PV Surge Protection Device Hnub Ci Vaj Huam Sib Luag DC Surge Protective Device SPD

Qhov cuam tshuam ntawm kev ncaj qha lossis tsis ncaj lub teeb hluav taws xob ua rau nws nkag mus rau hauv hluav taws xob hluav taws xob tuaj yeem ua kev puas tsuaj loj. Yog tias muaj kev puas tsuaj loj tshwm sim los ntawm kev teeb tsa ces tus neeg teb xov tooj tau ntsib nrog kev kho nqi siab rau cov cuab yeej siv thiab qhov poob ntawm cov nyiaj tau los vim qhov khoom ploj. Raws li qhov tshwm sim ntawm qhov no, nws yog qhov tseem ceeb tias cov surges raug cuam tshuam ua ntej lawv tshem tawm tag nrho cov kab ke los ntawm kev ua kom cov PV xaj xaim, lub plhaw tswj / inverter thiab lub thawv sib xyaw.

LSP muaj peev xwm txo tau tawm tsam cov kev hem no los ntawm kev muab cov kev tiv thaiv zoo rau cov qhua tuaj noj mov. Cov kab ntau ntawm cov ntawv pov thawj PV DC tiv thaiv kev tiv thaiv zoo muaj nyob rau hauv kev tiv thaiv kev tiv thaiv hluav taws xob ntawm lub installation PV, tiv thaiv kev puas tsuaj. Ntxiv rau cov khoom siv tiv thaiv qoj ib ce, LSP muaj cov khoom lag luam loj loj ua tiav cov txheej txheem tiv thaiv PV tiav suav nrog T1 (Chav I, Chav B), T1 + T2 (Chav I + II, Chav B + C), T2 (Chav Kawm II, Chav Kawm C) DC cia siab tiv thaiv cov cuab yeej.

Txheej txheem cej luam PV system

Txhawm rau kom paub tag nrho qhov system tiv thaiv kev tshaj tawm ntawm overvoltage surges thoob plaws hauv PV installation nws yog ib qho tseem ceeb kom xaiv qhov tseeb Surge Protection Device (SPD) rau txhua ntu ntawm cov kab ke hauv DC, AC thiab network-data network. Daim duab network thiab cov lus pab kom paub cov thaj chaw tseem ceeb ntawm kev tiv thaiv SPD.

Cov lus tibneeg nug (FAQs)

SPD ua haujlwm li cas?

Tus tiv thaiv hluav taws xob ua haujlwm los ntawm lub sijhawm "hloov" ntawm qhov qhib Circuit Court hom mus rau hauv hom uas tsis muaj kev cuam tshuam thiab ua kom lub zog hla mus rau hauv av, txwv cov kev hla mus rau qib kom ruaj ntseg hauv cov txheej txheem. Thaum qhov xwm txheej tshwm sim dhau ntawm tus tiv thaiv rov mus rau nws txoj kev qhib Circuit Court, npaj rau qhov kev tshwm sim tom ntej.

Vim li cas ib tus PV installation xav tau SPD?

Vim yog lub PV kev teeb tsa lub qhov thiab thaj chaw khaws khoom loj, ua rau muaj kev tawm tsam ncaj qha thiab tsis ncaj lub teeb hluav taws xob lossis cov kev hloov pauv ntawm overvoltage. SPD yuav tiv thaiv kev puas tsuaj rau kev teeb tsa, tiv thaiv cov nqi kho khoom kim rau cov khoom siv thiab cov nyiaj tau poob ntawm cov khoom ploj.

SPD twg yog qhov haum rau siv?

Qhov no nyob ntawm ntau yam nrog rau thaj chaw ntawm thaj chaw, cov cuab yeej siv uas tau raug pov thaiv thiab qhov tseem ceeb ntawm kev ua haujlwm. Kev teeb tsa ntawm lub ntiaj teb thiab nruab nrab ntawm cov coj kuj tseem ceeb heev. Thov xa peb email rau kev muag khoom [ntawm] lsp-international.com los sib tham txog koj cov kev xav tau.

Dab tsi yog ib qho MOV?

Hlau Hlau Oxide Varistor (MOV) yog cov hloov pauv kuj tsis xws li ua los ntawm cov thaiv ntawm zinc oxide nplej. Lawv ua zoo li semi-conductors, ib qho insulator hauv qab qhov hluav taws xob hluav taws xob thiab tsis tshua muaj nqi resistor siab dua nws.

Hauv kev ua hom, qhov MOV diverts thiab dissipates overvoltage hloov mus rau lub ntiaj teb. MOVs feem ntau txuas los ntawm kab txoj kab rau ntiaj teb. Lub thickness ntawm MOV txiav txim lub clamping voltage thiab lub cheeb txiav txim siab muaj peev xwm tam sim no.

SPD ntev npaum li cas?

Ntev npaum li cas MOV SPD kav ntev npaum li cas nyob ntawm qhov zaus thiab qhov loj ntawm cov teeb meem overvoltage. Qhov ntau dua qhov kev hloov pauv ntev dua, qhov ntau dua qhov kev xeb ntawm MOV.

SPD hloov kho yog dab tsi?

Modular SPD muaj cov qauv uas yuav hloov tau yam tsis tuaj yeem hloov tag nrho SPD chav, ua kev txij nkawm yooj yim thiab txo lub sijhawm nrog txo kev tiv thaiv. Cov qauv pub rau cov neeg ua haujlwm txo qis thiab tus nqi uas yuav tsum muaj rau kev pabcuam rau tus tiv thaiv.

Yuav hloov pauv SPD li cas tom kawg ntawm lub neej.

Eaton muaj peev xwm muab cov qauv ntsaws hloov kho rau txhua ntu ntawm kev lees paub. Cov modules hle nyob rau hauv thiab laim tawm tawm yam tsis tau yuam kom tag nrho lub cuab yeej yuav tsum tsis muaj kev nyab xeeb los ntawm kab ke.
