Hauv kev tswj hluav taws xob niaj hnub thiab lub zog hluav taws xob, kev ua haujlwm ntawm cov khoom siv hluav taws xob sib txuas ncaj qha txiav txim siab txog kev ntseeg siab, kev ua neej nyob, thiab kev nyab xeeb ntawm cov khoom siv. Raws li cov khoom siv hluav taws xob tseem ceeb, Nyiaj hluav taws xob tiv tauj tau ntev dhau los ntawm nruab nrab - mus rau - siab - kawg switchgear lag luam vim lawv qhov kev ua tau zoo tag nrho. Los ntawm cov khoom siv hluav taws xob hauv tsev mus rau cov hluav taws xob hluav taws xob hauv tsev, los ntawm cov teeb liab me me mus rau siab -cov khoom siv hluav taws xob muaj peev xwm, Cov Khoom Siv Nyiaj Txiag tsis tu ncua ua tau raws li cov kev xav tau hloov zuj zus ntxiv los ntawm cov khoom siv tshiab thiab kev ua kom zoo dua qub. Kab lus no tau tshuaj xyuas cov khoom siv, qhov zoo ntawm kev ua haujlwm, thiab cov ntawv thov raug siv ntawm Silver Alloy Rivets, muab kev siv rau kev xaiv kev lag luam.
Tus nqi tseem ceeb ntawm Pure Silver Contacts stems los ntawm nws cov khoom tshwj xeeb physicochemical. Ua ntej, cov nyiaj muaj qhov qis tshaj plaws ntawm tag nrho cov hlau (tsuas yog 1.59 μΩ·cm ntawm 20 degree), kom ntseeg tau tias lub zog poob qis thaum tam sim no ntws. Thib ob, txawm tias cov nyiaj oxide (Ag₂O) tsim rau saum npoo, nws tseem tuav tau zoo conductivity thiab tsis tsim ib qho thaiv thaiv zoo li tooj liab oxides. Qhov tseem ceeb tshaj plaws, qhov kub thiab txias tau tsim thaum lub sijhawm qhib thiab kaw tuaj yeem ncav cuag tshaj 2000 degree, thaum nyiaj thiab nws cov alloys zoo tiv thaiv thermal yaig thiab vuam, ua kom ruaj khov rau ntau txhiab lossis ntau pua txhiab lub voj voog. Vim li no, txawm tias nws tus nqi siab dua, cov khoom siv nyiaj dawb huv tseem tsis tau hloov pauv hauv cov ntawv qis -tam sim no, siab - daim ntawv thov kev ntseeg siab.
Txawm li cas los xij, cov nyiaj dawb huv muaj qhov tsis tshua muaj zog thiab txwv tsis pub siv vuam, ua rau nws tsis haum rau nruab nrab - mus rau siab - daim ntawv thov. Yog li ntawd, kev lag luam tau tsim ntau yam nyiaj -raws li kev sib xyaw thiab alloy tshuab kom ua tiav qhov sib npaug ntawm kev ua tau zoo thiab tus nqi. Tam sim no, cov khoom lag luam tseem ceeb tau muab faib ua peb pawg:
Thawj qeb yog Silver alloys hu, feem ntau sawv cev los ntawm Silver nickel khoom tiv tauj thiab Silver cadmium oxide khoom tiv tauj. Silver-nickel cov ntaub ntawv (xws li Ag-10Ni) tau ntxiv dag zog los ntawm nickel particle dispersion, txhim kho kev hnav tsis kam thiab arc tsis kam, ua rau lawv tsim nyog rau kev siv nyiaj ntau rau kev sib txuas lus. Thaum nyiaj cadmium oxide (Ag-CdO) ib zaug tau siv dav vim nws cov khoom zoo tshaj plaws arc-quenching, nws tau maj mam hloov los ntawm cov kev hloov hauv ib puag ncig ntau dua vim yog ib puag ncig toxicity ntawm cadmium.
Cov qeb thib ob yog tam sim no muaj ntau tshaj plaws Silver tin oxide khoom tiv tauj. Los ntawm cov txheej txheem oxidation sab hauv, nano-sized SnO₂ hais yog sib npaug ntawm cov nyiaj matrix, ua kom ruaj khov, tawg, muaj zog. Ib qho qauv tsim, xws li Ag-8SnO₂, muaj kev tiv thaiv qis dua 2.5 μΩ·cm, muab ntau tshaj peb npaug ntawm kev tiv thaiv - vuam kev ua tau zoo ntawm cov nyiaj ntshiab, thiab tsis yog - tshuaj lom thiab ib puag ncig zoo. Cov txheej txheem ternary ntau dua (xws li Ag-SnO₂-In₂O₃) ntxiv txo kev tiv thaiv kev tiv thaiv los ntawm kev qhia txog indium oxide, uas ua rau 15-20℃txo kev khiav hauj lwm kub nce. Qhov no ua rau lawv tshwj xeeb tshaj yog haum rau cov ntawv thov nrog kev tswj xyuas nruj, xws li Silver contacts rau MCCBs.
