Nyob rau hauv cov qauv ntawm ib tug relay, cov tub ntxhais hlau thiab armature ua ke ua ib tug ua tiav magnetic Circuit Court system, uas yog cov tseem ceeb tivthaiv rau converting hluav taws xob teeb liab mus rau hauv txhua yam kev ua. Rau ntau hom Core rau Electromagnetic Relays, qhov zoo ntawm qhov tsim hluav taws xob sib nqus ncaj qha txiav txim siab cov lus teb ceev, kev sib koom ua ke, thiab kev ua neej nyob. Yog li ntawd, kev nkag siab tob ntawm cov tub ntxhais hlau txoj haujlwm ua haujlwm los ntawm qhov kev xav ntawm electromagnetic yog qhov tseem ceeb rau kev tsim cov khoom tsim.
Thaum lub relay coil yog energized, tam sim no ntws los ntawm lub kauj, tsim ib tug magnetic teb nyob ib ncig ntawm lub winding raws li lub hauv paus ntsiab lus ntawm electromagnetic induction. Qhov no magnetic teb yog concentrated thiab coj los ntawm lub Relay Coil Core, tsim ib tug sib nqus flux nyob rau hauv lub hlau core thiab kaw raws li tsim magnetic circuits. Nyob rau hauv cov txheej txheem no, cov tub ntxhais hlau, raws li tus neeg xyuas pib sib nqus, muaj nws cov khoom siv thiab cov qauv tsim ncaj qha cuam tshuam rau qhov sib nqus flux ntom ntom.
Hauv kev sib nqus hluav taws xob, feem ntau muaj qhov sib txawv ntawm huab cua ntawm cov tub ntxhais hlau thiab lub armature. Thaum cov magnetic flux dhau los ntawm qhov sib txawv ntawm huab cua no, electromagnetic attraction yog generated ntawm lawv. Qhov kev nyiam no yog qhov tseem ceeb rau kev tsav lub relay txoj haujlwm, thiab nws qhov loj tuaj yeem piav qhia los ntawm classical electromagnetic txoj kev xav, uas yog Maxwell txoj cai ntawm electromagnetic attraction. Cov mis no qhia tau hais tias lub zog quab yuam yog proportional rau lub square ntawm magnetic flux ceev nyob rau hauv cov huab cua sib txawv thiab cheeb tsam ntawm kev ua, thiab kuj muaj feem xyuam rau cov magnetic permeability.
Los ntawm cov ntaub ntawv kev xav, cov tub ntxhais hlau feem ntau siv siab - cov khoom siv hlau nplaum purity, xws li Hluav Taws Xob Pure Iron Core lossis DT4C Iron Core. Cov ntaub ntawv no muaj cov permeability siab thiab tsis tshua muaj coercivity, ua kom muaj kev lag luam sai sai ntawm cov tam sim no qis thiab ceev demagnetization thaum lub zog poob, yog li ua kom cov relay siab - zaus teb muaj peev xwm. Cov yam ntxwv no tshwj xeeb yog qhov tseem ceeb hauv Soft Magnetic Iron Cores rau Relays.
Los ntawm kev tsim qauv kev xav, kev tswj cov huab cua sib txawv hauv qhov sib nqus hluav taws xob yog qhov tseem ceeb. Qhov sib txawv ntawm huab cua loj heev ua rau muaj kev sib nqus tsis txaus, txo cov electromagnetic attraction; qhov sib txawv me me heev yuav ua rau muaj teeb meem kev cuam tshuam los yog adhesion. Yog li ntawd, qhov sib npaug yuav tsum raug ntaus ntawm qhov sib nqus kev ua tau zoo thiab kev ntseeg tau ntawm cov neeg kho tshuab thaum tsim cov txheej txheem tseem ceeb xws li Core Pin thiab Relay Pin.
Sib nqus saturation kuj yuav tsum tau txiav txim siab hauv kev tsim hluav taws xob sib nqus. When the magnetic flux density exceeds the material's carrying capacity, the iron core will enter a saturated state, leading to a decrease in permeability and affecting the stability of the electromagnetic attraction. Yog li ntawd, nyob rau hauv Relay steel core tsim, lub zos saturation feem ntau yog zam los ntawm tsim nyog nce tus ntoo khaub lig-sectional cheeb tsam los yog optimizing lub magnetic Circuit Court qauv.
Tsis tas li ntawd, thaum lub relay yog de{0}}energized, lub magnetic flux ploj mus sai heev, lub armature rov qab nyob rau hauv lub caij nplooj ntoos hlav quab yuam, thiab kev sib cuag qhib. Cov txheej txheem no yuav tsum muaj cov tub ntxhais hlau kom muaj cov khoom zoo heev demagnetizing los tiv thaiv cov hlau nplaum seem los ntawm kev cuam tshuam rau kev ua haujlwm raug. Yog li ntawd, Pure Iron Core cov ntaub ntawv muaj qhov zoo dua hauv qhov no.
Nyob rau hauv niaj hnub relay tsim, Soft Magnetic Iron Cores rau Relay tsis tsuas yog ua lub luag haujlwm ntawm cov hlau nplaum, tab sis kuj yuav tsum xav txog kev txhawb nqa thiab kev sib dhos. Precise kev koom tes nrog lwm yam structural Cheebtsam ua kom ruaj khov sib nqus Circuit Court kaw thaum txo qhov kev cuam tshuam ntawm mechanical vibration ntawm kev ua tau zoo.
Zuag qhia tag nrho, cov tub ntxhais hlau relay tsis yog ib qho yooj yim sib nqus sib nqus, tab sis cov tub ntxhais txuas txuas ntawm electromagnetic thiab mechanical systems. Los ntawm tiam ntawm electromagnetic attraction mus rau lub realization ntawm kev sib cuag actuation, cov tub ntxhais hlau yog ib txwm nyob rau hauv ib tug tseem ceeb txoj hauj lwm. Nws cov khoom xaiv, kev tsim qauv, thiab kev tsim khoom txhua tus muaj kev cuam tshuam loj heev rau kev ua haujlwm ntawm relay.
