Feem ntau, mechanical relays yog siv nyob rau hauv ntau yam khoom siv hluav taws xob thaum muaj kev tswj xyuas tam sim no. Cov relays hloov qhov ntws ntawm tam sim no los ntawm kev qhib thiab kaw lub cev tiv tauj. Txawm hais tias lawv qhov zoo ntawm kev ntseeg siab thiab tus nqi qis, tseem muaj qee qhov tsis zoo uas tsis tuaj yeem tsis quav ntsej. Hauv qab no yog tsib qhov tsis zoo uas cov tshuab hluav taws xob hloov hluav taws xob muaj, thiab ntxiv rau hauv tsab xov xwm no, qee qhov tseem ceeb uas tuaj yeem ua si hauv kev xaiv thiab siv cov cuab yeej tau tham.
Nkag siab txog cov qauv ntawm mechanical relays
Hluav taws xob: Qhov no yog qhov tseem ceeb tshaj plaws ntawm relays. Thaum twg tam sim no dhau los ntawm electromagnetic coils, nws tsim ib magnetic teb. Thaum lub relay coil yog energized, ib tug magnetic teb yog tsim uas attracts cov tub ntxhais hlau.
Hlau tub ntxhais: Nws feem ntau yog ua los ntawm cov khoom sib nqus mos. Nws lub hom phiaj yog tshem tawm vim electromagnetic attraction. Cov tub ntxhais hlau txav los ntawm kev tswj qhov qhib thiab kaw ntawm qhov hloov.
Hu rau: Relay hu yog cov khoom uas txuas los yog txiav tawm circuits. Qhov ib txwm qhib, ib txwm kaw, thiab kev sib txuas sib txuas tau suav nrog hauv kev sib cuag. Thaum lub electromagnet nyiam cov tub ntxhais hlau, cov kev sib cuag hloov mus rau kev sib txuas los yog txiav tawm hauv Circuit Court.
Caij nplooj ntoos hlav:Nws ua kom rov qab cov tub ntxhais hlau nyob rau hauv qhov tsis muaj zog rau nws ib txwm qhib lub xeev nyob rau hauv lub electromagnet, yog li kho cov relay rov qab mus rau nws thawj txoj hauj lwm. Lub zog rov qab los ntawm qhov no yuav txiav tawm lossis txuas cov neeg sib cuag.
Vim muaj qee qhov kev poob thaum siv mus sij hawm ntev, kev pab cuam lub neej ntawm txhua yam khoom siv kuj raug txwv. Tom ntej no, peb yuav tshawb xyuas qhov tsis txaus ntawm cov tshuab hluav taws xob relays los ntawm tsib yam thiab nthuav tawm cov kev ntsuas cuam tshuam.
Lub neej teeb meem tshwm sim los ntawm kev siv tshuab thiab tsim kua muag
Lub hauv paus ntsiab lus ua haujlwm tseem ceeb ntawm cov khoom siv hluav taws xob yog tswj xyuas tam sim no los ntawm kev sib cuag ntawm lub cev thiab kev sib txuas ntawm cov hlau sib txuas. Txawm li cas los xij, raws li lub sijhawm siv tau nce, cov neeg sib cuag yuav hnav vim rov qab sib cuag lub cev. Kev hnav zoo li no tuaj yeem ua rau kev sib cuag tsis zoo thiab nce impedance ntawm relay hloov, thiab txawm tias thaum kawg ua rau relay tsis ua haujlwm.

Yog hais tias daim ntawv thov scenario yuav tsum tau hloov tsis tu ncua, solid-state relays los yog ntau dua cov neeg kho tshuab relay qauv yuav raug txiav txim siab. Xwb, koj tuaj yeem xaiv tus xa khoom zoo tshaj plaws,QIANJI, uas muab lub neej ntev thiab zoomechanical relaysib yam li tshiabsolid-state relays
Slow Teb Ceev
Cov keyboards yog qhib thiab kaw los ntawm mechanical motion. Qhov no ua rau cov lus teb ceev ntawm relay kuj qeeb. Rau cov ntawv thov uas xav tau cov lus teb ceev, xws li automation tswj systems thiab high-speed circuits, lub sij hawm teb ntawm cov neeg kho tshuab relay yuav tsis txaus.

Thaum muaj qhov yuav tsum tau siv cov kev tswj xyuas ceev ceev, cov khoom siv hluav taws xob hauv xeev lossis lwm yam khoom siv hluav taws xob hloov pauv yuav tsum raug xaiv, teb sai dua.
Tsim hluav taws xob arc
Thaum cov kev sib cuag ntawm cov neeg kho tshuab relay qhib los yog kaw, tam sim no yuav ua rau arcing ntawm cov neeg sib cuag. Hom arc no tuaj yeem ua rau lub ntsej muag sib cuag, ntxiv rau kev laus ntawm cov relay, thiab tseem ua rau muaj kev pheej hmoo ntawm hluav taws kub lossis hluav taws xob.
cawv
Kev puas tsuaj ntawm arc: Ib qho arc tuaj yeem ua rau lub melting los yog paug ntawm relay hu, uas ua rau txo qis hauv kev ua haujlwm ntawm relay.
