Kurwanya kutabogama (NGRs) bigira uruhare runini muri sisitemu y'amashanyarazi, cyane cyane mukuzamura umutekano no kwizerwa mugihe habaye amakosa. Mugabanye imiyoboro yamakosa, ibyo bice birinda ibikoresho nabakozi ingaruka zishobora guterwa namashanyarazi. Iyi ngingo irasobanura imikorere, inyungu, hamwe nuburyo bukoreshwa mukurwanya kutagira aho bibogamiye, byerekana akamaro kabo mukubungabunga umutekano wamashanyarazi.
Niki aKutagira aho ubogamiye?
Kurwanya kutagira aho bibogamiye ni igikoresho cyamashanyarazi gihuza ingingo itabogamye ya transformateur cyangwa generator nubutaka. Intego yacyo yibanze ni ukugabanya imiyoboro inyura kumurongo utabogamye mugihe cyubutaka. Mugutangiza uburyo bwo guhangana ninzira nyabagendwa, NGRs yemeza ko inzira zamakosa zibikwa kurwego rushobora gucungwa, bityo bikarinda kwangirika kwibikoresho no kugabanya ingaruka z'umutekano.
Kurwanya kutabogama
Nigute Resistor idafite aho ibogamiye ikora?
Imikorere ya NGR ishingiye ku mategeko ya Ohm, ivuga ko ikigezweho (I) kingana na voltage (V) igabanijwe no guhangana (R) (I = VRI = RV). Mubihe bisanzwe byimikorere, ntagitemba kinyura muri NGR kuko nta tandukaniro rishobora kuba hagati yumwanya utabogamye nubutaka. Ariko, mugihe cyamakosa yubutaka - mugihe habaye isano itateganijwe hagati yumuriro wamashanyarazi nubutaka - hashobora kubaho itandukaniro rishobora gutuma umuyoboro utemba. Muri iki gihe, NGR igabanya ikosa ryikosa ritanga imbaraga zo kurwanya. Iki gikorwa kigabanya ubunini bwumuyaga unyura muri sisitemu, ukirinda kugera ku rwego rushimishije rushobora guteza ibikoresho byangiza cyangwa bigahungabanya umutekano nk’amashanyarazi cyangwa umuriro. NGR ikwirakwiza ingufu mugihe habaye ikosa mugihe ubushyuhe buguma mumipaka itekanye.
Inyungu zaAbadafite aho babogamiye
1.Kurinda ibikoresho: Mugabanye imiyoboro yamakosa, NGRs ifasha kurinda transformateur, generator, nibindi bikoresho bikomeye byamashanyarazi kwangirika mugihe cyamakosa yubutaka. Uku kurinda kurashobora kugabanya cyane amafaranga yo gusana nigihe cyo gutaha.
2.Umutekano wongerewe: NGRs igabanya ingaruka ziterwa na arc flash flash nibibazo byamashanyarazi mugucunga amakosa. Iyi ngingo ni ingenzi cyane cyane mubikorwa byinganda aho umutekano wabakozi wambere.
3.Guhindura icyiciro cya voltage: Mugihe cyibibazo, NGRs ifasha guhagarika voltage yicyiciro muri sisitemu. Uku gutezimbere kwemeza ko ibikoresho bihujwe bikora neza bitarinze guhindagurika kwa voltage bishobora gutera kunanirwa.
4.Korohereza Kumenya Amakosa: Mugabanye imigendekere yamakosa kurwego rwumutekano, NGRs itanga ibyuma birinda no kugenzura ibikoresho kugirango bikore neza. Ubu bushobozi bufasha mugushakisha vuba no gutandukanya amakosa, kugabanya sisitemu yo hasi.
5.Gukomeza ibikorwa: Rimwe na rimwe, NGR yemerera gukomeza gukora by'agateganyo mugihe kimwe kumurongo umwe. Iyi ngingo ni ingenzi cyane mu gukomeza serivisi mu bikorwa bikomeye nk'ibigo byita ku bigo nderabuzima.
Porogaramu Zidafite aho zibogamiye
Kurwanya kutagira aho bibogamiye bikoreshwa muri sisitemu zitandukanye z'amashanyarazi, harimo:
1.Sisitemu yo gukwirakwiza amashanyarazi make: Biboneka mu nganda n’inyubako z’ubucuruzi, NGR ni ngombwa mu kurinda imiyoboro y’amashanyarazi make ku makosa y’ubutaka.
2.Sisitemu yo gukwirakwiza hagati ya voltage.
3.Amashanyarazi adafite aho abogamiye: Amashanyarazi ahujwe na sisitemu yihariye akoresha NGR kugirango akumire amakosa arenze urugero mugihe cyubutaka.
4.Impinduka zidafite aho zibogamiye:Abahindura muburyo bwa wye iboneza bungukirwa na NGRs kugirango birinde kwangiza imigezi.
5.Sisitemu y'ingufu zishobora kuvugururwa:Kwiyongera gukoreshwa mumashanyarazi akomoka kumirasire y'izuba hamwe nimirima yumuyaga, NGRs zitanga igitaka no kurinda amakosa mugukoresha ingufu zishobora kubaho.
Umwanzuro
Kurwanya kutabogamanibintu byingenzi muri sisitemu zamashanyarazi zigezweho, zitanga uburinzi bukomeye kurinda amakosa yubutaka mugihe uzamura umutekano muri rusange. Mu kugabanya imiyoboro yamakosa no guhagarika ingufu za voltage, NGRs igira uruhare runini mukurinda ibikoresho nabakozi mu nganda zitandukanye. Mugihe amashanyarazi akomeje kwiyongera, gusobanukirwa no gushyira mubikorwa kutabogama kubutaka bizakomeza kuba ingenzi kugirango habeho ubusugire bwumutekano n’umutekano mu miyoboro ikwirakwiza amashanyarazi.
