Kev tshuaj xyuas ntawm qhov ua rau Laminated Inverter Busbars tsis ua haujlwm: Ntau yam cuam tshuam rau cov khoom siv ruaj khov

Hauv kev ua haujlwm ntawm inverter, Laminated Inverter Busbars ua lub luag haujlwm tseem ceeb ntawm lub zog xa hluav taws xob txuas txuas cov khoom tseem ceeb xws li capacitors thiab IGBT modules. Lawv kev ua haujlwm ruaj khov ncaj qha txiav txim siab lub inverter qhov kev ua tau zoo thiab kev nyab xeeb. Nws tau nkag siab tias qhov tsis ua haujlwm ntawm cov kab laminated tuaj yeem yooj yim ua rau muaj qhov tsis zoo hauv lub inverter, xws li overvoltage, overcurrent, lossis txawm tias luv luv Circuit Court, yog li cuam tshuam rau kev ua haujlwm ntawm tag nrho lub zog xa hluav taws xob. Yog li ntawd, kev tshawb nrhiav qhov ua rau tsis ua haujlwm thiab txo qhov kev pheej hmoo txhaum cai tau dhau los ua qhov tseem ceeb hauv kev lag luam hluav taws xob hluav taws xob. Qhov zoo thiab tsim qauv tsim nyog ntawm cov laminated busbars yog cov tseem ceeb cuam tshuam rau lawv lub neej kev pab cuam.

Cov kws tshaj lij kev lag luam taw qhia tias qhov tsis ua haujlwm ntawm inverter laminated busbars tsis yog tshwm sim los ntawm ib qho. Ntawm lawv, kev tiv thaiv kev laus thiab kev tawg yog qhov tseem ceeb tshaj plaws, uas feem ntau cuam tshuam nrog lub sijhawm ntev - ib puag ncig kev ua haujlwm thiab kev tsim khoom. Thaum inverters nyob rau hauv siab - qhov kub thiab txias rau lub sij hawm ntev, cov ntaub ntawv insulating xws li PET, PEN, thiab PI nyob rau hauv lub laminated bar yuav maj mam nkig thiab poob lawv insulating zog, nws thiaj li ua rau interlayer luv circuits. Yog tias cov txheej txheem tswj tsis tau zoo thaum lub sijhawm tsim khoom, yuav muaj qhov khoob lossis npuas hauv txheej rwb thaiv tsev. Nyob rau hauv qhov kev txiav txim siab ntawm - zaus thiab siab - qhov hluav taws xob qhov hluav taws xob, qhov tso tawm ib nrab (PD) yuav tshwm sim, uas yuav ua rau lub rwb thaiv tsev tawg tom qab ntev - lub sij hawm tsub zuj zuj. Tsis tas li ntawd, kev kho tsis raug ntawm cov npoo laminated thiab tsis txaus rwb thaiv tsev nyob deb (qhov deb deb) kuj tuaj yeem yooj yim ua rau interlayer ntug flashover tawg. Qhov teeb meem no yog qhov tshwj xeeb tshaj yog nyob rau hauv Laminated Busbars rau High -Temperature Applications.

Kev tsim khoom tsis zoo kuj yog ib qho tseem ceeb ua rau laminated busbar tsis ua hauj lwm, cuam tshuam ncaj qha rau cov qauv kev ruaj ntseg thiab rwb thaiv tsev kev ua tau zoo ntawm lub bar. Tsis sib xws lamination lossis delamination yog qhov ntau heev. Vim tsis muaj kev sib raug zoo ntawm cov tooj liab bar thiab txheej rwb thaiv tsev, huab cua accumulates ntawm cov ntsiab lus delamination, ua rau ib feem ntawm qhov hluav taws xob los yog hluav taws xob teb concentration, accelerating bar tsis ua hauj lwm. Yog hais tias av, noo noo, los yog hlau shavings nyob rau saum npoo ntawm lub tooj liab bar ua ntej lamination, nws yuav ua rau lub zos thinning ntawm lub rwb thaiv tsev txheej, txawm tsim conductive raws thiab tsim muaj peev xwm faults. Nyob rau tib lub sijhawm, yog tias cov burrs sab laug los ntawm cov txheej txheem tooj liab txiav tsis raug tshem tawm hauv lub sijhawm, lawv tuaj yeem tsoo cov yeeb yaj kiab rwb thaiv tsev, ncaj qha ua rau luv luv. Qhov no tso ntau dua xav tau ntawm kev tsim precision ntawm laminated tooj liab tuav.

