Miniature Circuit Breakers: Uburinzi bw'amashanyarazi mu mutekano

Sobanukirwa uruhare rwaMCBmu buryo bw'amashanyarazi

Utwuma duto tw’amashanyarazi (MCB) ni ingenzi mu buryo bw’amashanyarazi bugezweho, butanga uburinzi bukomeye ku bintu biremereye cyane ndetse n’uduce duto tw’amashanyarazi. Uko icyifuzo cy’ibikoresho by’amashanyarazi byizewe kandi bitekanye gikomeza kwiyongera, gusobanukirwa imikorere n’akamaro ka MCB birimo kugenda birushaho kuba ingenzi ku banyamwuga ndetse n’abafite amazu.

MCB ni iki?

MCB, cyangwa miniature circuit breaker, ni igikoresho cy’amashanyarazi cyagenewe kurinda amashanyarazi kwangirika bitewe n’umuvuduko w’amashanyarazi mwinshi. Bitandukanye na fiyuzi zisanzwe, zigomba gusimburwa nyuma yo guturika, MCB ishobora kongera gusubizwa inyuma nyuma yo kugwa, bigatuma iba amahitamo yoroshye kandi meza yo kurinda amashanyarazi. MCB zikunze gukoreshwa mu mazu yo guturamo, mu bucuruzi no mu nganda kugira ngo zirinde insinga z’amashanyarazi n’ibikoresho bihujwe.

Uburyo MCB ikora

Hari amahame abiri y'ingenzi y'imikorere ya MCBs: urugendo rw'ubushyuhe n'urugendo rwa rukuruzi. Uburyo bwo kugenda kw'ubushyuhe busubiza ikibazo cyo kurenza urugero rw'umuvuduko, aho umuvuduko urenze ubushobozi bw'uruziga mu gihe runaka. Ibi bigerwaho binyuze mu gice cy'icyuma gifata imirasire ibiri, kigenda gihinduka iyo gishyushye, amaherezo kigatera switch yo gufungura uruziga.

Ku rundi ruhande, uburyo bwa rukuruzi butuma habaho imiyoboro migufi y’amashanyarazi, ikaba ari ukwiyongera gutunguranye k’umuyoboro w’amashanyarazi. Muri iki gihe, rukuruzi ikora imbaraga zikomeye z’amashanyarazi zikurura urufunguzo hafi ako kanya, zikarinda kwangirika kw’imikorere y’amashanyarazi.

Ubwoko bwa MCB

Hari ubwoko butandukanye bwa MCB, buri bwoko bufite intego yihariye. Ubwoko bukunze kugaragara burimo:

1. Ubwoko bwa B MCB: Ikwiriye gukoreshwa mu mazu kandi ishobora kwihanganira umuvuduko ukabije. Igwa hagati y’inshuro 3 na 5 z’umuvuduko usanzwe.

2. Ubwoko bwa C MCB: Ubwoko bwa C MCB ni nziza cyane mu bidukikije by'ubucuruzi n'inganda kandi zishobora kwihanganira imiyoboro myinshi y'amashanyarazi, bigatuma ziba nziza cyane ku mutwaro ujyana ibintu ku ngufu nka moteri. Zizagwa ku nshuro ziri hagati ya 5 na 10 z'umuyoboro upima.

3. D-Type MCB: Izi circuit breakers zagenewe gukoreshwa mu mirimo ikomeye nka transformers na moteri nini kandi zishobora guhangana n'imigezi myinshi cyane. Zigwa inshuro 10 kugeza kuri 20 z'umugezi ugereranije n'umuvuduko.

Ibyiza byo gukoresha MCB

MCB zitanga inyungu nyinshi ugereranyije na fize zisanzwe. Ubwa mbere, MCB zishobora kongera gukoreshwa; iyo ikibazo cyakuweho, zishobora kongera gukoreshwa nta zindi. Ibi ntibizigama igihe gusa, ahubwo binagabanya ikiguzi cyo kubungabunga. Icya kabiri, MCB zitanga uburinzi bunoze, kuko zishobora gutoranywa hashingiwe ku miterere yihariye y'umutwaro urinzwe. Ibi bituma ibikoresho byoroheje birindwa nta nkomyi zikenewe.

Byongeye kandi, MCB zizewe kandi zigwa vuba kurusha fiyuzi, bifata igihe kirekire kugira ngo zikoreshwe iyo zirenze urugero. Iyi nyito yihuse ifasha kugabanya kwangirika kw'ibikoresho by'amashanyarazi no kugabanya ibyago byo gushya.

Muri make

Muri make, utumashini duto dukoresha amashanyarazi (MCB) tugira uruhare runini mu kurinda umutekano n'ubwirinzi bw'imikorere y'amashanyarazi. Ubushobozi bwatwo bwo kurinda imitwaro myinshi n'imirongo migufi, ndetse no koroshya gukoreshwa no kongera gukoreshwa, bituma tuba igice cy'ingenzi mu bikorwa byo mu ngo no mu nganda. Uko ikoranabuhanga rikomeza gutera imbere, akamaro ka MCB mu kurinda ibikoresho by'amashanyarazi kazakomeza kwiyongera, bigatuma gusobanukirwa imikorere n'inyungu zabyo biba ingenzi ku muntu wese ukora ibikoresho by'amashanyarazi. Waba uri nyir'inzu ushaka kunoza umutekano w'amashanyarazi cyangwa umuhanga mu by'amashanyarazi, gusobanukirwa MCB ni ingenzi mu isi y'amashanyarazi ya none.
