Qhov tseem ceeb ntawm photovoltaic diodes hauv hnub ci zog tsim

Nyob rau hauv lub square array ntawm lub hnub ci cell, diode yog ib qho khoom siv heev, feem ntau siv diode yog silicon rectifier diode, nyob rau hauv kev xaiv ntawm specifications kom txuag tsis tau, tiv thaiv kev puas tsuaj.Feem ntau, qhov rov qab ncov qhov hluav taws xob tawg thiab qhov siab tshaj plaws ua haujlwm tam sim no yuav tsum yog ntau tshaj 2 npaug ntawm qhov siab tshaj plaws kev khiav hauj lwm voltage thiab kev khiav hauj lwm tam sim no.Muaj ob hom diodes hauv photovoltaic systems.

Diode rau kev tiv thaiv rov qab them nyiaj (tiv thaiv rov qab tam sim no)

Ib qho ntawm cov haujlwm ntawm Diode rau kev tiv thaiv kev tiv thaiv kev thim rov qab (tiv thaiv kev them rov qab) yog tiv thaiv tam sim no ntawm lub hnub ci ntawm lub hnub ci ntawm lub hnub ci rov qab mus rau lub hnub ci cell lossis square array thaum lub hnub ci cell lossis square array tsis tsim hluav taws xob. lub luag hauj lwm yog nyob rau hauv lub roj teeb array, los tiv thaiv tam sim no ntawm cov ceg ntawm lub array thim rov qab.Qhov no yog vim hais tias cov zis voltage ntawm txhua ceg nyob rau hauv series tsis tuaj yeem sib npaug kiag li, yeej ib txwm muaj qhov sib txawv ntawm qhov siab thiab qis voltage ntawm txhua ceg, los yog cov zis voltage ntawm ib ceg yog qis dua vim yog qhov txhaum ntawm ib ceg, shading. , thiab lwm yam , tam sim no ntawm high voltage ceg yuav ntws mus rau qhov tsawg voltage ceg thiab txawm txo tag nrho cov zis voltage ntawm lub square array.Qhov tshwm sim no tuaj yeem zam tau los ntawm kev sib txuas los tiv thaiv rov qab-filling diodes hauv koob hauv txhua ceg.

Slocable'sAnti-Reverse Diodemuaj qhov ntsuas hluav taws xob ntawm 1600V, qhov hluav taws xob cais hluav taws xob txog li 3100V ntawm cov nti thiab cov substrate, iav passivated nti soldered, zoo heev kub yam ntxwv thiab lub zog cycling muaj peev xwm, thiab silicon carbide diodes, dua li cov diode zoo tib yam zog noj ntawm ntau tshaj 15 % .Rated tam sim no mus txog 55 A. Yog tias koj lub cev muaj qhov ntsuas tam sim no ntau dua 12A, qhov no diode raug pom zoo los tiv thaiv koj cov khoom.

Bypass diode

Thaum ntau lub hnub ci cell modules txuas nrog hauv series los tsim ib ceg ntawm cov xov tooj ntawm tes lossis cov xov tooj ntawm tes, ib qho (lossis ob lossis peb) diodes yuav tsum tau txuas nrog rov qab ua ke ntawm qhov zoo thiab qhov tsis zoo tso tawm terminals ntawm txhua lub vaj huam sib luag, qhov no diode. , uas yog kev cob cog rua nyob rau hauv parallel ntawm ob kawg ntawm lub Assembly, hu ua ib tug bypass diode.

Lub luag hauj lwm ntawm bypass diodes yog los tiv thaiv ib feem los yog ib feem ntawm cov khoom nyob rau hauv lub square array los ntawm kev ntxoov ntxoo los yog nres los ntawm lub hwj chim tiam nyob rau hauv qhov kev tshwm sim ntawm ib tug tsis ua hauj lwm, lub series tam sim no ntawm lub Cheebtsam bypasses lub faulty Cheebtsam thiab ntws los ntawm lub diode. cuam ​​tshuam rau lub zog tsim ntawm lwm cov khoom ib txwm muaj, thaum tseem tiv thaiv cov khoom hla dhau los ntawm kev siab dua rau pem hauv ntej lossis kev puas tsuaj vim“Cov nyhuv kub”cua sov.

Bypass diodes feem ntau ntsia ncaj qha rau hauv lub thawv sib txuas, raws li qhov loj ntawm cov khoom siv hluav taws xob thiab cov roj teeb, kev teeb tsa ntawm 1 ~ 3 diodes.

Lub by-pass diode tsis tas yuav tsum tau nyob rau hauv txhua qhov teeb meem, thaum lub Cheebtsam yog siv nyob rau hauv ib leeg los yog nyob rau hauv parallel, nws tsis yog tsim nyog los txuas lub diode.Rau ob peb yam hauv koob thiab qhov chaw ua haujlwm zoo, koj tuaj yeem xav txog kev siv bypass diodes.
