Qhov kev xaiv ntawm relay ntawm daim duab lossis hauv daim ntawv yog tsim nyog kom cov kws tshaj lij tuaj yeem nrhiav tau yooj yim. Raws li twb tau hais lawm, nyob rau hauv cov ntaub ntawv ntawm ib tsab ntawv xaiv, K yog siv. Txawm li cas los, nws yog tsim nyog hais nyob rau hauv no hais tias muaj xws li kos duab raws li hluav taws xob tus thawj tswj hwm los yog tsuas yog hluav taws xob kos duab uas tsis siv cov npe ntawv. Nyob rau hauv cov ntaub ntawv no, lub cim ntawm relay nyob rau hauv graphical daim ntawv yog siv. Tom qab ntawd tus relay yuav raug piav raws li lub duab plaub, los ntawm cov sab loj uas ib tus neeg sib cuag tawm mus.

Dab tsi yog rel

Ib qho relay yog ib qho khoom siv hloov pauv, lossis tsuas yog KU. Lub hom phiaj tseem ceeb ntawm cov khoom no yog txhawm rau txuas lossis txiav lub voj voog ntawm cov hluav taws xob lossis hluav taws xob hluav taws xob nyob rau hauv qhov xwm txheej uas cov khoom siv tam sim no hloov pauv hauv ib txoj hauv kev. Raws li rau qhov kev siv, thawj zaug cov cuab yeej no ua haujlwm ua haujlwm tau siv hauv xov tooj. Kev siv hluav taws xob thiab hluav taws xob hluav taws xob tuaj tom qab ntau.

khoom siv

Nws yog tsim nyog hais tias qhov kev xaiv ntawm relay nyob rau hauv tsab ntawv K yog siv tsis tshua muaj, txij li hnub no muaj ntau ntau yam ntawm cov cuab yeej no, thiab lawv muaj ib tug txawv kev xaiv. Txawm li cas los xij, cov cuab yeej pib ntawm cov cuab yeej no yog kwv yees li qub.

Lub relay yog ib lub kauj uas tsis muaj hlau nplaum. Ib tug tooj liab hlau nrog ntaub los yog hluavtaws rwb thaiv tsev yog qhov txhab ntawm lub hauv paus no. Txawm li cas los xij, feem ntau siv dielectric kua roj vanish txheej. Nyob rau hauv lub kauj, uas sawv ntawm lub hauv paus uas tsis yog-conductive, ib tug hlau core yog muab tso rau. Tsis tas li ntawd, muaj cov khoom xws li springs, armature, contactors thiab connectors.

Yog tias tsab ntawv xaiv ntawm kev xa xov tsuas yog ib tsab ntawv K, ces lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov cuab yeej no yog raws li hauv qab no. Thaum tam sim no siv rau lub solenoid winding, cov tub ntxhais yuav pib nyiam lub armature. Txij li thaum cov khoom yog hlau, thaum lawv txuas nrog, lub Circuit Court yuav kaw. Yog tias lub zog tam sim no pib tsis muaj zog, tom qab ntawd ntawm qee theem lub zog ntawm lub caij nplooj ntoos hlav yuav loj dua, vim tias nws yuav thawb lub armature rov qab thiab lub voj voog yuav qhib. Los ntawm nws tus kheej, lub relay yuav ua hauj lwm heev sharply. Txhawm rau ua kom qhov smoothness thiab raug ntawm kev ua haujlwm, cov resistors feem ntau yog ntxiv rau hauv Circuit Court, thiab cov capacitors yog siv los tiv thaiv cov cuab yeej los ntawm ib qho surges.

Nyob rau hauv luv luv, lub npe ntawm relay nrog tsab ntawv K txhais tau hais tias qhov no yog cov khoom siv yooj yim tshaj plaws uas ua haujlwm ntawm lub hauv paus ntsiab lus ntawm qhov yooj yim electromagnetic induction. Txaus txausTxoj kev yooj yim ntawm kev ua haujlwm, nws suav tias yog kev ntseeg siab heev.

