Laminated Busbars Insulation Material Analysis: Yuav Ua Li Cas Yooj Yim thiab Rigid Rwb thaiv tsev cuam tshuam rau kev ua haujlwm?

Nrog rau kev loj hlob sai ntawm lub zog tshiab tsheb, lub zog cia tshuab, kev tsheb ciav hlau, thiab cov khoom siv hloov pauv zaus, laminated busbars tau dhau los ua qhov tseem ceeb ntawm cov khoom sib txuas hauv siab - lub zog hluav taws xob hluav taws xob. Txawm hais tias nws yog laminated busbar rau hluav taws xob tsheb, laminated busbar nyob rau hauv lub siab - lub hwj chim converter, los yog ib tug customized laminated busbar rau IGBTs, nws cov kev ua tau zoo tsis yog nyob ntawm tus neeg xyuas pib tsim xwb tab sis kuj nyob ze ntawm kev xaiv cov ntaub ntawv rwb thaiv tsev.

 

Cov txheej txheem rwb thaiv tsev ncaj qha cuam tshuam rau lub busbar tiv thaiv qhov hluav taws xob, kev ua haujlwm tawm ib nrab, kev pabcuam lub neej, thiab kev ntseeg tag nrho. Kev nkag siab txog cov yam ntxwv ntawm cov rwb thaiv tsev hloov tau yooj yim thiab nruj yog qhov tseem ceeb rau kev tsim cov qib siab -kev ua tau zoo laminated qis- inductive busbars.

 

 

 

Lub laminated busbar yog ib qho kev sib txuas ua ke uas muaj ntau cov txheej txheem ntawm cov neeg xyuas pib thiab cov ntaub ntawv insulating, uas yog ib feem ntawm Multi-Layer Composite Structure Connection Bar qauv.

 

Los ntawm nruj nreem stacking qhov zoo thiab tsis zoo conductors thiab cais lawv nrog ib tug insulating txheej, voj inductance yuav txo tau zoo, system electromagnetic compatibility kev ua tau zoo, thiab lub zog poob. Yog li ntawd, nws yog dav siv nyob rau hauv:

 

Electric tsheb tsav systems
Zog cia converters (PCS)
Muaj zaus converters
Photovoltaic inverter
Rail transit fais fab system
High -cov khoom siv fais fab fais fab

 

Hauv ntau- txheej txheej xws li peb- txheej laminated busbars, cov khoom siv insulating tsis tsuas yog muab hluav taws xob cais tab sis kuj muaj kev tiv thaiv ib puag ncig thiab kev tiv thaiv ib puag ncig.

 

 

 

Tam sim no, feem ntau ntawm cov laminated busbars siv tau yooj yim insulating films laminated mus rau tooj liab conductors.

 

Cov ntaub ntawv rwb thaiv tsev yooj yooj yim feem ntau yog sib txuas kom nruj rau tus neeg xyuas pib los ntawm cov txheej txheem kub - nias, ua kom tiav cov foob ntawm tus neeg xyuas pib, yog li txhim kho kev tiv thaiv rau ya raws thiab cua sov, muaj kuab paug, thiab kev laus.

 

PET Polyester rwb thaiv tsev khoom

PET yog ib qho ntawm feem ntau cov ntaub ntawv insulating rau ntau txheej busbars.

Nws cov yam ntxwv tseem ceeb muaj xws li:

Ntev -lub sijhawm ua haujlwm kub txog 105℃;
ductility zoo heev; Tsis tshua muaj kev tawg thaum khoov.
Zoo heev nto zoo;
Cov nplaim retardant zoo; Tus nqi pheej yig.

Vim nws qhov siab CTI (cov txheeb ze taug qab Performance index), PET yog tshwj xeeb tshaj yog haum rau high -voltage applications.

Cov ntaub ntawv PET tau siv dav hauv Subway Laminated Busbars thiab cov tshuab hluav taws xob muaj zog.

PI Polyimide rwb thaiv tsev khoom

PI yog qhov siab -kev ua tau zoo, siab- kub- cov khoom siv rwb thaiv tsev.

