Nrog rau kev nthuav dav thoob ntiaj teb sai ntawm lwm lub zog, lub hnub ci photovoltaic (PV) lub tshuab hluav taws xob tsim hluav taws xob tau nthuav dav rau hauv ntau yam kev lag luam thiab thaj chaw siv. Vim muaj kev cuam tshuam rau qhov chaw sab nraum zoov ntev ntev, cov PV complex arrays ntsib cov kev pheej hmoo xws li kub- cov teebmeem tshwm sim, thim rov qab tam sim no, thiab luv luv Circuit Court. Raws li cov khoom tiv thaiv tseem ceeb, PV fuses tiv thaiv hluav taws xob tsis raug, ua kom muaj kev nyab xeeb thiab txhim khu kev qha ntawm lub kaw lus. Kev tsim cov tshuab hluav taws xob tiv thaiv kev ruaj ntseg no yuav tsum tsis yog siab tshaj - kev ua tau zoo fuses tab sis kuj tseem hwm cov khoom siv hluav taws xob txuas ntxiv - xws li cov ntsia hlau - hom hlau clamp terminals - kom lav qhov kev sib kis tau ruaj khov thiab ruaj ntseg kev sib txuas hauv kev ua haujlwm tsis zoo.
Lub luag haujlwm tseem ceeb ntawm photovoltaic (PV) fuses nyob hauv kev tiv thaiv meej ntawm PV module hlua. Hauv kev teeb tsa, PV fuses feem ntau yog siv rau ntawm qhov tso zis ntawm txhua txoj hlua, nyob ze li sai tau rau lub thawv sib txuas lossis inverter. Thaum ib qho luv luv Circuit Court tshwm sim nyob rau hauv ib txoj hlua vim module puas los yog teeb meem thaiv, lub fuse reacts sai heev los cuam tshuam qhov txhaum tam sim no, yog li tiv thaiv tam sim no los ntawm kev puas tsuaj rau tag nrho cov hlua. Qhov kev sib cais ceev ceev no xav tau cov cuab yeej tshwj xeeb ntawm cov khoom siv hluav taws xob sib txuas; yog li ntawd, kev siv cov khoom sib xyaw ua ke- xws li ua ntej- sib dhos ntsia hlau hlau terminals- txo qis ntawm - qhov teeb meem kev teeb tsa thiab ua kom muaj kev ncaj ncees ntawm kev tiv thaiv Circuit Court.
Tshaj li kev tiv thaiv ib leeg cov hlua, PV fuses ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv PV sub-arrays. Thaum muaj ntau txoj hlua txuas nrog rau qhov sib luag los ua ib qho sub-array, luv luv hauv ib txoj hlua ua rau lwm txoj hlua ua haujlwm pub rau qhov rov qab loj heev rau hauv qhov chaw txhaum. Hauv qhov xwm txheej no, PV fuse tau nruab rau ntawm sub-array qhov sib txuas ntawm qhov sib txuas tau nrawm, cuam tshuam qhov luv luv -circuit tam sim no los ntawm ntws mus rau hauv cov hlua noj qab haus huv thiab yog li cais qhov txhaum. Ntawm cov siab no -tam sim no convergence cov ntsiab lus, cov khoom xws li tawb clamp ntsia hlau terminals los yog ua ntej - dhos ntsia hlau clamp terminals feem ntau yog ua hauj lwm los xyuas kom meej tias, nyob rau hauv siab - tam sim no surges, lub terminals tsis ua rau lwm yam hluav taws xob txhaum vim overheating los yog loosening.
Los ntawm qhov system- qhov kev xav dav dav, PV fuses muab kev tiv thaiv zoo rau tag nrho PV array thiab cov khoom siv hauv qab. Kev txhim kho fuses ntawm qhov sib txuas ntawm PV array conductors thiab daim ntawv thov Circuit Court conductors zoo tiv thaiv qhov tsis raug tam sim no los ntawm rov qab- noj los ntawm cov chaw xws li cov tsev txhab nyiaj roj teeb lossis cov phiajcim, yog li tiv thaiv cov array, cables, thiab cov tswj kev puas tsuaj. Tsis tas li ntawd, qhov siab -voltage DC xwm ntawm PV systems ua rau arc extinction nyuaj; tshwj xeeb PV fuses yog tsim los kom muaj kev nyab xeeb cuam tshuam rau hauv cov cheeb tsam no, tiv thaiv kev tsim cov arcs txaus ntshai. Ntawm cov khoom siv hluav taws xob tseem ceeb no, kev siv ua ntej - haum cov ntsia hlau davhlau ya nyob twg clamps lossis cov ntsia hlau txuas txuas txuas txuas txuas ntxiv txhim kho kev sib dhos ua haujlwm hauv cov khoom xa tawm thiab ua kom ntev - lub sijhawm ua haujlwm hluav taws xob muaj kev nyab xeeb.
