Lub thawv sib txuas yog ib feem tseem ceeb ntawm lub chaw nres tsheb photovoltaic, thiab cov tshuaj tiv thaiv thim rov qab yog qhov tsis tseem ceeb ntawm lub thawv sib txuas, yog li yuav xaiv li cas los tiv thaiv thim rov qab diode yog qhov txuas tseem ceeb heev rau tsis tsuas yog lub thawv sib txuas tab sis kuj photovoltaic fais fab chaw nres tsheb.
Kev sib xyaw ntawm lub thawv sib xyaw
Cov khoom lag luam ib txwm muaj nyob hauv cov chaw tsim khoom siv hluav taws xob loj loj suav nrog cov thawv sib txuas photovoltaic nrog 6, 8, 10, 12, 16 Circuit thiab lwm yam kev qhia tshwj xeeb. Nws tuaj yeem hloov kho raws li cov neeg siv khoom xav tau, tus lej ntawm cov loops tsis txwv, hloov pauv tau yooj yim, feem ntau tsim los ntawm cov hauv qab no
Lub cev lub thawv
Lub thawv ntawv lub cev feem ntau yog ua los ntawm cov hlau phaj txau yas, hlau tsis muaj hlau, yas plastics thiab lwm yam khoom siv, zoo nkauj tsos, muaj zog thiab ruaj khov, yooj yim thiab yooj yim rau nruab, nrog qib tiv thaiv IP 54 lossis siab dua, tsis muaj dej thiab tsis muaj hmoov av, thiab ua tau raws li qhov xav tau ntawm kev siv sab nraum zoov mus sij hawm ntev.
DC lub tshuab hluav taws xob
Lub tshuab hluav taws xob DC yog lub tshuab tswj cov khoom tso tawm ntawm txhua lub thawv sib txuas, uas feem ntau yog siv rau kev qhib/kaw ntawm Circuit Court. Nws qhov ua haujlwm siab yog siab li DC1000V. Txij li lub zog tsim los ntawm lub hnub ci module yog ncaj qha tam sim no, nws yog ib qho yooj yim ua rau arcing thaum lub Circuit Court tawg. Yog li ntawd, qhov kub thiab qhov siab derating coefficient yuav tsum tau txiav txim siab tag nrho thaum xaiv tus qauv, thiab tshwj xeeb photovoltaic DC Circuit Court breaker yuav tsum raug xaiv.
DC lub fuse
Thaum tus qauv rov qab los tam sim no, qhov tshwj xeeb photovoltaic DC fuse tuaj yeem txiav tawm txoj hlua tsis raug hauv lub sijhawm. Qhov ntsuas ua haujlwm voltage yog DC1000V, thiab ntsuas tam sim no feem ntau yog 15A (crystalline silicon module). Cov qauv ua piv txwv yog SP10M10-1000 SP10M12-1000 SP10M15-1000.
DC fuse siv nyob rau hauv photovoltaic modules yog qhov fuse tshwj xeeb tsim rau cov tshuab photovoltaic (qhia qhov loj me 10 hli× 38 hli), uas tau teeb tsa nrog lub hauv paus tshwj xeeb uas tiv thaiv kom tsis txhob rov qab los tam sim no ntawm cov hlua thiab hlawv cov qauv. Thaum cov dej ntws rov los tam sim no tshwm sim, DC fuse tshem tawm txoj hlua tsis raug los ntawm kev ua haujlwm tsis muaj cuam tshuam rau lwm txoj haujlwm ua haujlwm ib txwm muaj, thiab tuaj yeem tiv thaiv kev nyab xeeb ntawm txoj hlua photovoltaic thiab nws cov neeg ua haujlwm los ntawm kev hem thawj ntawm kev thim rov qab.
Anti-thim rov qab diode
Lub luag haujlwm ntawm diode hauv lub thawv sib txuas sib txawv ntawm qhov diode hauv lub thawv sib txuas ua ke. Lub diode hauv lub thawv sib txuas ua ke feem ntau muab lub freewheeling channel thaum lub roj teeb raug thaiv, thiab cov diode hauv lub thawv sib txuas feem ntau tiv thaiv kev sib kis tam sim no ntawm cov hlua. Cov qauv ua piv txwv suav nrog Hangzhou Guojing’s MD300A1600V thiab GJMH200A1600V
Hauv kev ywj pheej tsim hluav taws xob tsim hluav taws xob tsim hluav taws xob, qee lub tshuab hluav taws xob photovoltaic tau txuas nrog lub zog tiv thaiv thim rov qab, uas yog, thaum tus tswj hwm muaj lub luag haujlwm tiv thaiv rov qab, cov khoom siv tsis tas yuav txuas nrog lub diode. Kev tiv thaiv rov qab them nqi diode muaj qhov poob qis rau pem hauv ntej, thiab nws yuav siv qee qhov nqi zog thaum txuas nrog hauv kab hauv Circuit Court. Feem ntau, qhov hluav taws xob poob ntawm silicon rectifier diodes siv yog kwv yees li 0.7V, thiab lub raj hluav taws xob siab tuaj yeem ncav cuag 1 ~ 20.3V, tab sis nws tiv taus qhov hluav taws xob thiab lub zog me me, haum rau cov ntawv thov qis.
Vim yog qhov txwv ntawm IP65 qhov ntsuas ntawm lub thawv sib txuas, nws feem ntau yooj yim dua rau xaiv hom modular. Cov xwm txheej tseem ceeb rau kev xaiv cov tshuaj tiv thaiv rov qab diode module yog qhov poob siab, tsis muaj cua sov tiv taus, thiab muaj peev xwm ua kom muaj cua sov caij tsheb kauj vab.
