Kev soj ntsuam ntawm Circuit Breaker Silver Contact Materials: Daim ntawv thov yam ntxwv ntawm AgNi, AgSnO₂, thiab AgW Alloys

Hauv qis-voltage fais fab faib tshuab, kev tswj hwm kev lag luam, thiab cov khoom siv hluav taws xob tshiab, cov khoom siv hluav taws xob tiv thaiv hluav taws xob cuam tshuam ncaj qha rau cov khoom siv hluav taws xob, kev muaj peev xwm tawg, thiab lub sijhawm ua haujlwm ntev -. Raws li qhov tseem ceeb ntawm cov khoom siv hluav taws xob, Cov Hluav Taws Xob Cov Hluav Taws Xob Cov Hluav Taws Xob feem ntau yog tsim los ntawm cov khoom siv nyiaj -raws li cov khoom sib xyaw kom sib npaug conductivity, arc tsis kam, thiab vuam tsis kam.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Nyob rau hauv niaj hnub Circuit Court breakers, Silver Contacts nyob rau hauv Breakers tsis yog cov nyiaj ntshiab tab sis yog ib qho kev sib txuas ua ke tsim los ntawm kev sib txuas cov nyiaj nrog cov ntaub ntawv xws li npib tsib xee, tin oxide, thiab tungsten. Cov ntaub ntawv no muaj kev ruaj ntseg ua haujlwm nyob rau hauv siab - zaus hloov, siab - tam sim no surges, thiab luv- Circuit Court tej yam kev mob, thiab yog li ntawd lug siv nyob rau hauv me me Circuit Court breakers, molded case Circuit Court breakers, thiab cua Circuit Court breakers.

 

Structurely, ntau Silver Contact Rivets feem ntau yog tsau rau lub hauv paus tooj liab los ntawm riveting, brazing, los yog txias forging los tsim ib qho kev sib cuag. Vim tias kev sib cuag tau raug rau arc yaig thiab thermal shock nyob rau lub sijhawm ntev, kev xaiv cov khoom siv tsis tsuas yog txiav txim siab conductivity tab sis kuj cuam tshuam rau kev nyab xeeb ntawm tag nrho cov hluav taws xob.

 

Silver (Ag) yog cov khoom tseem ceeb hauv txhua qhov nyiaj -raws li cov ntaub ntawv tiv tauj, muaj hluav taws xob thiab thermal conductivity, txo qhov kub thiab txias thiab tiv thaiv kev tiv thaiv. Txawm li cas los xij, cov nyiaj dawb huv muaj qhov tsis tshua muaj zog thiab nws yooj yim rau melting, deformation, thiab txawm tias cov khoom tsiv teb tsaws nyob rau hauv lub zog arc. Yog li ntawd, cov khoom siv nyiaj hluav taws xob sib txuas feem ntau yog siv rau hauv cov ntawv thov kev lag luam los txhim kho cov khoom siv tshuab.

 

AgNi (silver-nickel alloy) yog ib qho ntawm cov khoom siv hluav taws xob sib txuas ntau tshaj plaws. Qhov sib ntxiv ntawm npib tsib xee txhim kho kev sib cuag hardness thiab hnav tsis kam thaum txo cov khoom tsiv teb tsaws, kom ruaj khov kev sib cuag txawm tias tom qab siv ntev -. AgNi cov ntaub ntawv uas muaj cov ntsiab lus tsis tshua muaj nickel muaj kev ua tau zoo tshaj plaws thiab tsim nyog rau lub sijhawm ntev - cov xwm txheej kev coj ua; cov uas muaj cov ntsiab lus siab nickel muab kev tiv thaiv zoo dua rau vuam thiab tsim nyog rau kev hloov pauv ntau zaus.

 

Vim nws cov nqi ruaj khov thiab kev ua haujlwm zoo ib yam, AgNi cov ntaub ntawv tau siv dav hauv cov khoom siv hluav taws xob hauv tsev, kev tswj hwm kev lag luam, thiab cov pa hluav taws xob tsawg- cov ntawv thov hluav taws xob. Ntau cov khoom siv nyiaj Bimetal Sib cuag kuj tseem siv AgNi system kom sib npaug conductivity thiab lub neej txhua yam.

 

AgSnO₂ (silver tin oxide) yog cov khoom siv tiv thaiv ib puag ncig uas tau pom kev loj hlob sai hauv kev thov hauv xyoo tas los no. Piv nrog rau ib txwm Silver Cadmium Contacts, AgSnO₂ yog cadmium-dawb, muab kev ua haujlwm zoo ib puag ncig, thaum tseem muaj kev tiv thaiv zoo rau arc yaig thiab weldability.

 

AgSnO₂ Kev sib cuag ua tau zoo tshwj xeeb hauv siab -load, siab -inrush- ib puag ncig tam sim no. Thaum lub Circuit Court breaker cuam tshuam ib tug loj tam sim no, cov khoom nto tuav zoo structural stability, txo arc yaig ntawm cov neeg sib cuag. Yog li ntawd, cov khoom siv no tau siv dav hauv kev lag luam hluav taws xob hluav taws xob, kev tiv thaiv lub cev muaj zog, thiab cov khoom siv hluav taws xob tshiab.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Kev ua haujlwm ntawm AgSnO₂ cov ntaub ntawv feem ntau nyob ntawm cov txheej txheem tsim khoom. Lub uniformity ntawm oxide faib ncaj qha cuam tshuam rau kev sib cuag lub neej thiab stability. Tam sim no, ntau qhov kev ua haujlwm siab -Silver Alloy Hluav Taws Xob Sib Txuas Rivets hauv kev lag luam yog tsim los siv cov hmoov metallurgy ua ke nrog cov txheej txheem sintering precision los xyuas kom meej cov qauv hauv cov khoom.

