Kev tiv thaiv kev kub ntxhov yog qhov tseem ceeb thaum tiv thaiv koj lub tshuab hluav taws xob, tshwj xeeb tshaj yog cov tshuab hluav taws xob ncaj qha (DC) . Lub DC Surge Protection Device (DC SPD) yog tsim tshwj xeeb los tiv thaiv DC Cheebtsam los ntawm corrosive voltage spikes, hu ua surges lossis transients. Cov hluav taws xob hluav taws xob zoo li no tshwm sim rau ntau qhov laj thawj, xws li xob laim, hluav taws xob hluav taws xob, lossis hloov cov khoom siv hluav taws xob loj. Yog tias koj muaj kev kub ntxhov siab, nws tuaj yeem ua mob hnyav rau cov khoom siv hluav taws xob zoo li inverters, roj teeb, rectifiers, thiab lwm yam ntawm koj lub cev.
Hauv qhov no,DC SPDtiv thaiv koj cov cuab yeej los ntawm overvoltage los ntawm kev thaiv thiab tshem tawm kom nws nyob nyab xeeb thiab ua haujlwm. Thaum nws los txog rau lub hnub ci hluav taws xob, lub zog cia hauv tsev, lossis lwm yam DC-powered system, koj yuav tsum tau txais kev tiv thaiv kev ruaj ntseg kom ntseeg tau tias kev ua haujlwm ntev ntawm koj lub cev.
Kev tiv thaiv surge yog ib qho system uas thaiv los yog shunts lub zog ntau dhau rau hauv av thaum muaj kev kub ntxhov. Nws ua li ntawd los ntawm kev siv cov khoom tshwj xeeb xws li hlau oxide varistors (MOVs), cov roj tso tawm (GDTs), lossis silicon-tswj rectifiers (SCRs), uas yuav nqa tam sim no ua tau zoo thiab nrawm los ntawm qhov xwm txheej tshwm sim. Thaum lub surge yog generated, cov khoom tam sim ntawd hloov cov hluav taws xob ntau dhau mus rau hauv av, nqa cov seem ntawm lub voj voog nyob rau hauv kev nyab xeeb.
Cov surges tam sim no tshwj xeeb yog kev puas tsuaj nrog DC circuits, uas muaj feem ntau tsis sib xws. DC SPDs yog tsim los teb sai thiab ruaj ntseg lub kaw lus ua ntej nws tuaj yeem txhawb nqa kev puas tsuaj mus ntev. Lub module tswj lub system txoj kev ncaj ncees los ntawm kev ua kom lub surge tsis tshaj qhov siab tshaj plaws uas tau txais voltage rau ib feem ntawm lub Circuit Court.
Cov surges yeej ib txwm nce, tab sis lawv qhov cuam tshuam yog tiag tiag. Hauv lwm qhov xwm txheej, ib qho kev nce siab tuaj yeem rhuav tshem cov khoom siv rhiab thiab ua rau raug nqi kho lossis hloov pauv. Nov yog qee qhov laj thawj vim li cas kev tiv thaiv surge tseem ceeb heev:
Tiv thaiv los ntawm xob laim Strikes:Nyob rau hauv cov cheeb tsam cua daj cua dub, xob laim cua daj cua dub tuaj yeem tsim cov hluav taws xob muaj zog uas ncav cuag cov kab hluav taws xob thiab cov khoom siv hluav taws xob puas. Lub DC SPD txuag koj lub cev los ntawm cov xwm txheej no los ntawm clamping ntau qhov hluav taws xob sai.
Fais fab tuag kab:Kev hloov pauv hauv daim phiaj hluav taws xob vim hloov pauv lossis tsis ua haujlwm ntawm cov kab hluav taws xob nyob ze tuaj yeem ua rau muaj hluav taws xob cuam tshuam rau koj cov khoom siv. DC SPD ua raws li daim thaiv tiv thaiv cov spikes.
Sudden Load Switching:Thaum lub kaw lus hloov hluav taws xob loj loj rau lossis tawm, qhov sib cuam tshuam tuaj yeem tsim tau. DC SPDs tau tsim los daws cov teeb meem no.
Khoom siv ntev:Cov cuab yeej tshwj xeeb, xws li inverters thiab roj teeb, tuaj yeem raug rhuav tshem yooj yim los ntawm surges. Thaum siv DC SPD, koj lub kaw lus yuav ua tsis tau tsawg dua, uas ua rau koj lub neej ua haujlwm thiab txo qis qis.
Tiv thaiv hluav taws kub:Qhov hluav taws xob ntau dhau yuav ua rau cov cuab yeej ua kom sov thiab pib hluav taws. Lub tsev tiv thaiv hluav taws xob hauv tsev khaws cov khoom siv hauv qhov chaw ua haujlwm nyab xeeb kom tsis txhob muaj cua sov dhau.
