Lub luag haujlwm, hom, thiab qhov sib txawv ntawm AC thiab DC Relays hauv Kev Pabcuam Relays

Nrog rau kev txhim kho txuas ntxiv ntawm kev lag luam automation thiab hluav taws xob tswj tshuab, relays, raws li qhov tseem ceeb thiab tseem ceeb ntawm kev tswj cov khoom, tab tom ntsib kev nyuaj thiab kev ua haujlwm. Tshwj xeeb tshaj yog nyob rau hauv PLC tswj systems, kev xaiv kom zoo ntawm pab relays, AC relays, thiab DC relays ncaj qha cuam tshuam rau lub system stability thiab kev nyab xeeb. Kab lus no yuav ua tib zoo tshuaj xyuas cov haujlwm thiab kev faib tawm ntawm cov koom haum pabcuam, nrog rau cov qauv thiab kev siv qhov sib txawv ntawm AC thiab DC relays, los ntawm kev xav txog engineering.

 

 

Cov pab txhawb nqa tsis yog ib txwm siv lub cev electromagnetic relays, tab sis theej logic relays siv hauv software hauv PLC system. Lawv tsis tuaj yeem tau txais cov lus qhia tawm sab nraud lossis ncaj qha tsav tsheb thauj khoom. Lawv lub luag haujlwm tseem ceeb yog ua raws li cov xwm txheej sab hauv tus chij thiab cov kev sib txuas lus sib txuas lus rau cov teeb liab kis tau tus mob, kev txiav txim siab, thiab kev ua haujlwm zoo. Functionally, auxiliary relays yog sib npaug rau "intermediate relays" nyob rau hauv ib txwm relay tswj systems, tab sis lawv cov kev sib cuag muaj nyob rau hauv qhov kev pab cuam logic.

 

Thaum lub sijhawm ua haujlwm PLC, ib txwm qhib thiab ib txwm kaw kev sib cuag ntawm cov pab cuam relays tuaj yeem siv tsis pub dhau lub sijhawm los tsim cov kev sib raug zoo ntawm kev sib raug zoo, yog li txhim kho cov kev pab cuam nyeem ntawv, kev ruaj ntseg, thiab scalability. Cov coils ntawm cov relays no yog tsav los ntawm PLC cov khoom muag hauv sab hauv thiab tsis ncaj qha ntsig txog cov qauv hluav taws xob sab nraud. Lawv koom rau qib kev sib txawv dua li cov khoom sib nqus hauv lub cev relays, xws li Pure Iron Core rau AC Relay.

 

 

Raws li qhov xav tau tiag tiag ntawm kev tswj hwm kev lag luam, auxiliary relays feem ntau tuaj yeem muab faib ua peb pawg tseem ceeb: dav dav -lub hom phiaj pabcuam relays, roj teeb thaub qab (latching) auxiliary relays, thiab tshwj xeeb auxiliary relays. Ntau hom ua haujlwm sib txawv hauv lub hwj chim-tawm lub cim xeeb, lub xeev tuav tswj, thiab kev qhia ua haujlwm.

 

General - lub hom phiaj pab relays tsis muaj lub hwj chim - tawm kev tuav pov hwm. Thaum lub sijhawm ua haujlwm PLC, thaum lub kaw lus poob lub zog, nws lub xeev tau rov pib dua; Thaum lub hwj chim kho dua tshiab, lub xeev tsuas yog txiav txim los ntawm cov khoom siv tam sim no. Cov auxiliary relays no feem ntau yog siv rau kev tswj xyuas cov logic thiab tsis cuam tshuam rau lub xeev tseem ceeb.

 

Roj teeb thaub qab lossis latching auxiliary relays yog siv rau hauv cov tshuab uas xav tau lub cim xeeb ntawm lub xeev tam sim ntawd thaum lub hwj chim -tawm. Cov relays no, siv los ntawm lithium roj teeb lossis tsis yog - lub cim xeeb tsis zoo, tuaj yeem rov qab lawv lub xeev ua ntej lub zog tsis ua haujlwm nyob rau hauv thawj lub voj voog scan tom qab fais fab tuag -on, feem ntau pom nyob rau hauv cov ntawv thov uas xav tau kev txuas ntxiv hauv lub xeev lossis kev nyab xeeb pib dua.

 

Kev pabcuam tshwjxeeb feem ntau yog siv los qhia txog PLC txoj haujlwm ua haujlwm, moos pulses, cov chij kab ke, lossis kev tswj xyuas raws li kev xav tau. Cov relays ua raws li "system-theem teeb liab qhov chaw" nyob rau hauv complex tswj systems, zoo ib yam li cov qauv tsim ntawm ib tug hardware system siv ib tug AC relay core thiab tooj liab nplhaib los siv tshwj xeeb functions.

 

 

Hauv kev siv engineering, qhov tseem ceeb ntawm qhov sib txawv ntawm AC thiab DC relays nyob rau hauv lawv cov coil fais fab mov hom. Relays uas ua hauj lwm ntawm alternating tam sim no yog AC relays, thaum cov uas ua hauj lwm ntawm ncaj qha tam sim no yog DC relays. Nws yog ib qho tseem ceeb uas yuav tsum tau hais tias qhov kev faib tawm no tsuas yog siv rau lub kauj voj voog; sab tiv tauj tuaj yeem tswj tau ob qho tib si AC thiab DC loads.

