Evolution ntawm Tooj Liab Busbar Technology: Lub zog kis Innover Innation Usation Drived los ntawm cov khoom siv innovation thiab kev kho deg

Hauv cov tshuab hluav taws xob niaj hnub, tooj liab busbars yog cov qauv tseem ceeb ntawm kev faib khoom siv hluav taws xob, thiab lawv cov kev ua tau zoo cuam tshuam rau cov cuab yeej kev ntseeg tau thiab lub zog txuag hluav taws xob thiab lub zog ua haujlwm. Kab lus no tsom rau plaub pawg: neeg tooj liab busbars, tinned tooj liab busbars, thiab cov txheej txheem ntawm cov xwm txheej kev lag luam, thiab kev nthuav qhia cov kev lag luam thev naus laus zis.

 

 

 

Cov neeg Busbars tooj liab yog raws T2 tooj liab (huv siab dua lossis sib npaug ntawm 99.95%), tuav rawv lub ntuj ntawm cov hlau. Nws tiv taus yog li 0. 017ω ·. 017ω · mm² / m, thiab nws cov kev nqa khoom tam sim no zoo tshaj plaws. Nws yog qhov haum rau qhuav thiab huv si hauv tsev ib puag ncig, xws li hloov cov khoom thiab hloov pauv hluav taws xob sab hauv. Txawm hais tias tus tooj liab tau yooj yim oxidized rau saum huab cua, Torque kev tswj hwm ntawm cov khoom siv tsis sib xws, thiab kev tiv thaiv tsis zoo yog ruaj khov ntawm<100μΩ. Studies have shown that the initial oxide layer (thickness <1μm) can improve the heat dissipation efficiency by 14%, and the radiation heat dissipation accounts for 15%, which has unique advantages in temperature rise control. Typical applications include distribution cabinet busbars and industrial equipment grounding systems, and the cost is 15%-20% lower than that of surface-treated products.

 

 

Riveted txiv ntset tooj liab busbar sib xyaw ua ke ntawm qhov kawg ntawm lub busbar los ntawm kev ua kom txias dua tshiab kom ua tiav "so kom ceev ceev ceev". Nws cov ntsiab lus zoo:

1. Qauv Qauv Sib Tham (M 4- m12 cov lus qhia), sib dhos ua kom muaj txiaj ntsig nce los ntawm 40%;

2. Thread shear strength >80MPA, kev txo qis kev pheej hmoo txo ​​los ntawm 70% hauv ib puag ncig kev co;

3. Haum rau ntau yam kev teeb tsa kev teeb tsa thiab kev txhawb nqa ntsug / rov kho dua. Cov txheej txheem siv cnc punching + cov riveting hydraulic, nrog lub qhov tseeb raug ntawm ± {2}}. 1 hli thiab sib npaug ntawm 3.2μm.

Nws yog tsuas yog siv nyob rau hauv cov chaw tsim hluav taws xob tshiab thiab cov ntaub ntawv chaw PDU (cov kev xa hluav taws xob

 

 

Tin-plated copper busbars use an electrochemical tinning process (tin layer thickness 5-15μm), and the salt spray test is >1000 teev. Nws yog tsim nyog rau noo thiab ntsev txau kom ib puag ncig (xws li cov khoom siv hiav txwv ntug thiab hluav taws xob lub tsheb roj teeb hluav taws xob). Kev sib txawv ntawm cov txheej tin (CV tus nqi<5%) ensures welding consistency, the tinning time is shortened by 30%, and the contact resistance is <50μΩ. Technological breakthroughs include chromium-free passivation treatment (compliant with RoHS 3.0) to avoid electrochemical corrosion.

Cov ntawv thov raug: Cov hluav taws xob roj teeb sib txuas ({0}} Txoj cai nqa khoom siv tau), kev pab cuam tam sim no muaj ntau dua 15 xyoos.

 

 

Nickel-Plated tooj liab Busbar tau ua tiav kev txhim kho mus los ntawm electroplating npib tsib xee (tuab {1} μm):

1. Hardness HV ntau dua lossis sib luag rau 180, hnav tsis kam yog 3 zaug uas ntawm tus tooj liab liab, xws li cov tub mus txuas txuas txuas);

2. Kev kub-kub-oxidation tsis kam (ruaj khov hauv qab 300 degree), sib ntsib qhov nce ntawm cov khoom siv kub siab;

3. Electromagnetic shielding effectiveness> 60dB, adapted to the anti-interference requirements of precision electronic equipment. The bonding strength between the nickel layer and the copper substrate is> 5N/cm, and the salt spray test is>1500 teev.

 

Cov ntawv thov tseem ceeb: Kev Hloov Chaw Tawm Trit, Aerospace Fais Fab Cov Khoom Siv Hluav Taws Xob, thiab cov khoom lag luam nrog nruj me nyuam yuav tsum tau hnav tsis kam thiab corrosion tsis kam.
