Technical article|Laminated tooj liab busbar rwb thaiv tsev cov ntaub ntawv - Kev sib tham luv luv ntawm cov rwb thaiv tsev hloov tau yooj yim thiab nruj thiab lawv qhov tsis muaj

Tus neeg xyuas pib rwb thaiv tsev ntawm Laminated saj zawg zog busbar cia siab rau cov ntaub ntawv rwb thaiv tsev hloov tau yooj yim, uas yog nruj nreem khi rau tus neeg xyuas pib los ntawm cov txheej txheem nplaum lamination, tsim kev tiv thaiv ntawm ntug ntawm tus neeg xyuas pib. Txawm hais tias nyob rau hauv huab cua hnyav, kev rwb thaiv tsev tsis ua haujlwm tuaj yeem zam tau, thiab nws cov nplaim hluav taws tuaj yeem txo qhov kev pheej hmoo ntawm kev tawg ntawm busbar. Cov khoom siv hluav taws xob hloov tau yooj yim tshaj plaws tam sim no yog polyester (PET), uas muaj nyob rau hauv pob tshab lossis dawb specifications thiab tau dhau los ua qhov kev xaiv zoo tshaj plaws rau feem ntau cov ntawv thov busbar vim nws qhov kev ua tau zoo.

Cov khoom siv PET muaj qhov ntsuas kub ntawm 105 ° C thiab tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev ntawm qhov kub no; Nws elongation tus nqi siab tshaj 100%, thiab nws tsis yog ib qho yooj yim los tsim kua muag los yog nyias nyob rau hauv cov txheej txheem ntawm Laminated tooj liab tuav xws li khoov thiab conductor ntug wrapping. Nws kuj tseem tuaj yeem tswj xyuas cov duab ntawm tus neeg xyuas pib txawm tias tom qab tshaj qhov kub hloov pauv iav; Muab ntau yam thicknesses xws li 50 μ m, 125 μ m, 250 μ m, 350 μ m, thiab lwm yam., sib npaug kev lag luam thiab hloov tau; Nyob rau tib lub sijhawm, nws muaj qhov zoo tshaj plaws txheeb ze txheeb ze taug qab qhov ntsuas (CTI), uas tuaj yeem ua kom luv luv ntawm kev nkag mus thiab ua tau raws li UL94-V0 nplaim hluav taws kub retardant thaum ua tiav qhov thinning.

Lwm hom kev ua haujlwm siab -cov khoom siv rwb thaiv tsev hloov tau yooj yim yog polyimide (PI), uas yog xim av lossis xim dub thiab tsom rau qhov kub thiab txias. Nws tus txheeb ze ntsuas kub (RTI) tshaj 200℃C, ua rau nws haum rau vuam busbar Cheebtsam thiab zam kev puas tsuaj rau rwb thaiv tsev thaum cua sov. Txawm li cas los xij, PI cov khoom muaj zog dua, tsis muaj cov ntsiab lus ntawm kev ntxhov siab, tsis zoo ntawm qhov chaw, thiab tsuas yog tsim rau cov ntawv thov hauv qab 600V. Tus qauv thickness tsuas yog 25 μ m rau 50 μ m, uas yog kim tshaj tus tsiaj. Yog li ntawd, nws tsuas yog siv rau hauv qhov tshwj xeeb siab -kub xav tau xwm txheej.

Kev rwb thaiv tsev yooj yooj yim thiab cov rwb thaiv tsev nruj ua haujlwm sib txawv hauv Laminated tooj liab busbars, thiab lawv cov kev xaiv nyob ntawm qhov voltage thiab rwb thaiv tsev cov cai ntawm daim ntawv thov scenario. Saj zawg zog rwb thaiv tsev yog tsuas yog siv rau kev tiv thaiv rwb thaiv tsev ntawm tus neeg xyuas pib lub cev thiab yog lub hauv paus tseem ceeb ntawm lub hauv paus stacked busbar. Nws tuaj yeem tsim cov khoom siv hluav taws xob zoo tshaj plaws ntawm cov haujlwm tseem ceeb xws li cov npoo ntawm tus neeg xyuas pib thiab vias, ua kom muaj kev ntseeg tau ntawm cov khoom siv hluav taws xob ntawm tus kheej.

