Kev Ntsuam Xyuas Ntawm Hlau Drawing Thiab Nickel Plating Technology nyob rau hauv Cov Txheej Txheem Kho Nto Ntawm Cov Ncauj Ncauj Busbars

Hauv kev tsim khoom thiab tsim cov txheej txheem ntawm cov tooj liab busbars thoob plaws hauv lawv lub neej, cov txheej txheem kho saum npoo zoo li qhov txuas tseem ceeb uas muab cov khoom lag luam "lub neej thib ob". Ntawm lawv, cov txheej txheem kos duab nto hlau thiab cov tshuab nickel plating yog ob txoj kev kho mob tseem ceeb. Los ntawm lub microscopic mus rau qib macroscopic, lawv zoo li qhov ua tau zoo thiab kev pabcuam lub neej ntawm Hluav Taws Xob Hluav Taws Xob Bar hauv txhua yam. Lawv qhov tseem ceeb yog tus kheej - pom tseeb.

 

 

Cov txheej txheem saum npoo hlau yog qhov tseem ceeb ntawm qhov kev hloov kho tshuab raws li lub hauv paus ntsiab lus ntawm kev siv tshuab. Nws cov ntsiab lus nyob rau hauv kev tsim lub microstructure tsis tu ncua nyob rau saum npoo ntawm Ground Bus Bar los ntawm cov teebmeem tshwj xeeb ntawm lub cev. Tshwj xeeb tshaj yog, cov khoom siv kos duab hlau feem ntau siv hauv kev xyaum ntau lawm feem ntau yog muab faib rau hauv cov menyuam hlau kos duab tshuab thiab xuab zeb siv hlau kos tshuab. Lub tshuab siv lub tshuab nqus hlau siv cov carbide rollers nrog cov qauv sib txawv los tsim cov kev sib txheeb ze nrog cov tooj liab busbar nto nyob rau hauv lub tsav ntawm lub cev muaj zog, thiab "replicates" cov qauv ntawm cov menyuam nto mus rau tooj liab busbar nto los ntawm lub siab; txoj siv sia siv lub tshuab nqus tsev cia siab rau qhov siab -ceev khiav xuab zeb siv los txiav BusBar Hluav Taws Xob nto los ntawm kev sib tsoo ntawm cov xuab zeb hais.

 

Hauv kev ua haujlwm tiag tiag, tus neeg teb xov tooj yuav tsum tau kho kom raug ntau yam tsis zoo ntawm cov cuab yeej kos duab hlau raws li cov lus qhia, cov ntaub ntawv, thiab cov ntawv thov zaum kawg ntawm BusBar rau ABB. Piv txwv li, rau thinner tooj liab busbars, ib tug tsawg dua hlau daim duab ceev (kwv yees 5-10m / min) thiab ib tug me me siab (0.1-0.3MPa) yuav tsum tau tiv thaiv cov hluav taws xob tooj liab BusBar los ntawm deforming; rau thicker tooj liab busbars, qhov ceev thiab siab tuaj yeem tsim nyog nce, thiab cov nyhuv zoo tagnrho tuaj yeem maj mam ua tiav los ntawm ntau cov hlau kos duab.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Qhov zoo ntawm cov txheej txheem no nthuav tawm ntau- tus yam ntxwv ntawm qhov loj me:

1. Aesthetic tus nqi nce ntxiv:Tom qab xaim kos duab, cov qauv sib txuas lossis ntoo khaub lig tsim nyob rau saum npoo ntawm Copper Solid Bus Bar rhuav tshem cov iav monotonous ntawm cov khoom siv tooj liab qub, muab cov khoom lag luam tshwj xeeb zoo nkauj. Qhov kev ntxhib los mos no tsis tsuas yog txhim kho qhov pom tag nrho hauv cov khoom faib khoom, hloov cov txee, thiab lwm yam khoom siv tab sis kuj ua rau nws yooj yim dua rau cov neeg teeb tsa kom paub sai sai cov busbars nrog ntau lub zog.

