Taw qhia
Relays yog qhov tseem ceeb thiab tseem ceeb ntawm cov khoom siv hluav taws xob tswj hauvzogsystems thiab automation tswj. Muaj ntau ntau yam ntawm relays, tab sis ob ntawm cov uas yuav tsum tau tham ntawm no muaj xws li voltage relays thiab tam sim no relays. Txhua hom relay muaj nws qhov kev ua haujlwm thiab daim ntawv thov scenarios. Daim ntawv no yuav ua kom muaj kev sib piv thiab kev soj ntsuam ntxaws txog cov ntsiab lus, kev ua haujlwm, kev ua haujlwm, kev faib tawm, kev siv, thiab lwm yam ntawm qhov hluav taws xob.relaysthiab tam sim no relays los pab cov neeg nyeem nkag siab thiab xaiv hom relays tsim nyog.
Txhais thiab Ua Haujlwm
Voltage relay, raws li cov cuab yeej tswj hluav taws xob, ua tiav kev tswj xyuas hluav taws xob thiab kev tiv thaiv raws li kev ntsuas qhov ntsuas hluav taws xob hauv Circuit Court. Voltage relays feem ntau yog nruab nrog lub kaw lus tswj (hu ua input circuit) thiab tswj qhov system (hu ua hluav taws xob hluav taws xob). Feem ntau, lawv tau ua hauj lwm raws li pib cov ntsiab lus rau kev tiv thaiv dhau-voltage lossis tsis tshua muaj hluav taws xob kaw hauv cov khoom siv tiv thaiv relay ntawm cov tshuab hluav taws xob, transformers, thiab cov kab sib kis.
Lub luag haujlwm tseem ceeb ntawm cov hluav taws xob hluav taws xob muaj xws li kev tswj hwm tsis siv neeg, kev tiv thaiv kev nyab xeeb, thiab kev hloov pauv hluav taws xob. Thaum qhov hluav taws xob nyob rau hauv Circuit Court dhau los yog poob qis dua tus nqi teev, qhov hluav taws xob relay tuaj yeem txiav tawm sai sai los yog txuas lub voj voog kom tiv thaiv lub cuab yeej los ntawm kev puas tsuaj. Tsis tas li ntawd, qhov hluav taws xob relays tuaj yeem ua tiav lub hom phiaj ntawm kev hloov pauv tsis siv neeg ntawm Circuit Court raws li qhov hloov pauv ntawm qhov hluav taws xob hauv Circuit Court.
Lub relay tam sim no yog lwm yam khoom siv hluav taws xob tseem ceeb uas tswj thiab tiv thaiv cov circuits los ntawm kev saib xyuas cov kev hloov pauv tam sim no hauv Circuit Court. Tam sim no relays kuj muaj ob lub tshuab tswj thiab tswj thiab feem ntau siv nyob rau hauv kev tiv thaiv relay circuits rau overload thiab luv Circuit Court ntawm motors, transformers, thiab kis kab.
Lub luag haujlwm tseem ceeb ntawm qhov tam sim no relay yog txhawm rau txheeb xyuas qhov loj thiab qhov sib txawv ntawm cov teeb liab tam sim no, thiab txiav tawm lub voj voog nyob rau hauv cov ntaub ntawv dhau los yog tsawg dua tam sim no los ntawm cov nqi teeb tsa los tiv thaiv overload lossis overheating ntawm cov khoom siv. Tsis tas li ntawd, cov relays tam sim no tseem tuaj yeem ua haujlwm los saib xyuas cov khoom siv tam sim no ntawm cov khoom siv ntxiv thiab thiaj li ncav cuag cov cuab yeej siv ntxiv hauv kev ua haujlwm zoo los yog hauv kev tswj kev txuag hluav taws xob ua tsaug rau kev tswj tsis siv neeg.
Txoj cai ua haujlwm
Voltage relay
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm qhov hluav taws xob relay yog raws li kev hloov pauv ntawm qhov hluav taws xob hauv Circuit Court kom ua rau qhov kev txiav txim ntawm lub relay. Thaum qhov hluav taws xob hauv Circuit Court dhau los yog poob qis dua tus nqi, lub tshuab hluav taws xob hluav taws xob ntawm qhov hluav taws xob relay yuav tsim cov hluav taws xob sib txuas, yog li hloov pauv lub xeev ntawm cov neeg sib cuag. Tshwj xeeb, thaum qhov hluav taws xob nce mus txog qhov teeb tsa tus nqi, cov tub ntxhais hlau yuav nyiam tus nplaig, lub relay yuav ua, cov neeg sib cuag yuav kaw lossis qhib, thiab kev tswj xyuas Circuit Court yuav qhib thiab kaw.
Voltage relays tuaj yeem muab faib ua overvoltage relays thiab undervoltage relays raws li cov tswv yim thiab cov yam ntxwv ntau. Tus qub ua thaum tus nqi hluav taws xob nce thiab nce mus txog tus nqi teeb tsa, thaum lub sijhawm kawg ua thaum tus nqi hluav taws xob txo qis thiab nce mus txog tus nqi teev.
Tam sim no relay
Lub hauv paus ntsiab lus ntawm kev ua haujlwm tam sim no yog ua raws li kev hloov pauv tam sim no hauv Circuit Court kom ua rau qhov kev txiav txim ntawm relay. Thaum cov tam sim no nyob rau hauv Circuit Court dhau los yog poob qis dua tus nqi, lub electromagnetic system ntawm lub tam sim no relay yuav tsim cov electromagnetic quab yuam, yog li hloov lub on / off lub xeev ntawm cov neeg. Tshwj xeeb tshaj yog, thaum tam sim no ncav cuag lossis tshaj qhov nqi teev, tus relay yuav qhib, kaw qhov kev sib cuag dynamic thiab disconnecting dynamic hu. Thaum qhov tam sim no poob rau 0.8 npaug ntawm tus nqi teeb tsa, qhov kev xa rov qab rov qab, qhov kev sib tiv tauj qhib, thiab kev sib cuag dynamic kaw.
