Xaiv cov ntaub ntawv tiv tauj rau lub hom phiaj lub hom phiaj fais fab relays ncaj qha dictates hluav taws xob lifespan, tiv thaiv kev ruaj ntseg, thiab arc yaig kuj nyob rau hauv inductive loads. Nyiaj Alloy Hluav Taws Xob Cov Hluav Taws Xob thiab cov nyiaj tin oxide AgSnO2 sawv cev rau cov khoom siv sib txawv uas tau tsim los rau kev hloov pauv tshwj xeeb, xav tau kev ntsuam xyuas meej raws li qhov ceev tam sim no, nce siab siab, thiab thermal shock tsis.
Material Metallurgy thiab Microstructure Fundamentals ntawm Bimetal Rivet Contacts
Nyiaj alloys, feem ntau yog Silver-Nickel AgNi thiab Silver-Copper AgCu, tso siab rau cov kev daws teeb meem ntxiv dag zog lossis nplua-theem faib kom ua tiav cov hluav taws xob conductivity Ntau dua lossis sib npaug li 85% IACS. Raws li ib qho kev sib cuag ntawm Cov Nyiaj Hluav Taws Xob Hluav Taws Xob, AgNi variants muab qhov ruaj khov tsis tshua muaj kev tiv thaiv kev tiv thaiv thiab qhov hluav taws xob tsawg tsawg hauv qab qis-rau- nruab nrab tiv thaiv loads. Txawm li cas los xij, nyob rau hauv kev cuam tshuam hnyav tam sim no, qhov qis melting point ntawm cov nyiaj matrix accelerates cov ntaub ntawv xa mus thiab micro-welding tendencies.
Hloov pauv, Hluav Taws Xob Relay Silver AgSnO2 / Cu Bimetal Rivets txais AgSnO2 ua cov oxide-dispersion-strengthened composite. Fine SnO2 hais yog uniformly embedded nyob rau hauv cov nyiaj matrix ntawm hmoov metallurgy los yog tshuaj synthesis. Thaum raug kub-kub hluav taws xob arcs, lub SnO2 theem ua raws li ib tug nruj thermal skeletal moj khaum, suppressing hydrodynamic hlau ntws thiab inhibiting arc yaig. Cov qauv kev ruaj ntseg no ua rau muaj kev tiv thaiv zoo tshaj plaws thaum hloov cov khoom siv inductive xws li solenoid li qub thiab lub cev muaj zog me me.

Kev ntsuas kev ua tau zoo ntawm Bimetal Rivets Silver Contacts Nyob rau hauv DC thiab AC Switching Loads
Circuit dynamics txiav txim seb cov hlau lossis cov oxide-raws li kev sib xyaw ua tiav lub hom phiaj kev ua haujlwm siab uas tau teev tseg hauv IEC 60947. Raws li ib txwm siv Bi-hlau Silver Contact Point, cov nyiaj alloys ua tau zoo nyob rau hauv huv si, qis-tam sim no teeb liab circuits qhov kev sib cuag bounce yuav tsum nyob twj ywm tsawg heev thiab thawj millivolt poob yog qhov tseem ceeb. Txawm li cas los xij, lawv qhov tsis zoo rau kev tsim cov yeeb yaj kiab sulfide hauv kev lag luam ib puag ncig qhia cov txheej txheem ciam teb siab uas ua rau txo qis kev hloov pauv kev ntseeg siab.
AgSnO2 Cov ntaub ntawv tiv tauj txo qis ib puag ncig sulfur paug thaum xa cov khoom ruaj khov arc extinction. Thaum lub sij hawm caij tsheb kauj vab siab, AgSnO2 nthuav tawm qhov kev kwv yees, maj mam nce hauv kev tiv thaiv tsis yog kev puas tsuaj loj. Qhov kev coj cwj pwm no tiv thaiv kom tsis txhob muaj cua sov ua ntej thaum ntxov nyob rau hauv lub luag haujlwm hnyav contactors thiab high-voltage DC (HVDC) switching architectures.

Manufacturing thiab Fabrication Constraints ntawm Bi-Metal Silver Alloy Contact
Ua kom muaj kev ntseeg siab Bimetal Contact Buttons rau Relays suav nrog cov txheej txheem hlau ua haujlwm siab, suav nrog bimetal txias taub hau, siab zaus brazing, thiab kev tuag stamping. AgNi alloys muaj cov ductility siab, tso cai rau lub taub hau txias deformation ntau tshaj 4: 1 yam tsis muaj ntug tawg. Qhov no tso cai rau tus nqi tsim nyog ntawm bimetal rivets qhov twg lub hau nyiaj yog mechanically kaw rau ntawm lub shank tooj liab.
Manufacturing AgSnO2 Cheebtsam yuav tsum tau tshwj xeeb sintering thiab extrusion tsis vim lub hard oxide theem. Vim tias cov AgSnO2 nyoos tuaj yeem ua rau qis qis qis, Hluav Taws Xob Relay Silver AgSnO2 / Cu Bimetal Rivets nquag siv cov txheej nyias nyias cov ntaub nplaum uas txuas rau lub caij nplooj ntoos hlav tooj dag lossis tooj liab los ntawm kev siv tsis siv neeg lossis laser vuam. Dimensional tolerances mus rau ± 0.005 hli yog tswj xyuas kom ntseeg tau tias qhov sib txawv ntawm qhov sib txawv thaum lub sij hawm sib dhos relay.
