Ubushinwa Bwiza Bumurika Bisi Bar
Bisi ya bisi yamenetse, nanone yitwa bisi ya bisi, laminated no-inductance bisi, bisi ya bisi ya inductance, bisi ya bisi ya elegitoronike, nibindi.Bisi ya baminine igizwe nibintu byinshi bitwara ibintu hamwe nibikoresho byo kubika.
Bisi ya baminine ni umuhanda wa sisitemu yo gukwirakwiza amashanyarazi.Ugereranije nuburyo bwa gakondo buremereye kandi buvurunganye, bufite ibiranga nka impedance nkeya, kurwanya-kwivanga, kwizerwa kwiza, kuzigama umwanya no guterana byihuse.Ikoreshwa cyane muri transit ya gari ya moshi, umuyaga nizuba, inverteri yinganda, sisitemu nini ya UPS cyangwa ibindi bice bisaba gukwirakwiza amashanyarazi.
Kubikoresho byacu byo kubyaza umusaruro, nyamuneka sura ibikoresho byacu (https://www.scdfelectric.com/copper-aluminum-bus-bars/).
Utubari twa bisi ya laminated ni twenyine dushingiye ku bishushanyo by'abakoresha n'ibisabwa tekinike.Ba injeniyeri bacu bose mumatsinda ya tekinike bafite uburambe bwimyaka irenga icumi yo guteza imbere no gukora bisi ya baminine, barashobora gufasha abayikoresha kunoza imiterere yibicuruzwa kandi bizeye ko bazaguha ibicuruzwa byiza kandi byiza kuri wewe.
Ibiranga ibicuruzwa
1) Coefficient ya inductance nkeya, imiterere yoroheje, ikiza neza umwanya wimbere wimbere, kongera ahantu hasaranganya ubushyuhe, kandi igenzura neza izamuka ryubushyuhe bwa sisitemu.
2) Impedance ntarengwa igabanya gutakaza umurongo kandi itezimbere cyane ubushobozi bwo gutwara ibintu hejuru yumurongo.
3) Irashobora kugabanya ibyangiritse kubice biterwa no kugabanuka kwa voltage no kongera igihe cyumurimo wibikoresho bya elegitoroniki.
4) Kugabanya urusaku rwa sisitemu na EMI, kwivanga kwa RF.
5) Imbaraga zikomeye modular ihuza ibice bigize hamwe byoroshye kandi byihuta.
Ibyiza bya Bus ya Laminated
1) Inductance yo hasi
Utubari twa bisi zometseho ni ibice bibiri cyangwa byinshi byerekana ibyapa bikozwe mu muringa bishyizwe hamwe, ibyapa bya plaque y'umuringa byashyizwe mu mashanyarazi n'ibikoresho byo kubika, kandi ibice bitwara imashanyarazi hamwe n’ibice byiziritse byashyizwe mu buryo bwuzuye binyuze mu nzira yo gutwika amashyuza.
Umugozi uhuza wakozwe mubice byambukiranya ibice, byongera ubuso bwurwego rwimiyoboro munsi yumurongo umwe wubu, kandi mugihe kimwe, intera iri hagati yimyitwarire iragabanuka cyane.Bitewe ningaruka zegeranye, ibice byegeranye byegeranye bitemba bihabanye ningaruka, kandi bitanga umusaruro Imirima ya magneti ihagarika undi, kuburyo inductance yagabanijwe mumuzunguruko igabanuka cyane.Muri icyo gihe, kubera imiterere yacyo igaragara, ahantu hagabanijwe ubushyuhe bwiyongereye cyane, bifasha kongera ubushobozi bwacyo bwo gutwara.
1) Imiterere
Imiterere yuzuye, gukoresha neza umwanya no kugenzura neza ubushyuhe bwa sisitemu.
Mugabanye umubare wibigize kandi wongere ubwizerwe bwa sisitemu.
Biroroshye gushiraho no kubungabunga.
Biroroshye kandi byiza.