Hauv kev ua haujlwm ntev -lub sijhawm ua haujlwm, kev saib xyuas, thiab tshuaj xyuas cov tshuab hluav taws xob photovoltaic (PV), kev ntseeg siab ntawm kev sib txuas hluav taws xob yog txuas ncaj qha rau lub zog tsim hluav taws xob thiab kev nyab xeeb hluav taws ntawm tag nrho cov nroj tsuag. Kev sib cuag tsis zoo tam sim no lossis kev sib cuag tsis zoo tuaj yeem ua rau cov cables thiab cov khoom sib txuas ua kom sov, ua rau cov txheej txheem rwb thaiv tsev puas tsuaj thiab tsim teeb meem hluav taws. Yog li ntawd, cov khoom xws li galvanized steel ntsia hlau davhlau ya nyob twg clamps los yog zinc alloy ntsia hlau hlau terminals- uas muaj kev tiv thaiv corrosion zoo heev- feem ntau yog xaiv rau qhov hnyav sab nraum zoov kom tiv taus cua ntev, tshav ntuj, thiab ntsev tsuag. Lub caij no, nyob rau hauv cov thawv sib txuas uas yuav tsum tau ua haujlwm ntau zaus lossis yuav tsum ua haujlwm siab tam sim no, steel tawb ntsia hlau davhlau ya nyob twg blocks ua qhov kev xaiv zoo tshaj plaws rau kev ua haujlwm ruaj khov, ua tsaug rau lawv cov kev coj ua zoo tshaj thiab cov cuab yeej clamping quab yuam.
Nyob rau hauv ntau txoj kev tswj hluav taws xob thiab kev tiv thaiv circuits, PV fuses feem ntau ua haujlwm ua ke nrog lwm cov khoom siv tiv thaiv. Circuit breaker ntsia hlau clamp terminals feem ntau ua hauj lwm ntawm inverter outputs los yog nyob rau hauv lub ntsiab tis panels los pab txhawb Circuit Court cais thiab rov pib dua. Nyob rau hauv contactor los yog relay tswj circuits, contactor ntsia hlau hlau clamp terminals xyuas kom meej cov kis tau tus mob ntawm kev tswj cov teeb liab. Hais txog kev teeb tsa ntawm cov fuses lawv tus kheej, cov fuse yas dhos ntsia hlau clamp terminals muab tsis tau tsuas yog kev txhawb nqa lub cev muaj zog tab sis kuj ua kom muaj kev nyab xeeb thiab txhim khu kev cuam tshuam ntawm kev cuam tshuam tsis zoo thaum lub sijhawm fuse ua haujlwm.
Hauv cov ntsiab lus, photovoltaic fuses ua lub luag haujlwm tseem ceeb hauv kev muab kev tiv thaiv overcurrent thiab kev sib cais txhaum hauv cov tshuab photovoltaic. Txawm hais tias siv cov ntsia hlau- actuated tawb clamps los yog txhais tes yooj yim -tightened terminal blocks, cov precision hluav taws xob kev twb kev txuas Cheebtsam ntxiv siab -kev ua tau zoo photovoltaic fuses. Xaiv cov cuab yeej tiv thaiv tsim nyog thiab cov kev daws teeb meem sib txuas raws li kev thov tshwj xeeb yog qhov tseem ceeb los ua kom lub sijhawm ntev - kev nyab xeeb thiab kev ua haujlwm tau zoo ntawm tag nrho cov tshuab photovoltaic nyob rau hauv kev ua haujlwm nyuaj.
Yog tias koj muaj lus nug txog kev tiv thaiv overcurrent kev daws teeb meem rau cov tshuab photovoltaic, xaiv fuse, lossis kev hloov kho ntawmClamp-Hom Screw Terminal rau Circuit Court Cheebtsam, thov koj xav tiv tauj peb pab pawg kws tshaj lij engineering; peb npaj txhij los muab kev txhawb nqa thiab kev daws teeb meem.