Nws cov txiaj ntsig tseem ceeb suav nrog:

Ntev -lub sij hawm kub tsis kam tshaj 200℃;
Zoo thermal stability;
Zoo weldability; High inherent nplaim retardancy.

Yog li, PI cov ntaub ntawv muaj qhov zoo tshaj plaws hauv IGBT Laminated Busbars thiab cov ntawv thov uas xav tau cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab lwm yam khoom siv.

Txawm li cas los xij, PI cov ntaub ntawv muaj qhov tsis muaj zog ntawm kev taug qab qhov chaw thiab yog kim dua PET. Lawv feem ntau yog siv rau hauv daim ntawv thov tshwj xeeb es tsis yog cov qauv tsim.

 

 

Saj zawg zog rwb thaiv tsev feem ntau npog cov neeg xyuas pib, thaum cov rwb thaiv tsev nruj feem ntau yog kev sib cais ntawm cov txheej txheem ntawm cov neeg xyuas pib.

 

Nyob rau hauv siab -voltage systems, nyias- zaj duab xis rwb thaiv tsev ib leeg yog feem ntau tsis txaus kom ua tau raws li ib feem ntawm qhov tso tawm thiab qhov kev ncua deb, yuav tsum tau ntxiv cov txheej txheem rwb thaiv tsev nruj.

 

Common rigid insulation cov ntaub ntawv muaj xws li:

Cov iav fiber reinforced polyester board

Epoxy fiberglass board

Siab - muaj zog insulating cov ntaub ntawv sib xyaw

Lub thickness ntawm nruj rwb thaiv tsev yog feem ntau txiav txim siab raws li qhov system khiav hauj lwm voltage.

 

Nyob rau hauv dav dav engineering tsim:

Kwv yees li ntawm 1 hli ntawm rwb thaiv tsev nyob deb yuav tsum tau rau txhua txhua 1kV nce nyob rau hauv kev khiav hauj lwm voltage.
Qhov siab dua qhov voltage, qhov ntau dua qhov nruj rwb thaiv tsev thickness.
High -voltage systems yuav xav tau cov txheej txheem rwb thaiv tsev 3-6mm los yog tuab dua.

 

Yog li ntawd, nyob rau hauv siab -voltage applications xws li High Voltage Explosion-Cov pov thawj Inverter Busbar, nruj rwb thaiv tsev tau dhau los ua ib qho tseem ceeb thiab tseem ceeb tivthaiv.

 

 

RTI-Relative Temperature Index

RTI (Relative Thermal Index) sawv cev rau qhov ntsuas kub siab tshaj plaws uas cov khoom siv insulating tuaj yeem ua haujlwm tsis tu ncua rau lub sijhawm ntev.

Qhov ntsuas no yog siv los ntsuas cov khoom muaj peev xwm los tswj cov khoom siv dag zog thiab cov khoom siv hluav taws xob nyob rau hauv ntev - lub sij hawm thermal aging.

Feem ntau:

 

Qhov kub siab dua ua rau cov khoom siv lub neej luv.

Rau txhua txhua 10℃nce nyob rau hauv qhov kub thiab txias, cov ntaub ntawv lifespan tej zaum yuav halved.

Rau txhua txhua 10℃txo qhov kub, cov khoom siv lifespan yuav ob npaug.

Yog li ntawd, rau ntev -lub sij hawm ua laminated busbars rau complex busbar installation, RTI (Relative Tracking Index) yog ib qho tseem ceeb ntawm cov khoom xaiv.

 

CTI-Cov txheeb ze Tracking Index

CTI ntsuas qhov tsis kam ntawm cov khoom siv insulating nto rau kev taug qab.

Cov txiaj ntsig CTI siab dua:

Cov kev xav tau me me ntawm qhov deb;
Muaj zog tiv thaiv kab mob;
Muaj kev nyab xeeb thiab ruaj khov ua haujlwm ntawm high voltages.

