Brazing Silver Contacts rau tooj liab tuav
Khoom Description
Hauv qis- thiab nruab nrab-voltage hluav taws xob systems, Brazing Silver Contacts rau tooj liab Bars tsis yog tsuas yog ua tam sim no xwb tab sis tseem cuam tshuam ncaj qha rau cov cuab yeej tawg, kev tswj qhov kub thiab txias, thiab kev pab cuam lub neej. Silver Contact Brazed Assemblies ua tau zoo sib npaug ntawm conductivity thiab arc kuj los ntawm metallurgically bonding silver -raws li alloy hu rau ib tug heev conductive tooj liab substrate, ua rau lawv tshwj xeeb tshaj yog haum rau daim ntaub ntawv uas nquag ua hauj lwm los yog loj load fluctuations.
Compared to mechanical pressing or simple welding, brazing creates a continuous and dense metallic bonding layer at the contact interface, significantly reducing contact resistance and improving structural stability.
Application Scenarios: Txhim khu kev ua tau zoo ntawm cov khoom siv hluav taws xob nruab nrab thiab qis qis
Moulded Case Circuit Breakers (MCCBs) thiab Universal Circuit Breakers (ACBs)
Ua hauj lwm raws li cov tub ntxhais tam sim no - nqa cov actuators rau luv luv - tiv thaiv Circuit Court.
AC Contactors
Ua kom muaj kev ncaj ncees ntawm Resistance Projection Welding Silver Tiv tauj qhov chaw ua haujlwm thaum lub sij hawm kaum tawm txhiab qhov qhib thiab kaw.
Industrial Disconnect Switches
Txo busbar kub nce nyob rau hauv siab tam sim no loads los ntawm zoo heev thermal dispersion kev ua tau zoo rau tooj liab Spot Welding Silver Contact.
Rail Transit Control
Lub rooj sib tham nruj automotive- qib hluav taws xob xav tau rau kev co thiab kev poob siab.
Technical nta: Plaub lub peev xwm muab los ntawm Brazing
| Ultra-Low thiab Constant Contact Resistance | Vim hais tias cov txheej txheem brazed yog ib qho kev sib txuas sib txuas txuas ntxiv + cov khoom siv, nws qhov ntim tiv thaiv tsuas yog li 15-20% siab dua li cov tooj liab ntshiab, thiab nws tsis hloov lub sijhawm. Hauv qhov sib piv, qhov sib cuag ntawm cov khoom riveted maj mam nce vim kev co thiab thermal cycling. Rau cov hluav taws xob hluav taws xob, qhov no txhais tau tias qhov ntsuas kub qis dua thiab siab dua qhov ntsuas tam sim no. |
| Withstands Electrodynamic Repulsion ntawm luv -Circuit Current | Thaum lub Circuit Court breaker cuam tshuam qhov luv luv -circuit tam sim no, ib tug loj electrodynamic repulsion yog tsim los ntawm cov tsiv / nyob ruaj ruaj, thiab Resistive Welding Silver Contact yuav thaws. Brazed pob qij txha tuaj yeem tiv taus kev cuam tshuam txog li kaum ntawm g yam tsis muaj delamination-vim cov txheej txheej hlau brazing tau tsim ib daim ntawv cog lus metallurgical nrog rau cov substrate, es tsis yog lub cev sib cuam tshuam. |
| Resistance rau Arc Thermal Shock | The temperature at the centre of an electric arc can reach thousands of degrees Celsius, and heat is rapidly conducted to the AC Resistance Welding Silver Contact. The melting point of the brazed interface (typically >600℃) yog siab dua qhov kub ntawm qhov muag ntawm lub riveted interface, thiab nws tsis muaj cov organic los yog qis dua - melting -point fillers. Peb cov khoom tau pom tias tsis muaj kev tawg lossis tawg tawm hauv cov txheej txheem brazed tom qab 200 qhov kawg kev xeem. |
| Txhawb High Current Nruam Flow | Rau cov contactors nrog qhov ntsuas tam sim no ntawm 250A lossis siab dua, cov hlua tooj liab nws tus kheej tuaj yeem ntsib qhov kub siab. Lub brazed sib koom ua ke, los ntawm kev tshem tawm Hluav Taws Xob Hluav Taws Xob Spot Welding Silver Contact thermal resistance, dhau los ua "tsawg- qhov kub thiab txias" hauv tag nrho cov hluav taws xob hluav taws xob, tiv thaiv kev kub ntxhov thiab kev tiv thaiv ntxov ntxov. |
Design Advantages: Cov ntsiab lus tsim rau kev ntseeg siab thiab kev tsim khoom
Hu rau Hauv qab Cia Channel Tsim
Peb tsim micro-annular grooves los yog radial grooves nyob rau hauv qab nto ntawm cov nyiaj thiab tooj liab vuam khawm tiv tauj. Thaum lub sij hawm brazing, lub molten brazing muab tub lim hlau ntws mus rau hauv grooves, tsim ib tug ob chav kev ruaj ntseg mechanism ntawm mechanical locking thiab metallurgical bonding, thaum tiv thaiv muab tub lim hlau overflow thiab paug ntawm lub chaw ua hauj lwm nto.
Positioning Features ntawm tooj liab sawb
Bosses lossis Countersunk Holes: Cov thawj coj ntiav ntiav (0.1 ~ 0.2mm siab) lossis qhov chaw so ua ntej -fabricated ntawm cov tooj liab sawb, cia li nruab nrab ntawm cov neeg sib cuag tom qab tso, txo cov cuab yeej dependence.
Flow Guides: V-zoo li tus grooves yog machined nyob rau ntawm ntug ntawm lub brazing cheeb tsam los coj cov muab tub lim ntau tshaj cov hlau rau cov uas tsis yog -functional cheeb tsam, tiv thaiv nws los ntawm ntws mus rau qhov chaw ua hauj lwm.
Multi-layer Contact Design
Rau ob npaug -sab contactors, peb tuaj yeem sib txuas ob lub nyiaj sib txuas ntawm ob qhov kawg ntawm tib lub tooj liab. Ib qho kev sib txuas tshwj xeeb ua kom ntseeg tau tias qhov sib luag ntawm cov neeg sib txuas ntawm ob qhov kawg ntawm cov kab nruab nrab yog Tsawg dua lossis sib npaug rau 0.05mm, ua kom yooj yim rau txhua qhov sib dhos thiab kev debugging.
Anti-silver migration ntug:Tawm ntawm 0.3 ~ 0.5mm tooj liab protrusion ntawm qhov sib txuas ntawm Nyiaj rau tooj liab Brazing kom tsis txhob muaj nyiaj los ntawm kev tsiv teb tsaws raws qhov kub thiab txias, uas yuav txo txoj kev nkag mus.
tiv tauj peb
Yog koj tab tom nrhiav ibSilver thiab Copper Welding Button Sib cuagtivthaiv kev daws teeb meem uas tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev hauv lub ntiaj teb tiag -cov xwm txheej hauv ntiaj teb thiab tuaj yeem sib xyaw ua ke nrog kev tsim kom zoo dua qub, peb pab neeg ua haujlwm engineering tuaj yeem muab kev txhawb nqa ntau dua rau koj qhov project.
