Lub luag haujlwm tseem ceeb ntawm EV Fuse Contact Cap

May 14, 2025

Raws li lub tsheb hluav taws xob (EVs) txuas ntxiv mus, yog li cov thev naus laus zis uas txhawb nqa lawv cov kev ua tau zoo, kev nyab xeeb, thiab kev ntseeg tau. Ib qho feem ntau saib tsis taus tab sis tseem ceeb hauv EV lub siab -voltage system yog EV fuse hu rau lub hau, kuj hu ua fuse kawg cap lossis fuse riam hau. Cov khoom me me no ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab ua haujlwm zoo ntawm lub tsheb tiv thaiv hluav taws xob.

 

EV Fuse Contact Cap

 

 

 

EV Fuse Contact Cap yog dab tsi?

 

Lub EV Fuse Contact Riam Cap yog cov khoom siv hlau hlau feem ntau pom ntawm ob qho kawg ntawm lub siab -voltage fuse siv hauv tsheb fais fab. Nws lub luag haujlwm tseem ceeb yog muab kev ruaj ntseg hluav taws xob sib txuas ntawm lub fuse thiab cov khoom siv hluav taws xob sib txuas. Nws kuj tseem pab txhawb kom muaj txiaj ntsig zoo ntawm cov cua sov thiab cov tshuab ua kom muaj kev ruaj ntseg raws li qhov xav tau.

 

Ntsiab Function

Kev Siv Hluav Taws Xob

 

Lub hau kev tiv tauj ua kom muaj kev tiv thaiv tsawg kawg ntawm qhov chaw sib txuas, tso cai rau cov tam sim no ntws zoo los ntawm lub fuse. Kev ua tau zoo yog qhov tseem ceeb los tiv thaiv cov cua sov hauv zos lossis qhov hluav taws xob poob.

Mechanical Stability

 

Tsim los tiv thaiv kev vibrations thiab thermal expansion thaum lub tsheb ua haujlwm, lub hau npog lub fuse lub cev kom tsis txhob muaj kev cuam tshuam los yog kev sib raug zoo.

Thaum tshav kub kub Dissipation

 

Hauv siab - daim ntawv thov tam sim no, tswj qhov kub thiab txias yog qhov tseem ceeb. Lub hau tiv tauj pab kom cov cua sov tawm hauv lub fuse, txo qhov kev pheej hmoo ntawm thermal puas lossis kev laus ntxov ntxov.

Kev txiav txim siab ntawm cov khoom siv

 

EV fuse tiv tauj lub kaus mom feem ntau yog tsim los ntawm cov khoom siv siab tshaj -cov hlau xws li:

 

Tooj liab los yog tooj liab Alloys

 

Feem ntau siv vim nws zoo heev hluav taws xob conductivity. Tej zaum yuav yog nyiaj - lossis tin -plated los txhim kho corrosion.

 

Nickel{0}}Plated Materials

 

Muab kev txhim kho durability thiab oxidation tsis kam, tshwj xeeb tshaj yog nyob rau hauv siab - kub.

 

Kev xaiv cov khoom yog coj los ntawm cov hauv qab no

 

1. Hluav taws xob conductivity

Cov hluav taws xob hluav taws xob siab yog qhov tseem ceeb los txo qhov kev poob qis thiab tiv thaiv cov cua sov hauv zos thaum lub sijhawm ua haujlwm. Cov ntaub ntawv uas tsis tshua muaj zog, xws li tooj liab (Cu) thiab tooj liab alloys, feem ntau nyiam. Cov ntaub ntawv no ua kom muaj txiaj ntsig zoo tam sim no los ntawm EV fuse tiv thaiv lub kaus mom, txo lub zog poob thiab txhim kho tag nrho cov txiaj ntsig ntawm qhov siab -voltage system.

 

2. Thermal conductivity

Kev ua kom muaj cua sov ua kom zoo yog qhov tseem ceeb nyob rau hauv siab - tam sim no circuits, qhov twg fuses yuav muaj qhov kub thiab txias thaum lub sij hawm ib txwm muaj lossis ua txhaum. Cov ntaub ntawv uas muaj cov thermal conductivity siab pab faib cov cua sov kom deb ntawm lub fuse, txo cov thermal kev nyuaj siab thiab ncua kev pab cuam lub neej.

 

3. Corrosion thiab Oxidation Resistance

EV ib puag ncig feem ntau nthuav tawm cov khoom siv rau cov av noo siab, qhov kub thiab txias hloov pauv, thiab muaj peev xwm corrosive gases. Cov khoom siv xaiv yuav tsum tiv thaiv oxidation thiab nto corrosion kom muaj hluav taws xob ruaj khov nyob rau lub sijhawm.

 

4. Mechanical Strength thiab Formability

Lub hau kev sib cuag yuav tsum tiv taus kev ntxhov siab los ntawm cov txheej txheem sib dhos (xws li, crimping, vuam), kev vibration thaum lub tsheb ua haujlwm, thiab thermal expansion. Yog li ntawd, cov khoom siv hauv paus yuav tsum muaj.

 

Production process of resistance welding for fuse contact cap

 

 

Tsim nta

 

1. Nto Plating:

Txhawm rau txhim kho corrosion kuj thiab tiv tauj kev ntseeg tau.

 

2. Crimping lossis Vuam Zones:

Tsim los rau kev sib koom ua ke nrog lub cev fuse thiab cov khoom siv los ntawm crimping, laser vuam, lossis tsis kam vuam.

