tiv thaiv

Cov teebmeem thib ob feem ntau yog qhov txaus ntshai tsawg tshaj plaws.PV module poob txhais tau tias txoj hlua poob, thaum lub hauv paus inverter poob yuav txhais tau tias lub zog poob hauv feem ntau ntawm cov nroj tsuag.

Installation ntawm surge protector

Vim tias tag nrho cov khoom siv hluav taws xob tsuas yog cuam tshuam los ntawm kev nce siab, SPD tuaj yeem siv rau txhua lub hnub ci array.Muaj cov qauv ntawm cov khoom siv no kuj tseem siv ua ke ntawm cov hlau oxide varistors (MOV) thiab lwm yam khoom siv haphazard kom xa cov surge overvoltage rau hauv av.Yog li ntawd, SPD feem ntau yog ntsia tom qab qhov chaw ruaj ntseg hauv av nyob hauv qhov chaw.

Siv rau hauv daim duab hluav taws xob ib leeg-kab ntawm SPD cascade los ntawm kev pabcuam hluav taws xob rau cov khoom siv array, nrog cov khoom siv tu kom ruaj khov ntawm qhov chaw nkag, kom tsis txhob muaj kev hloov pauv loj thiab cov khoom me me mus txog qhov kawg ntawm cov cuab yeej raws txoj hauv kev tseem ceeb.

SPD cov tes hauj lwm yuav tsum tau muab tso rau hauv AC thiab DC faib thoob plaws hauv lub hnub ci array kom tswj xyuas qhov tseem ceeb.SPD ntaus ntawv yuav tsum tau mounted rau ntawm DC input thiab AC tso zis ntawm lub system inverter, thiab cov zoo thiab tsis zoo DC kab yuav tsum tau grounded thaum grounded.Kev saib xyuas AC yuav tsum tau muab tso rau ntawm txhua txoj kab hluav taws xob hauv av.Cov kab hluav taws xob sib txuas kuj tseem yuav raug tswj xyuas, thiab tag nrho cov tswj Circuit Court thiab txawm tias cov kev soj ntsuam thiab kev soj ntsuam yuav tsum tau tswj kom tsis txhob muaj kev cuam tshuam thiab cov ntaub ntawv poob.

Hais txog cov txheej txheem ntawm kev lag luam thiab kev npaj siv hluav taws xob, txoj cai 10m raug pom zoo.Rau cov khoom siv nrog DC cable ntev tsawg dua 10m (33ft), DC hnub ci kev tiv thaiv hluav taws xob yuav tsum nyob hauv qhov chaw yooj yim, xws li qhov chaw ntawm lub inverter, lub thawv tsheb npav lossis ze ntawm lub hnub ci module.Rau cov khoom siv nrog DC cable ntev tshaj 10m,solar surge tiv thaiv ntaus ntawvyuav tsum tau ntsia ntawm lub inverter kawg ntawm lub inverter thiab lub module kawg ntawm lub cable.

Lub hnub ci vaj tsev nyob nrog cov me me inverters muaj luv luv DC cables, tab sis ntev AC cables.Lub SPD mounted rau ntawm lub manifold tuaj yeem tiv thaiv lub tsev los ntawm cov teebmeem ntawm array surge.Ntxiv nrog rau cov surges los ntawm lub nroog hwj chim thiab lwm yam khoom siv sab hauv, surge protectors ntawm lub motherboard kuj tiv thaiv lub tsev ntawm array surges.

Hauv cov kab ke ntawm txhua qhov loj me, SPD yuav tsum tau ua los ntawm cov kws tshaj lij hluav taws xob muaj ntawv tso cai ntawm cov lus qhia ntawm cov chaw tsim khoom thiab ua raws li kev teeb tsa thiab kev teeb tsa hluav taws xob kom ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo.

Lwm cov txheej txheem tuaj yeem siv tau, xws li ntxiv cov hlua hluav taws xob ntxiv kom tswj cov hnub ci vaj huam sib luag los ntawm teeb pom kev zoo.

Txawm tias lub hom phiaj tseem ceeb tshaj plaws kev saib xyuas muaj zog muaj nws cov kev txwv.Piv txwv li, SPD tsis tuaj yeem zam lub cev puas tsuaj los ntawm kev raug hluav taws xob ncaj qha.
