Kev ua tau zoo sib txawv ntawm cov nyiaj alloys thiab tooj liab alloys

Contactor hu yog cov khoom siv tseem ceeb rau kev sib txuas thiab kev sib txuas ntawm cov kab hluav taws xob. Lawv cov khoom siv ncaj qha txiav txim siab tag nrho cov kev ua tau zoo ntawm cov cuab yeej hauv cov ntsiab lus ntawm kev ruaj ntseg conductivity, thermal tswj, arc yaig, thiab lub neej txhua yam. Hauv kev tsim hluav taws xob tam sim no thiab hluav taws xob faib hluav taws xob, cov ntaub ntawv tseem ceeb ntawm kev sib cuag feem ntau suav nrog nyiaj -raws li alloys thiab tooj liab-raws li alloys. Qhov txawv ntawm lawv txoj kev ua tau zoo yog qhov tseem ceeb qhia txog kev lag luam engineering- tawm ntawm "kev ntseeg siab siab" thiab "tus nqi- kev taw qhia ua tau zoo." Qhov sib txawv no kuj tseem siv tau rau ntau hom kev sib cuag hluav taws xob, suav nrog kev sib txuas sib txuas thiab ntau- txheej bimetallic contacts (Ag/Cu).

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Los ntawm qhov kev xav ntawm conductivity, nyiaj alloys muaj cov conductivity siab heev, nrog rau tus qauv conductivity nce los yog ncav cuag 100% IACS. Txawm tias tom qab alloying, lawv tswj tau qhov kev sib cuag tsis tshua muaj qib, yog li tiv thaiv qhov kub thiab txias nce nyob rau hauv siab tam sim no lossis siab - zaus hloov cov xwm txheej. Thaum tooj liab alloys muaj conductivity ze rau nyiaj nyob rau hauv lawv cov ntshiab lub xeev, lawv conductivity ho txo ​​nyob rau hauv cov ntaub ntawv siv vim alloying thiab oxidation. Yog li ntawd, nyob rau hauv xav tau scenarios, nyiaj hluav taws xob tiv tauj los yog noble hlau kev daws teeb meem raws li precious hlau systems feem ntau nyiam.

 

Nyob rau hauv cov nqe lus ntawm corrosion kuj, nyiaj cov ntaub ntawv muaj ib tug tseem ceeb kom zoo dua. Cov oxide txheej tsim los ntawm cov nyiaj hauv huab cua lossis qhov chaw ntub dej khaws cia qee qhov kev coj ua, ua kom muaj kev ruaj ntseg ntawm kev sib cuag. Tooj liab, txawm li cas los xij, yooj yim tsim cov txheej txheem tooj liab oxide tsis zoo nyob rau hauv ib puag ncig zoo sib xws, ua rau muaj kev tiv thaiv ntau ntxiv thiab ua rau muaj kev kub ntxhov ntau ntxiv. Yog li ntawd, nyob rau hauv siab - av noo, muaj kuab paug heev, los yog corrosive cua, nyiaj -raws li systems los yog Noble Precious Metals- zoo li cov ntaub ntawv yog ntau haum rau engineering daim ntaub ntawv, thaum tooj liab - cov ntaub ntawv raws li feem ntau yuav tsum tau plating los yog nto kho kom ncua tsis ua hauj lwm.

 

Kev tiv thaiv - vuam muaj peev xwm yog qhov qhia tau tseem ceeb ntawm kev ntseeg siab ntawm cov ntaub ntawv tiv tauj hauv arc ib puag ncig. Nyiaj alloys, los ntawm kev sib xyaw cov ntsiab lus xws li npib tsib xee thiab tin oxides, tuaj yeem txhim kho siab - qhov kub thiab txias ntawm cov qauv kev ruaj ntseg thiab txo qhov kev pheej hmoo ntawm molten adhesion, uas yog ib qho laj thawj tseem ceeb rau lawv siv dav hauv kev tswj lub cev muaj zog thiab siab -load switching equipment. Cov qauv tsim muaj xws li Bimetal Contact Rivets thiab Bimetallic Silver Contacts, ua tiav qhov sib npaug ntawm kev coj ua thiab kev tiv thaiv- vuam kev ua tau zoo los ntawm cov qauv sib xyaw. Hauv qhov sib piv, cov ntaub ntawv tooj liab soften yooj yim dua ntawm qhov kub thiab txias, thiab oxide txheej exacerbates arc yaig, yog li ua rau qhov tshwm sim ntawm fusion vuam.

