Coil Input Ceev faj
1. Rated voltage kom ntseeg tau relay. Thaum lub relay tseem tuaj yeem ua haujlwm yog tias lub coil voltage tshaj qhov kev khiav hauj lwm voltage, nws yuav ua haujlwm tsis zoo nyob rau hauv cov kev cuam tshuam muaj zog. Tshaj qhov siab tshaj qhov kev khiav hauj lwm voltage tuaj yeem ua rau coil rwb thaiv tsev degradation, inter-tig luv circuits, thiab burnout.
2. Lub relay coil tsis kam hloov los ntawm kwv yees li 0.4%℃vim qhov kub thiab txias ntawm qhov sib txawv thiab cov relay nws tus kheej cua sov. Yog li ntawd, nce coil kub yuav nce ob qho tib si kev khiav hauj lwm thiab tawg voltages.
3. Automotive relays yog roj teeb -powered. Cov loads siab tuaj yeem ua rau poob qis hauv lub zog hluav taws xob, cuam tshuam rau relay lifespan. Ua tib zoo saib xyuas qhov cuam tshuam ntawm cov khoom siv hluav taws xob hluav taws xob hloov pauv ntawm kev cia siab rau relay.
4. Qhov siab tshaj plaws Nruam Chev Voltage: Dhau li ntawm kev ruaj ntseg relay, qhov siab tshaj plaws txuas txuas hluav taws xob feem ntau yog txwv los ntawm kev ua haujlwm rwb thaiv tsev ntawm cov hlau enameled. Cov chav kawm rwb thaiv tsev ntawm enameled hlau yuav tsum to taub. Hauv kev siv tswv yim, rau Class F rwb thaiv tsev ntawm qhov kub thiab txias ntawm 40 degree, qhov kub nce tuaj yeem txwv rau qhov siab tshaj plaws ntawm 115℃raws li ntsuas los ntawm txoj kev ua haujlwm. Txawm li cas los xij, vim tias tsis yog -ib puag ncig ntawm cov coils sab hauv thiab sab nrauv, pom zoo kom muaj tus nqi ntawm 105 degree.
5. Coil Electrolytic Corrosion: Automotive relays ua haujlwm nyob rau hauv ib puag ncig uas hloov pauv kub thiab av noo rau lub sijhawm ntev. Thaum lub kauj txuas txuas mus txuas ntxiv mus rau qhov zoo ntawm cov khoom siv hluav taws xob (nrog rau lub davhlau ya nyob twg tsis zoo), electrolytic corrosion tuaj yeem tshwm sim, ua rau cov hlau tawg. Yog li ntawd, lub relay coil yuav tsum tsis txhob txuas nrog lub peev xwm siab; lub relay coil thiab txav reed yuav tsum tau txiav tawm ntawm qhov zoo kawg nkaus ntawm lub hwj chim mov.
Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv: Cov kev tiv tauj yog cov khoom tseem ceeb tshaj plaws ntawm lub relay. Lawv txoj kev ntseeg tau cuam tshuam los ntawm cov khoom siv sib cuag, tiv tauj qhov hluav taws xob thiab tam sim no (tshwj xeeb tshaj yog qhov hloov hluav taws xob thiab cov nthwv dej tam sim no), hom thauj khoom, hloov pauv, thiab ib puag ncig. Tiv tauj Voltage: Inductive loads ua kom muaj zog rov qab siab heev. Cov hluav taws xob ntau dua ua rau muaj zog ntau dua, ua rau kev sib cuag electrolytic corrosion thiab hlau hloov mus. Yuav tsum tau ceev faj. Hu rau tam sim no: Tam sim no thaum lub sijhawm kaw thiab qhib kev cuam tshuam cuam tshuam rau kev sib cuag. Thaum lub load yog lub cev muaj zog los yog lub teeb taub hau, lub inrush tam sim no thaum lub sij hawm kaw yog loj, ua rau ntau dua kev sib cuag hnav thiab hlau hloov. Kev sib tiv tauj tuaj yeem ua rau kev sib cuag tsis ua haujlwm; kev kuaj xyuas yuav tsum tau ua.
