Yuav Ua Li Cas EV Fuse Ceramic Lub Cev Lub Cev daws sai sai - Them Overheating

Raws li Sina Auto, Tuam Tshoj muaj ntau tshaj 120,000 480kW+ ultra-pab pawg ceev ceev hauv H1 2025. 800V EVs ua tau li 38% ntawm kev muag tsheb tshiab. Kev them nyiaj ceev ua rau muaj kev pheej hmoo siab tshaj rau fuses. EV fuse ceramic lub cev yog qhov tseem ceeb los kho qhov teeb meem no. Kab lus no hais txog nws cov cua sov- daws cov kev cai, kev ua haujlwm ntawm cov khoom siv, kev tsim qauv, daim ntawv thov scenarios thiab Xiamen APOLLO cov kev daws teeb meem.

 

 

1. Ua kom muaj cua sov ua haujlwm zoo

Lub cev ceramic rau EV fuses muaj thermal conductivity ntawm 1.8-2.2 W / (m·K). Nws yog 3 npaug siab dua li cov yas yas. Nws sai sai txav cua sov los ntawm fuse txuas mus rau sab nraud. Qhov no txwv tsis pub cov cua sov hauv zos thaum lub sij hawm 480kW ceev them.

 

2. Arc quenching thiab cua sov nqus

Lub cev ceramic rau ev fuse tuaj yeem sawv ntsug 1200℃siab kub. Thaum them ceev ceev ua rau muaj kev kub ntxhov tam sim no, nws absorbs arc cua sov tam sim ntawd. Nws quenches arcs hauv 0.02 vib nas this. Qhov no txwv tsis pub cua sov los ntawm kev sib sau ua ke thiab ua rau cov khoom puas

 

3. Rwb thaiv tsev thiab cua sov cais

Lub cev ceramic muaj qhov ntim tiv taus tshaj 10¹⁴ Ω·cm. Nws cais qhov siab -kub fuse txuas los ntawm qhov chaw nyob ze. Qhov no txwv tsis pub cua sov los ntawm kev txav mus rau cov pob roj teeb lossis cov khoom siv them nyiaj thaum them nyiaj ceev.

 

 

1. Siab -kub stability:Ceramic raj rau high voltage fuse siv 95% purity steatite ceramic. Txawm tias ceev ceev - them tam sim no hits 1500A thiab qhov kub ntawm qhov chaw ncav cuag 600 degree, nws yuav tsis soften los yog deform.​

 

2. Tsawg thermal expansion:Lub cev ceramic lub thermal expansion coefficient tsawg dua lossis sib npaug li 5 × 10⁻⁶ / degree. Qhov no tsis txhob tawg los ntawm kev hloov kub ceev (los ntawm 25℃mus rau 500℃hauv 10 vib nas this) thaum them ceev.

 

3. Corrosion kuj:Ceramic nto muaj cov tshuaj tiv thaiv - oxidation txheej. Nws tiv thaiv kev puas tsuaj los ntawm roj teeb electrolytes thiab them chaw nres tsheb av noo. Qhov no ua rau nws cov cua kub dissipation ua tau zoo rau lub sijhawm ntev.

 

 

1. Ntau-Channel Heat Dissipation Grooves

Ntxiv 4-6 axial grooves rau ntawm phab ntsa sab nrauv ntawm ib qho ceramic casing rau fuse txuas. Cov grooves nce tshav kub dissipation cheeb tsam los ntawm 40%. Qhov no ua kom cov cua sov tso tawm thaum lub sijhawm 30-feeb them ceev (0-80% SOC).

 

2. Hollow Cavity Thaum tshav kub kub Buffer

Tsim ib 2 hli - tuab hollow kab noj hniav nyob rau hauv lub cev ceramic. Cov kab noj hniav ua raws li lub tshav kub buffer. Nws slows cia cua sov hloov mus rau lub casing nto los ntawm 25%. Qhov no tiv thaiv qhov kub thiab txias nyob ze -sensitive Cheebtsam.​

 

3. Sealed Thaum tshav kub kub-Resistant Gasket

Siv silicone gaskets ntawm lub cev lub cev cov chaw nres nkoj. Cov gaskets no tuaj yeem sawv ntsug 300℃siab kub. Lawv txwv cov plua plav thiab noo noo los ntawm thaiv cov cua kub dissipation raws. Lawv kuj dais qhov kub thiab txias los ntawm kev them nyiaj ceev.

 

 

IbEV fuse ceramic lub cevyog dav siv nyob rau hauv ceev -them-txog tshuab. Hauv 800V EV roj teeb pob, nws daws cov cua sov thaum lub sijhawm 10-feeb ultra- them ceev (5C tus nqi). Nyob rau hauv 480kW DC charging pawg, lub raj ceramic rau EV DC fuse tuav 1200A ncov tam sim no yam tsis muaj cua sov. Hauv kev lag luam EV them chaw nres tsheb (nrog 10+ pawg), nws khaws cov cua sov kom ruaj khov txawm tias lub sijhawm 8-teev nrawm nrawm nrawm. Cov xwm txheej no ua pov thawj tag nrho nws lub peev xwm los daws cov nqi hluav taws xob ceev ceev.

 

 

Xiamen APOLLO lub cev ceramic rau EV fuses siv 96% siab -purity steatite ceramic. Nws yog siab dua li 95% purity feem ntau siv hauv kev lag luam. Qhov no txhim kho cov thermal conductivity los ntawm 8%. Nws ua kom sov dissipation ruaj khov thaum lub sij hawm them ceev. Peb lub cev ceramic rau ev fuse mus txog 4- kauj ruam kev kuaj xyuas (qhov ntom ntom, thermal conductivity, kub-resistant, rwb thaiv tsev). Nws nruj dua li kev lag luam 3-kauj ruam xyuas. Nws ua tau raws li IATF 16949 thiab UL cov qauv ..

 

Peb muab kev pabcuam kev cai hloov tau. Peb kho qhov ntev (10-30mm) thiab puab txoj kab uas hla (5-15mm) ceramic raj rau high voltage fuse. Peb ua qhov no raws li cov neeg siv khoom nrawm- them cov qauv fuse. Nws haum 400V / 800V platforms. Peb lub ntiaj teb hiav txwv- av- huab cua logistics ua haujlwm zoo. Nws xa mus rau European ports nyob rau hauv 18-25 hnub, North American ports nyob rau hauv 15-22 hnub, thiab Southeast Asian lub teb chaws nyob rau hauv 5-10 hnub. Peb pab neeg tom qab-muag muab kev cob qhia hauv 24 teev. Nws pab cov neeg siv khoom daws cov teeb meem ceev ceev kom txo cov cua sov kom sib haum.
