Sib nqus latching relay yog ib qho kev hloov pauv tsis siv neeg uas siv lub zog sib nqus ntawm cov hlau nplaum ruaj khov los tswj nws txoj kev sib cuag. Tsis zoo li ib txwm siv hluav taws xob hluav taws xob relays - uas yuav tsum muaj lub zog txuas ntxiv los txhawb lub zog ntawm lub zog -ib lub tshuab nqus hlau nplaum yuav tsum tsuas yog luv luv tam sim no mem tes hloov lub xeev, tso siab rau cov hlau nplaum ntawm cov hlau nplaum ruaj khov txhawm rau txhawm rau qhov chaw sib cuag thaum lub zog raug tshem tawm. Qhov "bistable" tus yam ntxwv no ua rau nws muaj txiaj ntsig zoo ntawm kev txuag hluav taws xob thiab lub xeev nco.
Cov Ntsiab Cai Ua Haujlwm
Lub hauv paus ntawm cov hlau nplaum sib nqus relay yog nyob rau hauv kev tsim ntawm nws cov magnetic circuit system, uas feem ntau muaj ib tug txias - taub hau ntshiab hlau core, ib tug quab, armature, thiab ib tug mus tas li hlau nplaum. Nws txoj haujlwm tuaj yeem nkag siab tias yog txheej txheem lub cev uas cuam tshuam nrog kev sib nqus ntawm thaj chaw sib nqus:
Teeb (Latching) txheej txheem
Thaum muaj qhov zoo DC voltage mem tes siv rau lub kauj, lub kauj yuav ua kom muaj zog thiab ua kom muaj qhov sib nqus. Daim teb no cuam tshuam nrog cov hlau nplaum ntawm cov hlau nplaum ruaj khov- qhov twg zoo li cov ncej tiv thaiv thiab tsis zoo li cov ncej nyiam- tsav lub armature txav thiab ua rau cov neeg raug kaw. Thaum cov mem tes xaus, lub zog rau lub kauj raug txiav tawm; Txawm li cas los xij, lub zog sib nqus ntawm cov hlau nplaum ruaj khov tuav lub armature nyob rau hauv qhov chaw, yog li tswj cov kev sib cuag hauv lub xeev kaw.
Rov pib dua (tso tawm) txheej txheem
Thaum nws yog qhov tsim nyog los qhib cov neeg sib cuag, rov qab DC voltage mem tes yog siv rau lub kauj. Qhov rov qab magnetic teb generated los ntawm coil counteracts los yog tsis muaj zog tuav lub zog ntawm cov hlau nplaum ruaj khov; lub armature ces rov qab mus rau nws qhov qub chaw-tsav los ntawm lub caij nplooj ntoos hlav rov qab los yog nws qhov hnyav- thiab cov neeg sib cuag qhib. Thaum cov mem tes dissipates, lub relay tseem ruaj khov nyob rau hauv lub xeev qhib.
Txhawm rau ua kom yooj yim rau kev tsim ntawm lub voj voog tsav, ob lub -coil qauv yog nquag siv hauv cov ntawv thov. Ib lub kauj ( "teeb" coil) yog tshwj xeeb rau kev ua haujlwm latching, thaum lwm lub kauj ("rov pib dua" kauj) tshwj xeeb rau kev tso tawm. Qhov kev tsim no tshem tawm qhov nyuaj uas cuam tshuam nrog kev hloov cov kev taw qhia ntawm cov dej ntws tam sim no hauv ib qho -coil configuration, yog li txhim kho kev ntseeg siab ntawm kev tswj hwm.
Cov ntaub ntawv tseem ceeb: Daim ntawv thov ntawm mos sib nqus Alloys thiab Pure Iron
Kev ua tau zoo ntawm kev sib nqus latching relay feem ntau nyob ntawm cov khoom sib nqus ntawm cov ntaub ntawv tseem ceeb hauv nws cov kab hluav taws xob sib nqus. Cov ntaub ntawv no, feem ntau hu ua "cov ntaub ntawv sib nqus mos," yog tus cwj pwm los ntawm lawv qhov yooj yim ntawm magnetization thiab demagnetization, ua rau lawv ua tau zoo thiab teb rau cov kev hloov hauv magnetic teb.
