Nibihe bintu byingenzi bigira ingaruka ku guhitamo insinga zanyuma?

Kugeza ubu, ikoreshwa ryoguhindura amashanyarazi mubicuruzwa bya elegitoronike byahindutse inzira yiterambere, kandi ibice byo guhinduranya amashanyarazi bigenda byiyongera buhoro buhoro, kandi birashobora gutwara imbaraga nini zisohoka.Hamwe no kwiyongera kwijwi rya terefone, ibikenewe byuruhare rwabo mumashini nibikoresho bigenda bigaragara cyane, kandi bigira uruhare runini mukwemeza ibiranga ibicuruzwa.Ibikurikira mubyukuri byerekana ibintu byingenzi byo gutoranya ibyuma byangiza.

Ubwa mbere, gusohora imbaraga zo gukemura ibintu

Kimwe mubintu byambere bigomba gusuzumwa nubushobozi bwibigize gukorana nimbaraga zisohoka.Nta bisobanuro bihari byo gusobanura imbaraga zisohoka nibiranga ibicuruzwa byanyuma.Ibisobanuro hamwe na moderi ya bisi ya terefone ikorerwa mu Burayi ni ibipimo bya IEC, mu gihe ibyakozwe muri Amerika ari ibipimo bya UL.

Itandukaniro riri hagati yuburyo bubiri ni rinini.Ba injeniyeri ba tekinike badasobanukiwe nuburyo bwibicuruzwa bakoresha ibyago byinshi cyane byo gukoresha ibice bitagera kurwego rusabwa rwo gusohora ingufu, cyangwa gukoresha ibice bifite ibisobanuro birenze kure ibisabwa.Mu Burayi, igipimo kiriho kigenwa nubushyuhe bwumuyoboro wicyuma ugaragaramo icyerekezo.Iyo ubushyuhe bwicyuma pin burenze 45 ℃ kurenza ubushyuhe bukora, abakozi bapima neza bazakoresha uyu muyoboro nkigiciro cyagenwe cyagenwe (cyangwa umuyaga mwinshi) wibigize.Ikindi kintu mubisobanuro bya IEC nibishobora kwemerwa, ni 80% byinini nini.Ibinyuranyo, ibisobanuro bya UL bishyiraho amafaranga agezweho kubigize nka 90% byubu mugihe ubushyuhe bwumuyoboro wicyuma burenze ubushyuhe bwimikorere ya 30 ℃.Ntabwo bigoye kubona ko ubushyuhe bwigice cyumuyagankuba wamashanyarazi yibikoresho byicyuma nikintu gikomeye cyane mubisabwa byose.Ibi nibyingenzi mubikoresho bya mashini.Kuberako ibikoresho bya mashini bigomba kuba mubushyuhe bwa 80 ℃ ibidukikije bikora.Niba ubushyuhe bwa terminal ari 30 ℃ cyangwa 45 ℃ hejuru yubushyuhe, ubushyuhe bwanyuma bushobora kurenga 100 ℃.Bitewe n'ubwoko bw'amafaranga n'ibikoresho byo gutoranya byatoranijwe kubice byatoranijwe, ibicuruzwa bigomba gukoreshwa mugihe kiri munsi yumuvuduko wagenwe kugirango bishobore gukoreshwa neza mubipimo byubushyuhe bwifuzwa.Rimwe na rimwe, ibikoresho fatizo bikwiranye nibikoresho bipfunyitse ntibishobora kubara neza ibisabwa byo gukuraho ubushyuhe neza, bityo rero ibice byibi bikoresho bigomba kuba bike cyane ugereranije nu byateganijwe.
