Oct 05, 2026
Tso lus
AgC (silver-graphite) thiab AgNi (nyiaj-nickel) cov ntaub ntawv tiv tauj nyob rau hauv qhov sib txawv ntawm kev hloov kev ntxhov siab hauv cov hluav taws xob me me. AgC cov lus qhia txog kev sib cuag siv graphite los txo kev sib cuag vuam thiab tswj siab -tam sim no arcing, thaum AgNi tiv tauj muab qhov sib npaug zog ntawm cov hluav taws xob conductivity, tiv thaiv kev tiv thaiv, thiab yaig tsis kam rau kev hloov pauv rov qab.
Rau MCB kev tsim qauv ntsuas tawm tsam IEC 60898-1, kev xaiv cov khoom yuav tsum yog raws li qhov luv luv -circuit tam sim no, ntsuas tam sim no, qhov hluav taws xob, lub zog hluav taws xob, hloov zaus, kev sib cuag, lub sijhawm arc, thiab xav tau hluav taws xob endurance-tsis yog cov ntsiab lus nyiaj ib leeg.
Luv-Circuit Vuam ntawm 6–10 kA: Kev Sib cuag tsis ua haujlwm
Thaum lub sijhawm MCB luv - cuam tshuam hauv Circuit Court, cov neeg sib cuag tuaj yeem muaj qhov ceev tam sim no siab heev hauv lub sijhawm luv luv. Qhov kub ntawm qhov sib cuag hauv zos tuaj yeem nce nrawm nrawm, ua rau lub hauv paus melting, hloov khoom siv, thiab kev siv tshuab vuam ntawm cov neeg nyob ruaj khov thiab txav mus.
Cov kev sib cuag yog li ntawd yuav tsum tswj peb qhov sib txawv ntawm qhov sib txawv:
6–10 kA yav tom ntej luv luv-circuit tam sim no: siab tam sim no nce hauv zos Joule cua sov thiab electromagnetic rog.
Arc zog thaum cuam tshuam: ntev arc ncua sij hawm nce kev sib cuag yaig thiab hloov khoom siv.
Tiv tauj siab thiab geometry: tsis txaus siab nce constriction kuj; Lub siab ntau dhau ua rau cov neeg kho tshuab hnav thiab actuator load.
Ib qho kev sib cuag uas tswj xyuas qhov pib tsis zoo tab sis raug kev hloov pauv ntawm cov khoom hnyav tom qab kev cuam tshuam rov qab tuaj yeem ua tsis tiav qhov kev sim ntsuas hluav taws xob uas yuav tsum tau ua.
Hu rau Welding Hauv qab 6–10 kA luv-Circuit Stress
Kev sib cuag welding feem ntau pib ntawm microscopic asperities es tsis yog hla tag nrho thaj chaw sib cuag. Kev siv hluav taws xob tiag tiag tshwm sim los ntawm qee qhov tsawg ntawm cov ntsiab lus hlau constriction.
Kwv yees li kev sib raug zoo ntawm cov cua sov yog:
P=I^2R
qhov twg kuv yog tam sim no, thiab R yog qhov zoo constriction kuj.
Ntawm qhov ua txhaum loj tam sim no, txawm tias qhov nce me me hauv zos tiv thaiv ua rau muaj kev kub ntxhov sai sai. Thaum qhov kev sib cuag sib cuag mus txog qhov kub txaus rau lub zos melting, molten txuas tuaj yeem tsim ntawm ob qhov chaw sib cuag.
Tom qab kev cuam tshuam tam sim no, cov txuas hniav no tuaj yeem ua kom khov thiab kho cov neeg sib cuag ua ke.
IEC 60898-1 Kev Sib cuag-System Requirements
Rau qis -voltage MCBs, IEC 60898-1 txhais cov kev xav tau thiab cov kev sim ntsuas uas suav nrog cov yam ntxwv xws li ntsuas tam sim no, kev ua haujlwm luv luv, thiab hluav taws xob endurance.

Cov kev xav tau ntawm hluav taws xob conductivity yog nruab nrab
Cov khoom siv thauj khoom thiab kev tiv tauj - cov ntaub ntawv qhia yuav tsum tau teev nws tus kheej.
AgC vs. AgNi Procurement ntawm PPAP Theem 3: Kev Ntsuam Xyuas Cov Khoom Muag
Rau kev tsim khoom, cov lus qhia txog kev yuav khoom yuav tsum txhais cov kev ntsuas ntsuas tsis yog tsuas yog hais tias "kev sib cuag nyiaj."
Ib qho kev RFQ yuav tsum muaj xws li:
Tiv tauj cov ntaub ntawv qib
Nominal muaj pes tsawg leeg
Hu rau -cov lus qhia qhov ntev
Cov khoom thauj
Riveting los yog brazing txoj kev
Tiv tauj kuj yuav tsum tau
Luv - qhov ntsuas hluav taws xob
Hluav taws xob endurance phiaj
Dimensional kam rau ua
Nto - kev kho mob yuav tsum tau
Kev tshuaj xyuas txoj kev
Ntim cov cai
Ntau traceability
PPAP Qib 3 qhov yuav tsum tau muaj yog muaj
Ib tus neeg muaj peev xwm MCB nyiaj tiv tauj yuav tsum tuaj yeem txuas cov ntaub ntawv pov thawj, ntau lawm, cov ntaub ntawv siv, thiab cov ntaub ntawv tshuaj xyuas rau kev sib txuas lus tiav.

FAQ: 6–10 kA luv-Circuit thiab AgC/AgNi MCB Kev xaiv
1. Cov khoom siv twg zoo dua rau kev tiv thaiv- vuam MCB tiv tauj ntawm 6–10 kA luv-circuit tam sim no?
AgC feem ntau muab kev tiv thaiv zoo dua - vuam tus cwj pwm vim graphite txo cov hlau nplaum thaum lub sij hawm siab - muaj zog cuam tshuam. AgNi tseem tuaj yeem muab kev tiv thaiv zoo - vuam kev ua tau zoo, tab sis kev xaiv zaum kawg yuav tsum luv luv - Circuit Court validation raws li MCB architecture tshwj xeeb.
2. Puas yog AgC lossis AgNi raug xaiv rau 10,000–20,000 lub voj voog hloov hluav taws xob?
Ob leeg tuaj yeem tsim nyog. AgNi muab qhov muaj zog conductivity- rau- kev sib npaug ntawm kev ua siab ntev, thaum AgC feem ntau xav tias thaum vuam tsis kam muaj qhov tseem ceeb dua. Qhov kev xaiv zaum kawg yuav tsum yog raws li qhov tseeb load, arc zog, thiab IEC 60898-1 endurance xeem.
3. Dab tsi yuav tsum muajMCB silver contacttus neeg muab khoom muab rau PPAP Qib 3?
Ib pob PPAP Qib 3 feem ntau suav nrog cov txiaj ntsig ntawm qhov loj me, cov ntaub ntawv pov thawj, cov txheej txheem ntws, PFMEA, kev tswj hwm txoj kev npaj, MSA, kev tshawb fawb txog kev muaj peev xwm, kev ua tau zoo- cov ntaub ntawv xeem, thiab cov qauv tsim khoom. Paub meej cov neeg siv khoom- cov cai tshwj xeeb ua ntej xa.