Kev nyab xeeb kev nyab xeeb: hluav taws xob arcs kuj tuaj yeem ua rau hluav taws kub lossis hluav taws xob tsis ua haujlwm, cuam tshuam rau kev nyab xeeb ntawm lub cev.
Teb zoo
Thaum tsim cov circuits, cov tswv yim arc suppression yuav raug txiav txim siab, xws li ntxiv cov capacitors lossis resistors nyob ib sab ntawm cov neeg, lossis xaiv cov relays nrog kev ua haujlwm zoo dua arc dissipation.
Mechanical suab nrov
Mechanical relays ua suab nrov thaum lub sijhawm ua haujlwm, tshwj xeeb tshaj yog thaum hloov ntawm qhov siab. Hom suab nrov no yuav muaj kev cuam tshuam rau kev ruaj ntseg thiab cov neeg siv kev paub ntawm lub cuab yeej, tshwj xeeb tshaj yog nyob rau hauv cov suab nrov rhiab heev xws li cov cuab yeej siv kho mob lossis cov tshuab ua haujlwm siab.
cawv
Lub suab nrov cuam tshuam: Lub suab "nias" ntawm relays thaum lub sij hawm hloov yuav cuam tshuam rau kev ua haujlwm ntawm cov khoom siv lossis kev nplij siab ntawm ib puag ncig.
Kev cuam tshuam rau cov neeg siv kev paub: Rau qee cov ntawv thov uas xav tau kev ntsiag to, cov neeg kho tshuab relays yuav tsis yog qhov kev xaiv zoo tshaj plaws.
Teb zoo
Rau cov ntawv thov uas xav tau lub suab qis, cov suab ntsiag to lossis cov khoom siv hluav taws xob tuaj yeem raug txiav txim siab, vim tias cov khoom siv no tsis muaj qhov txav ntawm lub cev thiab yog li tsis muaj suab nrov.
Yooj yim los cuam tshuam los ntawm ib puag ncig yam
Kev ua haujlwm ntawm cov tshuab hluav taws xob relay tuaj yeem cuam tshuam los ntawm ib puag ncig yam xws li kub, av noo, thiab plua plav. Qhov kub thiab txias ib puag ncig yuav ua rau corrosion los yog khov ntawm kev sib cuag relay, yog li cuam tshuam rau lawv txoj kev ntseeg siab thiab ruaj khov.
Kev npam
Kub variation: Kub kub tuaj yeem yaj los yog ua rau cov kev sib cuag relay puas thiab tsis kub yuav ua rau cov relay ua haujlwm tsis zoo.
Humidity: Vim yog noo noo, cov ntsiab lus tiv tauj tuaj yeem corrode thiab poob hauv Circuit Court.
Plua plav: Txij li cov plua plav thiab lwm yam impurities tuaj yeem nkag mus rau sab hauv ntawm lub relay thiab ua haujlwm tsis zoo, ua rau luv luv lossis lwm yam kev txhaum.
Tswv yim
Cov qauv kev tiv thaiv yuav tsum raug xaiv uas, rau cov neeg kho tshuab relays tsim nyog rau ntau qhov chaw ntawm ib puag ncig lossis tso lub relay rau hauv lub kaw lus kaw kom tsis txhob cuam tshuam los ntawm ib puag ncig.
Cov ntsiab lus
Txawm hais tias cov khoom siv hluav taws xob relay tau siv dav hauv ntau qhov chaw vim lawv qhov yooj yim, kev ntseeg tau, thiab tus nqi qis, lawv qhov tsis zoo kuj yuav tsum tau txais kev saib xyuas txaus. Los ntawm txhua yam hnav thiab arcing teeb meem rau cov lus teb ceev thiab lub suab nrov, cov teeb meem no yuav cuam tshuam rau lub sijhawm ntev thiab kev ua haujlwm ntawm relays.
Thaum xaiv siv cov khoom siv hluav taws xob, xyuas kom tseeb tias lawv haum rau koj daim ntawv thov xav tau thiab xav txog lwm txoj kev daws teeb meem, xws li cov khoom siv hluav taws xob, uas yuav tsim nyog dua. Tab sis tus nqi ntawm solid-state relays yuav kim dua li cov neeg kho tshuab relays. Yog tias koj xav tau cov kev xav tau relay, koj tuaj yeem ua tautiv tauj peb. Peb yog ib tus kws tshaj lij relay tus neeg muag khoom uas tuaj yeem kho koj cov kev xav tau rau cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob, thiab muab cov nqi pheej yig