Relay specifications

Cov cuab yeej no muaj ob peb yam tseem ceeb uas koj yuav tsum xyuam xim rau.

  1. Qhov kev ntsuas no yog qhov tseem ceeb heev. Nws yuav txiav txim siab npaum li cas tam sim no xav tau los ua kom cov relay ua haujlwm.
  2. Nws muaj tus yam ntxwv zoo li qhov tsis kam ntawm electromagnet winding.
  3. Txhua lub cuab yeej muaj nws tus kheej qhov pib rau kev hloov mus rau thiab tawm ntawm lub voj voog. Hauv lwm lo lus, txhua tus relay muaj nws tus kheej yam tsawg kawg nkaus tam sim no rau tripping thiab tripping.
  4. Yuav muaj tus yam ntxwv zoo li lub sijhawm nyiam thiab lub sijhawm rov qab los ntawm lub thauj tog rau nkoj.

Relay electromagnetic type

Ib qho ntawm ntau hom yog ib qho hluav taws xob relay. Qhov KU no belongs rau hom electromechanical, thiab lub hauv paus ntsiab lus ntawm kev ua haujlwm yog raws li qhov tseeb tias cov hlau nplaum uas tau tsim nyob rau hauv hom zoo li qub winding cuam tshuam nrog armature. Xws li cov cuab yeej, nyob rau hauv lem, muab faib ua ob hom. Thawj yog electromagnetic, uas tsuas yog teb rau qhov loj ntawm cov khoom tam sim no. Qhov thib ob yog polarized, uas ob qho tib si cov khoom tam sim no thiab nws cov polarity yog qhov tseem ceeb. Raws li tsab ntawv xaiv ntawm relay, tsab ntawv K tseem tuaj yeem tso tawm ntawm no, yog tias peb tham txog daim ntawv thov, feem ntau lawv tau siv rau hauv kev tswj Circuit Court. Hauv kev lag luam, cov khoom siv no yog nyob rau hauv ib qho chaw nruab nrab ntawm cov khoom siv tam sim no thiab cov khoom siv qis tam sim no.

KU nrog AC tam sim notype

Raws li koj tuaj yeem pom los ntawm lub npe, hom relay no tau qhib thaum AC siv rau cov khoom siv nkag. Raws li rau lub npe ntawm qhov hluav taws xob relay, nws feem ntau hu ua KV. Cov cim no siv tau rau yuav luag txhua hom, vim yuav luag txhua tus ua haujlwm nrog cov tswv yim tam sim no thiab nws qhov voltage.

Raws li rau AC KU, qhov no yog ib qho khoom siv uas muaj kev tswj cov theem hloov mus txog xoom lossis tsis muaj nws. Cov khoom siv yog ib qho kev sib dhos ntawm cov qauv xws li thyristor block, rectifier diode block thiab tswj circuits. Nws tseem tsim nyog sau cia tias lawv tuaj yeem ua tau ntawm ob hom, sib txawv ntawm lub hauv paus modular uas lawv tau tsim. Tej zaum yuav muaj hom transformer lossis optical cais. Raws li rau daim ntawv thov, ces, ntawm chav kawm, lawv yog siv nyob rau hauv sib txawv tes hauj lwm nrog ib tug siab tshaj plaws voltage ntawm 1.6 kW. Raws li qhov tam sim no, nws tus nqi yuav tsum tsis pub tshaj 320 A.

Cais, nws tsim nyog hais txog cov khoom siv uas tsim los rau 220 V tes hauj lwm, vim lawv tsis tuaj yeem ua haujlwm yam tsis muaj cov khoom siv zoo li no. Cov khoom siv zoo li no yog siv yog tias xav tau kaw lossis qhib kev sib cuag ntawm hom multidirectional. Ib qho piv txwv yog ib qho cuab yeej uas teeb pom kev hauv cheeb tsam thiab muaj lub suab sensor. Tom qab ntawd nws hloov tawm tias ib qho ntawm cov khoom siv txuas nrog lub zog, thiab lwm qhov rau lub sensor.

