Cua sov mechanism thiab cov qauv countermeasures
Lub Joule cua sov (Q=I ² Rt) thiab faib inductance poob hauv kev xa hluav taws xob yog qhov laj thawj tseem ceeb rau kev txo qis hauv kev ua haujlwm. Intelligent laminated busbars daws teeb meem thermal los ntawm cov hauv paus hniav los ntawm kev siv lub laminated qauv ntawm alternating txheej ntawm conductive foils thiab insulating cov ntaub ntawv. Cov kab hluav taws xob zoo li qub tau txo qhov chaw siv hluav taws xob zoo vim muaj kev txwv hla - ntu ntu thiab cuam tshuam ntawm daim tawv nqaij; Lub multi- txheej thaum ua ke tsim ntawm lub stacked busbar ho nce qhov sib npaug ntawm tus ntoo khaub lig-sectional cheeb tsam thiab txo cov DC tsis kam.
Ib qho - txheej tuab yog tswj nyob rau hauv qhov tob ntawm daim tawv nqaij kom sib npaug sib npaug siab - zaus tam sim no thiab tsis txhob overheating. Cov qauv laminated nruj nreem ntawm Laminated tooj liab busbar tshem tawm cov hlau nplaum ntawm cov txheej txheem zoo thiab qhov tsis zoo, txo cov kev faib inductance kom tsawg dua 1/10 ntawm cov txheej txheem ib txwm muaj. Cov yam ntxwv uas tsis tshua muaj inductance no txo qis reactive zog poob thiab hloov surges, suppressing ntxiv cua sov los ntawm qhov chaw.
Optimization tsim ntawm tshav kub dissipation txoj kev
Lub tiaj tus qauv ntawm Intelligent laminated busbar muaj qhov zoo tshaj plaws ntawm thaj chaw / ntim piv, ua rau nws yooj yim mus txuas ncaj qha rau cov cua sov dissipation substrates lossis cov kua cua txias. Noj cov inverter ntawm lub zog tshiab tsheb ua piv txwv, tom qab laminated busbar yog sib koom ua ke rau hauv dej - cov phaj txias, qhov kub ua haujlwm tuaj yeem tswj tau li ntawm 60 degree, uas yog ntau tshaj 30℃qis dua cov kab hluav taws xob.
Kev xaiv ntawm cov ntaub ntawv rwb thaiv tsev ib txhij muaj kev cuam tshuam thermal kuj thiab kub dissipation efficiency. Polyimide zaj duab xis tuaj yeem tiv taus qhov kub siab txog 180 degree, thaum epoxy resin txheej muab kev tiv thaiv txhua yam thiab ntxiv cov cua kub cua. Lub laminated saj zawg zog busbar ua tiav cov cua kub sai sai thiab dissipation los ntawm ib qho kev sib koom ua ke ntawm "conduction rwb thaiv tsev kub dissipation".
Daim ntawv thov scenario pov thawj
Nyob rau hauv lub hwj chim roj teeb system ntawm lub zog tshiab tsheb nrog ntau pua kilowatts, efficiency ntawm lub hwj chim system yog txhim kho los ntawm 2% -3% tom qab hloov cables nrog Laminated inverter busbars. Cov yam ntxwv tsis tshua muaj siab ntawm laminated busbars txo Joule cua sov tiam, ncua lub neej ntawm cov khoom los ntawm ntau dua 15%.
Cov yam ntxwv qis inductance ntawm lub stacked busbar nyob rau hauv lub roj teeb module convergence thiab lub zog hloov dua siab tshiab txheej txheem ntawm lub zog cia fais fab chaw nres tsheb txo PCS hloov losses. Nyob rau tib lub sijhawm, kom tsis txhob muaj kev pheej hmoo ntawm rwb thaiv tsev laus los ntawm thermal tsub zuj zuj ntawm qhov chaw sib txuas, Laminated tooj liab tuav tau dhau los ua qhov kev sib txuas tseem ceeb rau siab - fais fab DC systems.
Nyob rau hauv kev sib txuas scenario ntawm industrial zaus converter fais fab modules, lub multi- txheej txheem ntawm lub stacked busbar zoo suppresses lub siab - zaus ntawm daim tawv nqaij. Los ntawm kev txo cov kev khiav hauj lwm kub ntawm lub module los ntawm 10℃-20 degree, lub stacked tsheb npav ho txhim kho lub sij hawm ntev kev cia siab ntawm lub hwj chim semiconductors.
Cov txheej txheem tseem ceeb tswj cov ntsiab lus
Kev ua haujlwm ntawm kev ua tau zoo yog nyob ntawm kev sib koom ua ke ntawm cov ntaub ntawv thiab cov txheej txheem. Cov txheej txheem ntawm Laminated tsheb npav rau kev sib txuas lus yog ua los ntawm siab -purity oxygen dawb tooj liab lossis 1060 aluminium alloy los xyuas kom meej qhov tsis muaj zog. Lub tshuab nqus tsev kub nias cov txheej txheem tshem tawm cov npuas npuas interlayer, tiv thaiv ib nrab tawm thiab ua kom thermal kuj, uas yog qhov txuas tseem ceeb ntawm kev tswj kom zoo rau cov laminated busbars.
Inter txheej kev sib raug zoo raug tswj kom tsis txhob muaj cua sov hauv zos los ntawm kev tsis sib xws tam sim no. Thaum lub sij hawm tsim qauv, nws yog ib qho tsim nyog los ua kom zoo dua cov txheej txheem thiab ib qho - txheej thickness ntawm Laminated tsheb npav bar rau siab tam sim no inverter raws li lub peev xwm nqa tam sim no thiab zaus yam ntxwv. Cov txheej txheem tsim kho ntawm laminated busbar yuav tsum sib npaug thermal, hluav taws xob, thiab cov khoom siv kho tshuab kom tau raws li qhov tshwj xeeb spatial txwv.
