Relay yog ib yam khoom siv hluav taws xob tswj, uas tuaj yeem paub txog kev ua haujlwm ntawm kev faib hluav taws xob thiab kaw, sijhawm ncua sijhawm, hloov pauv, thiab lwm yam. Nws yog dav siv nyob rau hauv ntau yam automation tswj systems. Thaum siv cov relays, peb yuav tsum tau them sai sai rau qhov ntsuas hluav taws xob ntawm lub relay kom ntseeg tau tias nws ua haujlwm zoo thiab siv tau zoo.
I. Relay rated voltage yog dab tsi?
Qhov ntsuas hluav taws xob relay yog hais txog qhov siab tshaj plaws kev khiav hauj lwm qhov hluav taws xob uas lub relay tuaj yeem tiv taus nyob rau hauv ib txwm ua haujlwm. Thaum lub relay ua haujlwm, yog tias qhov kev siv hluav taws xob ua haujlwm dhau qhov ntsuas tus nqi, kev puas tsuaj yuav tshwm sim rau lub relay. Yog li ntawd, thaum xaiv thiab siv ib tug relay, nws rated voltage yuav tsum tau coj mus rau hauv tus account.
II. Yuav ua li cas txiav txim siab qhov ntsuas voltage ntawm relay?
1. Xaiv raws li daim ntawv thov
Cov sijhawm sib txawv yuav tsum tau siv ntau hom relays, qhov ntsuas kev khiav hauj lwm voltage kuj txawv. Feem ntau hais lus, cov teeb liab me me siv hauv cov ntawv thov hluav taws xob tsawg muaj qhov ntsuas kev ua haujlwm ntawm 5V-24V; thaum lub zog siab contactors siv nyob rau hauv cov ntaub ntawv siv hluav taws xob siab yuav tsum muaj kev siab ntev dua, thiab lawv cov kev ntsuas kev ua haujlwm tuaj yeem ncav cuag 220V-380V.
2. Kev xaiv raws li hom kev thauj khoom
Load hom kuj yog ib qho tseem ceeb hauv kev txiav txim siab yam, hom thiab qauv ntawm relay xaiv. Yog hais tias lub load yog inductive nyob rau hauv cov xwm, xws li motors, lub teeb qhov muag teev, thiab lwm yam., ces nyob rau hauv lub relay disconnect yuav tsim ib tug rov qab electromotive quab yuam, ces koj yuav tsum xaiv ib tug relay nrog ib tug siab kam rau ua; Yog hais tias lub load yog purely resistive nyob rau hauv cov xwm, ces koj muaj peev xwm xaiv ib tug qis rated khiav hauj lwm voltage relay.
III. Kev sib raug zoo ntawm qhov ntsuas hluav taws xob thiab kev pab cuam lub neej ntawm relays
Muaj kev sib raug zoo ntawm qhov ntsuas kev khiav hauj lwm voltage thiab lub neej kev pab cuam ntawm lub relay. Raws li kev siv ib txwm muaj, yog tias qhov ntsuas kev ua haujlwm ntau dhau, kev puas tsuaj yuav tshwm sim rau lub relay, yog li ua rau nws lub neej ua haujlwm luv. Tsis tas li ntawd, nyob rau hauv kev siv mus sij hawm ntev, vim yog qhov cuam tshuam ntawm qhov kub thiab txias, av noo thiab lwm yam, nws kuj tseem tuaj yeem ua rau muaj qhov tshwm sim ntawm kev laus ntawm relay, uas tseem yuav tsum tau hloov lossis kho.
VI, Kuv tuaj yeem txhim kho qhov hluav taws xob tiv thaiv ntawm relay li cas?
Hauv kev xyaum, ntau qhov kev ntsuas tuaj yeem ua tau txhawm rau txhim kho qhov voltage tsis kam ntawm relays.
1. Xaiv tus qauv tsim thiab hom
Raws li qhov sib txawv daim ntawv thov scenarios yuav tsum xaiv hom thiab hom relay. Feem ntau hais lus, nyob rau hauv tib lub zog, kev ua tau zoo ntawm cov khoom lag luam nrog cov khoom lag luam zoo thiab tus nqi siab dua yog qhov zoo dua, QIANJi Relay yog cov chaw tsim khoom lag luam sib txuas nrog ntau ntau hom relays xws li fais fab relays, pcb relays, khoom hauv lub xeev relays thiab lwm yam. ntawm. Thiab qhov zoo yog zoo heev thiab tus nqi kom zoo dua yog loj. Tag nrho automated ntau lawm cog. Thiab los ntawm kev ua tau zoo thiab kev ua tau zoo, tshwj xeeb tshaj yog nyob rau hauv kev lag luam.
2. Ua kom cov rwb thaiv tsev nyob deb
Nyob rau hauv kev tsim ntawm relays, qhov kev ncua deb ntawm rwb thaiv tsev tuaj yeem nce ntxiv, yog li kev txhim kho lawv qhov voltage kuj. Piv txwv li, cov khoom uas muaj qhov sib cais nyob rau hauv qab ntawm lub relay tuaj yeem siv tau.
3. Txhim kho cua sov dissipation
Hauv kev siv hluav taws xob siab, nws yog ib qho tsim nyog los xaiv cov relays nrog kev ua haujlwm zoo ntawm cov cua sov kom ntseeg tau tias lawv cov haujlwm ib txwm muaj. Tsis tas li ntawd, cov cua kub dissipation tuaj yeem txhim kho los ntawm kev ntxiv cov dab dej kub thiab kiv cua.
Cov ntsiab lus.
Relay ntsuas hluav taws xob yog ib qho tseem ceeb cuam tshuam rau nws txoj haujlwm ib txwm muaj thiab kev pabcuam lub neej. Yog li ntawd, thaum xaiv thiab siv cov relays, nws yog ib qho tseem ceeb uas yuav tsum xaiv tus qauv thiab hom raws li qhov xav tau tiag tiag, thiab xyuam xim rau qhov kub thiab txias, av noo thiab lwm yam ntawm nws cov cawv. Tsuas yog nyob rau hauv txoj kev no peb tuaj yeem ua kom muaj kev ruaj ntseg thiab kev ntseeg siab ntawm cov relay. Pom zoo relay chaw tsim tshuaj paus hom - QIANJI relay, nyem ntxiv kom kawm.
