Kev tshuaj xyuas thiab kev daws teeb meem rau Rwb thaiv tsev txheej Cracking hauv Insulated Busbar rau EV Capacitor

Nyob rau hauv lub siab -voltage systems ntawm lub zog tshiab tsheb, lub rwb thaiv tsev kev ua tau zoo ntawm Insulated Busbar rau EV Capacitor ncaj qha cuam tshuam rau lub tsheb kev nyab xeeb. Rwb thaiv tsev txheej tawg yog ib qho kev phom sij raug; Yog tias tsis tau hais tam sim ntawd, nws tuaj yeem ua rau cov pa xau, luv luv, thiab tseem ua rau muaj kev cuam tshuam kev cuam tshuam lub tswb nrov hauv lub tsheb siab -voltage system, ua rau muaj kev hem thawj rau kev nyab xeeb ntawm kev tsav tsheb. Cov kws tshaj lij hauv kev lag luam taw qhia tias kev daws cov teeb meem no yuav tsum muaj kev sib xyaw ua ke ntawm kev kho thaum muaj xwm txheej ceev thiab hauv paus ua kom zoo. Tsuas yog los ntawm kev sib koom ua ke cov yam ntxwv ntawm BusBar Automotive cov khoom lag luam rau hauv cov kev daws teeb meem muaj peev xwm muaj kev nyab xeeb kev nyab xeeb yuav raug txo qis.

Rau kev txheeb xyuas cov txheej txheem rwb thaiv tsev tawg, kev tuav thiab kho thaum muaj xwm ceev yuav tsum ua raws li txoj cai ntawm kev nyab xeeb ua ntej, tshem tawm cov kev phom sij thib ob los ntawm kev ua haujlwm tsis raug. Thaum kuaj pom lub cev tawg lossis tawg tseem ceeb hauv txheej rwb thaiv tsev ntawm Insulated Bus Bar, cov khoom cuam tshuam yuav tsum raug kaw tam sim ntawd, thiab lub rooj sib txoos busbar ntawm tib qhov tshwj xeeb yuav tsum tau hloov los ntawm tus kws tshaj lij los xyuas kom meej tias qhov siab -voltage tiv thaiv kev ua tau zoo yog rov qab los. Rau kev puas tsuaj me me uas ua raws li cov cai tswj kev nyab xeeb, kev ntsuas kev kub ntxhov tuaj yeem ua tau: Ua ntej, ntxuav qhov chaw tawg kom huv si kom ntseeg tau tias qhov chaw qhuav, tsis muaj roj, thiab tsis muaj impurities; tom qab ntawd, siv high-voltage self- daim kab xev nplaum los yog daim kab xev insulating uas ua tau raws li lub tsheb siab-voltage qauv los txhawb kev tiv thaiv sab nraud; Tom ntej no, sau cov kab nrib pleb nrog kev ua haujlwm siab - kub resistant, siab - rwb thaiv tsev -lub zog silicone roj hmab los yog epoxy resin; Thaum kawg, nws yog ib qho tseem ceeb uas yuav tsum tau siv lub megohmmeter (insulation resistance tester) lossis siab -voltage tester kom paub meej tias qhov siab -voltage system rwb thaiv tsev tsis kam mus txog tus qauv ntawm 500Ω txog 1000Ω ib volt ua ntej rov siv dua.

Yog tias cov txheej txheej rwb thaiv tsev tawg tshwm sim hauv cov khoom siv los yog nquag, cov kev daws teeb meem tseem ceeb yuav tsum tau pom los ntawm kev hais txog qhov teeb meem ntawm cov qauv tsim thiab txheej txheem. Qhov no yog txoj hauv kev tseem ceeb rau kev txhim kho kev ntseeg siab ntawm EV Bus Bars. Hais txog kev hloov kho cov ntaub ntawv rwb thaiv tsev, PET zaj duab xis zoo tib yam tuaj yeem hloov nrog polyimide zaj duab xis (PI) lossis siab -cov ntaub ntawv muaj zog ntxiv, uas muaj cov khoom siv zoo dua qub, tawv tawv, thiab kev laus ua haujlwm. Nyob rau tib lub sijhawm, cov rwb thaiv tsev hauv zos ntxiv tuaj yeem ntxiv, ua haujlwm ob txoj kev rwb thaiv tsev los txhim kho cov txheej txheem rwb thaiv tsev tawg los ntawm cov khoom pom. Qhov kev ua kom zoo dua no kuj tseem siv tau rau cov khoom lag luam xws li Zaj Duab Xis Capacitor Busbar rau HEV / EV Tsav Tsav Tsheb.