Tiv tauj tiv thaiv Reverse Voltage: Thaum disconnecting ib relay coil series Circuit Court los yog inductive loads xws li motors thiab electromagnets, surge absorption siv diodes los yog zoo xws li cov khoom yuav tsum tau ua hauj lwm los tiv thaiv cov neeg. Disconnecting ib inductive load generates ib tug rov qab voltage ntawm pua pua mus rau phav phav volts, exacerbating tiv thaiv corrosion thiab txo kev sib cuag lifespan. Tsis tas li ntawd, thaum lub inductive load tam sim no tsawg dua 1A, lub arc generated los ntawm qhov rov qab voltage decomposes cov organic gases volatilized los ntawm relay lub internal coil thiab yas, tsim dub oxides thiab carbon deposits ntawm cov neeg, ua rau cov neeg pluag kev sib cuag. Hu rau Hlau Hloov: Kev sib cuag hlau yog kev hloov pauv ntawm cov khoom sib cuag hauv qab DC tam sim no. Nrog rau kev hloov pauv ntau zaus, cov pits tsim ntawm cov neeg sib cuag anode thiab bulges ntawm cov kab mob cathode. Cov bulges thiab pits no tuaj yeem yooj yim ua rau lub tshuab xauv, ua rau kev sib cuag adhesion. Anti-Hloov cov ntaub ntawv tiv tauj lossis tiv thaiv Circuit Court yuav tsum raug xaiv. Tiv tauj Tiv Thaiv Absorption Circuit Court: Siv cov khoom tiv thaiv tiv thaiv lossis circuits tuaj yeem txo qhov hluav taws xob rov qab, tab sis kev siv tsis raug tuaj yeem muaj qhov tsis zoo.
Kev Tiv Thaiv Kev Siv Relay
1. Txhawm rau tiv thaiv kev kis kab mob ntawm cov hlau lead, tsis txhob tiv tauj ncaj qha; txwv tsis pub, solderability yuav txo.
2. Cov haujlwm ua cov hlau lead yuav tsum sib haum nrog lub qhov ntawm lub rooj tsav xwm luam tawm. Ib qho tsis tsim nyog yuav ua rau muaj kev ntxhov siab txaus ntshai ntawm lub relay, ua rau nws qhov kev ua tau zoo thiab kev ntseeg siab. Thov xa mus rau daim duab kos duab hauv cov qauv rau drilling.
3. Tom qab muab cov relay tso rau hauv lub rooj tsav xwm hauv Circuit Court, tsis txhob khoov cov hlau lead kom tsis txhob cuam tshuam cov relay lub sealing los yog lwm yam kev ua tau zoo.
4. Tsis txhob siv lub zog ntau dhau rau lub relay vaj tsev thaum lub sij hawm tso kom tsis txhob muaj vaj tse tawg lossis hloov pauv ntawm kev ua haujlwm.
5. Lub zog ntxig thiab tshem tawm rau qhov ceev - txuas pins yog 10 kgf. Kev ntxig thiab tshem tawm ntau dhau yuav ua rau lub cev puas tsuaj; Lub siab tsis txaus yuav cuam tshuam rau kev ntseeg tau ntawm kev sib cuag thiab lub peev xwm nqa tam sim no.
6. Nws yog ib qho tseem ceeb tshwj xeeb uas yuav tsum tau hais tias yog hais tias tus relay raug poob los yog cuam tshuam thaum lub sij hawm installation, txawm hais tias cov hluav taws xob tsis muaj nyob rau hauv qhov kev txwv, nws cov neeg kho tshuab tsis muaj peev xwm hloov tau, ua rau muaj kev phom sij loj. Xws li relays yuav tsum tau zam yog tias ua tau.
7. Tsis txhob siv silicone- muaj cov resins thiab preservatives, vim lawv tuaj yeem ua rau kev sib cuag tsis ua haujlwm, txawm tias nyob rau hauv molded relays.
8. Xyuas kom lub coil thiab cov khoom siv hluav taws xob tiv tauj txuas nrog raws li qhov polarity teev. Feem ntau, lub caij nplooj ntoos hlav txav mus rau qhov zoo (+) lub davhlau ya nyob twg.
9. Tsis txhob siv qhov hluav taws xob mus rau lub kauj hluav taws xob tshaj qhov siab tshaj qhov tso cai hluav taws xob lossis ua rau lub coil kub nce siab tshaj qhov rwb thaiv tsev ntawm cov hlau enameled.
10. Rated load thiab lifespan yog nyob rau hauv cov txheej txheem txheej txheem thiab tsis tuaj yeem npog tag nrho cov kev cai siv ntawm tsheb relays. Kev tiv tauj tiag tiag thiab kev ua neej nyob tuaj yeem sib txawv vim yog hom kev thauj khoom, ib puag ncig, kev ua haujlwm zaus, thiab lwm yam.
