Kev Tshawb Fawb Txog Kev Sib Txuas Sib Txuas Cov Khoom Siv thiab Lifespan

Relays yog ib qho ntawm cov khoom siv tswj hwm feem ntau hauv cov uas tsis yog - cov txheej txheem tswj kev tswj hwm tus kheej, lub tshuab hluav taws xob tswj, thiab cov khoom siv hauv tsev. Lub hauv paus ntawm relay kev ua tau zoo nyob hauv nws qhov kev sib cuag. Kev xaiv cov ntaub ntawv sib cuag thiab lawv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob sib txuas ncaj qha txiav txim siab qhov kev ntseeg tau ntawm cov relay, txij nkawm lub voj voog, thiab kev ruaj ntseg ntawm tag nrho cov kab ke. Kev xaiv tsim nyog ntawm cov ntaub ntawv tiv tauj thiab cov qauv tsim pab txo qis cov khoom siv tsis ua haujlwm thiab cov nqi kho mob.

 

 

Relay lifespan feem ntau muab faib ua ob pawg: txhua yam lifespan thiab hluav taws xob lifespan.

 

Mechanical lifespan yog hais txog tus naj npawb ntawm kev ua haujlwm rov ua dua los ntawm kev ua haujlwm ib leeg nyob rau hauv tsis muaj -load tej yam kev mob, feem ntau ncav cuag lab lossis ntau lab lub sijhawm. Hluav taws xob lifespan, ntawm qhov tod tes, hais txog tus naj npawb ntawm lub sij hawm cov neeg sib cuag ua tiav kev hloov pauv thiab tswj kev ua haujlwm ib txwm muaj nyob rau hauv cov xwm txheej ntsuas, thiab feem ntau qis dua li cov neeg kho tshuab lifespan.

 

Qhov kev cia siab ntawm hluav taws xob lub neej ntawm qhov dav dav - lub hom phiaj relays thiab lub hwj chim relays feem ntau tsis muaj tsawg dua 100,000 cycles, tab sis tus nqi no yog nyob ntawm qhov kev ua haujlwm tshwj xeeb. Thaum cov kev sib cuag ua haujlwm nyob rau hauv cov xwm txheej hauv qab qhov ntsuas, lawv cov hluav taws xob tiag tiag tuaj yeem txuas ntxiv ntau zaus. Piv txwv li, siab - cov neeg nyob tam sim no muaj peev xwm txo qis lub zog arc thiab cov khoom siv qeeb qeeb thaum hloov cov khoom siv me me, yog li ua tiav lub neej nyob hauv ntau lab lub voj voog.

 

Qhov kawg ntawm hluav taws xob lub neej feem ntau tshwm sim los ntawm cov kev ua tsis tiav hauv qab no: Cov khoom siv tsiv teb tsaws tshwm sim nyob rau hauv rov qab arcing, ua rau vuam los yog adhesion; Cov khoom hnyav poob los ntawm kev sib cuag nto spatter lossis ablation tiv thaiv kev tiv thaiv hluav taws xob ruaj khov; Kev tiv thaiv tsis tu ncua nce ntxiv, dhau ntawm qhov kev tso cai ntau yam.

 

Hauv kev siv tshuab ua haujlwm, kev sib cuag lub neej tuaj yeem txuas ntxiv tau zoo los ntawm kev tsim qauv ntawm cov ntaub ntawv sib cuag, kev sib tiv tauj, thiab kev ntsuas arc cuam tshuam.

 

 

Relay hu tuaj yeem siv ntau yam hlau thiab alloys. Cov khoom sib txawv muaj qhov sib txawv tseem ceeb hauv kev coj ua, arc tsis kam, weldability, thiab hnav tsis kam. Cov ntaub ntawv muaj xws li ib qho -hlau hu, cov khoom sib txuas, thiab cov qauv bimetallic, xws li Bimetal Silver Contacts, Bimetal Contact Rivets, thiab Bimetallic Silver Contacts, dav siv hauv kev lag luam relays thiab fais fab relays.

 

Hauv nruab nrab - mus rau - cov ntawv thov tam sim no siab, nyiaj - cov ntaub ntawv sib xyaw yog cov kev xaiv tseem ceeb, ua tiav qhov sib npaug zoo ntawm kev coj ua thiab arc yaig tsis kam. Cov ntaub ntawv no feem ntau muaj nyob rau hauv daim ntawv ntawm Composite Contacts lossis Precision Electrical Contacts, tsim los ntawm cov hmoov metallurgy lossis cov txheej txheem txias.

 

 

1. Silver Cadmium Oxide (AgCdO)

Silver cadmium oxide tau ntev lawm ib yam khoom siv rau nruab nrab - mus rau - siab tam sim no relay hu. Cov khoom siv no siv cov hmoov metallurgy kom sib npaug ntawm cov nyiaj thiab cadmium oxide, ua ke ze ntawm - cov khoom siv hluav taws xob ntshiab nrog cov vuam zoo heev. Nws qhov zoo muaj xws li:

 

Nyob rau hauv arcing, cadmium oxide zoo inhibits cov khoom tsiv teb tsaws;

Nws muaj qhov zoo arc-extinguishing peev xwm, txo qhov kev pheej hmoo ntawm kev sib cuag adhesion;

Nyob rau hauv qhov tsim nyog kev sib cuag, qhov kev tiv thaiv kuj tseem ruaj khov.

