Puas yog Tin-Plated Bus Bar haum rau qhov chaw ntub dej

Raws li Tuam Tshoj Hluav Taws Xob Hluav Taws Xob (CEC), 32% ntawm ntug dej hiav txwv tshiab lub zog ua haujlwm tsis ua haujlwm hauv H1 2025 los ntawm tooj liab busbar corrosion vim muaj av noo siab. Lub tin -plated tsheb npav bar yog dav siv los tiv thaiv ya raws, tab sis ntau tus engineers tsis ntseeg nws qhov kev ua tau zoo. Kab lus no tham txog nws cov dej noo-cov ntsiab lus pov thawj, cov qauv kev sim, kev txhim kho cov qauv, daim ntawv thov scenarios thiab Xiamen APOLLO cov kev daws teeb meem.

 

 

1. Tin Layer Isolates Moisture

Lub tinned tooj liab busbar muaj 5-15μm tuab tin txheej. Nws npog tag nrho cov tooj liab. Nws thaiv kev ya raws, ntug dej hiav txwv ntsev thiab tooj liab los ntawm kev kov ncaj qha. Qhov no tiv thaiv oxidation thiab corrosion.

 

2. Passivation Zaj duab xis txhawb kev ruaj ntseg

Cov txheej tin tsim cov oxide tuab tuab (SnO₂) hauv huab cua ntub. Zaj duab xis no tsis yaj hauv dej. Nws tiv taus cov acids tsis muaj zog (xws li dej nag nrog CO₂). Nws khaws noo noo tsis kam rau lub sijhawm ntev.

 

3. Txo Galvanic Corrosion Risk

Tin muaj peev xwm zoo dua tooj liab. Thaum lub tin coated tooj liab busbar kov lwm cov hlau (xws li txhuas brackets) nyob rau hauv qhov chaw ntub dej, nws ua raws li cathode. Qhov no txo ​​galvanic corrosion ntawm tooj liab puag.

 

 

1. Kev kuaj ntsev tsuag:Lub tin plated tooj liab busbar yuav tsum dhau 48-teev nruab nrab ntsev tsuag (5% NaCl tov) yam tsis muaj xeb liab. Qhov no simulates ntug dej hiav txwv high-ntsev av. Nws ua kom tsis muaj corrosion rau ntau tshaj 5 xyoos ..

 

2. Damp heat cycle test:Muab lub busbar mus txog 50 lub voj voog ntawm "40 degree, 95% RH rau 12h → 25 degree, 60% RH rau 12h". Nws yuav tsum khaws conductivity Ntau dua los yog sib npaug rau 95% ntawm tus nqi pib. Lub tin txheej yuav tsum tsis txhob tev tawm.

 

3. Condensation resistance test:Muab lub busbar nyob rau hauv ib tug 5℃→ 40℃kub voj voog (1h / voj voog) kom condensation. Tom qab 200 cycles, cov rwb thaiv tsev tiv thaiv ntawm busbars yuav tsum nyob ntev dua los yog sib npaug rau 10¹⁰ Ω.

 

 

1. Sealed Connection Design

Siv silicone gaskets (tiv taus 150 degree, 95% RH) ntawm cov ntsiab lus txuas ntawm HDHC tinned tooj liab busbar. Lawv sau qhov khoob ntawm busbars thiab brackets, tiv thaiv ya raws los ntawm kev nkag mus rau hauv qhov chaw sib cuag

 

2. Qhov dej ntws Groove Layout

Ntxiv 1-2 hli sib sib zog nqus grooves rau ntawm qhov chaw ntawm tinned tooj liab busbar. Nyob rau hauv ib puag ncig high-humidity, condensed dej ntws tawm los ntawm cov grooves, tsis txhob muaj dej tsub zuj zuj uas ua rau lub zos corrosion.

 

3. Ntug Chamfering Kev Kho Mob

Chamfer cov npoo ntawm tin coated tooj liab busbar rau 0.5-1mm. Cov npoo ntse yooj yim khaws noo noo thiab ua kom muaj zog corrosion; chamfering txo cov dej noo thiab ua kom ntev kev pab cuam lub neej.

 

 

Tin-plated tsheb npav bar yog qhov tsim nyog rau qhov chaw ntub dej. Nyob rau hauv ntug dej hiav txwv 100MW + lub zog cia chaw nres tsheb, HDHC tinned tooj liab busbar resists ntsev tsuag corrosion. Nws ua kom ruaj khov xa hluav taws xob. Nyob rau yav qab teb Tuam Tshoj 480kW EV them chaw nres tsheb (ib xyoo nruab nrab RH Ntau dua lossis sib npaug li 80%), tin plated tooj liab busbar zam kev tiv thaiv kev tiv thaiv los ntawm oxidation. Hauv marine hluav taws xob systems (high humidity + ntsev pos), atinned tooj liab busbarua haujlwm ruaj khov rau ntau tshaj 8 xyoo. Nws ua haujlwm 3 zaug zoo dua li tsis muaj tooj liab. Cov xwm txheej no ua pov thawj tias nws tsim nyog.

 

 

Xiamen APOLLO's tin -plated tsheb npav bar siv siab -purity electrolytic tin (purity Ntau dua lossis sib npaug li 99.99%) rau txheej txheej plating. Lub thickness yog sib xws (8-12μm, kam rau ua ± 1μm). Nws yog qhov zoo dua li kev lag luam tsis sib xws 5-15μm plating. Peb HDHC tinned tooj liab busbar siv lub siab-density tooj liab substrate (density Ntau dua los yog sib npaug rau 8.9g / cm³). Qhov no txo ​​cov porosity thiab txhim kho cov dej tsis kam. Nws dhau 72-teev tshuaj tsuag ntsev. Nws ntsibIS09001-2015, IATF16949 thiab ROHScov qauv.

 

Peb muab kev pabcuam kev cai hloov tau. Rau cov ntug dej hiav txwv, sab qab teb lossis marine scenarios, peb kho cov tin txheej thickness (5-20μm) thiab tooj liab substrate loj (thickness 2-50mm, dav 10{10}}200mm) ntawm tin coated tooj liab busbar. Peb muaj thoob ntiaj teb hiav txwv, av thiab huab cua logistics los xyuas kom meej lub sijhawm xa khoom. Peb pab neeg tom qab-muag muab kev pab txhawb nqa 24-teev. Nws suav nrog rau ntawm qhov chaw noo noo-ntawv pov thawj kev taw qhia los daws cov neeg siv khoom 'humid ib puag ncig daim ntawv thov teeb meem.