2. Optimized conductivity:Kev tshem tawm ntawm cov yeeb yaj kiab oxide nto thiab cov impurities txhim kho cov atomic - theem flatness ntawm tooj liab busbar nto. Cov kev tshawb fawb tau pom tias qhov roughness ntawm Ra tus nqi ntawm lub hwj chim BusBar tom qab zoo hlau kos duab yuav raug txo los ntawm tus thawj 3-5μm mus rau 0.5-1μm, uas ua rau kev sib cuag nrog cov hluav taws xob connector los ze zog thiab txo qhov kev tiv thaiv los ntawm 8% -12%. Nyob rau hauv high-power kis scenarios, nws muaj peev xwm txo tau lub zog poob thiab cua sov tsim.

3. Txhim khu kev tiv thaiv nto:Lub microscopic kev ntxhib los mos tsim los ntawm cov hlau kos duab nce qhov chaw ntawm qhov chaw mus rau ib qho twg. Thaum muaj kev tiv thaiv tom ntej xws li npib tsib xee plating, thaj chaw sib cuag loj tuaj yeem muab cov chaw sib txuas ntau dua, uas ua rau muaj qhov adhesion ntawm plating thiab Bus Bar Electric los ntawm 30% -50%, tiv thaiv cov plating los ntawm tev tawm thaum siv mus ntev.

 

Nickel plating thev naus laus zis yog ib qho tseem ceeb txhais tau tias tsim kom muaj cov txheej txheem hlau ua haujlwm nyob rau saum npoo ntawm tooj liab busbar. Nws txoj cai yog ua raws li cov tshuaj tiv thaiv electrochemical lossis tshuaj txo cov tshuaj tiv thaiv ntawm cov hlau ions. Raws li cov txheej txheem sib txawv, nws tau muab faib ua ob txoj hauv kev: electroplating nickel thiab tshuaj nickel plating. Electroplating npib tsib xee yog ua kom cov nickel ions hauv cov txheej txheem plating tau txais cov khoom siv hluav taws xob nyob rau saum npoo ntawm High Voltage BusBar nyob rau hauv qhov kev txiav txim ntawm DC hluav taws xob teb, thiab tso nyiaj los tsim ib txheej hlau nickel; chemical nickel plating yog siv tus neeg sawv cev txo qis (xws li sodium hypophosphite) kom txo tau thiab tso nyiaj npib tsib xee ions rau ntawm qhov chaw ntawm tooj liab busbar nrog catalytic kev ua si yam tsis muaj lub zog sab nraud. Ob txheej txheem muaj lawv tus kheej yam ntxwv.

 

Electroplating npib tsib xee muaj qhov zoo ntawm kev ceev deposition ceev thiab muaj zog controllability ntawm txheej thickness, uas yog haum rau loj ntau lawm; chemical npib tsib xee plating tuaj yeem tsim cov txheej txheej txheej ntawm cov duab nyuaj, tshwj xeeb tshaj yog tsim rau kev kho mob ntawm qhov muag tsis pom, qhov tob tob, thiab lwm qhov chaw.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Lub luag haujlwm tseem ceeb ntawm nickel plating thev naus laus zis tau tshwm sim hauv ntau yam:
1. Corrosion kuj leaps:Nickel tuaj yeem tsim cov yeeb yaj kiab oxide ntom ntom (NiO) hauv huab cua. Cov oxide zaj duab xis no tsuas yog ob peb nanometers tuab, tab sis muaj tshuaj lom neeg ruaj khov thiab tuaj yeem thaiv cov pa oxygen, noo noo, thiab cov roj corrosive los ntawm kev hu rau lub tsheb npav tooj liab. Nyob rau hauv ib qho chaw ua lag luam, liab qab tooj liab busbars tsis muaj npib tsib xee plating tej zaum yuav pom tseeb xeb nyob rau hauv ob peb lub hlis, thaum busbars tom qab npib tsib xee plating muaj peev xwm tuav tsis muaj teeb meem ntawm corrosion ntawm qhov chaw rau 3-5 xyoo. Nyob rau hauv qhov chaw siab ntsev pos huab ib puag ncig xws li cov ntug hiav txwv dej, kev tiv thaiv ntawm cov nickel plating txheej yog qhov tseem ceeb, uas tuaj yeem txuas lub neej kev pab cuam ntawm busbar mus txog 8-10 xyoo.

