1. Lub hauv paus ntsiab lus ntawm relay
Relay yog ib hom kev hloov khoom siv uas tuaj yeem hloov lub teeb liab ntawm ib lub voj voog mus rau lwm lub voj voog. Nws yog feem ntau tsim los ntawm peb ntu: electromagnetic system, electrostatic system thiab mechanical system. Lub tshuab hluav taws xob nqus hluav taws xob yog tsim los ntawm lub kauj kom kaw lossis tawg qhov kev sib cuag, thiaj li tswj tau ntawm thiab tawg lossis kev tswj ntawm cov khoom tswj (xws li lub teeb hluav taws xob, lub zog tsav, thiab lwm yam). Thaum lub voltage los yog tam sim no ntawm lub Circuit Court ncav cuag tus nqi ntawm cov relay, cov tub ntxhais nyob rau hauv lub coil generates ib tug muaj zog magnetic teb, thiaj li hais tias ib tug siab tam sim no los yog voltage tso zis nyob rau hauv kev sib cuag ntawm nws, yog li realizing lub switching tswj. lub Circuit Court.
2. Tsav cov lus qhia kev teeb tsa hauv Circuit Court
1. Lub hwj huam mov coil yuav tsum raug cais tawm ntawm lub relay coil
Nws yog qhov zoo dua los cais lub zog hluav taws xob los ntawm cov xaim hluav taws xob los yog muab tso rau hauv qhov kev sib cais kom tsis txhob muaj qhov hluav taws xob siab lossis siab tam sim no ntawm lub zog hluav taws xob los ntawm kev cuam tshuam lossis hlawv rau lub relay coil.
2. Tiv tauj txoj kev ntawm relay coil
Thaum lub relay coil txuas, lub coil polarity yuav tsum tau ua raws li, txwv tsis pub lub kauj yuav tsis ua haujlwm zoo. Qhov zoo thiab rov qab polarity yuav tsum tau cim kom meej ntawm ob qho kawg ntawm lub kauj.
3. Kev teeb tsa ntawm lub bypass capacitor
Relys zoo li ua suab nrov, tshwj xeeb tshaj yog nyob rau hauv qhov chaw siab lossis qhov chaw siab tam sim no. Txhawm rau kom tsis txhob muaj kev cuam tshuam zoo li no, lub bypass capacitor tuaj yeem muab tso rau ntawm qhov kawg ntawm lub relay coil kom txo tau cov suab nrov cuam tshuam.
4. Muab cov neeg sib cuag virtual
Kev sib cuag virtual tuaj yeem muab faib rau hauv cov neeg kho tshuab kev sib cuag, txo qhov cuam tshuam quab yuam ntawm Circuit Court, yog li txhim kho lub neej ntawm relay.
5. impedance txuam ntawm lub rooj tsav xwm Circuit Court
Lub winding ntawm lub rooj tsavxwm Circuit Court yuav ua rau impedance tsis sib haum ntawm lub Circuit Court, xws li inductance thiab capacitors, uas yuav cuam tshuam rau kev hloov pauv ntawm cov relay. Txhawm rau kom muaj kev ruaj ntseg, tsim nyog impedance txuam ntawm txhua yam hauv lub cev.
6. Optical coupling thiab kev sib cais
Txhawm rau kom tsis txhob muaj qhov hluav taws xob siab thiab qhov hluav taws xob siab tam sim no mus rau lub relay coil, lub voj voog tuaj yeem raug cais tawm siv qhov kev sib txuas ntawm qhov muag pom.
7. Kev tiv thaiv tawm kom raug
Thaum lub relay tawm lawm, lub electromagnetic teb nyob rau hauv lub coil generates ib tug rov qab voltage, uas yuav ua rau puas rau lwm yam Cheebtsam. Txhawm rau zam qhov no, ib qho rov qab diode yuav tsum tau muab tso ua kom rov qab voltage hloov mus rau hauv diode.
3. Cov ntsiab lus luv luv
Relay yog ib qho khoom siv hluav taws xob tseem ceeb thiab tau siv dav. Thaum tsim lub Circuit Court, peb yuav tsum ua raws li cov hauv paus ntsiab lus ntawm kev ruaj ntseg Circuit Court, kev cia siab, impedance txuam, thiaj li yuav ua kom muaj kev ruaj ntseg ntawm relay. Tsis tas li ntawd, qhov tseeb qhov chaw ntawm virtual hu, bypass capacitor, optical coupling isolator, thiab lwm yam, tuaj yeem txhim kho lub neej ntawm relay thiab optimize nws cov kev ua tau zoo. Raws li qhov tseeb, qhov tseeb tsav Circuit Court layout kev txawj ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ib txwm muaj thiab kev ua haujlwm ruaj khov ntawm lub sijhawm ntev.