 

Los ntawm kev tsim qauv tsim, AC thiab DC relays sib txawv hauv lawv cov sib nqus circuits thiab cov txheej txheem cua sov. Cov kev sib txawv no cuam tshuam ncaj qha rau lawv cov kev ua haujlwm thiab kev ntseeg tau.

 

 

AC relays feem ntau siv cov hlau tuab dua thiab tsawg dua coil tig. Lawv cov qauv tseem ceeb suav nrog luv luv - lub nplhaib hluav taws xob (lub nplhaib tooj liab) kom txo qis kev co thiab suab nrov los ntawm kev hloov pauv hauv AC magnetic flux. Cov cores ntawm cov relays no feem ntau yog E- hom lossis laminated qauv, yuav tsum muaj kev ua haujlwm siab thiab feem ntau cuam tshuam nrog cov txheej txheem tsim khoom xws li DT4C AC Relay Iron core CNC tshuab dhos ua.

 

Hauv qhov sib piv, DC relays siv cov xaim nyias nyias thiab muaj ntau qhov lem. Cov tub ntxhais feem ntau yog cylindrical thiab tsis xav tau lub nplhaib luv luv -circuit. Txij li thaum tshav kub tsim nyob rau hauv DC systems yog mas concentrated nyob rau hauv lub kauj nws tus kheej, lub kauj yog feem ntau nyob rau hauv ncaj qha kev sib cuag nrog cov tub ntxhais, cia siab rau cov tub ntxhais rau tshav kub dissipation; Yog li ntawd, DC relays feem ntau tsim nrog "siab thiab nyias" profile.

 

Hauv AC electromagnetic systems, cov tub ntxhais yog lub ntsiab cua sov- tsim cov khoom, yog li feem ntau yog ib qho kev sib cais ntawm cov kauj thiab cov tub ntxhais. Nyob rau hauv DC systems, lub kauj yog lub ntsiab cua sov qhov chaw, thiab cov qauv tsim qhia txog lub tshav kub conduction txoj kev.

 

 

Nyob rau hauv kev siv tswv yim, lub relay coil thiab kev sib cuag Circuit Court yog hluav taws xob cais los ntawm ib leeg. Yog li ntawd, relays nrog AC coils tuaj yeem muaj lawv cov kev sib cuag txuas nrog DC circuits; Zoo sib xws, relays nrog DC coils tuaj yeem tswj AC circuits. Qhov kev teeb tsa no muaj peev xwm ua tau, tab sis nws tuaj yeem qhia qhov cuam tshuam los yog kev sim cuam tshuam hauv cov txheej txheem nyuaj, yuav tsum tau saib xyuas thaum tsim thiab kho.

 

 

Los ntawm kev pom daim ntawv thov, AC relays feem ntau siv hauv kev tswj hwm kev lag luam vim lawv cov khoom siv hluav taws xob yooj yim thiab siv dav. DC relays feem ntau yog siv hauv ob qhov xwm txheej hauv qab no:

 

Ua ntej, nyob rau hauv kev tiv thaiv thiab kev sib tshuam systems, thaum lub AC fais fab mov tsis ua hauj lwm, kev tiv thaiv logic tseem yuav tsum tau tshwm sim los ntawm DC system; thib ob, nyob rau hauv siab - daim ntawv thov kev tswj fais fab uas xav tau lub zog hluav taws xob siab, DC relays tuaj yeem muab lub zog rub- nyob rau hauv kev quab yuam nyob rau hauv tib lub voltage. Hauv tsheb, hluav taws xob tsheb thauj mus los, thiab DC fais fab mov, DC relays yuav luag dhau los ua cov khoom siv.

 

 

Txawm hais tias nws yog daim ntawv thov kev sib txuas lus los yog cov qauv sib txawv ntawm AC thiab DC relays, lawv cov ntsiab lus ua haujlwm ruaj khov thiab tswj tau ntawm lub kaw lus. Nyob rau hauv cov khoom relay, lub kauj, electromagnetic system, thiab cov qauv tseem ceeb yog ib txwm lub hauv paus tseem ceeb txiav txim siab ua haujlwm. Qhov kev thov nce ntxiv rau siab -kev sib raug zoo, siab-permeability hlau cores hauv AC relay daim ntawv thov tau tsav qhov txuas ntxiv ntawm cov qauv siv xws li AC Relay Core thiab Copper Ring, thiabGrooved Core rau AC Relaynyob rau hauv industrial teb.

 

 

Raws li kev tshawb fawb ntev - mus rau hauv kev ua hauj lwm mechanism thiab daim ntawv thov ib puag ncig ntawm AC relays, peb tshwj xeeb hauv kev tsim thiab kho cov AC relay cores -cov khoom muaj feem xyuam, nrog rau kev lag luam- qib relay cores, tooj liab nplhaib sib xyaw cov qauv, thiab precision- cov tub ntxhais sib dhos. Peb cov khoom siv dav siv hauv kev tswj hwm kev lag luam, cov cuab yeej siv hluav taws xob, thiab cov tshuab hluav taws xob, thiab peb tuaj yeem muab cov khoom siv thiab cov txheej txheem kev txhawb nqa raws li kev tsim qauv sib txawv.
