Ama-varistors aphezulu athola amandla ezimbonini ezahlukahlukene ngenxa yekhono lawo lokuvikela izinto zikagesi ekukhuphukeni kwamandla kagesi kanye nezimo zokudlula ngokweqile kwesikhashana.Lezi zingxenye ezithuthukisiwe ziya ngokuya zisetshenziswa ezinhlelweni zezimboni ukuvikela okokusebenza okubucayi nokuqinisekisa ukusebenza okungaphazamiseki.
Emkhakheni wezimoto, ama-varistors anamandla aphezulu ahlanganiswa kumayunithi okulawula ama-elekthronikhi (ama-ECU) namasistimu okusabalalisa amandla ukuze avikeleke ekuphakameni kwamandla kagesi okubangelwa umbani, ukuphazamiseka kukazibuthe, nokunye ukuphazamiseka kukagesi.Lokhu kusiza ukuthuthukisa ukuthembeka nokuhlala isikhathi eside kwe-elekthronikhi ebalulekile yezimoto, ekugcineni kuthuthukiswe ukuphepha nokusebenza kwemoto.
Ngaphezu kwalokho, ukuthunyelwa kwezinhlobonhlobo zamandla aphezulu emkhakheni wamandla avuselelekayo sekubalulekile ekuvikeleni iziguquli zelanga, izinjini zomoya, nezinye izisetshenziswa zokuphehla ugesi ekuguquguqukeni kukagesi kanye nokwenyuka okubangelwa umbani.Ngokuhlinzeka ngokuvikeleka okuqinile kokugcwala kwe-voltage, lawa ma-varistors afaka isandla ekuzinzeni nasekusebenzeni kahle kwezinhlelo zamandla avuselelekayo, ngaleyo ndlela asekele inguquko eya ekuphehleni ugesi esimeme.
Embonini yezokuxhumana, ama-varistors aphezulu adlala indima ebalulekile ekuvikeleni ingqalasizinda yenethiwekhi ebucayi, njengeziteshi eziyisisekelo, izinti, nezinto zokuxhumana, kusuka kuma-voltage adlulayo angabangelwa ukushaywa kombani noma ukuphazamiseka kwegridi yamandla.Lokhu kusiza ukugcina ukwethembeka nokuqina kwamanethiwekhi ezokuxhumana, ukuqinisekisa ukuxhumana okungaphazamiseki kwamabhizinisi nabathengi.
Ngaphezu kwalokho, umkhakha we-automation yezimboni usebenzisa ama-varistors aphezulu ukuze kuvikelwe izilawuli ze-logicable logic (PLCs), amadrayivu ezimoto, neminye imishini ebalulekile ekuqhumeni kwamandla kagesi, ngaleyo ndlela kuncishiswe ubungozi bokulimala kwemishini kanye nesikhathi sokuncipha sokukhiqiza.Lokhu kubaluleke kakhulu ezikhungweni zokukhiqiza lapho ukusebenza okungaphazamiseki kubalulekile ukuze kuhlangatshezwane nezinhloso zokukhiqiza nokugcina ukuncintisana.
Sekukonke, ukusetshenziswa kwe-varistors yamandla aphezulu ezimbonini ezahlukahlukene kugcizelela ukubaluleka kwazo ekuvikeleni izimpahla ze-elekthronikhi ezibalulekile kanye nokuqinisekisa ukwethembeka kwezinhlelo ezibalulekile.Njengoba ubuchwepheshe buqhubeka nokuthuthuka, isidingo salezi zingxenye zokuvikela okuthuthukile kulindeleke ukuthi sikhule, siqhubekisele phambili ukuqamba okusha nokuhlanganiswa kuyo yonke imikhakha yezimboni eyahlukene.
