Hauv kev tswj xyuas hluav taws xob niaj hnub thiab kev ntsuas ntse, cov khoom sib nqus latching relays, nrog rau lawv cov yam ntxwv tshwj xeeb bistable thiab ultra- siv hluav taws xob tsawg, tau dhau los ua cov khoom tseem ceeb hloov cov khoom siv hluav taws xob sib nqus. Tshwj xeeb tshaj yog nyob rau hauv cov phiajcim ntse, kev lag luam automation, thiab cov tshuab hluav taws xob tshiab, hom relay no tsis tsuas yog daws qhov teeb meem ntawm coil overheating los ntawm kev siv lub zog ntev, tab sis kuj ua tiav kev kaw haujlwm zoo thiab hloov pauv ntawm lub xeev Circuit Court los ntawm kev sib koom tes ntawm cov hlau nplaum ruaj khov thiab cov tshuab electromagnetic. Kev nkag siab tob txog nws cov qauv kev khiav hauj lwm, cov yam ntxwv ntawm cov qauv, thiab daim ntawv thov scenarios yog qhov tseem ceeb rau kev txhim kho qib tsim thiab kev ntseeg siab ntawm cov tshuab hluav taws xob.
Bistable Mechanism thiab Magnetic Circuit Design Principple
Lub hauv paus ntsiab lus ua haujlwm tseem ceeb ntawm kev sib nqus latching relay yog raws li lub tshuab bistable. Tsis zoo li ib txwm relays uas yuav tsum tau tas li energization los tswj lawv cov kev koom tes nyob rau hauv lub xeev, ib tug sib nqus latching relay integrates ib tug siab -kev ua tau zoo mus tas li hlau nplaum. Lub xeev "qhib" thiab "kaw" ntawm nws cov kev sib cuag yog tag nrho tswj los ntawm cov hlau nplaum tas li tsim los ntawm cov hlau nplaum tas mus li. Thaum lub coil tsis muaj zog, lub armature, nyob rau hauv lub zog ntawm cov hlau nplaum ruaj khov lub zog sib nqus, tuaj yeem nyob ruaj khov nyob rau hauv ib txwm qhib lossis ib txwm kaw txoj haujlwm yam tsis tas siv hluav taws xob.
Lub xeev hloov pauv nyob ntawm qhov cuam tshuam tam sim ntawm electromagnetic induction. Thaum lub ntsuas hluav taws xob siv qhov zoo DC mem tes ntawm qhov dav dav rau lub kauj, lub electromagnetic teb uas tsim los ntawm lub kauj thiab cov hlau nplaum ntawm cov hlau nplaum ruaj khov superimpose los ua ib qho chaw sib nqus zoo sib nqus, tsav lub armature txav tawm tsam txhua yam tshuaj tiv thaiv quab yuam, ua rau cov neeg raug kaw (set). Thaum cov mem tes xaus, lub tshuab hluav taws xob electromagnetic ploj, thiab lub armature yog ruaj khov rau hauv txoj hauj lwm tshiab hauv qab lub zog sib nqus ntawm cov hlau nplaum ruaj khov. Txhawm rau txiav lub voj voog, rov qab mem tes yog siv; qhov tshwm sim rov qab magnetic teb tshem tawm los yog thim rov qab cov kev taw qhia ntawm lub magnetic Circuit Court, ua rau lub armature rov pib dua. Cov yam ntxwv ntawm kev tsav tsheb nkaus xwb los ntawm cov pulses thiab muaj pes tsawg lub zog siv hluav taws xob zoo ua rau nws yog qhov kev xaiv zoo tshaj plaws rau roj teeb- cov xwm txheej muaj zog lossis cov uas muaj lub zog siab heev- txuag cov kev xav tau.
Kev faib tawm los ntawm Txoj Kev Tsav Tsheb thiab Coil Structure
Raws li qhov sib txawv ntawm cov qauv coil thiab tswj txoj kev, sib nqus latching relays feem ntau muab faib ua ob pawg: ib leeg -coil thiab ob-coil hom, txhua tus muaj nws tus kheej tseem ceeb hauv kev tsim hluav taws xob.
Tib -coil magnetic latching relays tsuas muaj ib lub kauj xwb. Txhawm rau hloov cov xeev, cov kev taw qhia (polarity) ntawm cov tam sim no ntws los ntawm lub kauj yuav tsum tau hloov. Feem ntau, cov mem tes zoo tam sim no teev cov relay (sib koom), thiab rov qab mem tes tam sim no rov pib dua (tso tawm). Cov qauv no me dua tab sis muab qhov xav tau ntau dua ntawm kev tsim qauv tsav tsheb, feem ntau xav tau H- choj los tswj cov kev taw qhia tam sim no.
Muab ob npaug rau-coil relays muaj ob lub coils ywj siab: ib txheej kauj thiab rov pib kauj. Los ntawm kev siv cov mem tes voltages ntawm tib lub polarity rau ob lub coils feem, lub hwj chim latching relay tuaj yeem raug kaw thiab qhib. Txoj kev no muaj kev tswj xyuas yooj yim dua, tshem tawm qhov xav tau los xav txog polarity thim rov qab, tab sis nws kuj nce qhov loj ntawm relay thiab tus lej ntawm tus pins. Hauv kev siv cov tswv yim, ntau-ncej relays xws li ob-theem latching relays lossis peb-theem latching relays feem ntau hloov tau yooj yim xaiv lawv cov coil qauv raws li qhov chaw sab hauv kom sib npaug tswj qhov nyuaj thiab qhov xav tau loj.