Tam sim no relays yuav muab faib ua electromagnetic tam sim no relays thiab static tam sim no relays raws li lawv cov yam ntxwv hom; Raws li txoj kev teeb tsa, nws tuaj yeem muab faib ua cov tsheb ciav hlau tam sim no thiab cov khoom siv tam sim no; Raws li kev ua tam sim no, nws tuaj yeem muab faib ua overcurrent relays thiab undercurrent relays.
Classification thiab yam ntxwv
Kev faib tawm
Voltage relays thiab tam sim no relays zoo ib yam nyob rau hauv qee txoj kev hais txog kev faib tawm; txawm li cas los xij, lawv kuj muaj lawv qhov sib txawv. Lawv tshwm sim raws li cov ntaub ntawv electromagnetic thiab static rau ob qho tib si. Raws li cov qauv tsim, muaj cov qauv ruaj khov, protruding plug-in qauv, inlay plug-in qauv, rail qauv, thiab lwm yam. Txawm li cas los xij, raws li hom kev ua haujlwm voltage thiab tam sim no, voltage relays tau muab faib ua overvoltage relays thiab qis. -voltage (undervoltage) relays, thaum tam sim no relays yuav muab faib ua overcurrent relays thiab under-tam sim no relays.
yam ntxwv
Txawm li cas los xij, voltage relays thiab tam sim no relays qhia qhov sib txawv ntawm qee cov ntsiab lus. Voltage relays muaj lawv cov ntawv thov tseem ceeb hauv cov hluav taws xob me me rau lub hom phiaj ntawm kev tswj cov khoom siv hluav taws xob tsawg, hloov cov cim hluav taws xob tsawg, thiab lwm yam, thaum cov hluav taws xob tam sim no tsim nyog rau cov khoom siv tam sim no, kev tswj lub cev muaj zog, thiab lwm yam kev siv tam sim no. Tsis tas li ntawd, qhov hluav taws xob relays feem ntau txais kev sib txuas sib txuas thiab txuas nrog cov khoom thauj khoom nyob rau hauv parallel hauv Circuit Court, thaum lub sij hawm tam sim no relays txais yuav cov kev sib txuas ntawm series feem ntau thiab txuas nrog cov load hauv series hauv Circuit Court.
Daim ntawv thov scenarios
Voltage relay
Voltage relays feem ntau yog siv rau cov xwm txheej uas qhov kev hloov hluav taws xob yuav tsum tau taug qab thiab tswj xyuas hauv circuits. Siv lub zog hluav taws xob ua piv txwv, nyob rau hauv nws cov khoom siv tiv thaiv relay rau cov tshuab hluav taws xob, hloov pauv, thiab cov kab sib kis, cov hluav taws xob hluav taws xob tuaj yeem ua haujlwm pib rau kev tiv thaiv dhau-voltage lossis qis-voltage lock-out functions. Tsis tas li ntawd, qhov hluav taws xob relays tuaj yeem siv rau kev tswj hluav taws xob qis, hluav taws xob qis hloov pauv, thiab lwm yam.
Tam sim no relay
Tam sim no, relays pom cov ntawv thov dav dav hauv cov xwm txheej uas xav tau kev soj ntsuam thiab tswj cov kev hloov pauv hauv tam sim no los ntawm circuits. Piv txwv li, nyob rau hauv cov ntaub ntawv ntawm overloading thiab luv luv circuiting relay tiv thaiv circuits rau hluav taws xob motors, transformers, thiab kis kab mob, tam sim no relays tiv thaiv qhov teeb meem no los ntawm kev cuam tshuam lub Circuit Court ceev kom tsis txhob overloading, cua sov, los yog lwm yam teeb meem uas yuav tshwm sim. hauv cov khoom siv. Ntxiv mus, tam sim no relays uas twb muaj lawm nyob rau hauv lub neej tuaj yeem tau txais los saib xyuas cov khoom siv tam sim no ntawm cov khoom siv ntxiv thiab yog li paub txog kev tswj tsis siv neeg thaum lub sijhawm ua haujlwm zoo lossis kev tswj xyuas lub zog.
Cov ntsiab lus
Hauv cov ntsiab lus, muaj qhov sib txawv tseem ceeb ntawm voltage relays thiab tam sim no relays nyob rau hauv cov nqe lus ntawm lub ntsiab lus, kev ua haujlwm, lub hauv paus ntsiab lus ntawm kev ua haujlwm, kev faib tawm, thiab daim ntawv thov scenarios. Voltage relays feem ntau yog siv los saib xyuas thiab tswj cov kev hloov hluav taws xob hauv circuits, thiab tsim nyog rau cov kev sib txuas me me thiab kev sib txuas ua ke; Tam sim no relays feem ntau yog siv los saib xyuas thiab tswj cov kev hloov pauv tam sim no hauv circuits, thiab tsim nyog rau cov khoom siv tam sim no thiab cov kev sib txuas ua ke. Hauv kev siv tswv yim, peb yuav tsum xaiv hom relay tsim nyog raws li cov kev xav tau tshwj xeeb thiab cov xwm txheej kom ntseeg tau tias kev ua haujlwm ruaj khov thiab kev nyab xeeb.kev tiv thaivntawm Circuit Court.