 

Feem ntau, cov ntsiab lus cadmium oxide hauv AgCdO yog nyob nruab nrab ntawm 10% thiab 15%. Raws li cov ntsiab lus nce, qhov vuam tsis kam txhim kho, tab sis cov ductility thiab txias ua hauj lwm zog txo raws li. Yog li, cov khoom siv no feem ntau siv rau hauv cov qauv xws li Bimetal Rivet Rau Relays kom sib npaug ntawm kev ua haujlwm thiab hluav taws xob ua haujlwm.

 

2. Silver Tin Oxide thiab Silver Indium Tin Oxide (AgSnO, AgInSnO)

Nrog rau cov kev cai nruj ib puag ncig ntawm cov ntaub ntawv cadmium, nyiaj tin oxide thiab nyiaj indium tin oxide tau maj mam dhau los ua lwm txoj hauv kev tseem ceeb rau AgCdO. Cov ntaub ntawv no muaj zog dua thiab zoo solderability, ua rau lawv tshwj xeeb tshaj yog haum rau cov ntawv thov uas muaj qhov tseem ceeb surge tam sim no thiab tsis tshua muaj zog - xeev tam sim no, xws li filament loads los yog inductive loads.

 

Muab piv rau AgCdO, cov ntaub ntawv no muaj qhov ntim siab dua me ntsis, tab sis lawv muaj kev ntseeg tau zoo hauv tsheb relays thiab DC systems, tshwj xeeb tshaj yog tsim rau siab - kev ntseeg siab tiv tauj cov qauv xws li hloov cov nyiaj sib cuag thiab cov nyiaj ruaj khov.

 

 

Cov nyiaj ntshiab muaj qhov siab tshaj plaws hluav taws xob thiab thermal conductivity ntawm tag nrho cov hlau, tsis tshua muaj kev sib cuag tsis zoo, thiab tus nqi tswj tau; yog li, nws yog dav siv nyob rau hauv silver hluav taws xob tiv tauj. Txawm li cas los xij, nws qhov tsis zoo suav nrog kev ua rau cov sulfidation, nto dulling, thiab ntev - lub sij hawm ruaj khov raug txwv los ntawm ib puag ncig.

 

Nyiaj- tooj liab alloys, los ntawm kev qhia cov tooj liab, txhim kho hnav tsis kam thiab txo weldability, ua rau lawv haum rau nruab nrab- daim ntawv thov tam sim no.

 

Silver- cov ntaub ntawv tungsten muaj cov ntsiab lus melting siab heev thiab arc tsis kam, tab sis yuav tsum tau muaj kev sib cuag siab thiab muaj kev tiv thaiv siab, ua rau lawv feem ntau siv rau hauv siab - cuam tshuam cov ntawv thov xws li zawv zawg hluav taws xob tiv tauj lossis lub nplhaib ntiv nplhaib.

 

Silver-nickel cov ntaub ntawv zoo txhim kho arc yaig tsis kam thaum tuav ze - cov khoom siv nyiaj ntshiab.

 

Silver- cov ntaub ntawv palladium muaj qhov tawv tawv thiab hnav tsis tshua muaj, tab sis kim dua, feem ntau yog siv rau hauv cov khoom siv hluav taws xob nrog cov kev xav tau siab heev.

 

Silver-cov tshuab tooj liab pom zoo corrosion kuj nyob rau hauv qis- tam sim no circuits, ua rau lawv haum rau lub teeb -load daim ntaub ntawv xws li caij nplooj ntoos hlav hluav taws xob tiv tauj.

 

 

Cov neeg sib txuas lus niaj hnub no feem ntau siv cov qauv bimetallic lossis cov qauv sib xyaw, xws li Bimetal Contacts Ag / Cu, Cold Headed Bimetal Contacts, thiab Bimetallic Rivet Contacts. Cov qauv no ua tiav qhov zoo sib npaug ntawm tus nqi, conductivity, thiab lifespan los ntawm kev faib cov khoom ntawm cov khoom siv hluav taws xob thiab cov txheej txheem ua haujlwm.

 

Hauv kev siv cov tswv yim, kev xaiv cov ntaub ntawv tiv tauj tsis yog nyob ntawm qhov ntsuas tam sim no nkaus xwb tab sis kuj tseem yuav tsum tau ua tib zoo xav txog cov khoom thauj khoom (tiv taus, inductive, capacitive), kev khiav hauj lwm voltage, ib puag ncig, thiab kev cia siab rau lub neej. Rau siab -txoj kev ntseeg siab, ntxiv rau kev xaiv cov khoom siv, feem ntau yuav tsum xav txog qhov tsim nyog sib cuag, tsim kev sib cuag, thiab arc- cov tswv yim tua hluav taws.
 

 

Relay tiv taujyog cov khoom tseem ceeb hauv cov tshuab hluav taws xob feem ntau ua rau tsis ua haujlwm, thiab lawv cov khoom siv ncaj qha txiav txim siab lub neej hluav taws xob ntawm lub relay thiab kev ntseeg siab ntawm qhov system. Los ntawm kev tshawb fawb xaiv cov ntaub ntawv sib cuag, rationally txuam load cov yam ntxwv, thiab txais yuav mature bimetallic los yog composite hu lug, lub lifespan ntawm relays yuav ho ncua. Nrog rau txoj kev loj hlob ntawm lub zog tshiab, tsheb hluav taws xob, thiab kev lag luam automation, qhov kev thov rau siab - kev sib cuag hluav taws xob thiab kev sib cuag hlau zoo yuav loj hlob mus ntxiv, thiab kev sib cuag cov khoom siv thev naus laus zis yuav txuas ntxiv mus rau kev ntseeg siab dua thiab kev phooj ywg ib puag ncig.
