laminated busbar nyob rau hauv High Power Converter: Xaiv Phau Ntawv Qhia thiab Daim Ntawv Thov Kev Ntsuam Xyuas

Lub laminated busbar yog cov khoom siv hluav taws xob sib xyaw siv hauv high -voltage converters. Los ntawm kev sib hloov laminating ntau txheej ntawm conductive tooj liab tuav thiab cov ntaub ntawv insulating, ib txoj kev faib nrog tsawg inductance, siab capacitance, thiab loj tam sim no nqa peev xwm yog tsim. Nyob rau hauv high-power density daim ntawv thov scenarios, laminated busbars yuav txo tau lub voj stray inductance, txo switching overvoltage, thiab txhim kho kev ntseeg siab ntawm lub hwj chim modules thiab system efficiency. Nyob rau hauv txoj kev tsheb ciav hlau traction converters, Composite Busbar rau Tsheb ciav hlau fais fab mov Plaub-quadrant Fais fab Module assumes lub luag hauj lwm tseem ceeb ntawm zoo txuas lub rectifier thiab inverter units. Nws cov qauv laminated zoo suppresses voltage spikes nyob rau hauv plaub -quadrant kev khiav hauj lwm hom thiab xyuas kom meej cov kev khiav hauj lwm zoo ntawm lub tsheb ciav hlau traction system. Hauv kev sib txuas lus fais fab kev faib tawm, Laminated Bus Bar rau Telecom Fais Fab Kev faib tawm yog kev koom ua ke rau hauv -48V DC lub zog xa hluav taws xob, hloov cov khoom siv hluav taws xob ib txwm siv nrog cov qauv tsim compact, uas tsis tsuas yog txo cov kab poob, tab sis kuj txhim kho qhov chaw siv thiab cua sov hauv lub txee. Nyob rau hauv theem teeb pom kev zoo tswj qhov system, Laminated Bus Bar rau PDA Assembly A Hit In Stage Lighting Systems cia siab rau nws txoj kev ntseeg siab thiab cov lus teb ceev ceev tam sim no muaj peev xwm ua tau raws li qhov xav tau nruj rau cov khoom siv hluav taws xob faib khoom ntawm cov khoom siv teeb pom kev zoo rau kev pib, nres thiab dimming.

Cov khoom siv ntawm lub laminated busbar feem ntau suav nrog peb ntu: cov khoom siv txheej txheej, cov txheej txheem insulating thiab cov khoom siv kho mob. Kev xaiv cov ntaub ntawv ncaj qha txiav txim siab txog lub peev xwm nqa tam sim no, kev ua haujlwm rwb thaiv tsev, qib kub tsis kam thiab ib puag ncig adaptability ntawm cov khoom. Cov khoom siv hluav taws xob feem ntau yog ua los ntawm siab -conductivity tooj liab (T2 lossis TU1 qib), uas nws cov conductivity tsis tsawg dua 98% IACS, thiab cov thickness ntau yog feem ntau 0.8mm txog 6.0mm, uas yog xaiv raws li qhov ntsuas tam sim no. Rau cov ntawv thov kev tsheb ciav hlau xws li Composite Busbar rau Tsheb ciav hlau Fais Fab Plaub -quadrant Fais Fab Module, vim yog lub sijhawm ntev - raug rau kev co thiab kev cuam tshuam ib puag ncig, qhov elongation ntawm cov ntaub ntawv tooj liab yuav tsum muaj ntau dua 30% kom ntseeg tau tias cov pob txha tawg tsis tshwm sim hauv kev ntxhov siab.