2. Synergistic li ntawm hluav taws xob thiab thermal conductivity:Txawm hais tias cov hluav taws xob conductivity ntawm npib tsib xee qis dua li ntawm tooj liab, nws tseem nyob rau theem siab (li 27% ntawm tooj liab), thiab nws cov thermal conductivity zoo. Cov hlau nplaum tsim los ntawm cov npib tsib xee - txheej txheej thiab cov npib tsib xee-Plated Bus Bar kom ntseeg tau tias tam sim no thiab cua sov tuaj yeem sib kis tau zoo ntawm ob qhov sib txuas hlau. Nyob rau hauv siab - zaus circuits, cov nickel plating txheej tuaj yeem txo qhov cuam tshuam ntawm daim tawv nqaij thiab txhim kho kev ruaj ntseg ntawm cov teeb liab; nyob rau hauv cov khoom siv uas yuav tsum tau kub dissipation, qhov zoo thermal conductivity ntawm cov nickel plating txheej thiab lub dab dej kub yuav pab kom sai sai dissipate lub tshav kub generated los ntawm busbar thaum lub sij hawm ua hauj lwm.

3. Kev txhim kho tseem ceeb hauv kev ua haujlwm vuam:Cov txheej tooj liab oxide tsim los ntawm qhov yooj yim oxidation ntawm Nickel npib tsib xee-plated tooj liab busbar nto nyob rau hauv cov huab cua yuav cuam tshuam rau cov vuam zoo, thaum lub nickel plating txheej tuaj yeem cais cov pa oxygen thiab ua kom thaj chaw vuam huv si. Nyob rau tib lub sijhawm, npib tsib xee tau zoo wettability nrog solder (xws li tin- txhuas alloy, lead- dawb solder), uas tuaj yeem txo qhov kub thiab txias, txo lub sijhawm vuam, ua kom cov pob qij txha puv thiab firmer, thiab txo qhov tshwm sim ntawm vuam tsis xws li txias soldering thiab desoldering.

 

Hauv kev tsim khoom tiag tiag, cov txheej txheem kos duab nto hlau thiab cov tshuab nickel plating feem ntau tsim muaj kev sib raug zoo sib raug zoo. Ua ntej, lubtooj liab busbaryog pretreated los ntawm cov txheej txheem kos duab hlau kom tshem tawm cov impurities saum npoo thiab tsim cov qauv tsim microscopic ntxhib; Tom qab ntawd nickel plating yog ua kom cov nickel ions tuaj yeem sau rau hauv cov kab tsim los ntawm kev kos duab los ua "mosaic" plating qauv, uas tsis tsuas yog txhim kho cov adhesion ntawm plating tab sis kuj tseem txhim kho kev tiv thaiv tag nrho thiab kev ua haujlwm hluav taws xob. Nrog rau kev tshwm sim tas li ntawm cov ntaub ntawv tshiab thiab cov thev naus laus zis tshiab, cov txheej txheem kev kos duab nto hlau thiab cov tshuab nickel plating yuav tsim kom muaj kev txawj ntse, ntsuab, thiab ua kom zoo rau yav tom ntej, thiab txuas ntxiv muab lub zog muaj zog rau kev kho dua tshiab thiab cov khoom lag luam iteration ntawm cov tooj liab liab busbar kev lag luam.
