Intangiriro ku Ihame ry'Umurimo n'Ishyirwa mu Bikorwa rya MCB

Mu bijyanye n'ikoranabuhanga ry'amashanyarazi n'umutekano,utumashini duto two gukata imiyoboro y'amashanyarazi (MCBs)bigira uruhare runini mu kurinda imiyoboro y'amashanyarazi kwangirika cyane no kwangirika kwa amashanyarazi make. Nk'igice cy'ingenzi cy'amashanyarazi yo mu ngo, ubucuruzi, n'inganda, MCB zagenewe guca imiyoboro y'amashanyarazi mu buryo bwikora iyo hagaragaye ikibazo, bityo bikarinda ibyago bishobora kubaho nk'inkongi z'umuriro n'ibikoresho byangiritse.

Ni ikiakamashini gato ko gukata uruziga (MCB)?

Akamashini gato ko gukata umurongo (MCB) ni akamashini gakoresha ingufu zikoreshwa mu kurinda imiyoboro y'amashanyarazi kwangirika kw'umuyoboro w'amashanyarazi. Bitandukanye na za fuse zisanzwe zigomba gusimburwa nyuma yo guhumeka, MCB zishobora kongera gusubizwa inyuma nyuma yo kugwa, bigatuma ziba igisubizo cyoroshye kandi cyiza cyo kurinda imiyoboro y'amashanyarazi. MCB ziboneka mu buryo butandukanye bwo gupima ingufu z'amashanyarazi, ubusanzwe kuva kuri 0.5A kugeza kuri 125A, kandi zishobora gukoreshwa cyane mu buryo butandukanye.

Ni iyihe ngingo ngenderwaho y'imikorere ya miniature circuit breaker (MCB)?

Imashini ntoya zikoresha amashanyarazi (MCB) zikora cyane cyane zishingiye ku buryo bubiri:gushyuha cyanenagukurura magnetic. Gushyuha cyane bikemura ibibazo by’umuvuduko mwinshi. Bikoresha umurongo wa bimetallic; iyo umuvuduko w’amashanyarazi urenze urugero, umurongo wa bimetallic uragonda ugahinduka, amaherezo ugasenya umurongo. Gushyuha cyane bikemura ibibazo by’amashanyarazi mu buryo buciriritse. Bikoresha electromagnet; iyo umuvuduko w’amashanyarazi uzamutse mu buryo butunguranye, electromagnet ikora imbaraga zikomeye za rukuruzi, igahita isenya umurongo.

Ubu buryo bubiri butuma utumashini duto duca imiyoboro y'amashanyarazi dushobora gukumira umuvuduko mwinshi n'imiyoboro migufi, bigatuma tuba igice cy'ingenzi cy'ikoranabuhanga rigezweho ry'amashanyarazi.

Ubwoko bwa Miniature Circuit Breakers

1. Ubwoko bwa B Miniature Circuit Breaker: Iyi circuit breaker ikwiriye gukoreshwa mu mazu kandi yagenewe kugabanya umuvuduko w'amashanyarazi inshuro 3 kugeza kuri 5. Ni nziza ku mpande zifite imizigo irinda imitwaro, nk'amatara n'insinga zishyushya.
2. Ubwoko bwa C Miniature Circuit Breaker: Ubu bwoko bwa circuit breaker bukoreshwa mu bucuruzi no mu nganda kandi bukwiriye imizigo ikoreshwa mu gukurura ibintu nka moteri na transformers. Umuvuduko wayo wo kuzenguruka ni inshuro 5 kugeza ku 10 z'umuvuduko usanzwe, kandi ushobora kwihanganira umuvuduko muke w'amazi udatemba.
3. Ubwoko bwa D Miniature Circuit Breakers: Utwuma duto two mu bwoko bwa D twagenewe gukoreshwa mu mirimo ikomeye, dufite umuvuduko wo kugwa ukubye inshuro 10 kugeza kuri 20 z'umuvuduko w'amashanyarazi. Dukunze gukoreshwa mu duce dufite umuvuduko mwinshi, nka moteri nini.

Ni irihe tandukaniro riri hagati ya MCB na MCCB?
Ubwa mbere, MCB zikoreshwa cyane cyane mu kurinda umuvuduko mugufi no kurinda umuvuduko mwinshi ku muvuduko muke (ubusanzwe munsi ya ampere 100), mu gihe MCCB zikoreshwa cyane cyane mu kurinda umuvuduko mugufi no kurinda umuvuduko mwinshi ku muvuduko mwinshi (ubusanzwe hejuru ya ampere 100). Ibi biterwa n'imiterere itandukanye y'imiterere n'ibikoresho bikoreshwa muri MCB na MCCB kugira ngo zijyane n'umuvuduko n'imizigo bitandukanye. Icya kabiri, MCB zikoresha ibice by'ikoranabuhanga nk'urubingo n'ubushyuhe mu kurinda, mu gihe MCCB zikoresha ibikoresho bya mekanike nk'ibikingira ubushyuhe n'ingufu mu kurinda.

Ibyiza byo gukoresha utumashini duto dukoresha amashanyarazi

Ugereranyije na fuse zisanzwe, miniature circuit breakers (MCBs) zitanga ibyiza byinshi. Icya mbere, MCBs zizewe cyane kandi zisubiza vuba ibibazo by'amashanyarazi. Kuba zishobora kongera gukoreshwa nyuma yo kugwa bigabanya gukenera gusimburwa kenshi, bityo bigagabanya ikiguzi cyo kuzisana. Byongeye kandi, MCBs ni nto kandi zoroshye kuzishyiraho, bigatuma ziba amahitamo meza kuri switchboards zigezweho.

Byongeye kandi, miniature circuit breakers (MCBs) yongera umutekano mu kugabanya ibyago byo gushya kw'umuriro w'amashanyarazi no kwangirika kw'ibikoresho. Imiterere yazo ituma zikora mu byiciro runaka, zigatuma sisitemu z'amashanyarazi zikora neza kandi zikirinda ibyago byinshi.

Muri make

Muri make, utumashini duto dukoresha amashanyarazi (MCB) ni ingenzi cyane mu byuma by'amashanyarazi, bitanga uburinzi bw'ingenzi ku mubyimba no kurinda amashanyarazi make. Hari ubwoko bwinshi bwa MCB bukenewe mu bijyanye no gukoresha amashanyarazi, butanga ibyiza nko kuba bwizewe cyane, koroshya ikoreshwa, n'umutekano mwinshi. Hamwe n'iterambere rihoraho ry'ibikoresho by'amashanyarazi, akamaro ka MCB mu kurinda umutekano w'ibidukikije byo mu ngo no mu nganda ntigashobora kwirengagizwa. Ku bakora mu by'ikoranabuhanga ry'amashanyarazi cyangwa umutekano, gusobanukirwa imikorere n'ibyiza bya MCB ni ingenzi, kuko bifasha mu gutuma imikorere myiza kandi itekanye y'ibikoresho by'amashanyarazi ikorwa neza.
