Automotive relays yog relays siv nyob rau hauv tsheb. Cov relays hloov siab load zog thiab muaj kev poob siab thiab kev co kuj.
Cov khoom siv hluav taws xob hauv tsheb feem ntau yog 12V, thiab cov coil voltage feem ntau yog tsim los ua 12V. Vim lub roj teeb fais fab mov thiab voltage instability; hnyav ib puag ncig; thiab qhov tsawg kawg nkaus rub-hauv qhov hluav taws xob (V Tsawg dua lossis sib npaug rau 60% VH, ntsuas kev ua haujlwm voltage); coil overvoltage tso cai kom ncav cuag 1.5VH. Coil fais fab noj yog qhov siab, feem ntau 1.6-2W, ua rau kub siab. Environmental yuav tsum tau nruj heev: nyob rau hauv lub engine compartment, lub ambient kub yog -40℃mus rau 125 degree; Hauv lwm qhov chaw, qhov ntau yog -40℃txog 85 degree. Relays siv nyob rau hauv lub cav compartment yuav tsum tiv thaiv xuab zeb, dej, ntsev, thiab roj; vibration thiab poob siab kuj tseem xav tau heev.
Ib tug tswj relay muaj ob lub ntsiab: ib tug tswj system thiab ib tug tswj system. Yog vim li cas vim li cas kev tswj hwm relays tuaj yeem ua lub luag haujlwm tswj yog tias thaum muaj qee lub teeb liab, xws li hluav taws xob, sib nqus, thermal, lossis optical lub cev muaj nuj nqis, nkag mus rau hauv nws cov kev tswj hwm thiab nce mus txog ib qho nqi, qhov kev tswj kom muaj nuj nqis ntawm cov tswj (tseem hu ua cov zis hluav taws xob) tuaj yeem hloov pauv sai li ntawm xoom mus rau ib qho nqi, lossis los ntawm qee qhov txiaj ntsig xws li kev tiv thaiv, kev ua haujlwm ntawm xoom, muaj nuj nqi thiab kev hloov pauv. cov ntaub ntawv. Cov yam ntxwv ntawm kev tswj relays yog tias lawv tuaj yeem tswj tau qhov tam sim no loj nrog lub me me tam sim no.
