Yintoni Ukhuseleko Lokunyuka Kombane?

Iinkqubo zombane namhlanje zinobuthathaka ngakumbi kunangaphambili. Ndihlala ndibona izixhobo zigxile kumthamo kunye nokusebenza kakuhle, ngelixa iingozi zexesha elifutshane zombane zithathwa kancinci de kubekho ukungasebenzi kakuhle.

Ukhuseleko lokuqubha ibhekisa kwiindlela zobunjineli kunye nezixhobo ezisetyenziselwa ukulawula ukugqithisa kwamandla ombane okwethutyana kunye nokuthintela umonakalo kwizixhobo zombane neze-elektroniki. Kwizakhiwo zoshishino kunye nezorhwebo, ukhuseleko lokunyuka kombane luyinxalenye ephambili yokuthembeka kwenkqubo, ukhuseleko, kunye nolawulo lweendleko zomjikelo wobomi.

Njengoko izixhobo ze-elektroniki zamandla, ezenzekelayo, kunye neenkqubo zolawulo lwedijithali ziba zizinto eziqhelekileyo, ukuqonda indlela ukhuseleko lokuhamba olusebenza ngayo—kunye nendlela yokuludibanisa ngokuchanekileyo—kuye kwaba yinto ebalulekileyo kwiinjineli kunye nabenzi bezigqibo.

Izisombululo zoKhuselo loKhuseleko zinciphisa njani iingozi zokugqithisa amandla?

Izisombululo zokukhusela umbane zinciphisa iingozi zombane ogqithisileyo ngokuphambukisa amandla ombane ogqithisileyo kude nezixhobo ezibuthathaka kwaye ziwakhuphele emhlabeni ngokukhuselekileyo kwimizuzwana emincinci.

Indlela yoKhuselo loMbane oPhezulu

A isixhobo sokukhusela ukugaleleka isebenza ngokutshintshela kwisimo sokuthintela okuphezulu ukuya kwindlela yokuthintela okuphantsi xa kuvela ukunyuka okukhulu. Le mpendulo ikhawulezayo ibamba i-voltage ukuya kwinqanaba lokukhusela elichazwe kwangaphambili, ithintela ukuba ingadluli kwimida yokukhusela izixhobo.

Ubuchwepheshe obuphambili obusetyenziswa kwizixhobo zokukhusela ukugquma buquka:

• Ii-Metal Oxide Varistors (ii-MOV)

• Iityhubhu zokukhupha igesi (iiGDT)

• Iidiode zeTransient Voltage Suppression (TVS)

Itekhnoloji nganye isebenza indima ethile ngokuxhomekeke kubukhulu bokunyuka kwamandla, isantya sempendulo, kunye nombane wenkqubo.

Ukulawula Amandla Okunyuka kunye neVolthi eseleyo

Iyasebenza ukhuseleko lokunyuka kombane Ayipheleli nje ekufunxeni umsinga womoya ohamba ngamandla. Ikwagxila ekunciphiseni i-residual voltage—i-voltage ehlala kwiiterminal zezixhobo emva kokuba i-surge ijikelezisiwe.

Ukuba i-voltage eseleyo idlula ukunyamezela izixhobo, umonakalo usenokuvela nokuba kufakwe i-surge protector. Yiyo loo nto izixhobo zokukhusela i-surge kufuneka zilinganiswe ngokuchanekileyo kwaye zilungelelaniswe ngaphakathi kwenkqubo.

Kutheni uKhuselo lokuKhupha luyiNqanaba lokuthintela

Ukunyuka okwethutyana kusenokungabangeli ukungaphumeleli ngoko nangoko. Endaweni yoko, kudla ngokuphumela kwezi zinto zilandelayo:
