Thaum lub relay siv los tswj cov cuab yeej siv hluav taws xob siab, nws tuaj yeem hloov nrog lub teeb liab qis. Lub relay yog qhov tseem ceeb ntawm cov cuab yeej nruab nrab uas ua rau peb tig lub voj voog rau lossis tawm ntawm qhov deb. General-purpose relay tsim ib qho tseem ceeb ntawm txhua qhov system uas xav tau kev hloov pauv ntawm ntau lub voj voog lossis tswj cov khoom siv hluav taws xob siab.
Lub hom phiaj dav dav relay yog dab tsi?
Ib qho kev hloov pauv dav dav yog qhov hloov hluav taws xob uas qhib lossis kaw lub voj voog los ntawm cov teeb liab hluav taws xob thiab feem ntau yog siv rau automation thiab tswj lub hom phiaj. Nws yog hu ua "general relay" vim tias nws muaj ntau yam kev siv tau thiab tuaj yeem siv rau hauv ntau qhov kev lag luam xws li khoom siv hauv tsev, kev siv tshuab thiab tshuab tsheb. Cov relays no tuaj yeem tswj tau ntau yam tam sim no thiab voltage loads, ua rau lawv tswj Circuit Court hauv ntau qhov chaw sib txawv.
General relay ua haujlwm li cas?
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm kev sib txuas lus dav dav yog qhov yooj yim, tab sis nws ua tau zoo heev. Lub relay tswj qhov qhib thiab kaw ntawm cov keyboards (los yog ntau lub keyboards) los ntawm electromagnets. Thaum tam sim no dhau los ntawm lub kauj ntawm lub relay, qhov hloov ntawm lub relay hloov.
Lub hauv paus ntsiab lus ua haujlwm ntawm relay yog siv electromagnet los qhib lossis kaw qhov hloov. Thaum lub qhov hluav taws xob kaw, qhov hluav taws xob txuas nrog thiab tam sim no tuaj yeem ntws. Thaum lub qhov hluav taws xob qhib, qhov hluav taws xob raug txiav thiab qhov tam sim no tsis tuaj yeem ntws.
Cov hom phiaj dav dav tuaj yeem siv los tswj ntau yam khoom siv, suav nrog lub cev muaj zog, lub teeb, thiab cov twj tso kua mis. Lawv feem ntau yog siv rau hauv cov ntawv thov uas yuav tsum tau hloov me me tam sim no, xws li cov khoom siv hauv tsev, cov khoom siv hluav taws xob hauv tsheb, thiab cov khoom siv hauv chaw ua haujlwm.
Cheebtsam ntawm general relay
General relay muaj ob peb yam tseem ceeb los xyuas kom meej tias nws txoj haujlwm zoo:
Coil: thaum tam sim no dhau los ntawm lub kauj, ib qho chaw magnetic generated.
Tiv tauj: cov khoom siv hluav taws xob no yuav qhib thiab kaw thaum lub sijhawm tsim nyog los tswj cov dej ntws tam sim no. Hom kev sib cuag muaj xws li ib txwm qhib (tsis muaj) thiab ib txwm kaw (NC) kev sib cuag.
Cov tub ntxhais kis tau tus mob: ib qho chaw txav tau txav tau nyob rau hauv qhov kev txiav txim ntawm qhov chaw sib nqus, yog li hloov lub xeev ntawm kev sib cuag.
Caij nplooj ntoos hlav: xyuas kom meej tias thaum qhov tam sim no raug txiav tawm, cov tub ntxhais tsav hlau tuaj yeem rov qab mus rau qhov qub los pab cov relay pib dua.
Tsev / ncej: tiv thaiv relay sab hauv cov khoom los ntawm cov plua plav thiab kev puas tsuaj.
Hom hom phiaj dav dav relays
Electromagnetic relay: feem ntau hom relay, uas tsav cov tub ntxhais tsav los ntawm cov hlau nplaum tsim los ntawm lub kauj thiab paub txog kev hloov pauv. Zoo tagnrho rau kev siv lub hom phiaj dav dav.
Solid state relay: tsis zoo li electromagnetic relay, solid state relay (SSR) tsis muaj qhov txav txav, tab sis siv cov khoom siv hluav taws xob los ua haujlwm hloov. Cov khoom hauv lub xeev relays muab cov lus teb sai dua, qis suab nrov thiab muaj zog dua.
Thermal relay: qhov relay no yog siv los tiv thaiv overload. Cov ntawv bimetal khoov tom qab cua sov, ua rau qhov kev sib cuag qhib thiab tiv thaiv Circuit Court los ntawm overcurrent. Nws yog tsuas yog siv rau kev tiv thaiv lub cev muaj zog.
Kev siv dav dav ntawm relay
Cov khoom siv hauv tsev: piv txwv li, hauv tub yees, tshuab ntxhua khaub ncaws thiab cua txias, relays yog siv los tswj cov motors, cua sov cov ntsiab lus thiab teeb pom kev zoo.
Kev lag luam tshuab: Relay plays lub luag haujlwm tseem ceeb hauv kev tswj cov khoom siv xws li conveyor siv, elevators, thiab robots. Lawv muaj peev xwm automate mechanical kev khiav hauj lwm thiab txo cov kev khiav hauj lwm phau ntawv.
Automotive Kev Lag Luam: siv hauv tsheb los tswj lub teeb, thiab cua txias. Cov relays hloov cov khoom siv hluav taws xob siab thiab, yog li ntawd, tiv thaiv hluav taws xob hluav taws xob.
