Lub luag haujlwm ntawm Copper Cap Fittings hauv EV Fuse Protection

Copper cap fittings yog cov khoom tseem ceeb hauv EV (hluav taws xob tsheb) fuses. Nws ua kom ruaj khov tam sim no kis tau tus mob. Nws tseem tiv thaiv fuse tsis ua haujlwm thaum lub sijhawm overloads. Tsis ntev los no, GB/T 38031-2025 "Cov Lus Qhia Txog Kev Nyab Xeeb rau Cov Roj Teeb Hluav Taws Xob rau Tsheb Hluav Taws Xob" tau muab tso rau siv. Kev thov rau cov khoom siv tooj liab zoo tau nce ntxiv. Kab lus no yuav tshawb txog nws lub luag haujlwm hauv EV fuse tiv thaiv los ntawm tsib yam: cov haujlwm tseem ceeb, kev lag luam tiam sis, daim ntawv thov teb, cov qauv zoo, thiab Xiamen APOLLO cov kev daws teeb meem.

 

 

1. Kev ua haujlwm ruaj khov tam sim no

Copper sab nrauv cap muaj hluav taws xob zoo heev. GB / T 13539.2 kev ntsuam xyuas qhia tias nws tsis kam yog tsawg dua lossis sib npaug rau 2mΩ ntawm 100A tam sim no. Qhov no ua rau tam sim no ntws zoo hauv EV fuses. Nws tseem tiv thaiv cov cua sov los ntawm kev ua tsis zoo

 

2. Kev Tiv Thaiv Kev Tiv Thaiv Arc

Sab nraum lub hau kawg tsim ib lub foob kaw ntom nti nrog lub fuse raj. Thaum lub fuse tshuab, nws thaiv arc to zoo. Qhov no nres arcs los ntawm kev puas tsuaj cov roj teeb nyob ze. Nws kuj tseem txo cov kev pheej hmoo hluav taws kub hauv EVs.

 

3. Kev Txhim Kho Cov Txheej Txheem

Copper kawg phaj boosts lub fuse lub mechanical zog. Nws tiv thaiv kev vibration thaum tsav tsheb EV (txog 15g acceleration). Qhov no ua rau lub fuse tsis zoo. Nws tseem ua kom lub sijhawm ntev - txhim khu kev qha ua haujlwm hauv cov tsheb hnyav.

 

 

1. Nyob rau lub Peb Hlis 2025, Ningbo Jintai Electronics launched ib tug tshiab tooj liab slip cap haum. Nws muaj qhov ceev - nruab qauv. Qhov no txiav EV fuse lub sijhawm sib dhos los ntawm 30%. Nws kuj tseem txhim kho kev ua haujlwm ntau lawm rau automakers ..

 

2. Daim ntawv tshaj tawm xyoo 2024 los ntawm Tuam Tshoj Cov Khoom Siv Hluav Taws Xob Kev Lag Luam tau tawm los. Nws hais tias tooj liab sab nrauv siv hauv EV fuses tau nce los ntawm 45%. Qhov no yog vim qhov kev thov hauv tsev rau siab -kev nyab xeeb EVs tau loj hlob

 

3. Tus tshiab GB/T 38031-2025 tus qauv muaj qhov yuav tsum tau ua. Nws hais tias tooj liab cap haum yuav tsum tiv taus 1000V voltage. Qhov no pushes manufacturers siv high-purity tooj liab (Ntau dua los yog sib npaug rau 99.95%) es tsis txhob siv cov tooj liab zoo tib yam.

 

 

Copper cap qhov chaw yog dav siv nyob rau hauv qhov tseem ceeb EV fuse scenarios. Hauv EV roj teeb pob fuses, tooj liab slip cap haum haum rau kev them nqi ntau zaus - tawm mus. Nws kuj tiv thaiv electrochemical corrosion. Hauv kev tswj lub cev muaj zog fuses, tooj liab sab nraud ua haujlwm siab tam sim no (txog 300A). Nws tswj kev ua haujlwm ruaj khov. Nyob rau hauv - board charger fuses, lub hau kawg sab nraud tiv taus qhov kub thiab txias (txog 120℃). Nws tsis deform. Cov ntawv thov no ua pov thawj lawv lub luag haujlwm tseem ceeb hauv EV kev nyab xeeb.

 

 

1. Cov khoom siv Purity Test

GB / T 5231 muaj ib txoj cai rau tooj liab kawg phaj: nws cov tooj liab purity yuav tsum siab tshaj los yog sib npaug rau 99.95%. Atomic absorption spectrometry yog siv los xyuas cov impurities. Qhov no ua kom lub fitting muaj zoo conductivity thiab corrosion kuj.

 

2. Siab -Tsuas Kub Ua Haujlwm

Outer kawg capyuav tsum dhau 120℃tas li - ntsuas kub. Qhov kev xeem no kav 1000 teev. Tom qab qhov kev xeem, nws qhov kev hloov pauv yuav tsum tsawg dua lossis sib npaug li 0.1%. Qhov no ua kom nws ua haujlwm ib txwm nyob hauv siab -kub EV ib puag ncig

 

3. Vibration Resistance Test

Copper slip cap haum yuav tsum tau ua 15g acceleration vibration tests. Cov kev ntsuam xyuas npog X, Y, Z axes (2 teev txhua). Nws yuav tsum tsis txhob xoob lossis tawg tom qab kev sim. Qhov no ua tau raws li qhov xav tau ntawm kev vibration ntawm EV tsav.

 

4. Daim Ntawv Pov Thawj Ua Raws Cai

Txhua lub hau tooj liab yuav tsum tau txais daim ntawv pov thawj CQC. Rau kev xa tawm mus rau Tebchaws Europe, lawv kuj yuav tsum tau ua raws li IEC 60127 tus qauv. Qhov no ob daim ntawv pov thawj lav lawv txoj kev nyab xeeb hauv ntiaj teb EV kev lag luam.

 

 

Xiamen APOLLO ua tau siab -kev ua tau zoo tooj liab cap qhov chaw rau EV fuses. Cov no muaj xws li tooj liab sab nrauv cap, sab nraud cap, tooj liab slip cap haum, thiab tooj liab kawg phaj. Peb cov khoom siv 99.97% siab -purity tooj liab. Dimensional kam rau ua yog tswj nyob rau hauv ± 0.01mm. Qhov no ua kom muaj kev sib raug zoo nrog ntau yam EV fuse qauv ..

 

Peb tuav ISO 9001: 2015 thiab IATF 16949 certifications (automotive kev lag luam tus qauv). Peb muab kev xa khoom yooj yim: hiav txwv shipping (20-25 hnub) rau kev txiav txim ntau, huab cua shipping (3-5 hnub) rau kev xav tau ceev, thiab kev xa khoom hauv av (2-3 hnub) rau cov tuam txhab EV hauv tsev. Peb pab neeg technical muab kev pabcuam kev cai. Peb tuaj yeem tsim kev cai tooj liab cap Cheebtsam raws li cov neeg siv khoom kos duab. Lub voj voog kev loj hlob tsuas yog 7-10 hnub. Xaiv Xiamen APOLLO txhais tau tias tau txais kev ruaj ntseg kev ruaj ntseg lav rau EV fuse tiv thaiv nrog zoo tooj liab cap fittings.
