Hnub tim: Dec-02-2024
Niaj hnub no, technology tau dhau los ua qhov tseem ceeb ntawm peb lub neej thiab kev tiv thaiv peb cov khoom siv hluav taws xob thiab cov tshuab hluav taws xob tseem ceeb dua. Cov neeg feem coob xav txog cov khoom siv uas tau teeb tsa rau ntawm AC cov kab hluav taws xob thaum nws los txog rau kev tiv thaiv hluav taws xob, tab sis qhov xav tau ntawm DC surge tiv thaiv cov cuab yeej tau nce ntxiv hauv xyoo tas los no. Qhov no yog vim qhov nce ntawm lub zog tauj dua tshiab thiab nce ntxiv ntawm DC powered li. Cov duab hauv qab no yog cov qauv kev ua haujlwm, qhov tseem ceeb thiab yuav ua li cas DC surge tiv thaiv cov cuab yeej tiv thaiv peb cov tshuab hluav taws xob.
· DC surge tiv thaiv cov khoom siv feem ntau hu ua DC SPDs yog cov khoom siv hluav taws xob ua ntej los tiv thaiv DC-powered apparatus thiab cov qauv los ntawm cov hluav taws xob nrawm nrawm uas tshwm sim los ntawm kev ua haujlwm tam sim no. Cov hluav taws xob tawm tsam, hloov chaw ua haujlwm, cuam tshuam hluav taws xob (EMI), lossis hluav taws xob tsis ua haujlwm ua rau muaj qhov sib txawv.
· Lub luag haujlwm tseem ceeb ntawm DC Surge Protector yog tswj kom muaj nuj nqis tam sim no uas tau dhau mus rau cov khoom siv qis qis thiab ua rau lub zog ntau dhau kev nyab xeeb rau cov minced. Li no nws pab tiv thaiv kev puas tsuaj rau cov khoom siv rhiab uas suav nrog cov roj teeb, inverters, rectifiers, thiab lwm yam khoom siv tseem ceeb hauv DC lub zog.
· Nrog rau txoj kev txhim kho kom zoo, koj yuav nyob rau hauv txoj hauj lwm ntawm kev npog ntau qhov kev poob uas tuaj yeem tshwm sim los ntawm spikes. Cov phom sij ntawm cov hluav taws xob hluav taws xob no suav nrog hluav taws kub hnyiab, lossis txawm tias muaj hluav taws xob hluav taws xob.
· Vim yog siv o ntawm kev siv hluav taws xob tauj dua tshiab raws li tau hais ua ntej, piv txwv; cua turbines thiab hnub ci photovoltaic (PV) panels. Cov tshuab no feem ntau tsim hluav taws xob DC, uas yuav tsum tau muaj kev tiv thaiv kom zoo los ntawm qhov hluav taws xob tsis zoo. Qhov no tau pab rau qhov kev thov siab dua rau DC surge tiv thaiv cov cuab yeej.
· Nrog rau tus qauv mounting rail, qhov no nruj buckle nrees stick qhia rail installation yog ib qho tseem ceeb, koj tau qhia kom siv nws tsis muaj kev txhawj xeeb. Tag nrho cov sequestered davhlau ya nyob twg, uas yog qhov loj qhov threaded davhlau ya nyob twg rail hom thaiv yog firmer thiab yooj yim.
· Tsis tas li ntawd, yuav tsum muaj kev tiv thaiv kev tiv thaiv zoo dua li cov khoom siv hluav taws xob ntau dua, xws li cov chaw zov me nyuam cov ntaub ntawv, kev sib txuas lus, thiab cov tsheb hluav taws xob, cia siab rau DC lub zog. Cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob tsis zoo tuaj yeem ua rau puas tsuaj, ua rau muaj kev poob qis thiab muaj peev xwm muaj kev nyab xeeb yog tias tsis muaj kev tiv thaiv zoo.
Nws yog ib qho tseem ceeb rau kev cuam tshuam nrog cov khoom siv interface; qhov no yuav pab kom koj nkag siab txog cov khoom tsim nyog yuav khoom. Zhejiang Mulang Electric Co., LtdDC SPDsnrog lawv lub logo tshwj xeeb, siv los ntawm MLY1-C40 ntawm DC1000V thiab siab dua.
DC surge tiv thaiv cov cuab yeej muaj ntau yam khoom ua haujlwm ua ke los hloov cov surge tam sim no thiab tiv thaiv cov khoom siv hauv qab. Cov khoom tseem ceeb suav nrog;
- MLY 1 modular
- Hlau oxide varistors (MOVs)
- Gas Discharge tubes (GDTs)
- Transient voltage suppression diodes (TVS diodes)
Fuses
Qhov hluav taws xob tiv thaiv hluav taws xob no yog siv los tiv thaiv qhov nce siab coj los ntawm lub teeb pom kev zoo thiab tam sim no overvoltage. Pab tso tawm lub zog loj loj ntawm txoj kab hluav taws xob mus rau lub ntiaj teb uas nyob hauv av kom txwv tsis pub dhau lub zog.
MOVs yog nonlinear voltage-dependent controllers uas retort rau voltage spikes los ntawm muab ib tug tsawg-confrontation txoj kev rau lub zog ntxiv. Lawv engross lub surge tam sim no thiab sidetrack nws yam xyuam xim rau hauv av, tiv thaiv cov khoom txuam.