Kev ua haujlwm thiab cov khoom siv ntawm cov tub ntxhais hlau
Lub Soft Sib Nqus Hlau Qws (xws li, RFe80) ua haujlwm raws li lub substrate nyob ib ncig ntawm lub coil yog qhov txhab, nrog rau lub hauv paus ntsiab lus rau magnetic flux. Thaum lub coil yog energized, Pure Iron Rod rau lub Relay yog magnetized sai heev, tsim ib tug haib electromagnetic quab yuam. Yuav kom ua tiav siab rhiab heev thiab lub sij hawm teb sai, cov khoom yuav tsum muaj siab sib nqus permeability thiab qis coercivity. Cov ntaub ntawv no yog zoo li tus thiab tsim siv tus txheej txheem "Relay Core Cold Heading", uas ua kom muaj qhov sib xws ntawm cov nplej hauv cov khoom siv, yog li yielding superior magnetic zog thiab txhua yam muaj zog. Piv txwv li, ib qho khoom siv siv nickel-plated relay core tsis tsuas yog muaj cov khoom sib nqus ruaj khov, tab sis nws cov plating nto kuj zoo tiv thaiv oxidation, kom ntseeg tau ntev -lub sij hawm kev cia siab txawm nyob rau hauv ib puag ncig hnyav.
Kev Tiv Thaiv Kev Ua Haujlwm ntawm Pure Hlau Phaj
Nyob rau hauv cov qauv tsim ntawm ib tug sib nqus latching relay-tshaj lub hauv paus Iron Core rau Relay- cov hlau ntshiab yog feem ntau nyob rau ntawm qhov kawg ntawm lub phaj mounting los yog nyob rau hauv periphery ntawm lub magnetic circuits. Cov hlau ntshiab no ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev sib nqus. Vim yog cov hlau ntshiab uas tshwj xeeb tshaj yog sib nqus permeability, nws tuaj yeem "txim" thiab muaj cov dej ntws tawm thaum lub sij hawm relay ua haujlwm nyob rau hauv nws tus kheej, yog li tsim lub kaw magnetic Circuit Court. Qhov no ua tau zoo tiv thaiv sab nraud stray magnetic teb los ntawm kev cuam tshuam nrog lub relay lub cev ua haujlwm thiab tseem tiv thaiv lub relay tus kheej magnetic teb los ntawm kev cuam tshuam cov khoom siv hluav taws xob nyob ib puag ncig. Qhov kev tsim no yog qhov tseem ceeb rau kev txhim kho kev tiv thaiv - muaj peev xwm cuam tshuam ntawm siab - cov khoom siv kev ntseeg siab, xws li Pure Iron Cores rau Railway Signaling Relays.
Kev xaiv cov khoom siv rau Armatures thiab Yokes
Lub armature thiab tus quab yog qhov tseem ceeb ntawm cov khoom sib nqus. Lub armature yog cov khoom sib nqus sib nqus, qhov txav ntawm qhov ncaj qha actuates hloov ntawm cov neeg sib cuag; lub yoke, conversely, constituted lub moj khaum taag ntawm lub magnetic Circuit Court. Cov khoom no feem ntau yog tsim los ntawm cov hlau nplaum mos mos-xws li Cov Hlau nplaum nplaum nplaum rau Relays- kom ntseeg tau tias qhov sib nqus tsis kam ntawm tag nrho cov hluav taws xob raug txo qis thiab qhov ua tau zoo ntawm kev sib nqus flux kis tau zoo.
Raws li kev lag luam ntawm kev tswj hluav taws xob hloov mus rau qhov me me, kev siv hluav taws xob tsawg, thiab kev ua haujlwm ntse, daim ntawv thov scenarios rau latching relays tau teem kom nthuav dav ntxiv, nrog rau cov kev xav tau nce ntxiv rau lawv qhov kev ua tau zoo. Tau txais kev nkag siab zoo ntawm cov hauv paus ntsiab lus thiab cov ntsiab lus tseem ceeb ntawm kev thov rau latching relays yog qhov tseem ceeb ntawm cov tswv yim; nws ua kom yooj yim xaiv cov khoom tsim nyog thiab kev siv kom raug, yog li txhim kho kev ruaj ntseg thiab kev ntseeg siab ntawm cov hluav taws xob tswj circuits.
