Isivikelo sokuhlinza esignali iwuhlobo lwesivikeli sokuhlinza, esisho idivayisi yokuvikela umbani exhunywe ochungechungeni emugqeni wesignali ukuze kukhawulwe ukugcwala ngokweqile kwesikhashana kanye nokukhipha amandla amanje emugqeni wesignali. Emphakathini wanamuhla lapho amathuluzi e-microelectronic asetshenziswa kakhulu, abavikeli besignali babaluleke kakhulu ekuvikelekeni kombani kwamasistimu kagesi. Isidingo sabavikeli bezimpawu zokuhlinza sizochazwa ngokuningiliziwe namuhla. 1. Izingxenye ezingaqondile zesivikeli sokuhlinza kwesignali Imisebenzi emibili ebalulekile yesivikeli sokuhlinza isignali ukukhulula umbani wamanje kanye nomkhawulo we-voltage yokuqhuma igcwaliswa yizingxenye ezingezona umugqa kusivikeli sokuhlinzwa kwesignali. Izakhi ezingezona umugqa kusivikeli sokuhlinza isignali zingabaphikisi abangaqondile kanye nezinto ezishintshayo. Ngokuvamile ibhekisela ku-varistor. Isebenza ngesimiso sokuthi i-resistor engaqondile ixhunywe phakathi komugqa nomhlabathi, ngokuvamile kubhekwa njengesifunda esifushane. Lapho i-overvoltage kwenzeka ohlelweni lwe-elekthronikhi, faka i-overcurrent edlulayo ngaphesheya kwesistimu ingamelana nomhlabathi, inciphise ukugcwala komugqa noma imishini, futhi uqinisekise ukuphepha komugqa wesiginali kanye nemishini. Inethiwekhi yesivikeli sokukhuphuka okubili kokukodwa 2. Ukuhlelwa kwezivikeli zokukhuphuka kwesignali Ngokuya ngezinhlobo ezahlukene zemigqa yokuvikela, abavikeli besignali bangase bahlukaniswe babe abavikeli besignali yenethiwekhi, abavikeli besignali abaqaphayo, izivikeli zokukhuphuka kwesignali, izivikeli zokukhuphuka kwesignali yevidiyo, izivikeli zokuhlinza zesignali yocingo, isivikelo sokuqhunyiswa kwesignali esingaqhumi, njll. Ngamunye. uhlobo lunamamodeli ahlukahlukene, imingcele nokubukeka okuhlukile. Ividiyo yokuvikela okubili kokukodwa kokuthathu, indima yesivikeli sokuhlinzwa kwesignali Isivikeli sokukhuphuka kwesignali sigcina ngokuyinhloko ukuphepha kombani komugqa wesignali nezinto zokusebenza. Imisebenzi yayo eyinhloko yilezi: Okokuqala, i-overvoltage yesikhashana ebangelwa umbani obangelwa umugqa wesignali inomkhawulo. Ngokwezibalo, ngaphezu kuka-80% wokushaywa kombani ezinhlelweni zikagesi kubangelwa umbani ongeniswayo. Ngakho-ke, emphakathini wanamuhla, ukusetshenziswa okubanzi kwemishini ye-microelectronic kufanele kuqinise ukuvikeleka kombani obangelwa uhlelo lwe-elekthronikhi, futhi kufake isivikeli esifanelekile sokuhlinza isignali. Ividiyo 3 ku-1 umvikeli wokuhlinzwa Okwesibili ukukhawulela ukukhuphuka okubangelwa ukuqala nokuma kohlelo lwe-elekthronikhi. Ngaphezu kokuhlinzwa okubangelwa ukungeniswa kombani, isizathu esibaluleke kakhulu sokwanda komugqa wesignali ukuqala nokumiswa kwemikhiqizo ye-elekthronikhi. Ukukhuphuka okunjalo nakho kuvamile. Ukufaka isivikelo sokuhlinza isignali esifanele kulayini kungacindezela ngempumelelo ukuqubuka okubangelwa ukusebenza kohlelo lwe-elekthronikhi, kunciphise ngempumelelo izinguquko nokwehluleka kwemishini ebucayi kagesi, kuqinisekise ukuzinza komugqa wesiginali, futhi kuthuthukise impilo yesevisi yemikhiqizo kagesi. .