Hu rau Systems thiab Materials Science
Kev sib txuas lus yog lub "lub plawv" ntawm lub relay, lub luag hauj lwm rau switching circuits rau thiab tawm. Nws qhov kev ua tau zoo ncaj qha txiav txim siab tam sim no - nqa lub peev xwm thiab hluav taws xob lub neej ntawm lub cuab yeej. Hauv kev sib nqus latching relays, kev xaiv ntawm cov ntaub ntawv yog qhov tseem ceeb tshwj xeeb vim yog qhov kev xav tau siab heev rau kev ntseeg siab thiab vuam tsis kam.
Rau siab- daim ntawv thov tam sim no, xws li Bimetal Hu rau 80A / 100A / 120A Sib Nqus Latching Relays, nyiaj- cov ntaub ntawv sib xyaw feem ntau yog siv. Silver muaj qhov zoo tshaj plaws conductivity, thaum sib ntxiv ntawm npib tsib xee, tin oxide, los yog tungsten ho txhim kho cov khoom tiv thaiv arc yaig thiab weld kuj. Hauv particular, tus tsim ntawm Silver Alloy Contacts rau 1/2/3 Theem Latching Meter Relays, los ntawm kev sib xyaw ntawm cov txheej hlau sib txawv, ua kom tsis muaj kev sib cuag ntawm qhov chaw thaum txhim kho cov neeg kho tshuab lub zog thiab kub dissipation ntawm substrate.
Nyob rau hauv lub tshav pob ntawm precision metering, tus tsim ntawm Silver Electronic Contact for Energy Meter Latching Relays tsom ntau rau kev ruaj ntseg ntawm kev sib cuag. Txawm tias me me hloov hauv kev sib cuag kuj tuaj yeem cuam tshuam qhov tseeb ntawm lub zog ntsuas. Yog li ntawd, Cov Kauj Ruam Nyiaj Tiv Tauj no feem ntau tau txais kev kho mob tshwj xeeb, xws li siv Cap Head Silver Contacts qauv, txhawm rau ua kom muaj kev sib cuag thiab thaj chaw sib cuag, kom ntseeg tau tias qhov kev tiv thaiv tiv thaiv tseem nyob ntawm qib milliohm thaum lub sijhawm ua haujlwm ntev -, yog li lav qhov ntsuas qhov tseeb.
Cov xwm txheej ntawm daim ntawv thov thiab kev ua tau zoo
Cov txiaj ntsig zoo ntawm kev sib nqus latching relays tau ua rau lawv muaj txiaj ntsig hauv ntau qhov kev lag luam. Hauv daim phiaj ntse, nws yog ib qho tseem ceeb ntawm cov ntsuas ntse. Raws li kev tsim ua - hauv kev hloov pauv, nws yuav tsum tau ua ntau zaus ua haujlwm hauv chaw taws teeb rau / tawm (xws li kev mus ncig vim kev them nyiaj dhau sijhawm thiab kaw tom qab them nyiaj). Sib nqus latching relays siv Electronic Contacts rau Smart Meter Relay tsis tsuas yog tswj xyuas lub xeev tam sim no thaum lub zog hluav taws xob, tiv thaiv cov ntaub ntawv poob lossis kev hloov pauv hauv lub xeev, tab sis kuj txo qis tus 'meter' tus kheej siv hluav taws xob, ua kom tau raws li qhov yuav tsum tau muaj rau kev tsim kho daim phiaj ntsuab.
Hauv kev lag luam automation thiab lub zog tshiab, Hluav taws xob tiv tauj rau Miniature High -Power Latching Relay tau dav siv hauv photovoltaic inverters, lub zog cia, thiab PLC tswj modules. Cov cheeb tsam no feem ntau muaj qhov kub thiab txias, kev vibrations, lossis kev kub ceev tam sim no. Kev vibration tsis kam thiab cua sov-cov yam ntxwv dawb ntawm cov hlau nplaum latching relays ua haujlwm ruaj khov nyob rau hauv cov xwm txheej hnyav, kom tsis txhob muaj teeb meem kev laus los ntawm cov coil overheating nyob rau hauv ib txwm relays.
Tsis tas li ntawd, nrog kev txhim kho ntawm IoT thev naus laus zis, Miniature Sib Nqus Latching Relays, vim lawv qhov me me thiab tsis tshua muaj hluav taws xob siv, tau maj mam nkag mus rau lub tsev ntse thiab kev ruaj ntseg, muab kev hloov pauv kev tswj hwm rau ntau yam sensors thiab actuators.
Kev tu thiab kev daws teeb meem
Thaum sib nqus latching relays muaj kev ua tau zoo dua, kev saib xyuas yuav tsum tau them rau qhov tshwj xeeb ntawm lub teeb liab tsav thaum siv tswv yim. Tus tsav mem tes dav feem ntau yuav tsum nyob nruab nrab ntawm 10ms thiab 100ms. Pulses uas luv dhau yuav ua rau ua tsis tiav, thaum lub zog txuas ntxiv ntev ntev tuaj yeem ua rau coil overheating lossis demagnetization ntawm cov hlau nplaum ruaj khov. Tsis tas li ntawd, thaum lub sij hawm PCB layout, nws yuav tsum tau ceev kom deb ntawm qhov chaw muaj zog magnetic teb los tiv thaiv sab nraud magnetic teb los ntawm kev cuam tshuam nrog lub relay lub magnetic Circuit Court system. Rau cov khoom muaj tseeb xws li cov ntsiab lus tiv tauj rau DC hluav taws xob latching relays, kev ntsuas kev tiv thaiv tsis tu ncua kuj tseem yog ib feem tseem ceeb ntawm kev tiv thaiv kev saib xyuas kom ntseeg tau ntev -lub sij hawm kev ntseeg siab ntawm kev sib txuas hluav taws xob.