Thermal expansion thiab mechanical stress puas tsuaj ntxiv rau qhov ua tsis tiav ntawm laminated busbar. Ntau zaus inverter pib- nce thiab kaw ua rau kev hloov pauv siab thiab qis. Vim qhov sib txawv coefficients ntawm thermal expansion ntawm tooj liab bar thiab rwb thaiv tsev txheej, rov qab thermal expansion thiab contraction tshwm sim, generating peeling kev nyuaj siab ntawm cov khaubncaws sab nraud povtseg. Qhov no accelerates qhov sib cais ntawm rwb thaiv tsev txheej los ntawm tooj liab bar, uas ua rau thermal cycling qaug zog puas. Yog hais tias lub inverter nyob rau hauv ib qho chaw uas muaj kev vibration tseem ceeb, nws yuav ntxiv exacerbate lub qaug zog tawg ntawm cov khoom uas twb puas lawm laminated. Qhov teeb meem no tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas muaj kev vibration tseem ceeb, xws li kev siv tsheb thiab cua zog, ua rau muaj kev sib tw rau kev ruaj ntseg ntawm Laminated Bus Bar rau Windmill Inverter IGBT I / O.

Overvoltage thiab transient voltage surges tau ncaj qha puncture lub laminated busbar rwb thaiv tsev, ua rau tam sim ntawd tsis ua hauj lwm. Thaum lub snubber Circuit Court tsis ua haujlwm lossis tsim tsis tau zoo, IGBT yuav tsim cov hluav taws xob siab heev ntawm qhov bar thaum lub sijhawm siab - zaus hloov. Yog tias cov spikes no dhau qhov kev tiv thaiv kev tiv thaiv kev tiv thaiv, lawv yuav tawg lub rwb thaiv tsev tam sim ntawd. Tsis tas li ntawd, DC input surges ua rau lub siab bar voltage ntau dhau tuaj yeem ua rau lub rwb thaiv tsev ncaj qha, uas ua rau lub bar tsis ua haujlwm. Qhov no tso cov kev cai nruj rau qhov kev xav ntawm laminated bar tsim.

Environmental chemical corrosion kuj tuaj yeem cuam tshuam rau kev pabcuam lub neej ntawm laminated busbars, ua rau tsis ncaj ncees lawm. Yog hais tias qhov chaw sab nraud yog ntub, los yog corrosive gases nkag mus rau hauv lub inverter, cov tooj liab yuav oxidize thiab undergo electrochemical corrosion, uas yuav erodes lub laminated rwb thaiv tsev txheej, maj mam txo nws cov rwb thaiv tsev kev ua tau zoo. Nyob rau tib lub sijhawm, qhov no tuaj yeem ua rau tsis ua haujlwm. Qhov teeb meem no yuav tsum tau ua tib zoo tiv thaiv nyob rau hauv sab nraum zoov photovoltaic thiab cua zog scenarios, thiab nws tso siab xav tau kev tiv thaiv tsim ntawm Laminated Bars rau Photovoltaic Inverters.

Cov kws tshaj lij kev lag luam tau sau tseg tias qhov ua tsis tiav ntawmLaminated Inverter Busbarsfeem ntau yog tshwm sim los ntawm ntau yam xws li thermal, hluav taws xob, thiab mechanical stress. Ntawm cov no, kev ruaj ntseg ntawm cov rwb thaiv tsev thiab qhov nruj ntawm cov txheej txheem tsim khoom yog qhov tseem ceeb rau kev txiav txim siab nws lub neej kev pab cuam. Raws li inverters txhim kho mus rau ntau zaus, qhov hluav taws xob ntau dua, thiab qhov me me, cov txheej txheem kev xav tau rau laminated bar fais fab kev daws teeb meem yuav nce ntxiv. Nyob rau hauv lub neej yav tom ntej, nws yuav tsim nyog los txo qhov tshwm sim ntawm laminated busbar tsis ua hauj lwm los ntawm optimizing tsim, txhim kho kev tsim precision, thiab ntxiv dag zog rau kev tiv thaiv kev ntsuas, thiaj li yuav muab kev txhawb zog rau kev ruaj ntseg ntawm inverters.

Yog tias koj xav tau kev sib tham ntawm Laminated Inverter Busbars tsis ua haujlwm daws teeb meem, kev tiv thaiv kev ua kom zoo, thiab kev daws teeb meem, thov koj xav tiv tauj peb rau kev txhawb nqa kev tshaj lij.