Rigid rwb thaiv tsev yog siv rau kev sib cais ntawm cov khoom tiav ntawm Laminated busbar rau kev sib txuas lus, thiab nws cov thickness yog ncaj qha txiav txim siab los ntawm qhov system khiav hauj lwm voltage. Lub hom phiaj tseem ceeb yog txhawm rau txhim kho qhov tseem ceeb ntawm kev faib hluav taws xob thiab ua tau raws li qhov yuav tsum tau muaj ntawm kev tiv thaiv ib feem. Cov txheej txheem kev lag luam yog txhawm rau txhim kho cov rwb thaiv tsev nruj nrog lub thickness ntawm 1mm ib kilovolt voltage. Cov khoom siv feem ntau yog iav fiber reinforced polyester, nrog lub thickness ntawm 1 hli mus rau 6 hli. Piv txwv li, ib tug 3000V DC nyiaj siv ua haujlwm kab nrog lub siab tshaj plaws kev khiav hauj lwm voltage tsis tshaj 4800V yuav tsum tau siv 5 hli tuab rigid rwb thaiv tsev cov ntaub ntawv. Qhov siab dua qhov voltage, lub thicker qhov yuav tsum tau nruj rwb thaiv tsev thickness.

Cov ntsiab lus tseem ceeb rau kev ntsuas qhov ua tau zoo ntawm Laminated inverter busbars rwb thaiv tsev cov ntaub ntawv feem ntau suav nrog cov txheeb ze qhov ntsuas kub (RTI), txheeb ze qhov ntsuas qhov ntsuas (CTI), thiab elongation, uas sib haum rau cov khoom siv hluav taws xob tiv thaiv lub neej, hluav taws xob hluav taws xob, thiab kev sib raug zoo ntawm cov khoom siv.

RTI tau txhais raws li UL 746 tus qauv raws li qhov siab tshaj plaws kev khiav hauj lwm kub ntawm cov ntaub ntawv rwb thaiv tsev, tshwj xeeb tshaj yog qhov kub ntawm cov neeg kho tshuab elongation thiab hluav taws xob tawg lub zog ntawm cov khoom txo mus rau 50% ntawm lawv cov nqi pib tom qab 20000 teev ntawm kev siv. Cov ntaub ntawv kuaj pom tseeb qhia tau tias cov ntaub ntawv polyester tuaj yeem ua tiav lub neej kev pabcuam ntawm 60000 teev ntawm 105℃C, thiab ua raws li Arrhenius txoj cai, lub neej kev pabcuam yuav muab ob npaug lossis ib nrab rau txhua 10℃C kub hloov.

CTI feem ntau cuam tshuam txog kev tiv thaiv kev tawm tsam thiab kev taug qab muaj peev xwm ntawm cov khoom siv rwb thaiv tsev nyob hauv qhov chaw muaj kuab paug, ncaj qha rau kev txiav txim siab tsim qhov deb ntawm Laminated busbar connectors nyob rau hauv siab -voltage applications, thiab yog ib qho tseem ceeb xaiv lub hauv paus rau voltage scenarios saum 1000V. Tus nqi elongation qhia txog cov khoom siv tensile tsis kam, nrog PET elongation tus nqi Ntau dua lossis sib npaug li 100%, ntau dua PI's 70%. Cov yam ntxwv no ua rau nws hloov tau ntau dua hauv cov txheej txheem xws li sealing thiab sealing pwm.

Ntxiv rau cov khoom siv hluav taws xob hloov tau yooj yim thiab nruj, cov hmoov txheej kuj yog ib qho tseem ceeb ntxiv rau Laminated tsheb npav bar rau kev lag luam rwb thaiv tsev, tshwj xeeb tshaj yog tsim rau kev kho rwb thaiv tsev ntawm ib tus neeg xyuas pib nrog cov duab nyuaj. Cov txheej txheem ntawm cov hmoov txau tuaj yeem ua tiav kev sib khi thiab kev tiv thaiv tag nrho ntawm tus neeg xyuas pib, daws qhov teeb meem ntawm epoxy resin txheej yog qhov nyuaj rau kev sib khi txoj hlua khi.

Nws yuav tsum tau muab sau tseg tias hmoov txheej txheej txheem feem ntau haum rau ib tug conductors uas tsis tuaj mus rau hauv ncaj qha kev sib cuag nrog lwm yam conductors, yog li cov rwb thaiv tsev tiv thaiv yuav tsum tau rau txoj hauj lwm tseem ceeb xws li cov ces kaum ntse ntawm tus neeg xyuas pib yog tsawg. Cov yam ntxwv no ua rau nws xaiv kev lag luam rau cov xwm txheej tshwj xeeb, ua kom muaj txiaj ntsig ntawm kev xaiv ntawm Busbar rau cov khoom siv hluav taws xob rwb thaiv tsev thiab ua tau raws li cov txheej txheem rwb thaiv tsev ntawm cov qauv sib txawv thiab kev ua haujlwm.

Yog tias koj muaj lus nug txog kev xaiv lossis parameter txuam ntawmLaminated tooj liab busbarcov ntaub ntawv rwb thaiv tsev, thov koj xav tiv tauj peb txhua lub sijhawm. Peb yuav muab koj cov lus qhia txog kev rwb thaiv tsev kom raug raws li cov xwm txheej ntawm qhov project, pab koj cov khoom ua tiav cov khoom siv hluav taws xob zoo thiab kev ntseeg siab.