Cov qeb thib peb suav nrog cov ntaub ntawv tshwj xeeb rau siab-voltage, siab- daim ntawv thov tam sim no-Silver tungsten. Txawm hais tias tsis tau teev nyob rau hauv cov ntsiab lus, nws cov kev xav tau tsim nyog xav txog. Nyob rau hauv cov ntsiab lus tseem ceeb uas twb muaj lawm, Silver zinc oxide khoom tiv tauj, raws li cov khoom siv zoo ib puag ncig, tseem maj mam nkag mus rau hauv kev ua lag luam. Thaum nws cov conductivity qis dua me ntsis ntawm cov nyiaj tin oxide, nws pom zoo arc tsis kam nyob rau hauv tshwj xeeb AC loads thiab tej zaum yuav tau txais ib qho chaw nyob rau hauv lub lag luam yav tom ntej rau Silver hu rau breakers.
Ntawm cov ntawv thov, cov khoom siv sib txawv muaj qhov ua tau zoo sib txawv rau Silver Alloy Contacts. Piv txwv li, Silver contacts rau cov keyboards feem ntau ua haujlwm ntawm qhov qis qis qis dua 10A thiab tuaj yeem ua los ntawm cov nyiaj ntshiab lossis tsis tshua muaj alloying, hais txog kev coj ua thiab cov lus teb ceev; thaum Alloy Silver contacts rau relays yuav tsum sib npaug ntawm kev hloov zaus thiab lub neej ntev, ua rau nyiaj -nickel lossis silver- tin oxide zoo dua; Raws li rau MCCBs (cov ntaub ntawv molded Circuit Court breakers) thiab cua Circuit Court breakers, cov khoom siv nyiaj yuav tsum tau muaj kev cuam tshuam zoo nyob rau hauv luv luv -circuit tam sim no surges, ua siab SnO₂ ntsiab lus silver- tin oxide los yog composite multiphase cov ntaub ntawv uas nyiam.
Nws yog ib nqi sau cia hais tias lub geometry ntawm nyiaj hluav taws xob tiv tauj yog qhov tseem ceeb sib npaug. Cov khoom sib tiv tauj muaj txoj kab uas hla ntawm 1 thiab 5 hli thiab thicknesses ntawm 0.3 thiab 1.2 hli. Optimized hu rau siab faib los ntawm kheej kheej, planar, los yog lub xub pwg nyom lug ua rau kom lub zoo conductive cheeb tsam, yog li txo qhov kev tiv thaiv tiv thaiv thiab localized kub nce. Ua ke nrog precision riveting los yog vuam txheej txheem, cov khoom xws li nyiaj npib tsib xee hu thiab Silver Tin Oxide hu tuaj yeem muab tso rau hauv cov rivets sib xyaw, nrhiav kev siv dav hauv kev tswj hwm, tshiab lub zog them pawg, thiab cov phiaj ntse ntse.
Saib tom ntej, nrog rau kev nce qib ntawm "dual-carbon" cov hom phiaj thiab kev siv hluav taws xob nrawm, kev txwv rau cov hlau hnyav- muaj cov ntaub ntawv xws li Silver Cadmium Oxide kev sib cuag yuav nruj dua, ua rau kev tshawb fawb txuas ntxiv zuj zus thiab siv cov kev sib cuag ntawm cov nyiaj oxide ib puag ncig. Nyob rau tib lub sijhawm, cov thev naus laus zis tshiab xws li nano- hloov kho, gradient qauv, thiab microtexturing saum npoo yuav ntxiv dag zog rau cov kev pabcuam kev txwv ntawm cov nyiaj hluav taws xob tiv tauj.
Zuag qhia tag nrho,hluav taws xob tiv taujtau hloov zuj zus los ntawm ib qho - cov ntaub ntawv kev daws teeb meem rau ntau -system, multi-functional engineering solutions. Los ntawm kev xaiv cov khoom siv tshawb fawb thiab kev sib txuam nrog cov xwm txheej ntawm daim ntawv thov, tsis yog tsuas yog cov cuab yeej siv tau ntev thiab kev siv hluav taws xob txhim kho, tab sis kev nyab xeeb hluav taws xob kuj tuaj yeem ua kom ntseeg tau. Nyob rau hauv tus txheej txheem ntawm kev hloov siab -kev tsim khoom kawg rau siab- kev txhim kho zoo, siab -kev ua tau zoo nyiaj-raws li cov khoom siv hluav taws xob tiv tauj yuav txuas ntxiv mus ua lub luag haujlwm tseem ceeb.
Yog tias koj xav tau cov lus qhia txog kev siv cov khoom sib txawv ntawm cov khoom siv sib txuas hauv cov khoom siv hluav taws xob tshwj xeeb lossis kev sib piv ntawm cov txheej txheem, thov koj xav tiv tauj peb.
