Nyob rau hauv automotive circuits, automotive relays yog ib qho tseem ceeb ntawm kev tswj cov khoom, ua kom lub cev ua haujlwm thiab kev nyab xeeb ntawm lub tsheb. Lawv tsis tsuas yog tswj ntau lub tsheb ua haujlwm tab sis kuj yog qhov txuas tseem ceeb hauv kev ua kom muaj kev nyab xeeb tsav tsheb. Xaiv txoj cai automotive relay tsis tuaj yeem txhim kho koj lub tsheb zoo nkaus li tab sis kuj ua lub luag haujlwm tseem ceeb hauv lub sijhawm tseem ceeb.
Automotive interiors kuj tau nruab nrog cov cuab yeej zoo ib yam li cov keyboards -relays.
Tom ntej no, thaum xaiv ib lub tsheb relay, input thiab output tsis, raws li zoo raws li ib puag ncig thiab kev nyab xeeb yam, yuav tsum tau txiav txim siab kom ua tau raws li lub tsheb txoj kev siv. Thaum xaiv cov txheej txheem, peb yuav tsum ua tib zoo xav txog ntau yam xws li input parameters, output parameters, timeless parameters, environmental conditions, and safety rules to ensure that the select relay is perfectly matched and performs its aim function.
Thaum xaiv ib lub tsheb relay, peb yuav tsum xav txog ntau yam tseem ceeb los xyuas kom meej qhov kev ua haujlwm zoo thiab kev nyab xeeb ntawm lub tsheb.
Input Parameter Xaiv Cov Cai
► Basic Parameter Focus
Thaum xaiv ib lub tsheb relay, peb yuav tsum tau tsom rau cov input tsis xws li coil rated voltage, kev khiav hauj lwm voltage, tso tawm voltage, coil zog noj, siab tshaj tam sim no, thiab coil kuj. Thaum xaiv cov txheej txheem, peb yuav tsum xyuas kom meej tias cov kev ntsuas no phim cov kev xav tau tiag tiag los lav qhov kev ua haujlwm ib txwm muaj ntawm cov relay.
► Ambient Temperature Influence
Cov kev khiav hauj lwm tsis ntawm relays sib txawv nyob rau hauv txawv kub ib puag ncig, yuav tsum tau ceev faj. Automotive relays feem ntau ua haujlwm nyob rau hauv lub cav compartment thiab cov neeg caij tsheb compartment ib puag ncig, nrog rau qhov kub siab tshaj plaws ntawm 125℃thiab 85℃feem. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias coil tsis kam hloov nrog qhov kub thiab txias, cuam tshuam rau relay lub rub- thiab tso tawm voltages.
► Voltage thiab Fais Fab Kev Txiav Txim Siab
Kev ua haujlwm siab voltage tsim yuav tsum xav txog qhov cuam tshuam ntawm qhov kub thiab txias ntawm lub kauj. Txhawm rau ua kom tau raws li qhov yuav tsum tau ua haujlwm qis, cov tsheb thauj mus los feem ntau yog tsim los nrog kev siv hluav taws xob ntau dua. Txawm li cas los xij, qhov hluav taws xob siv rau lub kauj rau ncua sij hawm yuav tsum tau tswj tsis pub dhau 120% ntawm qhov ntsuas hluav taws xob. Tshwj xeeb tshaj yog nyob rau hauv siab - qhov kub thiab txias ib puag ncig, lub kauj kub kub nce sai, ua kom nws cov txheej txheem aging.
► Tso Voltage Setting
Qhov tso tawm voltage ntawm ob qho tib si DC thiab AC relays yuav tsum nyob rau hauv qhov teeb tsa ntau yam. Yog hais tias qhov seem ntawm qhov hluav taws xob nyob rau hauv Circuit Court tshaj qhov no, lub relay yuav tsis tso tawm kom raug.
► Rov qab EMF thiab Kev Tiv Thaiv Kev Ntsuas
Xaiv cov khoom tsim nyog xws li resistors lossis freewheeling diodes tuaj yeem txo qhov cuam tshuam ntawm EMF rov qab. Txhawm rau kom tsis txhob muaj kev puas tsuaj rau cov hluav taws xob hluav taws xob los ntawm sab nraub qaum EMF, cov relays nruab nrog cov resistors lossis freewheeling diodes tuaj yeem raug xaiv, tab sis qhov tseeb fais fab mov polarity configuration yuav tsum tau ua kom ntseeg tau.
Output Parameter Xaiv Cov Cai
► Hu rau hom thiab Load
Thaum xaiv automotive relays, ntau qhov kev tso tawm yuav tsum raug txiav txim siab, suav nrog cov naj npawb ntawm cov pab pawg sib cuag, hom kev sib cuag, kev sib cuag, cov khoom siv, hluav taws xob lub neej, thiab lub neej txhua yam. Cov kev txwv no cuam tshuam ncaj qha rau lub relay qhov kev ua tau zoo thiab kev ua tau zoo. Hom kev tiv tauj raug xaiv raws li daim ntawv thov tshwj xeeb, cuam tshuam rau kev tswj xyuas Circuit Court.
► Ntau hom Loads
Relays yuav tsum muaj kev ntsuas tshwj xeeb rau cov khoom sib txawv kom tsis txhob muaj kev puas tsuaj. Ntau hom kev thauj khoom yuav muaj qhov sib txawv ntawm cov neeg sib cuag. Piv txwv li, lub teeb loads yuav tsim inrush tam sim no; lub cev muaj zog loads yuav tsim rov qab EMF; inductive loads yuav tsim electromagnetic induction surges, thiab lwm yam. Nyob rau hauv lub tswv yim daim ntawv thov, tshwj xeeb yuav tsum tau them nyiaj mloog mus rau cov yam ntxwv ntawm lub load hom, thiab cov kev ntsuas yuav tsum tau coj los tiv thaiv cov neeg.
► Hu rau cov khoom siv thiab kev tiv thaiv
Cov ntaub ntawv sib cuag yuav tsum muaj cov yam ntxwv xws li kev sib cuag tsis tshua muaj zog thiab corrosion kuj. Thaum xaiv cov ntaub ntawv sib txuas, xyuas kom meej tias qhov kev sib cuag tsis tshua muaj qis thiab ruaj khov, thiab lawv muaj qhov zoo corrosion kuj thiab tiv thaiv - adhesion zog.
Kev xaiv lub sijhawm thiab ib puag ncig
► Lub Sijhawm Tseem Ceeb Parameters
Thaum xaiv cov relays, lub sij hawm tsis xws li lub sij hawm ua hauj lwm muaj kev cuam tshuam me ntsis ntawm automotive relays, tab sis rau kev sib txuas relays, flashing zaus yuav tsum tau xav txog. Thaum lub sij hawm ua hauj lwm feem ntau tsis yog ib qho kev txhawj xeeb tseem ceeb rau automotive relays, flashing zaus thiab ncua sij hawm dhau los ua qhov tseem ceeb rau kev sib koom ua ke relays.
► Environmental Condition Handling
Relays yuav tsum tau tiv taus qhov kub thiab txias, yuav tsum muaj kev sib khi tsim. Thaum xaiv cov relays, peb yuav tsum ua tib zoo xav txog ntau yam ib puag ncig uas lawv yuav ntsib, xws li qhov kub thiab txias, qhov kub thiab txias. Qhov kub thiab txias ib puag ncig, tshwj xeeb tshaj yog, tuaj yeem ua rau kev laus relay; xaiv lub kaw tsim muaj peev xwm tiv thaiv nws cov kev ua tau zoo stability.
