Lub luag haujlwm ntawm relay yog dab tsi? Nws yog ib yam uas tib neeg xav paub, .Ntawm no peb yuav muab cov ncauj lus kom ntxaws txog kev ua haujlwm ntawm relays. Yog tias koj tsis paub txog cov relays, koj tuaj yeem nias kom paub txogrelay kev paub
Tsis siv neeg tswj kev ua haujlwm
Siv rau / tawm kev tswj ntawm circuitry
Relays tuaj yeem hloov qhov qhib / tawm lub xeev ntawm circuitry raws li qhov sib txawv inputs, xws li voltage thiab tam sim no. Nyob rau hauv ib tug muab tsis siv neeg ntau lawm kab, tom qab lub sensor pom tias tej yam kev mob tau tshwm sim los sai li sai tau lub tig los yog tawm ntawm lub teeb liab coj mus rau ib tug relay kev txiav txim, cov zis uas tshwm sim yuav ua rau ib tug relay txiav txim tswj lub lag luam ntawm lub cev muaj zog los yog valve. hloov qhov cuam tshuam Circuitry rau lossis tawm.
Kev tiv thaiv muaj nuj nqi
Kev tiv thaiv overcurrent thiab undervoltage tiv thaiv
Thaum qhov tam sim no nyob rau hauv Circuit Court yog siab dhau los yog qis dua tus nqi teev, lub relay tuaj yeem txiav tawm hauv Circuit Court los tiv thaiv cov khoom siv hluav taws xob los ntawm kev puas tsuaj vim kev ua haujlwm tsis tshua muaj hluav taws xob.
Kev tiv thaiv overheating
Qee cov khoom siv hluav taws xob, xws li lub cev muaj zog, transformer, thiab lwm yam, yog qhov tsim nyog kom tau txais cua sov. Kub relays yog mounted rau xws li cov cuab yeej rau overheating tiv thaiv. Thaum lub ntsuas kub ntawm lub cuab yeej nce siab tshaj tus nqi teev, qhov kub thiab txias relay ua haujlwm thiab disconnects Circuit Court kom tsis txhob muaj kev puas tsuaj rau lub cuab yeej los ntawm overheating.
Teeb liab amplification muaj nuj nqi
Tam sim no amplification
Txij li thaum cov kev sib cuag ntawm cov relays tuaj yeem txhawb nqa loj tam sim no, nws muaj peev xwm hloov me me tam sim no input Pib ntsais koj teeb rau cov zis tam sim no loj thiab yog li ua tiav cov haujlwm ntawm tam sim no amplification.
Voltage amplification
Ib yam li ntawd, relays kuj tuaj yeem ua tiav qhov kev ua haujlwm ntawm voltage amplification. Thaum lub teeb liab input voltage tsawg, lub relay coil thiab cov neeg tuaj yeem hloov cov input voltage mus rau qhov siab tso zis voltage kom tau raws li qhov voltage ntawm cov khoom sib txawv.
Kev rho tawm haujlwm
Kev cais hluav taws xob
Electromagnetic induction tsav lub relay coil thiab kev sib cuag. Yog li, kev sib cais hluav taws xob tau ua tiav ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob. Qhov kev sib cais no yuav, mus rau qib zoo, zam cov teeb meem txaus ntshai ntawm cov hluav taws xob siab thiab siab tam sim no hauv cov khoom siv hluav taws xob los ntawm kev ua rau muaj kev puas tsuaj hauv cov khoom siv thiab cov neeg ua haujlwm hauv cov khoom siv hluav taws xob.
Teeb liab cais
Dhau li ntawm kev sib cais hluav taws xob, cov relays kuj tuaj yeem ua tiav cov haujlwm ntawm cov teeb liab cais tawm. Lub relay tuaj yeem hloov cov teeb liab tawm tswv yim rau hauv lub teeb liab ua haujlwm ntawm kev sib cuag thiab ua tiav cov teeb liab sib cais kis tau tus mob los ntawm kev tswj lub on / off ntawm cov zis Circuit Court nrog qhib thiab kaw nyob rau hauv cov ntaub ntawv ntawm qhov yuav tsum tau hais tias lub input teeb liab thiab tso zis teeb liab raug cais tawm ntawm txhua. lwm yam.
Rau qee qhov kev tswj hwm automation, kev sib cais ntawm cov teeb liab tuaj yeem tiv thaiv kev cuam tshuam cov teeb liab sib txawv thiab sib tham; nws txhim khu kev ruaj ntseg thiab kev cia siab ntawm qhov system.
Txheej txheem cej luam
Muaj ntau ntau yam kev faib tawm ntawm cov relay, uas tom qab ntawd muab peb ntau yam ntxwv thiab kev ua haujlwm. Lawv kuj tseem siv tau ntau yam hauv lub neej niaj hnub, ib yam li lub tshuab hluav taws xob pib ntawm cov khoom siv hauv tsev lossis tsheb nyob ib puag ncig peb. Xaiv qhov zoo ntawm relay tuaj yeem txhim kho nws txoj haujlwm zoo dua. Kev paub ntxiv?