KU nrog tam sim no

Ntxiv rau cov khoom siv no, xws li lub sijhawm relays kuj tseem siv, qhov kev xaiv uas yog KT.

DC hloov khoom siv tuaj yeem ua taupolarized los yog nruab nrab hom. Qhov txawv yog tias cov khoom siv polarized rhiab heev rau qhov polarity ntawm cov khoom siv hluav taws xob. Nyob ntawm cov ncej no, KU thauj tog rau nkoj tuaj yeem hloov nws txoj kev txav mus los. Qhov nruab nrab tsis nyob ntawm qhov ntsuas no. Feem ntau, cov khoom siv no tsuas yog siv yog tias nws tsis tuaj yeem txuas mus rau lub network hloov pauv tam sim no.

Qhov no yog vim qhov tseeb tias tus nqi ntawm cov khoom siv no siab dua nrog cov hloov pauv tam sim no, nrog rau qhov xav tau los txuas lub zog rau kev ua haujlwm ib txwm muaj.

khoom siv hluav taws xob

Ntxiv rau cov khoom siv tam sim no, kuj tseem muaj hluav taws xob lossis thermal hom. Piv txwv li, lub npe ntawm thermal relay KK. Lub Scope ntawm nws daim ntawv thov kuj yog heev meej, raws li lub npe qhia. Ua tib zoo mloog ntau rau cov khoom siv hluav taws xob.

Raws li rau kev tsim thiab kev ua haujlwm, lawv tsis txawv ntawm electromechanical. Qhov tseem ceeb sib txawv nyob rau hauv qhov tseeb hais tias nyob rau hauv cov ntaub ntawv no ib tug semiconductor hom diode yog siv los ua tag nrho cov tsim nyog functions. Kev siv ntau tshaj plaws ntawm cov khoom siv no yog nyob rau hauv tsheb, uas feem ntau ntawm cov haujlwm tau ua los ntawm kev siv hluav taws xob relay tswj units. Tseem tsis tau muaj peev xwm tso tseg lawv txoj kev siv.

Device manufacturers

Hnub no, muaj ntau lub tuam txhab tsim cov khoom zoo li no, tab sis koj yuav tsum tau them sai sai rauib txhia.

Piv txwv li, ntawm cov tuam txhab European, qhov thib peb yog nyob los ntawm German tuam txhab hu ua Finder. Nws tau koom nrog hauv kev tsim cov khoom siv xws li cov hom phiaj dav dav, lub xeev ruaj khov, lub zog, lub sijhawm relays. Kuj tseem muaj lub siab hloov pauv, lub npe uas yog KP.

Yog tias peb tham txog cov neeg tsim khoom hauv tsev, peb tuaj yeem tso tawm JSC NPK Severnaya Zarya. Lub tuam txhab no tau koom nrog hauv kev tsim cov thauj tog rau nkoj electromagnetic qauv ntawm kev hloov hom. Lub hom phiaj tseem ceeb yog thaj chaw muaj thiab tshwj xeeb ntawm kev lag luam. Raws li rau lub npe ntawm tus relay, nyob rau hauv cov ntaub ntawv no nws yog K, txij li thaum lawv koom rau ib hom.

muaj cov chaw tsim khoom los ntawm Nyiv. Lub tuam txhab hu ua Omran thiab koom nrog hauv kev tsim cov khoom siv xws li cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob. Tsis tas li ntawd, lawv kuj tsim cov khoom xws li cov khoom siv hluav taws xob qis qis.

Cov kab ua ntej tau tuav tau ntev los ntawm cov khoom lag luam los ntawm Asmeskas tuam txhab American Zettler. Lub tuam txhab tau koom nrog kev tsim tawm txog 40 ntau hom CU, uas tsim nyog rau ntau lub hom phiaj.