 

Nyob rau hauv cov nqe lus ntawm hnav tsis kam thiab txhua yam muaj zog, tooj liab alloys feem ntau pom muaj zog dua hardness thiab deformation tsis kam, ua rau lawv haum rau cov kev siv uas muaj siab mechanical kev nyuaj siab los yog nquag ua hauj lwm. Silver alloys, ntawm qhov tod tes, txhim kho qhov tawv tawv los ntawm kev sib zog ua kom muaj zog lossis sib xyaw tsim. Piv txwv li, cov qauv sib txuas sib txuas tsim los siv cov txheej txheem Cold Headed Bimetal Contacts tuaj yeem txhim kho hnav tsis kam thaum tswj kev ua haujlwm. Hauv zawv zawg lossis tig hluav taws xob sib txuas, xws li Sliding Electrical Contacts thiab Slip Ring Contacts, hnav tsis kam thiab conductivity stability ntawm cov khoom yuav tsum raug txiav txim siab.

 

Los ntawm tus nqi saib, nyiaj, raws li ib tug zoo precious hlau, yog ho kim dua tooj liab. Yog li ntawd, silver alloy hu yog tsuas yog siv nyob rau hauv industrial teb nrog siab kev cia siab rau. Tooj-raws li cov ntaub ntawv, vim lawv cov nqi kom zoo dua, tseem muaj kev lag luam dav hauv qis-tam sim no, tsawg- cov ntawv thov zaus, xws li cov khoom siv hluav taws xob sib txuas lossis tooj liab hluav taws xob cov khoom siv hauv lub teeb -load systems. Hauv qee qhov qauv tsim, nyiaj -coated tooj liab qauv kuj tau siv los ua kom muaj qhov sib npaug ntawm tus nqi thiab kev ua haujlwm.

 

Hauv kev xaiv cov ntawv thov tshwj xeeb, nyiaj -raws li kev sib cuag systems, xws li Bimetallic Contact Rivets lossis Bimetal Rivet Rau Relays, feem ntau nyiam rau qhov siab tam sim no, siab zaus, thiab ib puag ncig hnyav kom ntseeg tau ntev - lub sijhawm ua haujlwm ruaj khov. Hauv qis -load lossis nqi- cov xwm txheej tseem ceeb, tooj liab- raws li kev sib cuag lossis yooj yim Hloov Nyiaj Sib cuag cov qauv tuaj yeem siv los ua lwm txoj hauv kev. Rau cov khoom siv precision lossis siab -kawg daim ntawv thov, Precision Electrical Contacts thiab ntau- cov khoom sib xyaw tsim tau ua haujlwm kom ua tau raws li qib siab ntawm cov khoom siv hluav taws xob.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Hauv cov ntsiab lus, qhov sib txawv ntawm cov nyiaj thiab tooj liab alloys hauv contactor hu rau daim ntawv thov yog qhov tseem ceeb ntawm kev lag luam tawm - tawm ntawm cov khoom siv lub cev thiab cov nqi engineering. Raws li cov khoom siv hluav taws xob hloov mus rau qhov muaj zog dua thiab muaj kev ntseeg siab dua, kev sib txuas lus sib txuas raws li cov txheej txheem hlau muaj txiaj ntsig, xws liBimetal Electronic Contactsthiab ntau- txheej Bimetal Rivet Contacts, tau dhau los ua thev naus laus zis. Tib lub sijhawm, cov khoom siv cov khoom siv tau maj mam dhau los ua tshwj xeeb, tso siab rau Precious Metal Suppliers uas muaj peev xwm tswj tau zoo los muab cov kev daws teeb meem zoo sib xws.
