Main muaj nuj nqi:
Relayyog ib qho kev hloov pauv tsis siv neeg nrog kev sib cais ua haujlwm, dav siv hauv kev tswj chaw taws teeb, telemetry, kev sib txuas lus, kev tswj tsis siv neeg, mechatronics thiab cov khoom siv hluav taws xob hluav taws xob, yog ib qho tseem ceeb tshaj plaws ntawm kev tswj cov khoom.
Relay feem ntau muaj ib qho induction mechanism (input part) uas tuaj yeem cuam tshuam qee qhov kev hloov pauv (xws li tam sim no, voltage, hwj chim, impedance, zaus, kub, siab, ceev, lub teeb, thiab lwm yam)."on" thiab" tawm" kev tswj ntawm cov tswj Circuit Court; nruab nrab ntawm qhov kev tawm tswv yim thiab cov zis ib feem ntawm relay, muaj ib qho nruab nrab mechanism (tsav ib feem) rau kev sib txuas ntawm kev sib cais ntawm cov tswv yim, kev ua haujlwm thiab kev tsav tsheb ntawm cov khoom tso tawm.
Raws li lub hauv paus tswj, relay muaj cov haujlwm hauv qab no:
1) Expand qhov kev tswj ntau yam:Piv txwv li, thaum lub teeb liab tswj ntawm ntau qhov sib cuagrelayncav cuag ib qho nqi, nws tuaj yeem hloov kev sib txuas, qhib thiab kaw ntau lub voj voog tib lub sijhawm raws li ntau hom kev sib cuag ntawm pawg.
2) Amplification:Piv txwv li, rhiab heev relay, intermediate relay, thiab lwm yam, nrog ib tug me me npaum li cas ntawm kev tswj, muaj peev xwm tswj tau ib tug loj hwj chim Circuit Court.
3) Integrated signal:Piv txwv li, thaum muaj ntau yam kev tswj cov teeb liab nkag mus rau hauv multi-winding relay nyob rau hauv ib daim ntawv teev, lub predetermined tswj nyhuv yuav ua tau tiav los ntawm kev sib piv thiab synthesis.
4) Tsis siv neeg, chaw taws teeb tswj, saib xyuas:Piv txwv li, lub relay ntawm lub tshuab tsis siv neeg ua ke nrog rau lwm yam khoom siv hluav taws xob tuaj yeem tsim ib qho kev tswj xyuas Circuit Court, kom paub txog kev ua haujlwm tsis siv neeg.
Lus Cim:
Rated ua haujlwm voltage:hais txog qhov voltage xav tau los ntawm lub kauj thaum lubrelayua hauj lwm ib txwm, uas yog, tswj voltage ntawm kev tswj Circuit Court.Nyob ntawm hom relay, nws yuav ua tau ac voltage los yog DC voltage.
Dc kuj:Hais txog DC tsis kam ntawm lub kauj hauv relay, uas tuaj yeem ntsuas los ntawm multimeter.
Pull-in tam sim no:hais txog qhov tsawg kawg nkaus tam sim no uas tus relay tuaj yeem tsim rub-hauv kev ua haujlwm. Hauv kev siv ib txwm, qhov muab tam sim no yuav tsum yog me ntsis siab dua li rub-hauv tam sim no rau lub relay ua haujlwm ruaj khov.Rau qhov ua haujlwm voltage ntxiv los ntawm kauj, feem ntau ua. tsis pub tshaj 1.5 npaug ntawm qhov ntsuas ua haujlwm voltage, txwv tsis pub nws yuav ua rau lub zog loj dua thiab hlawv lub kauj.
Tso tawm tam sim no:yog hais txog qhov siab tshaj plaws tam sim no ntawm cov relay los tsim tawm qhov kev txiav txim.Thaum qhov tam sim no nyob rau hauv lub latch lub xeev ntawm lub relay txo mus rau ib qho twg, lub relay yuav rov qab mus rau lub unenergized tso lub xeev.Qhov tam sim no ntawm qhov tam sim no ntau me dua qhov nqus. tam sim no.
Hu rau switching voltage thiab tam sim no:hais txog qhov voltage thiab tam sim no uas lub relay tso cai rau load.Nws txiav txim siab qhov voltage thiab tam sim no uas tus relay tswj tau. Tsis txhob siv ntau tshaj li tus nqi no, txwv tsis pub nws yooj yim rau kev puas tsuaj rau kev sib cuag ntawm lubrelay.