Lub Low Voltage Arrester Surge Protection Device peb muag muaj ntau lub peev xwm tseem ceeb uas ua rau nws muaj kev xaiv ntse los tiv thaiv koj lub tshuab. Cov no suav nrog:
Wide Voltage Band:Lub tshuab tuaj nyob rau hauv ntau yam qauv uas khiav ntawm qhov sib txawv voltages. Koj tuaj yeem xaiv los ntawm 1000V, 1200V, lossis 1500V, thiab yog li ntawd, nws yog qhov tsim nyog rau txhua qhov DC system, los ntawm cov khoom siv hauv tsev me mus rau cov tsev lag luam loj.
Kev Tiv Thaiv Kev Tiv Thaiv 20kA / 40kA:Kev tiv thaiv kev kub siab txog li 20kA / 40kA ntawm qhov SPD no tiv thaiv koj lub computer los ntawm lub zog hluav taws xob. Txawm hais tias koj siv lub tsev me me lossis cov PV loj heev, cov khoom siv no tiv thaiv koj zoo.
Sijhawm teb sai:DC SPD instantly reacts rau tam sim no voltage spikes, tiv thaiv koj lub cev ua ntej kev puas tsuaj. Qhov teeb meem ceev ceev, vim tias qhov hluav taws xob ntau dhau tuaj yeem rhuav tshem cov khoom siv hluav taws xob.
Hnub ci PV tiv thaiv:Kev siv nrov tshaj plaws ntawm DC surge tiv thaiv yog nyob rau hnub ci photovoltaic (PV) panels qhov twg xob laim thiab hluav taws xob tsis ua hauj lwm yog qhov txaus ntshai. Peb cov DC SPDs tau tsim tshwj xeeb rau cov hnub ci inverters thiab roj teeb thiab tau tsim tshwj xeeb los tiv thaiv cov txheej txheem no.
Kev tsim kho muaj zog:Peb DC SPD yog qhov ruaj khov heev, siv cov khoom zoo. Nws tuaj yeem zam qhov kev nce siab tas mus li thiab ua kom koj lub cev muaj kev nyab xeeb rau lub sijhawm ntev yam tsis tas yuav hloov pauv.
Solar Power Systems:Ntau tus neeg thiab cov lag luam siv lub hnub ci zog, hnub ci inverters, roj teeb, thiab lwm yam tseem ceeb yuav tsum tau tiv thaiv los ntawm kev puas tsuaj loj. Peb DC SPDs ua kom koj lub hnub ci zog ua haujlwm zoo yam tsis muaj kev cuam tshuam los ntawm kev nce siab.
Zog Cia:Raws li kev siv lub zog khaws cia ntau dua (piv txwv li, kev teeb tsa lub roj teeb hauv tsev), tsis tas yuav muaj kev tiv thaiv surge ntau dua. Cov no feem ntau ua ke nrog cov hnub ci vaj huam sib luag thiab tshwj xeeb tshaj yog raug rau kev nce siab. Tswj koj txoj haujlwm hauv DC SPD kom ntseeg tau tias cov khoom nce thiab nqis.
Telecommunications Hardware:Ntau yam khoom siv sib txuas lus yog siv los ntawm DC lub zog thiab cov khoom siv kuj tuaj yeem ua rau muaj qhov hluav taws xob sib kis. DC SPD yog qhov zoo tshaj plaws rau kev tiv thaiv cov tshuab no los ntawm kev tawg thiab tso cai rau lawv ua haujlwm ib txwm.
Tsheb (EVs):Nrog kev nce ntawm lub tsheb fais fab, kev tiv thaiv kev tiv thaiv ntawm cov chaw them nyiaj thiab DC-based charging systems yog qhov tseem ceeb. Lub DC SPD tiv thaiv kev puas tsuaj rau lub tsheb them nyiaj.
Tus nqi txo:Tsawg dua kev kho lossis hloov pauv vim muaj kev puas tsuaj rau cov khoom siv. Thaum koj yuav DC SPD, koj tiv thaiv koj cov cuab tam thiab txo qhov kev pheej hmoo ntawm cov nqi npaj txhij.
Kev ua haujlwm zoo dua qub:Lub kaw lus tiv thaiv ua haujlwm zoo dua, nrog kev cuam tshuam tsawg dua vim yog hluav taws xob yuam kev. Nrog DC SPD, koj lub zog hluav taws xob tseem yuav ua haujlwm zoo.
Txhim kho kev nyab xeeb:Thaum muaj cua sov los yog hluav taws kub nyhiab, nws yog qhov txaus ntshai. Cov kev hem thawj no tuaj yeem raug tshem tawm los ntawm kev siv lub zog tiv thaiv los tiv thaiv koj lub tsev, chaw ua haujlwm, thiab cov khoom muaj nqis.
Zhejiang Mulang Electric Co., Ltd. Los ntawm nws cov chaw tsim khoom lag luam, kev siv zog ua haujlwm, thiab cov txheej txheem kev ruaj ntseg zoo, Mulang Electric tau tsim nws tus kheej ua lub tuam txhab uas muab cov khoom siv hluav taws xob zoo, ruaj khov.
