Gusobanukirwa Mcb Circuit Breakers: Ubuyobozi bwuzuye
Mu isi y’ubuhanga mu by’amashanyarazi n’umutekano, utumashini duto dukoresha amashanyarazi (MCB) tugira uruhare runini mu kurinda imiyoboro y’amashanyarazi imitwaro myinshi n’imiyoboro migufi. Ibi bikoresho ni ingenzi ku miyoboro y’amashanyarazi yo mu ngo no mu bucuruzi, birinda ibikoresho n’insinga kwangirika guterwa n’umuyoboro w’amashanyarazi mwinshi.
Ikinyabiziga cya Mcb ni iki?
Umukingo wa MCB ni umukingo wikora uhagarika urujya n'uruza rw'amashanyarazi mu mukingo iyo ubonye ikibazo kidasanzwe, nko gusinda cyangwa umukingo mugufi. Bitandukanye na za fuse zisanzwe, zigomba gusimburwa nyuma yo gushya, umukingo wa MCB ushobora kongera gusubizwa inyuma nyuma yo gushwanyagurika, bigatuma uba amahitamo yoroshye kandi meza yo kurinda umukingo.
Imashini igabanya urujya n'uruza rwa Mcb ikora ite?
Imikorere ya Mcb circuit breakers ishingiye ku buryo bubiri bw'ingenzi: ubushyuhe n'ubukuru.
1. Uburyo bwo gushyushya:Iki gice gisubiza mu bihe by’umuvuduko mwinshi. Iyo umuyoboro w’amashanyarazi unyura mu muyoboro urenze ubushobozi bw’umuyoboro w’amashanyarazi, ubushyuhe butangwa butuma umuyoboro w’amashanyarazi w’amashanyarazi uri mu muyoboro w’amashanyarazi ugonda. Iyo umuyoboro w’amashanyarazi ugeze ku rwego runaka, umuyoboro w’amashanyarazi w’amashanyarazi utangira gukora uburyo bwo gufunga umuyoboro w’amashanyarazi, ugafunga umuyoboro w’amashanyarazi.
2. Uburyo bwa rukuruzi: Ubu buryo bwagenewe gusubiza ku miyoboro migufi. Iyo habayeho umuyoboro mugufi, umuyoboro w'amashanyarazi wiyongera cyane, bigatuma imbaraga zikomeye za rukuruzi zikurura umugozi, bigatuma umuyoboro w'amashanyarazi ugwa hafi ako kanya. Ubu buryo bwihuse ni ingenzi mu gukumira kwangirika kw'ibice by'amashanyarazi no kugabanya ibyago by'inkongi y'umuriro.
Ubwoko bw'ikinyabiziga cya Mcb
Utwuma dukoresha imiyoboro ya Mcb tuboneka mu bwoko butandukanye, buri kimwe cyagenewe intego runaka:
Ubwoko B: Ku bijyanye n'ibikoresho byo mu rugo, ubu bwoko bw'amashanyarazi agabanya umuvuduko w'amashanyarazi bugenda inshuro 3 kugeza kuri 5 z'umuvuduko w'amashanyarazi. Bukwiriye cyane ku bikoresho bifite imitwaro irinda umuvuduko, nk'amatara n'ubushyuhe.
Ubwoko C: Ubwo bwoko bwagenewe gukoreshwa mu bucuruzi n'inganda, bufite umuvuduko w'amashanyarazi ukubye inshuro 5 kugeza ku 10 umuvuduko w'amashanyarazi. Bukwiriye imiyoboro ifite imizigo ikoreshwa mu gukurura, nka moteri na transfoma.
Ubwoko D: Ubwo bwoko bukoreshwa mu bikorwa bifite umuvuduko mwinshi w’amashanyarazi, nka moteri nini na transfoma. Igwa inshuro 10 kugeza kuri 20 z’umuvuduko w’amashanyarazi.
Ibyiza byo gukoresha Mcb circuit breakers
1. Umutekano: Utwuma dukoresha amashanyarazi twa Mcb dutanga uburyo bwizewe bwo kurinda ibyuma biremereye cyane n'uduce duto, bigabanya cyane ibyago by'inkongi z'umuriro n'ibyangiritse by'ibikoresho.
2. Uburyo bworoshye bwo gukoraBitandukanye na za fuse zigomba gusimburwa nyuma yo guhumeka, Mcb circuit breakers zishobora kongera gukoreshwa byoroshye, ibyo bikaba byoroshye kuyikoresha.
3. Igishushanyo mbonera gito: Utwuma twa MCB duto kandi duto kurusha ibikoresho bisanzwe byo kurinda uruziga, bigatuma umwanya ukoreshwa neza mu byuma bikoresha amashanyarazi.
4. Ihendutse ku giciroNubwo ishoramari rya mbere rishobora kuba riri hejuru ugereranije na fuse, kuzigama igihe kirekire kugabanyije kwangirika kw'ibikoresho no koroshya kongera gukoresha ibikoresho bituma Mcb circuit breakers iba amahitamo meza kandi ahendutse.
Gushyiraho no kubungabunga
Gushyiraho icyuma gihagarika amashanyarazi bigomba gukorwa buri gihe n'umuhanga mu by'amashanyarazi kugira ngo habeho kubahiriza amategeko y'amashanyarazi yo mu gace utuyemo n'amahame y'umutekano. Nanone kandi, igenzura rihoraho ry'ibikorwa byo kubungabunga amashanyarazi rigomba gukorwa kugira ngo hamenyekane niba icyuma gihagarika amashanyarazi gikora neza kandi hamenyekane ibibazo bishobora kubaho mbere yuko biba bikomeye.
Ni irihe tandukaniro riri hagati ya MCB na MCCB breakers?
MCB: Muri rusange zikoreshwa mu bucuruzi n'inganda zifite voltage nkeya, ubusanzwe 120V, 240V cyangwa 480Y VAC, ndetse na VDC 1000. MCCB: Zishobora gukoreshwa haba mu zikoreshwa zifite voltage nkeya n'izifite voltage nyinshi, aho amanota asanzwe agera kuri 600V cyangwa 690V, ndetse na moderi zimwe na zimwe zihabwa amanota ku bijyanye na voltage nyinshi.
Muri make
Mu magambo make, imiyoboro ya MCB ni ingenzi mu miyoboro y'amashanyarazi igezweho, itanga umutekano, uburyo bworoshye, kandi ikora neza. Gusobanukirwa amahame ngenderwaho y'imikorere, amoko yayo, n'inyungu zayo bishobora gufasha ba nyir'amazu n'ibigo gufata ibyemezo bisobanutse ku byo bakeneye mu bijyanye no kurinda amashanyarazi. Uko ikoranabuhanga rikomeza gutera imbere, imiyoboro ya MCB izakomeza kuba inkingi y'umutekano w'amashanyarazi, tukareba neza ko ingo zacu n'aho dukorera birinzwe ingaruka z'amashanyarazi.