Rau cov khoom me me hauv Laminated Bus Bar rau Compact IGBT DC Lub Hwj Chim, cov txheej txheem sib xyaw ua ke nrog cov txheej txheem txhuas thiab tooj liab plating yog qee zaum siv los txo qhov hnyav thaum tuav lub ntsej muag solderability. Cov khoom siv rwb thaiv tsev feem ntau siv cov nplaim hluav taws xob- cov yeeb yaj kiab polyester (PET), polyimide zaj duab xis (PI) lossis epoxy iav ntaub (FR-4). Polyimide zaj duab xis muaj qhov kub thiab txias tsis kam thiab tuaj yeem ua haujlwm tau ntev hauv thaj tsam ntawm -40℃rau +150℃. Nws yog qhov tsim nyog rau qhov kub thiab txias ntau qhov chaw ua haujlwm uas yuav raug ntsib hauv kev siv tsheb xws li DC thiab AC Laminated Bus Bar rau Fork Lift Truck. Rau Laminated Bus Bar rau Kev Tshawb Fawb Kev Kho Mob, cov khoom siv rwb thaiv tsev kuj xav tau kom ua tau raws li cov khoom siv hluav taws xob tsawg thiab cov hluav taws xob tiv thaiv kom ua raws li cov qauv kev nyab xeeb ntawm kev kho mob.

Kev tsim cov txheej txheem ntawm laminated busbars suav nrog ntau qhov txuas xws li stamping, rwb thaiv tsev lamination, thermal lamination, khoov thiab kho qhov chaw. Qib ntawm cov txheej txheem tswj nyob rau hauv txhua qhov txuas ncaj qha txiav txim siab qhov kev ua tau zoo ntawm hluav taws xob thiab kev ntseeg siab ntawm cov khoom siv. Nyob rau hauv cov txheej txheem stamping thiab sib sau, lub conductive tooj liab bar yog precision xuas nrig ntaus los tsim cov txheej contour thiab sab hauv kev sib txuas qhov. Cov seem punched yuav tsum du thiab burr -dawb. Rau lub connector mating nto los yog lub hwj chim module tus pin tiv tauj nto, burr qhov siab yuav tsum tau tswj hauv qab no 0.05mm kom tsis txhob muaj kev sib cuag tsis zoo los yog ib nrab paug. Rau cov khoom loj - loj xws li Composite Busbar rau Tsheb ciav hlau Fais Fab Plaub -quadrant Fais Fab Module, kev ntxhov siab yuav tsum tau ua tom qab stamping kom tshem tawm cov kev ntxhov siab sab hauv uas tsim los ntawm kev ua haujlwm txias thiab tiv thaiv warping thaum kub nias tom ntej. Rwb thaiv tsev lamination yog txheej txheem tseem ceeb ntawm laminated busbars. Raws li tus tsim stacking ib ntus, conductive tooj liab tuav thiab insulating films yog alternated stacked. Cov yeeb yaj kiab insulating feem ntau yog ua ntej-coated nrog kub yaj nplaum rau ntawm ib lossis ob sab kom ua tiav kev sib raug zoo thaum lub sijhawm kub nias.

Qhov tseeb stacking yuav tsum tau hais tias qhov sib txawv ntawm qhov sib txawv ntawm txhua txheej tsis pub tshaj ± 0.1mm kom paub meej tias qhov sib txuas ntawm qhov sib raug zoo ntawm cov txheej tooj liab sib txawv. Cov txheej txheem kub - nias yog ua nyob rau hauv lub tshuab nqus tsev kub - pressing tshuab. Cov cua kub kub, siab thiab tuav lub sij hawm yuav tsum tau teem kom raug raws li cov thermosetting khoom ntawm insulating zaj duab xis. Rau Laminated Bus Bar rau Kev Tshawb Fawb Kev Kho Mob, cov txheej txheem kub -nias kuj yuav tsum tau ua nyob rau hauv ib qho chaw huv si kom tsis txhob muaj cov khoom sib xyaw ua ke los ntawm kev ua rau txo qis hauv rwb thaiv tsev tiv thaiv hluav taws xob. Tom qab kub nias, lub laminated busbar yuav tsum tau txais kev rwb thaiv tsev tiv thaiv qhov ntsuas hluav taws xob thiab kev kuaj ib nrab los xyuas qhov tseeb ntawm cov rwb thaiv tsev interlayer. Cov txheej txheem dabtsi yog khoov yog siv los ua cov txheej txheem ca laminated busbar rau hauv peb- qhov loj me uas haum rau qhov chaw teeb tsa. Lub vojvoog dabtsi yog khoov yuav tsum tau tswj nruj me ntsis thaum khoov kom tsis txhob muaj cov tooj liab sab nraud yog nyias dhau vim yog ncab lossis sab hauv tooj liab bar tau wrinkled vim compression. Cov txheej rwb thaiv tsev ntawm qhov khoov yuav tsum tsis txhob tawg lossis tev.