 

3. Dimensional Precision:

Tolerances yuav tsum nruj kom ntseeg tau tias kev sib raug zoo nrog cov neeg tuav fuse thiab cov khoom sib txuas, tshwj xeeb tshaj yog nyob rau hauv cov kab sib dhos.

 

Production Technology and Application of Fuse Contact Cap

 

 

Application Scenario hauv EVs

 

EV Fuse Cap thiab Contacts yog siv nyob rau hauv siab -voltage fuses uas tiv thaiv cov khoom tseem ceeb xws li:

Cov roj teeb pob

 

Lub pob roj teeb yog lub plawv ntawm EV, khaws cia thiab muab cov khoom siv hluav taws xob xav tau rau kev txhawb nqa thiab lwm yam haujlwm. High-voltage fuses tiv thaiv lub roj teeb pob los ntawm cov xwm txheej overcurrent uas tuaj yeem ua rau lub hlwb puas lossis ua rau thermal khiav.

 

Ib qho fuse siv nyob rau hauv pob roj teeb yuav muaj qhov ntsuas hluav taws xob ntawm 500V DC thiab qhov ntsuas tam sim no ntawm 100A. Nws ua kom ntseeg tau tias nyob rau hauv cov xwm txheej luv luv los yog overcurrent, lub fuse yuav tshuab, disconnecting lub roj teeb pob ntawm lub Circuit Court thiab tiv thaiv tej yam kev puas tsuaj xws li overheating los yog hluav taws.

 

Ntawm -Board Chargers (OBC)

 

OBC tso cai rau EV raug them siv AC lub zog los ntawm kev them nyiaj sab nraud. Nws hloov AC rau DC thiab muab nws rau lub roj teeb. Fuses nrog lub kaus mom tiv tauj hauv lub subsystem no muab kev tiv thaiv los ntawm kev tawm tswv yim surges thaum them nyiaj, Internal faults nyob rau hauv lub hwj chim hloov hluav taws xob Circuit Court.

 

Muab qhov chaw kaw cia thiab thermal txwv nyob rau hauv OBCs, lub hau kev tiv tauj yuav tsum muaj qhov loj me me, kev ua siab ntev haum, thiab muaj kev ntseeg siab nyob rau hauv kev rov ua dua thermal.

 

DC -DC converters

 

Lub zog tsav hluav taws xob, suav nrog lub inverter thiab lub tshuab hluav taws xob, hloov hluav taws xob hluav taws xob rau hauv lub zog siv tshuab los tsav lub tsheb. Fuses tiv thaiv cov khoom no los ntawm overcurrent thiab luv luv -circuit faults, tiv thaiv kev puas tsuaj rau lub cev muaj zog thiab inverter.

 

Lub fuse siv nyob rau hauv lub zog tsav hluav taws xob yuav muaj qhov ntsuas tam sim no ntawm 150A thiab qhov ntsuas hluav taws xob ntawm 600V DC. Nws xyuas kom meej tias lub inverter thiab lub cev muaj zog ua haujlwm zoo, txawm tias thaum lub sijhawm siab - lub zog xav tau xws li kev nrawm lossis nce toj.

 

DC -DC converters

 

Hauv txhua daim ntawv thov no, fuses ua raws li cov cuab yeej kev nyab xeeb. Thaum tam sim no tshaj qhov ntsuas tus nqi, lub fuse caij melts, rhuav lub Circuit Court thiab tiv thaiv kev puas tsuaj rau cov khoom kim thiab tseem ceeb.

 

Luv -Circuit Protection:

fuses muab kev tiv thaiv tam sim ntawd thaum muaj hluav taws xob luv luv. Los ntawm kev cuam tshuam cov dej ntws tam sim no, lawv tiv thaiv cov cua sov ntau dhau, hluav taws kub, thiab kev puas tsuaj rau lub tsheb hluav taws xob.

 

Ua raws li Cov Qauv Kev Nyab Xeeb:

Kev siv cov fuses ua kom lub tsheb ua tau raws li cov qauv kev nyab xeeb thiab cov kev cai, muab kev tsav tsheb txhim khu kev qha thiab nyab xeeb rau cov neeg siv.

 

Hauv cov kab hluav taws xob no, kev ua tsis tiav ntawm kev sib cais ua txhaum sai sai thiab ntseeg tau tuaj yeem ua rau cov khoom puas tsuaj, hluav taws kub hnyiab, lossis kev nyab xeeb tsis ua haujlwm. Yog li ntawd, kev ua haujlwm ntawm lub hau tiv tauj ncaj qha cuam tshuam rau kev nyab xeeb ntawm lub tsheb.

 

yav tom ntej tiam

 

Nrog rau kev thawb mus rau cov khoom siv hluav taws xob ntau dua (800V systems thiab tshaj), qhov kev thov rau cov khoom siv fuse uas tuaj yeem tiv taus qhov kub siab dua, cov dej ntws, thiab kev hloov pauv kev ntxhov siab yog nce. Kev nce qib hauv kev tsim lub hau tsom rau: Txhim kho arc tswj, kev ua haujlwm zoo dua thermal, thiab cov qauv me me los txhawb kev sib koom ua ke.

 

Txawm tias me me, lubFuse Cap thiab Contactsyog ib feem tseem ceeb ntawm kev ruaj ntseg hluav taws xob hauv tsheb tshiab. Los ntawm kev ua kom ntseeg tau kev sib txuas hluav taws xob, kev ua haujlwm zoo, thiab kev tswj xyuas thermal nws ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv lub siab -voltage systems uas tsav EVs niaj hnub.