Rau cov ntawv thov saum toj no 1000V, CTI feem ntau yog qhov tseem ceeb ntawm kev txiav txim siab tsim rwb thaiv tsev.

 

Elongation

Elongation qhia txog cov khoom muaj peev xwm tiv thaiv tawg thiab thinning thaum ncab.

High elongation txhais tau tias:

Zoo dua haum rau cov txheej txheem khoov nyuaj;
Yooj yim dua tus neeg xyuas pib ntug sealing;
Kev ntseeg siab ntawm rwb thaiv tsev.

PET cov ntaub ntawv feem ntau muaj elongation tshaj 100%, thaum PI cov ntaub ntawv feem ntau muaj qis elongation dua tus tsiaj.

 

 

Industrial Power Systems

Cov ntawv thov kev lag luam feem ntau suav nrog:

Kev khiav hauj lwm voltages ntawm 1000V txog 6000V;
Ntev - lub sijhawm ua haujlwm yuav tsum tau ua;
High ib feem yuav tsum tau tso tawm;
nruj creepage nrug specifications.

Yog li ntawd, Laminated Busbars rau Peb -Level Inverters thiab cov tsheb loj converter tshuab feem ntau siv kev sib xyaw ua ke ntawm cov rwb thaiv tsev hloov tau yooj yim thiab nruj.

 

Kev Siv Lub Tsheb Hluav Taws Xob Tshiab

Tshiab zog tsheb tshuab feem ntau ua hauj lwm ntawm voltages concentrated nyob rau hauv:

400V platforms

800V platforms

Vim yog qhov qis dua voltage theem:

Tsawg ib feem ntawm qhov tso tawm;
Rigid rwb thaiv tsev tsis yog yuav tsum tau nyob rau hauv feem ntau scenarios.
Kev tsom xam yog rau kev tsim qauv hnyav thiab siv qhov chaw.

Yog li ntawd, Laminated Busbars rau Lub Tsheb Hluav Taws Xob feem ntau ntiav cov teeb yuag laminated kom tau raws li qhov xav tau ntawm lub zog loj.

 

 

 

Ntxiv nrog rau cov tsoos laminated rwb thaiv tsev, hmoov txheej thiab epoxy txheej kuj yog cov txheej txheem rwb thaiv tsev.

 

Cov txheej txheem no tsim nyog rau cov txheej txheem nyuaj lossis ib zaug -cov ntawv thov kev coj ua, ua tiav:

Kev tiv thaiv saum npoo av;
Kev tiv thaiv corrosion;
Ib puag ncig sealing.

Txawm li cas los xij, rau lub tsheb npav bar uas xav tau qis inductance thiab kev ntseeg siab, laminated rwb thaiv tsev tseem yog cov ntsiab lus tseem ceeb.

 

 

Nrog rau kev txhim kho txuas ntxiv ntawm lub zog hluav taws xob thev naus laus zis, laminated busbars tau hloov zuj zus los ntawm cov khoom siv hluav taws xob yooj yim mus rau hauv cov khoom tseem ceeb sib xyaw ua ke, hluav taws xob hluav taws xob, rwb thaiv tsev, thiab electromagnetic optimization. Txawm hais tias siv rau cov tsheb tshiab, tsheb ciav hlau, lossis cov khoom siv hluav taws xob hloov hluav taws xob, qhov kev xaiv tsim nyog ntawm cov ntaub ntawv rwb thaiv tsev cuam tshuam ncaj qha rau lub cev kev nyab xeeb, kev cia siab, thiab kev ua neej nyob.

 

Rau niaj hnublaminated busbarkev tsim qauv, rwb thaiv tsev hloov pauv yog lub luag haujlwm ua kom tau txais txiaj ntsig zoo ntawm tus neeg xyuas pib encapsulation, thaum lub rwb thaiv tsev nruj ua tau raws li qhov siab -voltage tiv taus cov cai. Ua ke, lawv ua kom lub sijhawm ntev - haujlwm ruaj khov ntawm tag nrho lub zog hluav taws xob.