Daim ntawv thov ntawm laminated busbars tau ntev txij li dhau los ntawm ib qho kev hloov pauv zaus, thiab tau nkag mus rau hauv ntau yam siab - fais fab xwm txheej:

Nyob rau hauv kev lag luam zaus converters, lub laminated tsheb npav bar rau qhov sib txawv zaus tsav txuas lub rectifier choj, capacitors, thiab inverter module, kom ntseeg tau tias lub cev muaj zog tsav ua haujlwm. Rau cov mining ib puag ncig nrog kev tawg siab heev- cov ntaub ntawv pov thawj, lub siab -laminated busbar rau voltage tawg- cov ntaub ntawv pov thawj inverters muab kev ruaj ntseg tsis tseem ceeb. Nyob rau hauv lub tshav pob ntawm lub zog tshiab tsheb, lub siab thermal conductivity metallized zaj duab xis capacitor busbar rau EV tswj systems yog ib tug tseem ceeb ntawm lub cev muaj zog maub los, lub luag hauj lwm rau zoo hloov roj teeb lub zog rau lub inverter. Ib yam li ntawd, nyob rau hauv txoj kev tsheb ciav hlau, lub inverter tsheb npav bar rau kev tsheb ciav hlau thiab kev thauj mus los locomotive fais fab tsheb npav bar tiv taus tam sim no loj heev surges thiab mechanical vibrations; lawv txoj kev ntseeg tau ncaj qha cuam tshuam rau kev nyab xeeb ntawm cov tsheb ciav hlau.

Nrog rau kev loj hlob ntawm kev siv hluav taws xob tawg, lub zog ceev ntawm cov khoom siv hluav taws xob rau cov khoom siv hluav taws xob tau dhau los ua nruj. Laminated busbars rau supercomputer circuit boards lossis backplanes thiab rau internet router backplanes, nrog lawv cov compact loj thiab tsis tshua muaj impedance, daws cov cua kub dissipation thiab cabling cov nyom nyob rau hauv siab - ceev racks. Tsis tas li ntawd, laminated busbars rau cellular base chaw nres tsheb fais fab faib kuj ua lub luag haujlwm tseem ceeb hauv 5G xa mus.Hauv cov khoom siv hluav taws xob tsis cuam tshuam (UPS), lub tshuab hluav taws xob tsis cuam tshuam tsis cuam tshuam rau lub tshuab hluav taws xob busbar ua kom xoom-latency thiab muaj kev ntseeg siab thaum lub zog hloov. Hauv cov khoom siv kho mob siab - kawg, laminated busbars rau cov cuab yeej ntsuas kev kho mob, nrog rau lawv cov suab nrov qis thiab ruaj khov, lav cov duab meej.

Tau ntsib cov kev sib tw nruj ntawm qhov qis inductance thiab lub zog siab ceev hauv siab - lub zog hloov pauv, peb tau cog lus los muab kev qhia rau kojlaminated busbar hauv High Power Converter, los ntawm cov txheej txheem optimization mus rau thermal tswj. Thov koj xav tiv tauj peb rau kev txhawb nqa kev tshaj lij.
