Ohlelweni lokuvikelwa kwemishini ye-elekthronikhi, izinhlobonhlobo zidlala indima ebalulekile, zinikeza ukuvikela lapho umjikelezo ehlangana nezimo ezivelele.Kodwa-ke, njenganoma iyiphi enye ingxenye ye-elektroniki, i-varistor ingaba nomonakalo othinta ukusebenza okufanele kwesifunda sonke.Lo mbhalo uhlose ukudela izindlela zokutholwa komonakalo we-varistor ukuze izinkinga zitholwe ngokushesha nezindlela zokulungisa ezihambelana nazo zingathathwa.
1. Ukukhonjwa kwe-varistor eyonakele
I-Varitortor, njengengxenye ebalulekile yokuvikelwa komkhawulo, idlala indima ebalulekile emishini ye-elekthronikhi.Yize bengekho ukuthi bahlukunyezwa ukulimala njengezinye izinto, uma kukhona okungahambi kahle, imiphumela ingaba sína.Ukulimala kwe-varistor kuvame ukuzibonakalisa njengomjikelezo ovulekile, ngezikhathi ezithile kukhuphuka ngokumelana, ngenkathi kuncipha ekumelaneni nakho akuvamile.Kunezinhlobo eziningi zokumelana, kufaka phakathi abamelana namafilimu e-carbon, abamelana nemephu yensimbi, ukumelana nokuwayipha, kanye nokusakazwa kwe-fuse.Izinhlobo ezahlukene zokumelana zinezimpawu zokubukeka ezihlukile ngemuva komonakalo.Isibonelo, ukumelana namanxeba e-wire kungavela mnyama noma kube nemifantu engaphezulu, kanti ukumelana nosimende kungahle kwehle lapho kushiswe.Ngaphezu kwalokho, lapho ukumelana kwe-fuse kulimele, ingaphezulu laso lingahle lilimele, kepha ngeke lishiswe noma libe mnyama.
2. Ukulungiselela ngaphambi kokuhlolwa
Ngaphambi kokuhlola i-varistor, kufanele kwenziwe amalungiselelo anele.Okokuqala, kudingeka uqinisekise ukuthi ukuhlolwa kuholela kwi-multimeter kanye nezikhonkwane kuwo womabili amaphethelo omhlaba axhumeke kahle.Asikho isidingo sokuhlukanisa phakathi kokuhle nokubi kule nqubo.Ukuze uthuthukise ukunemba kokukalwa, uhla olufanele kufanele lukhethwe ngokususelwa kunani lokumelana lokumelana kukalwa.Lesi sinyathelo sibalulekile kwinqubo yokuhlola elandelayo, ngoba ukukhetha okulungile okungaqinisekisa ukunemba kwemiphumela yokuhlola.
3. Inqubo enemininingwane yokuhlola
Inqubo yokutholwa yeVaristor ingahlukaniswa izinyathelo eziningana.Okokuqala, setha ifindo le-multimeter legiya endaweni yokumelana nesikhashana esifushane ipeni lokuhlola.Ngalesi sikhathi, kufanele ubone ukuthi isikhombi se-multimeter sikhomba ku-zero.Uma kungenjalo, udinga ukulungisa i-Ohm zero-elungisa ama-potentiometer kuze kube yilapho isikhombi sihambisana ne-zero.Okulandelayo, khetha indawo efanelekile yokukhulisa ngokususelwa ekumelaneni komphikisi olinganiswe.Lesi sinyathelo sibalulekile ngoba ukunemba kokufunda kwe-multimeter kuthinteka ngqo ekukhetheni kokukhulisa.Ekugcineni, ngemuva kokushintshwa ngakunye kwamagiya wokukhulisa, ukusebenza kokulungiswa kwe-zero yegiya lokumelana kumele kwenziwe futhi ukuze kuqinisekiswe ukunemba kwesilinganiso ngasinye.