 

Hauv cov hluav taws xob hluav taws xob siab dua, AgW (nyiaj tungsten) thiab AgWC (nyiaj tungsten carbide) nthuav tawm cov kev ua haujlwm zoo dua. tungsten cov ntaub ntawv muaj cov ntsiab lus melting siab heev, muaj peev xwm tiv taus siab -kub arcs tsim nyob rau hauv luv luv -circuit tam sim no, thiab yog li no feem ntau siv nyob rau hauv cua Circuit Court breakers, siab -voltage switches, thiab hnyav- cov khoom siv ua haujlwm.

 

AgW cov ntaub ntawv muaj qhov muaj zog heev tiv thaiv melting, tswj cov khoom qis txawm tias nyob rau hauv siab - zog arc ib puag ncig. AgWC txuas ntxiv txhim kho hardness thiab hnav tsis kam, tso cai rau kev sib cuag kom muaj kev ruaj khov zoo nyob rau hauv cov xwm txheej tsis tu ncua. Txawm li cas los xij, vim nws qhov hardness siab, nws cov txheej txheem nyuaj yog nce ntxiv, yuav tsum tau ua kom muaj kev ua haujlwm siab hauv txias- ua cov txheej txheem hlau thiab pwm.

 

Dhau li ntawm cov nyiaj tungsten, AgC (silver graphite) cov ntaub ntawv feem ntau yog siv los tiv thaiv kev sib cuag adhesion. Graphite txo qhov nyiam ntawm cov khoom siv, txo qhov kev pheej hmoo ntawm kev sib cuag vuam hauv qee qhov tshwj xeeb hloov khoom siv. Cov ntaub ntawv no feem ntau yog siv rau hauv cov qauv hluav taws xob tiv tauj uas xav tau los tiv thaiv - adhesion zog.

 

Nyob rau hauv cov nqe lus ntawm kev tsim cov txheej txheem, cov txheej txheem tseem ceeb tam sim no hauv kev lag luam muaj xws li hmoov metallurgy, kub nias, sintering, thiab txias txoj kev sib cuag. Lub taub hau txias zoo txhim kho qhov sib xws thiab kev ua haujlwm ntau lawm; yog li ntawd, ntau tus mob khaub thuas- taub hau hluav taws xob tiv tauj yog pawg- tsim los siv txoj kev no.

 

Rau kev sib cuag bimetallic, bimetallic resistors feem ntau yog tsim los ntawm cov nyiaj alloy tiv tauj txheej thiab tooj liab substrate, uas tuaj yeem txo cov nqi khoom thaum tswj xyuas qhov zoo. Hom qauv no yog dav siv nyob rau hauv relays, contactors, thiab low-voltage circuit breakers.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Nrog rau kev txhim kho ntawm siab -voltage, miniaturized, thiab cov khoom siv hluav taws xob tshiab, cov kev xav tau ntawm cov khoom siv hluav taws xob tiv tauj cov ntsiab lus nyiaj tau nce ntxiv. Cov kev sib cuag niaj hnub no tsis yog tsuas yog yuav tsum muaj kev tiv thaiv qis xwb tab sis kuj zoo heev oxidation kuj thiab thermal stability kom txo tau oxidized hluav taws xob tiv tauj teeb meem tom qab ua haujlwm ntev -.

 

Tam sim no, ntau thiab ntau cov tuam txhab hluav taws xob tiv tauj tau txais kev siv lub tshuab sintering, precision riveting, thiab cov thev naus laus zis hauv online los txhim kho cov khoom sib xws thiab kev cia siab ntev ntev. Nyob rau tib lub sijhawm, cov kws tshaj lij hluav taws xob tiv tauj cov tuam txhab tseem tau them nyiaj ntau dua rau kev tsim cov khoom tsim kom zoo kom tau raws li qhov kev thov rau siab - kev sib cuag hauv cov teb xws li lub zog tshiab, lub zog khaws cia, thiab cov phiajcim ntse.

 

Feem ntau, cov nyiaj sib txawv -raws li cov ntaub ntawv tiv tauj txhua tus muaj lawv tus yam ntxwv. AgNi yog tsim rau cov khoom siv hluav taws xob qis qis, AgSnO₂ sib npaug ib puag ncig kev tiv thaiv thiab arc tsis kam, thaum AgW thiab AgWC yog tsim rau siab - fais fab kev lag luam daim ntawv thov. Tsim nyog xaiv ntawmsilver point tiv taujcov ntaub ntawv tuaj yeem tsis tsuas yog txuas lub neej kev pab cuam ntawm Circuit Court breakers tab sis kuj ua kom muaj kev nyab xeeb thiab ruaj khov ntawm tag nrho cov hluav taws xob.