Optimizing lub busbar qauv tsim thiab cov txheej txheem tsim khoom yog qhov tseem ceeb rau kev daws kev ntxhov siab ntau ntxiv -induced cracking. Thaum lub sij hawm fabrication ntawm lub laminated bar, ib tug saj zawg zog zaj duab xis coated nrog ib tug nplaum txheej yuav muab ntxiv rau cov qauv, uas yog feem ntau yuav kom muaj kev ncaj ncees thaum lub sij hawm thermal cycling. Cov ntaub nplaum txheej kuj yuav tsum tau optimized. Nyob rau ntawm bar khoov, nce lub vojvoog ntawm curvature txo cov neeg kho tshuab kev nyuaj siab concentration thiab tiv thaiv lub zos rwb thaiv tsev breakage. Thaum lub sij hawm ua, burrs ntawm M6 / M8 txiv ntseej thiab ntse hlau fab yuav tsum tau muab tshem tawm kom huv si tiv thaiv lawv los ntawm chob lub rwb thaiv tsev zaj duab xis. Qhov kub thiab txias tswj thaum lub sij hawm lamination ua kom cov nplaum sib faib thiab tiv thaiv micro- tawg hauv txheej rwb thaiv tsev. Qhov no muab cov lus qhia tseem ceeb rau kev tsim khoom thiab ua tiav ntawm Copper Busbar rau DC txuas EV Film Capacitor.

Tsis tas li ntawd, kev txhim kho kev ruaj ntseg ntawm kev ua haujlwm ib puag ncig tuaj yeem txo qhov tshwm sim ntawm rwb thaiv tsev tawg. Nws yog ib qho tsim nyog los ntxiv dag zog rau kev txhim kho siab - lub thawv tswj hluav taws xob thiab cov khoom siv hluav taws xob, txhim kho kev poob siab, thiab tiv thaiv busbar qaug zog tawg los ntawm kev vibrations thaum lub tsheb ua haujlwm. Nyob rau tib lub sijhawm, kev txhim kho cov cua sov dissipation nyob rau hauv cov neeg tsav tsheb thiab cov capacitor cheeb tsam tiv thaiv kev kub ntxhov ntau dhau los ntawm kev ua kom cov khoom siv hluav taws xob nrawm nrawm thiab txuas ntxiv lub neej kev pab cuam ntawm cov tsheb npav insulated. Cov kws tshaj lij hauv kev lag luam txiav txim siab tias cov khoom tawg busbar yuav tsum tau hloov ua ntej. Yog tias qhov tawg yog qhov dav, qhov ruaj khov ntawm cov txheej txheem tsim khoom thiab qhov siab - qhov kub thiab txias tsis kam ntawm cov ntaub ntawv rwb thaiv tsev siv yuav tsum tau tshawb xyuas kom zoo kom txo qis qhov tsis ua haujlwm ntawm nws qhov chaw.

Tam sim no, raws li lub zog tshiab tsheb hloov mus rau qhov siab- kawg thiab cov yam ntxwv ntse, cov kev cia siab rau cov khoom siv tsheb Bar tau nce tas li, thiab cov cuab yeej tiv thaiv hluav taws xob ntawm cov khoom tseem ceeb xws liInsulated Busbar rau EV Capacitorkuj tseem ua kom zoo tsis tu ncua. Nyob rau hauv lub neej yav tom ntej, kev lag luam yuav tsom mus rau kev hloov kho cov khoom siv, kev txhim kho cov txheej txheem, thiab kev txhim kho cov txheej txheem kom txuas ntxiv txhim kho kev nyab xeeb ntawm lub tsheb hluav taws xob siab -voltage systems, muab kev lees paub rau siab - kev txhim kho zoo ntawm kev lag luam tsheb tshiab.

Rau cov neeg nrhiav kev pab nrog kev xaiv kom zoo, kev daws teeb meem, thiab kev txhawb nqa rau cov txheej txheem rwb thaiv tsev tawg hauv Insulated Busbar rau EV Capacitor, thov hu rau peb. Peb yuav muab cov kev daws teeb meem tshaj lij los pab cov tuam txhab txo qis -voltage kev nyab xeeb phom sij thiab txhim kho kev ntseeg tau ntawm cov khoom.