GDTs yog hermetically kaw cov khoom ntim nrog cov roj av qeeb uas ionize thaum raug hluav taws xob siab. Lawv tsim txoj kab hluav taws xob rau lub zog surge, ua kom lub zog nrawm thiab nyeem lub zog kom deb ntawm cov cuab yeej hloov maj mam.
TVS diodes yog cov khoom siv semiconductor tsim los cuam tshuam lub zog txav deb ntawm cov khoom siv hluav taws xob me me. Lawv muaj qhov tsis tshua muaj hluav taws xob tawg thiab teb sai sai rau cov hluav taws xob hluav taws xob, shunting cov tam sim no ntau dhau rau hauv av.
fuses ua raws li kev tiv thaiv kev tsim nyog los ntawm kev nkag mus ntawm qhov tsis tsim nyog tam sim no. Lawv yog cov txheej txheem kev txi uas liquefy thaum lub zog nce siab tshaj lawv cov ntim ntim, txwv tsis pub muaj kev phom sij ntau rau cov cuab yeej txuas.
Muaj cov lus qhia siv koj yuav tsum tau ntws tom qab yuav cov DC SPDs los tiv thaiv koj cov khoom hluav taws xob. Cov no suav nrog;
- Siv nws ntawm 50Hz thiab 60Hz AC
- Nruab nws hauv qab 2000m saum hiav txwv theem
- Kev khiav hauj lwm ib puag ncig kub -40, +80
- Nrog MLY1, qhov hluav taws xob ntawm lub davhlau ya nyob twg yuav tsum tsis pub tshaj nws qhov siab tshaj plaws txuas ntxiv ua haujlwm voltage
- Tus qauv 35mm qhia rail installation
Thaum muaj qhov hluav taws xob hluav taws xob tshwm sim, DC surge tiv thaiv ntaus ntawv pom qhov hluav taws xob ntau dhau thiab ua rau lub tshuab tiv thaiv. Cov MOVs, GDTs, thiab TVS diodes muab txoj hauv kev uas tsis tshua muaj siab rau cov surge tam sim no, hloov nws mus rau hauv av.
Cov fuses, ntawm qhov tod tes, ua raws li txoj kab kawg ntawm kev tiv thaiv los ntawm kev cuam tshuam cov dej ntws tam sim no yog tias nws tshaj qhov ntsuas qhov siab tshaj plaws. Los ntawm kev txwv qhov hluav taws xob txaus, DC SPDs xyuas kom meej tias cov khoom siv hauv qab tau txais kev ruaj khov thiab tiv thaiv hluav taws xob.
Qhov zoo tshaj plaws ntawm kev siv DC surge fortification li yog khaws cia ntawm cov khoom siv txuas los ntawm qhov hluav taws xob surges. Lifespan ntawm cov cuab yeej siv tau txuas ntxiv vim yog kev tiv thaiv kev puas tsuaj thiab kev poob qis los ntawm kev hloov pauv ntawm lub zog tsis zoo.
Cov hluav taws xob hluav taws xob tuaj yeem ua rau muaj kev nyab xeeb tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv qhov chaw muaj kev pheej hmoo siab xws li cov chaw khaws ntaub ntawv lossis chaw nres tsheb fais fab. DC SPDs muab cov txheej txheem ntxiv ntawm kev nyab xeeb los ntawm kev txo qis qhov tshwm sim ntawm hluav taws kub, hluav taws xob poob siab, lossis khoom siv tsis ua haujlwm.
Cov tshuab hluav taws xob tuaj yeem ua tau zoo dua nrog DC surge tiv thaiv cov cuab yeej hauv tsev. Qhov txo qis ntawm kev ua tsis tiav tam sim lossis ua haujlwm tsis zoo ua kom tsis muaj kev cuam tshuam cov khoom siv hluav taws xob, ua rau muaj txiaj ntsig zoo thiab cov neeg siv khoom txaus siab.
Hauv lub ntiaj teb tam sim no uas cov khoom siv hluav taws xob thiab cov tshuab hluav taws xob txuas ntxiv tau ua lub luag haujlwm tseem ceeb rau peb lub neej ntawm kev tiv thaiv peb ntawm qhov hluav taws xob surges txaus ntshai tsis tuaj yeem ntsuas.DC surge tiv thaiv cov cuab yeejua lub luag haujlwm tseem ceeb hauv kev tiv thaiv DC-powered cov cuab yeej thiab cov tshuab los ntawm cov xwm txheej hloov hluav taws xob. Nws yog ib qho tseem ceeb kom nkag siab txog cov hauv paus ntsiab lus ntawm kev ua haujlwm, thiab cov txiaj ntsig uas lawv muab raws li qhov no tuaj yeem lav kev ntseeg siab thiab kav ntev ntawm peb lub neej thiab kev teeb tsa hluav taws xob. Xav txog kev nqis peev hauv DC SPDs txhawm rau txo cov kev pheej hmoo cuam tshuam nrog kev nce hluav taws xob thiab khaws peb cov khoom muaj txiaj ntsig xws li PV system ntawm koj lub ru tsev lossis kev sib txuas lus tseem ceeb.
Tiv tauj peb
